Monday's Guest Post: Video Optimization can significantly improve QoE
A new guest post will be published on Monday. In his article, "Using Video Optimization to Improve Quality of Experience" my 22nd guest, Indranil Chatterjee, will discuss the new ways video optimization is used by MNOs.
"Video data traffic has been the thorn in mobile operators’ sides for some time – with issues surrounding how to provide high quality video, without compromising other subscribers’ data usage and the video experience itself. Initially, operators sought out video optimization as a blunt instrument to simply cut down the amount of video traffic across the network. By doing this the quality of all video services was compromised – it was a quick fix to a complicated problem. However, since then video optimization has evolved from the blanket solution it once was and has become more flexible, with intelligent congestion-aware solutions capable of significantly improving subscriber’s Quality of Experience (QoE)" says Indranil.
Stay tuned.

[iSuppli] 1.2B(!) LTE Subscribers by 2016
A new report by Francis Sideco (pictured), senior principal analyst, wireless communications, IHS iSuppli concludes that "Global 4G LTE subscribers this year are forecast to reach 73.3 million, up a whopping 334 percent from 16.9 million in 2011 .. Another round of impressive triple-digit growth, equivalent to 181 percent, is expected in 2013 when 4G LTE subscribers total 205.7 million. By 2016, 4G LTE subscribers will reach nearly 1.2 billion strong, as shown in the figure below .. Subscribers to the older 3G technology will continue to outnumber 4G LTE users, but the pace of growth for 3G will be significantly slower and not exceed 35 percent at any point from this year onward".
Previous reports predicted 802M LTE subscribers by 2017 (Pyramid - here) or 430M by 2016 (older report, Juniper Research - here).

PCC (w/Device Awareness) Win for Comptel
"Comptel’s bespoke device detection solution enables the mobile operator to not only sell data plans at a reduced price to satisfy customers, but also limit subscribers’ usage to specific tablets, so that SIM cards will not be misused and affect its unlimited data plans. The mobile operator has implemented a tiered alert system to notify customers when it finds that the SIM cards have been used on unauthorised devices like 3G modem dongles, and discontinue their data service following a third warning .. Comptel successfully delivered the project, which involved OCF implementation and DIAMETER Gy integration, on time in less than 12 weeks and to the operator’s specifications".
Ulla Koivukoski [picutred], SVP Marketing and Communications, provided me with some more details on the solution:
"This solution is based on Comptel EventLink and Comptel Control and Charge, but part of the implementation has been tailored based on the customer specific requirements. It was using IMEI (no DPI), but Gy Diameter interface with GGSN and using lookups to map to devices and subscriber subscription In SPR to understand whom and when to apply this control".

Telus Sees 2,700% Signaling Growth Y/Y
Perry Hoffman reports to Cartt.ca on the "'tsunami of traffic' resulting from very high levels of social media over wireless devices and the connectivity of an increasingly large number of those devices is forcing mobile operators to deal with growing congestion. This was one of the key messages from Eros Spadotto (pictured), executive vice-president of technology and operations at Telus during a keynote presentation to the Institute of Electrical and Electronics Engineers (IEEE) InternationalConference on Communications on Tuesday in Ottawa".
"The reality is that while our megabytes of traffic is increasing, the signaling from these devices is greatly overwhelming that. In fact, we can look at a period of time where our growth has been 100% year over year on payload, on how many megabytes, but our signaling has grown 2,700%".
"It’s not just about getting more spectrum .. it’s about making it useable by the operators so they can build faster networks to deal with the onslaught of richer, bandwidth intensive applications being used over increasingly sophisticated mobile devices".
At the end of Q2 2012, Telus had 7.4M wireless subscribers; 39% of its ARPU came from data services during Q2, compared to 33% on the same quarter the year before (see chart).

[F&S]: MSSP Market to Reach $15.6B in 2016
A new research by Martha Vazquez (pictured), Industry Analyst, Frost & Sullivan concludes that "Enterprises are becoming increasingly exposed to organized cyber crime rings and for many businesses, the complexity of threats have compelled them to turn to managed security service providers (MSSPs). These types of external service providers enable organizations to maintain strong security while improving business efficiencies and minimizing costs".
"Although there are many benefits, MSSP vendors are typically challenged when trying to demonstrate the possible savings accrued through working with a trusted MSSP. MSSPs have to educate end users about the advantages of outsourcing security. In response to the escalating demand for broader platform support and more flexibility, MSSPs should also provide a wide range of new security technologies and enhanced security portfolios"
"..Analysis from Frost & Sullivan , Analysis of the Global Managed Security Service Providers Market, finds that the market earned revenues of $6.66 billion in 2011 and estimates this to reach $15.63 billion in 2016 .. The Frost & Sullivan study covers local, regional and global MSSPs such as Nuspire, IBM, Verizon, Dell Secureworks, Solutionary, BT Global Services, Deutche Telecom, MegaPath, and Windstream (formerly PAETEC)”.

Universities Research Mobile Video Quality Measurement
"Because viewers perceive quality differently depending on what they're watching - sports versus talking heads, for example - quality isn't about throughput but experience .. Measuring subjective video quality is only the first step toward the larger goal of delivering high-quality video while boosting network capacity to handle the ever-increasing flood of data. The issue can’t be ignored: In 5 years an estimated 90% of Net traffic will be video, and 66% of mobile traffic will be video"
"The project is now in year two of its three-year, $1.1 million-per-year plan. By then end of the program, the VAWN team hopes to have a good method to measure perceived video quality, as well as algorithms and software tools to use that measurement to make network decisions".

Tekelec Comments on Verizon's PCC Source
Following my earlier post on Verizon Wireless' home grown PCC solution for its Shared Data Plans (here), I asked Tekelec (PCRF and DSR supplier for Verizon) for a comment.
Tekelec spokesperson, Joanne Steinberg (pictured), provided me with the following statement:
"Operators are hoping to play a big role in personalization of services and it is critical that they start leveraging what they know (or can know) about subscribers’ usage patterns, preferences, locations, and circumstances.
Based on our experiences with over 55 Policy customers globally including 43 Tier 1s, most operators will opt to source solutions from outside vendors, but some may have the wherewithal at the early stages to do some of it in-house. Of paramount importance will be access to real-time data from networks and subscriber data management (SDM) systems. The goal is to balance data and signaling traffic in a way that optimizes the customer experience based on customer preferences and the value they place on the services. Central to that will be Policy solutions (PCRF), which define the rules for new services for different subscriber segments based on operator network requirements and marketing strategies".

Light Reading: Verizon Uses Home Grown PCC for Shared Data Plans
Analysts say that Shared Data Plans are important for MNOs business, but require significant IT (PCC) infrastructure (see "OVUM: Shared Data Plans are "here to stay"; Require Management Tools" - here and "Infonetics: Shared Data Plans - an Opportunity with OSS Needs" - here).
So who leads this market? for example which vendor was selected by Verizon Wireless, one the world's largest MNOs and strong believer in shared data plans (see "Verizon: Why Shared Data Plans are Good for Our Business" - here)?
Sarah Reedy (pictured) reports to Light Reading that Verizon Wireless recent shared data plans are based on its own development!
"Behind the scenes, as it manages almost 100 million subscribers on its network, Verizon's Policy and Charging Rules Function (PCRF) must be tied to its billing systems and the data from all the devices on all the plans it manages must be compiled, managed and reconciled to avoid billing mistakes. The cost of making things easier for consumers is that you make things complicated somewhere along the way .. And what vendor is Verizon entrusting with this complex policy management? No one, actually. We asked, and a Verizon spokeswoman led us to believe the move to share data plans, and all the complexity it brings, is handled by Verizon".
Sarah also mentions Tekelec, as a PCRF (and Diameter signaling router) supplier to Verizon's LTE network (see "How does/will Verizon Wireless Use Tekelec's Diameter Router?" - here).

How do CSPs Spend IT Budget?
A new report by Johanne Mayer (pictured), Senior Analyst, and Larry Goldman, Partner, Head of Telecoms Software Research, Analysys Mason concludes that "Communications service providers (CSPs) spent USD119 billion on telecoms IT worldwide in 2010, which represents 6.2% of the telecoms revenue of USD1.9 trillion".
"Our analysis shows that incumbent CSPs with fixed and mobile services spend seven times more than any other type of CSP (that is, fixed- or mobile-only) and that mobile CSPs in developed countries spend USD26 per subscriber per year on IT, compared with USD4 per subscriber per year for those in emerging countries".
"Spending on OSS/BSS accounted for half of total IT spending worldwide – USD59 billion in 2010 .. One-third of the money CSPs spent on IT in 2010,USD38 billion, was spent by the CTO or network/product group on SDPs and apps, and on network management systems (NMSs)".

[Pyramid]: 802M LTE Subscribers by 2017; US, Japan and South Korea Lead
A new research by Pyramid Research forecasts much higher growth for LTE adoption than previously forecasted.
The report concludes that "LTE subscriptions globally increased more than fourteen fold, to 11.4m, and Pyramid Research expects that figure to reach 54 million by year-end 2012, representing less than 1% of total subscriptions. By 2017, Pyramid expects the number of LTE subscriptions to reach 802.2 million, a 72% CAGR over 2012 levels, growing to almost 10 percent of global mobile subscriptions"
Previous reports were more modest - see "[Juniper Research]: 430M LTE Subscribers by 2016" - here.
"Although LTE subscription penetration in the Asia-Pacific region will remain lower than the global average, two countries in the region — Japan and South Korea — are leaders in LTE adoption, surpassed only by the US in current and expected new subscriptions in the next three years. By 2017 China and Indonesia will be important growth markets. Latin America will also continue to show lower LTE penetration than the global average. We expect almost 7% of mobile subscriptions in Brazil to be LTE by 2017, making the regional giant an important driver of global growth in LTE, despite lower than average adoption".

AT&T Says it doesn't Violate Net Neutrality with its Facetime Policy
A blog post by Bob Quinn (pictured), SVP Federal Regulatory and Chief Privacy Officer, AT&T claims that AT&T does not violate FCC' Net Neutrality rules when it will block Facetime over 3G for customers not subscribed to the shared data plans (here).
"Providers of mobile broadband Internet access service are subject to two net neutrality requirements: (1) a transparency requirement pursuant to which they must disclose accurate information regarding the network management practices, performance, and commercial terms of their broadband Internet access services; and (2) a no-blocking requirement under which they are prohibited, subject to reasonable network management, from blocking applications that compete with the provider’s voice or video telephony services.
AT&T’s plans for FaceTime will not violate either requirement. Our policies regarding FaceTime will be fully transparent to all consumers, and no one has argued to the contrary.
There is no transparency issue here. Nor is there a blocking issue"

Israel Expands Net Neutrality to Fixed Networks
The Israeli Ministry of Communications published a draft amendment to the Communication Law, expanding Net Neutrality regulation to fixed services.
Israel adopted NN regulation to wireless services in December 2010 (see "Net Neutrality [Israel] - Parliament Approved Wireless Neutrality" - here).
The draft proposal ("Telecommunication operators will be obliged to guarantee the principle of network neutrality and telecom equipment neutrality - here in English; full proposal here in Hebrew) demands that communication service providers of all kinds will not limit or block any service or application provided over the internet (including VoIP, file sharing and video), limit or block features of communication equipment (including by setting special fees), limit or block the use of communication equipment in any licensed network.
Exceptions are limitation or blocking of service or application done in ensure proper and fair network management, or when the Minister of Communication allowed it "in special cases".
In addition, the draft says that all importers, distributors or sellers of communication equipment will also conform to Network Neutrality and will allow consumers to use all features the equipment they sell or maintain.

[Analysys Mason]: DPI and PCC Needed in the RAN
A new report by Patrick Kelly (pictured), Research Director, Analysys Mason, concludes that "IP and Ethernet technology provides networks with flexibility to scale up in order to support traffic growth as mobile operators deploy lower-cost IP-based radio access technology. Furthermore, growth in mobile data services has also put pressure on mobile operators to reduce their backhaul cost, and many mobile operators are dealing with the difficulty of assuring quality of service and keeping operational costs under control".
".. deep packet inspection probes in the radio access network working together with the policy charging and rules function helps regulate traffic coming through the backhaul network, enabling mobile operators to avoid network congestion problems"

How to Build DPI Products? (Part XVIII - Multi-pattern Matching Algorithm for DPI)
Abstract
Detection engines capable of inspecting packet payloads for application-layer network information are urgently required. The most important technology for fast payload inspection is an efficient multipattern matching algorithm, which performs exact string matching between packets and a large set of predefined patterns. This paper proposes a novel Enhanced Hierarchical Multipattern Matching Algorithm (EHMA) for packet inspection. Based on the occurrence frequency of grams, a small set of the most frequent grams is discovered and used in the EHMA. EHMA is a two-tier and cluster-wise matching algorithm, which significantly reduces the amount of external memory accesses and the capacity of memory.
Using a skippable scan strategy, EHMA speeds up the scanning process. Furthermore, independent of parallel and special functions, EHMA is very simple and therefore practical for both software and hardware implementations. Simulation results reveal that EHMA significantly improves the matching performance. The speed of EHMA is about O.89-1,161 times faster than that of current matching algorithms. Even under real-life intense attack, EHMA still performs well.

According to Dan Rayburn (pictured), EVP StreamingMedia.com, at least one major carrier may have changed his strategy - "After many years of AT&T trying to sell their own CDN services into the enterprise, multiple sources tell me that AT&T has decided that it makes more sense for them to simply re-sell CDN services from either Akamai or Limelight. Both vendors are currently in negotiations with AT&T bidding on the business and while AT&T has not yet picked a winner, I’m hearing that even though Limelight had been favored to win the deal, the reseller business is now Akamai’s to lose".
