Nokia's solution includes:

• "Nokia Liquid Applications’ throughput guidance helps content providers optimize their transmission policy to reflect dynamically changing network resources in real-time. This improves resource utilization in mobile operator's network. YouTube has successfully conducted lab tests of the throughput guidance technology, with initial results showing improvement in network utilization and application quality of experience.

• Congestion detection from Nokia’s Liquid Applications notifies upstream content providers and mobile device clients as to the most efficient time to fetch subscriber content based on real-time cell load information. Akamai, a leading content delivery network (CDN) and cloud computing services provider, is currently testing congestion detection as part of their Predictive Video over Cellular (PVoC) optimization solution for mobile networks.
   
• Nokia smart location experience optimization service provides up to 50% increase in video streaming speeds for consumers based on insights on how applications utilize network resources".

Lior Netzer [pictured], VP and General Manager, Emerging Mobile Business Unit, at Akamai, said: “Akamai’s PVoC video optimization solution is being designed to work with Nokia’s Liquid Applications to intelligently deliver video content at the most optimal times across the mobile network. It makes use of radio context information to initiate video downloads and pre-position content on the mobile subscriber’s device, enabling high quality media experience. Having insight into the real-time capacity levels of the cellular network can result in more efficient utilization of mobile networks.”

Verizon Wont Optimize LTE Congestion by Temporary Throttling

Back in July Verizon announced that it will ".. expand its existing Network Optimization to include unlimited data customers who use 4G LTE devices .. when an unlimited data customer meets specific criteria and hops onto a cell site that is experiencing high demand. This is only a temporary reduction, not a billing cycle throttle. Once that customer leaves the cell site under stress, their connection should return to normal" (see "Verizon Expands "Optimization" to LTE Subs to Fight Cell Congestion" - here).

Something has changed, and Verizon announced recently that "We’ve greatly valued the ongoing dialogue over the past several months concerning network optimization and have decided not to move forward with the planned implementation of network optimization for 4G LTE customers on unlimited plans. Exceptional network service will always be our priority and we remain committed to working closely with industry stakeholders to manage broadband issues so that American consumers get the world-class mobile service they expect and value"

Verizon "Network Optimization Practices for Customers with Unlimited Data Plans" (here) is yet to be updated. It explains the optimization practice ("To optimize our network, we manage data connection speeds for a small subset of customers – the top 5% of data users on unlimited data plans – and only in places and at times when the network is experiencing high demand") but excludes only some LTE customers ("Only a small percent of customers will be affected. To be affected, you must be a data customer on an unlimited data plan who is among the top 5% of data users. Network Optimization of 4G LTE devices does not apply to government customers or business customers who have signed a major account agreement").

Procera Revolutionizes Location-based Mobile Traffic Management

Current congestion management and analytics solutions for mobile networks are usually based on core network located products, and are only partially aware to the real time location and congestion status of each user and base station. 

Some DPI and PCRF vendors announced solutions and partnership to overcome the lack of real-time  information, usually with the help of probes deployed in the access network (Sandvine; Flash Networks; Allot-Amdocs; Sandvine-RADCOM ; Amdocs-RADCOM; HP-RADCOM).

Procera Networks is announcing today a new solution and concept, based on QoE and real time location measurements taken at the User's device - in a crowd sourcing fashion. Subject to cooperation by the users, this can lead into a much more accurate traffic management solution, implementing a real "reasonable network management" policy with real-time and long-term capacity management options. 

Procera announced the "..launch of RAN Perspectives, a ground-breaking new Subscriber Experience solution for mobile broadband operators that delivers real-time location and RAN QoE awareness. RAN Perspectives is a software solution that provides real-time location and radio access network (RAN) quality of experience (QoE) data that can be leveraged to enhance the mobile broadband experience for consumers .. dramatically reducing their deployment of probes and the costs associated with drive testing while expanding their visibility into the RAN in real-time to gain insight and take action .. RAN Perspectives is available for beta testing, and is expected to be generally available in the first quarter of 2015"

Shira Levine, directing analyst, Service Enablement and Subscriber Intelligence, Infonetics Research said: “A device-based solution such as RAN Perspectives has the potential to more effectively manage congestion while enabling a broad array of additional services, solutions and applications, which could have dramatic implications for mobile networks.”

"Unlocking real-time location awareness and RAN signal quality measurements opens up a number of operational and service opportunities that Procera will roll out over the next 12 months, with the initial offerings including:

• Customer Care Insights solution with integrated RAN and IP mobile broadband-centric subscriber diagnostics for customer care teams
• RAN Perspectives-based view for Insights that delivers analytics for quality, congestion, applications, and out-of-coverage hotspots in the mobile network for marketing and engineering teams.
  
• RAN congestion management based on real-time location awareness to identify and take action on congested areas, enhancing subscriber QoE.
  
• Location-based service plan offerings including location-specific policy enforcement and charging for marketing teams.
  
• Crowd-sourced minimized drive testing and out of coverage registration for RAN engineering teams"

Verizon Expands "Optimization" to LTE Subs to Fight Cell Congestion

3 years after Verizon established its optimization policy to reduce cell congestion, [see "Verizon Explains its "Network Optimization" Policy" - here] it is now expanded to LTE.

Kellex reports to DroidLife that "On October 1, Verizon will expand its existing Network Optimization policy to include unlimited data customers who use 4G LTE devices and “have fulfilled their minimum contract term.” That “optimization” occurs when an unlimited data customer meets specific criteria and hops onto a cell site that is experiencing high demand. This is only a temporary reduction, not a billing cycle throttle. Once that customer leaves the cell site under stress, their connection should return to normal.

Update: The policy is changing somewhat on how long you could be throttled. From information we have received from sources (and now reflected on Verizon’s own policy), the throttling could last through a current billing cycle and on to the end of the next, should a user be on a cell site experiencing high demand. This is the exact wording for the potential throttling – “The customer may continue to be impacted for the rest of the current billing cycle and through the next billing cycle, but only while on a cell site that is experiencing high demand.”

Verizon's Optimization Policy page (here) says that "95% of our data customers are not impacted. The top 5% with devices on unlimited data plans may experience managed data speeds when connected to a cell site experiencing high demand after reaching certain data-usage levels in a bill cycle. These high data users will feel the smallest possible impact and only experience reduced data speeds when necessary for us to optimize data network traffic in that area"

Accedian F-FLO Optimizes Wireless Backhaul Network Performance in Real-time

 
Accedian Networks introduced its new " .. solutions group, called Performant Networks; which offers a Wireless-Aware™ SDN product line that optimizes performance in real-time on fixed-wireless networks. This is accomplished by dynamically shaping traffic when link capacity suddenly changes due to real-world conditions such as adverse weather and RF interference.

..

Sandvine Partners with RADCOM for "true mobility awareness"

In a post I had in early 2012, I presented Sandvine's "Mobility-aware Traffic Management Analytics and Enforcing" (here), quoting Sandvine's CTO saying that "Sandvine interoperates with 3rd party partners, such as RAN-based probes, to get the cell (or sector) handovers updates. Sandvine will expose the partners soon".

So the time has come, and Sandvine announced it has "partnered with RADCOM to deliver the only network policy control products with true mobility awareness. Sandvine’s Fairshare Traffic Management product, integrated with RADCOM’s QiSolve solution, offers a dynamic control system that utilizes real-time subscriber location indicators to precisely maximize network utilization and quality of experience. Sandvine’s empirical data demonstrates that traffic management products without real-time location awareness may “lose” up to 20 percent of users in an hour, and mismanage traffic as a result".

Indeed, most location-aware traffic shaping solutions are only aware of the initial location of the subscriber at connection time and do not support mobility. Therefore they may make the wrong conclusions about cell congestion and do not set the right policies to avoid congestion (or avoid setting the right policies..). 

Nevertheless, similar partnerships were established by RADCOM with PCRF products from Amdocs (here) and HP (here).

Sandvine’s Fairshare Traffic Management product recently measured, using RADCOM’s QiSolve solution, the movement of over 20,000 mobile data subscribers in a major North American city to understand and predict sector-based congestion. Over the course of the hour, roughly 20 percent of users were still engaged in the same data session but had moved to a second cell sector. No two sectors have an identical congestion profile at a moment in time".

[Strategy Analytics]: SDN can save MNOs more than $4B CapEx by 2017

   

A new study by Sue Rudd [pictured], Director, Service Provider Analysis, Strategy Analytics (sponsored by Tellabs) finds that "SDN can save mobile operators more than $4 billion in capital expenses by 2017. Savings stem from 5 key SDN applications for mobile backhaul networks [see below]".

The highest % of savings relates to Wi-Fi Offload and video redirect (over $1B). 

"The Tellabs Congestion Control Application, which it demonstrated earlier in 2013 [here], is one example of SDN in action. The application applies SDN to head off bottlenecks and reroute traffic in the backhaul network before users are aware of any problems with their service. For this demonstration, Tellabs’ approach was to add the SDN controller to its existing Tellabs® 8000 Intelligent Network Manager. This means that customers can deploy SDN seamlessly without the need to rebuild the network to achieve the advantages that SDN brings"

Allot-Amdocs Solution for Cell Congestion

A recent report by HeavyReading concluded that "RAN Congestion is Getting Worse" (here) and that "A majority of operators want real-time or near-real-time information on congestion when applying controls".

A number of vendors, usually based on partnerships between networking devices and policy control offer solutions to the problem (see Vasona,  RADCOM/HP, RADCOM/Amdocs, Movik, Sandvine, Broadband Systems). 

Allot Communications and Amdocs published a presentation explaining their joint solution for policy-based cell congestion (note that the subscriber location is noted only when the session starts).

Accedian Adds Multi-vendor Visibility to SON and SDN

Accedian Networks announced SkyLIGHT thart ".. provides mobile operators with the visibility they need to optimize backhaul performance in real-time .. SkyLIGHT delivers operators with the performance visibility required to take the self-optimization promise of SDN and SON and execute it on multivendor, heterogeneous, mobile backhaul networks (MBH-SON) using standards-based technology – a first in the industry. As Accedian currently has partnerships in place with most major base-station vendors, this makes SkyLIGHT, not only standards-based, but also fully interoperable by-design, with more than 80% of the base-stations on the market".

KDDI Explains Data Outage and Actions

A recent presentation by Takashi Tanaka (picture), President, KDDI, explaining the network service outages and the action taken.

• A reset bug related to fragmentation processing (April 27) caused 6:17 hours of service loss, affecting 590K subscribers.
  
• Hardware failure occurred when uploading to one MME port a correction file to resolve the failure that occurred on April 27. caused two days later 18:43 hours of outage, affecting 560K subscribers
  
• Trying to fix it again, on April 30, caused 9:58 hours of outage, affecting 640K subscribers. 

[Survey]: RAN Congestion is Getting Worse

  

A new research by Graham Finnie, Chief Analyst, Heavy Reading (and Movik Networks) finds that "the majority of operators believe RAN congestion is getting worse, with half saying it is also less predictable .. the main objective of new RAN controls is to improve the customer Quality of Experience (QoE) .. and the need to improve the quality of operators’ key services, from controlling signaling congestion, to improving understanding of subscriber behavior and to monetizing features like QoE"

"Other key findings from the study 

• A majority of operators want real-time or near-real-time information on congestion when applying controls
   
• Operators want any controls to be applied holistically across all the networks they owned, with seamless control between 3G/4G and WiFi the biggest motivator
   
• Operators are looking for alternative, cost effective solutions to deploy RAN congestion control measures".

NSN Video Optimization Reduces load by 25%

While the video optimization shows some weakness (Bytemobile, Allot),  Nokia Siemens Networks launched " a combined video optimization solution that delivers a high quality video experience while simultaneously reducing radio network loading by up to 25%. By combining the capabilities of Flexi Content Optimizer, policy management and new real-time congestion awareness, which is unique to Nokia Siemens Networks, operators can match video quality to each user's device.

Flexi Content Optimizer adjusts video content and re-scales video streaming to match the smartphone screen size. Users enjoy the best quality video that their smartphones and tablets can support, and because less data is transferred, there is less pressure on radio network capacity. This translates into more efficient use of radio network resources, and lower transmission costs and network investment.

Real-time congestion awareness enables the network to react instantly when a base station becomes heavily loaded. Video optimization then ensures that the operator’s most valuable subscribers in a specific location enjoy the best video quality".

ADVA Takes Saguna to the Mobile Backhaul

   

ADVA's FSP150CC 

As I mentioned last week (see "ADVA Optical Acquires Biran High Tech Advisors" - here), ADVA Optical Networking announced  its new Cachejack technology - integration of Saguna's CODS caching and optimization technology in its mobile backhaul/carrier Ethernet products for LTE.
 
This is the 3rd OEM announced by Saguna's partners, following Ubiquisys and FibroLAN. See also "Saguna CEO: "We have 4 New OEM licensees for our Mobile Caching Technology"; Going Live on Q2" - here.

   

"Cachejack™ is designed to improve mobile user experience and enable location-based services (LBS) through an application-aware radio access network (RAN) and optimize resource utilization by uniquely transporting content directly from the backhaul network straight to the mobile subscriber .. The ADVA Optical Networking solution loads popular content on integrated cache servers in cell site gateways or network interface devices (NID). That content is then delivered from a cache server, which is in closer proximity to the requesting user than the mobile core network".  

 
Christoph Glingener (pictured), CTO, ADVA Optical Networking said: “We made a strategic investment last year in Saguna Networks [see "Saguna's Investor: ADVA Optical Networking ($1M, 10%)" - here] and its technology for optimizing content delivery in mobile backhaul infrastructures, and now we have rapidly integrated this capability into our successful FSP 150 product line .. Improving user experience, enabling new revenue-generating LBS and reducing transport costs are of prime value to today’s mobile operators”

[Vendor Review]: Vasona's Cell Traffic Management

Biren Sood (Left) and Nery Strasman

Vasona Networks went out of stealth mode recently, announcing its SmartAir 1000 system (here).

To learn more on the company's offering, I met Biren Sood, CEO and Nery Strasman, CTO, in their R&D center in Tel-Aviv.

"We both came from making the cable networks better" (at Bigband, now part of Arris) says Biren, "we want to do the same to mobile networks".

Vasona claims it has founded a new category of products, with the ability to manage mobile traffic at the cell level with application-aware traffic management. I covered before a number of solutions from DPI companies claiming to do the same, but none is actually fully aware of all dynamic cell conditions, load and capacity - mainly because DPI system are installed at the core network where there is no visibility to the cell conditions.

Vasona's software optimizes traffic on mobile access networks (3G and 4G), runs on Intel-based servers, located between the RAN and the core network. Few dozen servers are needed to cover large networks, and offer a unique visibility into the cell conditions (our "secret sauce", says Nery "we understand the reception conditions for the devices connected at the cell"), capacity and identification of the applications used by the subscribers. Rules (policies) are set to define the actions taken when congestion occurs, and to optimize the user's QoE (with business considerations, I assume).

"We are not competing with DPI" says Biren "we add the visibility DPI systems do not have at the Core network's Gi interface, and we do not offer features like caching, video optimization, or content filtering as DPI system do. We focus on 3 things: mobility, high packet processing capabilities and media - the type of application used by the subscriber (video, voice, date etc)". 

Vasona's first version is "self-contained" - the traffic management rules are defined by the operator and set in the product by Vasona's team. Vasona says that they can integrate it with standard PCRF systems (using 3GPP Gx interface) , although they haven't seen market demand for that yet and are not sure that current PCRF systems will be able to support the scale needed,

Vasona has 30 employees and the system is in field trials with Tier-1 mobile operators.

Vendor Preview: FibroLAN's Small Cell Backhaul w/Cache

 
Earlier this week I mentioned the Saguna-FibroLAN partnership (see "Saguna CEO: 'We have 4 New OEM licensees for our Mobile Caching Technology'" - here) in which FibroLAN licensed Saguna's caching and radio optimization software (CODS) for its second generation Falcon series for LTE mobile backhaul (here).

I asked FibroLAN's CEO, Shamir Stein (pictured) to further explain the new solution, that places popular data as close as possible to the users.

Shamir provided the following details about the new product:

• FibroLAN's carrier Ethernet backhaul products support indoor and outdoor small cell deployments. Among other features it provides Power over Ethernet (PoE) to the small cells, and centralized synchronization using an integrated GPS.
   
• Content caching, based Saguna's code, uses SSD storage and handles any kind of content (including video). It promises savings of up to 50% on backhaul bandwidth, while speeding up content delivery. It also supports DNS caching, eliminating the need for round trip delays associated with DNS queries (which could be significant, mainly for web pages with multiple objects).

• The product aggregates several cells, in a flexible model that combines daisy chaining and star topologies. It also supports a campus configuration - in this case the the caching become even more efficient resulting from the larger number of people using it. 

• FibroLAN will demonstrate the new product line at MWC 2013, and availability is planned for Q2 

 
   

Mobixell Announces Embedded LTE/RAN Optimization and Caching Technology

I had several posts on vendors announcing RAN based optimization and caching solutions, such as Saguna/ADVA (here), RADCOM with HP (here) and Amdocs (here) and Sandvine  - here - all trying to solve radio and/or backhaul congestion problems. 

   

Mobixell Networks announced its own solution and similarly to Saguna it offers enabling technology to vendors of base stations/backhaul vendors, for LTE technology. 

The vendor says it has ".. deployed their Radio Access Network (RAN)-based optimization solution in the LTE access network of a leading European mobile operator as a proof-of-concept field test. This solution includes Mobixell Seamless Access video optimization, which enables operators to optimize video both in realtime and offline with built-in video caching of popular content. It was developed in cooperation with a major telecom infrastructure vendor, and integrated directly into their eNodeB, the network element that interfaces directly with end user devices"

Mobixell explains that "Mobile network traffic management is traditionally performed in the core network. There are, however, advantages to moving data optimization and caching out to the access network, closer to end user devices. Fewer backhaul resources are required for traffic management and detection of congestion at the cell site is more accurate. Accurate congestion detection is a critical component in ensuring that optimization resources are applied only to data that contributes to the degradation of network performance. By performing congestion analysis and optimization close to the end user’s devices, operators can more confidently deliver high-quality data services as a part of a satisfying customer experience. As LTE proliferates, and end user expectations for speed and performance increase, the importance of these advantages is multiplied"

Optimization Deployments [209]: Maxis [Malaysia] Saves Backhaul Bandwidth w/Altobridge

Altobridge announced ".. the first commercial deployment of its Data-at-the-Edge solution, an intelligent, content delivery architecture that brings content closest to the end user, i.e., at the radio base station level .. The solution is live on a Tier One wireless network in Asia and results show savings of over 40% in mobile broadband backhaul costs, plus a dramatic improvement in Quality of Experience (QoE) and seamless integration into the live network".

According to Mobile Europe, the customer is the Malaysian operator Maxis (see "Optimise at the edge for '40% backhaul savings'" - here). At the end of Q3, 2012, Maxis had 12.8M revenue generating subscribers. Mobile and broadband data contributed 25.9% of total mobile revenues.

"Data-at-the-Edge™ enables data passing between an operator’s core network and the radio base station to be identified, managed and optimized at the most granular level. This is achieved through content ‘On-loading’ at the base station, data stream de-duplication, data compression and Network Interface Protocol Optimization, along with other data optimization techniques".

With the DatE™ feature-set positioned on both sides of the transmission link, user data is minimized in terms of bandwidth requirements, while caching and pre-positioning features further enhance the solution. Importantly, however, proprietary signaling and voice signaling are left unaltered. This approach (see below) enables E911 Lawful Intercept and billing requirements to be maintained.

Further optimization of this solution allows expansion of the data “on-load” capability (see below), resulting in significant savings and heralding the arrival of new financial business models for network operators.

See "Altobridge Proves 40% Data Backhaul Savings with Intelligent Content Delivery in Commercial Wireless Networks" - here.

Optus Tests Connectem to Manage Cell Congestion at Peak Usage

Optus announced that it has ".. begun a trial of cloud-based mobile packet core technology at its Macquarie Park campus (pictured). The technology has the potential to deliver a higher level of network performance for customers during peak usage periods, such as at major sporting events or music festivals. Through a partnership with mobile virtual infrastructure vendor Connectem, Optus aims to rapidly deploy network capacity to address short, intense spikes in network traffic – with customers benefiting from the increased connectivity on their smartphones and tablets".

Connectem was founded by industry veterans in 2011. Its VCM (Virtual Core for Mobile) platform "employs innovative solutions to avoid congestion and signaling storms while high priority users are assured access .. As an example, with VCM software an ‘attach’ request from a device can be processed at least four times faster and thereby improving the overall network's admission rate. Traditionally, data communication is typically user initiated towards the network. As use cases for network to device communication emerge such as M2M communication, today's signaling assumptions will no longer be valid". 

Nishi Kant, CEO, Connectem, said, “Connectem is working with some of the world’s largest mobile network operators and we have been encouraged by the interest in our technology. In Australia, we welcome the initiatives that Optus is taking in the area of cloud-based network infrastructure”
