[ABI] CEM Market $1.3B; Needs Policy and DPI; HP, IBM, Amdocs Lead

A recent research by Aditya Kaul (pictured), practice director, ABI Research concludes that "..  it’s only recently that CEM has been applied in mobile .. sizes the CEM opportunity in 2013 at $1.3 billion across the network and IT domains, although roughly 80% of the market is dominated by the IT domain in areas like BSS/OSS, CRM, and SDP"

The Mobile CEM landscape today is dominated by IT vendors such as HP, Amdocs, and IBM which are leveraging strengths in IT combined with a heavy focus on customer analytics and data mining. However, for CEM to succeed, the network piece including network monitoring, optimization, DPI and policy, has to go hand-in-hand with the IT piece, which is where traditional network vendors come in .. Ultimately, CEM only becomes relevant if done end-to-end, with a single point of ownership within the carrier; something like a NASA mission control with a CEM commander at its helm, having multiple views across Network and IT domains.”

[Vendor Review] Comverse's New Analytics Supported Policy Creation

Just before they leave to MWC, I met two of Comverse's Mobile Internet marketing team - Inbal Ben Ami, Product Marketing Manager, and Haim Rapoport (pictured), AVP Product Marketing.

I used the opportunity for a short brief on Comverse mobile internet business, and to learn more on the new products Comverse will be presenting in Barcelona this year.

Comverse Data Management and Monetization business (formally MIH - Mobile Internet Hub), offers all components of traffic management - from a PCEF (figure 1) with DPI (by ipoque - here), filtering and optimization, through PCRF, to a convergent billing system (Comverse ONE), with full integration between all systems (see figure 2 - 3GPP Sy "and beyond" support for billing-policy management integration).

Figure 1

Figure 2
Comverse is financially strong - with revenues $675M  (Q4 '11-Q3 '12), $250M in cash and no debt. Comverse internet business is no longer focused on the mobile market only, but addresses the fixed market as well, with the PCEF/DPI and policy management offering.

Encouraged by Infonetics Research report, showing that the two most important selection criteria for policy management systems are "Flexibility of rules engine" (96%) and "performance scalability across complex use cases and session/subscriber growth" (88%), Comverse decided to increase the usability of its PCRF rules creation and editing.

On top of the existing graphical rule editing tools provided to the marketing people designing new products (here, figure 3), Comverse adds analytics to assists marketers in their work - "Analytics Supported Policy Creation", they call it. Now, when a new service plan is created, the analytics function may advice on the popularity of the rule defined (figures 4 & 5).

Comverse clarified that the analytics function is not yet commercially available.

Rumors: NSN's Liquid Applications Uses Saguna's Technology

Nokia Siemens Networks announced the "Biggest transformation in the role of the base station since launch of GSM 22 years ago .. Rather than being just part of a commoditized data bit-pipe, Nokia Siemens Networks is turning the base station into a place where any type of content and data can not only be stored but also take advantage of knowing where and why people are using their smartphones and tablets. By placing useful information right at the edge of their networks, at the point where people connect, operators can deliver a far better service and increase the efficiency of their network .. The new innovation from Nokia Siemens Networks is called Liquid Applications.

Rumors are that NSN embedded Saguna's caching and optimization technology in the new product. This seems to be the 4th OEM Saguna's CEO mentioned earlier this month (see "Saguna CEO: "We have 4 New OEM licensees for our Mobile Caching Technology"; Going Live on Q2" - here) after the 3 partners I've covered so far: ADVAFibroLANand Ubiquisys.

Rumors are also that the integrated solution is already in trials by Vodafone and T-Mobile USA (NSN also announced that "SK Telecom, Nokia Siemens Networks collaborate on Liquid Applications" - here).

".. Liquid Broadband provides capabilities to intelligently deliver personalized services to subscribers. End-to-end QoS Differentiation enables operators to prioritize mobile broadband traffic and fine-tune services according to user profiles and applications. With the operator CDN, operators can allocate network resources whenever and wherever required to control the delivery of content right down to the user device. This ensures that the content is delivered with the right priority, in the right format and at the right time.

[Guest Post]: Transforming Subscriber Data into Business Opportunities – Part 2

By Stephane Honore*, Chief Technologist, Openwave Mobility

In the previous post, we described the importance of driving clear ownership and accountability of user data policy and management within the operator organization to truly achieve SDM new monetization opportunities. In this second part, we will see how the trend of centralizing user data from an organizational and political perspective is being reflected in the realms of technology.

Challenged of federated models

Many operators have taken the “quick fix” approach of data federation to provide a virtual logical view of user data and to hide the fact that data is actually stored in a multitude of separate back-ends. The main driver for this implementation is to provide the least disruptive path for achieving logical user data consolidation across the network.

However when such solutions are considered permanent, they jeopardize the long-term ability of the mobile broadband operator to truly transform their user data into monetization opportunities. Hybrid or federated consolidation models have the following fundamental short-comings: 
  • They do not solve the root cause of the data everywhere problem: operators have simply added plumbing software layer on top of their silo’ed services and back-ends. Under the hood no consolidation has actually taken place, neither in the infrastructure nor at the organizational level.
  • Dealing with multiple data backends who have different data models requires complex data processing capabilities to be built in the federation middle-ware; in addition data provisioning and retrieval flows have to take into account failure conditions through challenging roll-back procedures prone to leaving dirty data in the midst
  • Provisioning complexity and lack of true consolidation eventually leads to increased latency as a single request might end up being forked into multiple sub-requests to distinct back-ends before all the replies get compiled into a single response
  • It is not possible to guarantee the overall performance of the solution since the weakest element of a federated infrastructure becomes the weakness of the entire system
3GPP originally advocated the federated SDM models through the GUP server standardization that provided a middle-ware layer responsible for the implementation of data retrieval logic (to determine which back-end a request should be routed to) and access-control definition (to determine who can get which data). Luckily SDM solutions went through a maturation process over 5 years to arrive at the conclusion: true data centralization cannot be realized logically and requires abstraction between the applications and the data store.
Towards User Data Convergence
After having tackled the user “data everywhere challenge” for a number of years, 3GPP eventually settled on a simple architecture known as User Data Convergence (UDC) with the introduction of the User Data Repository component (UDR) and the definition of the Ud reference point towards external application front-ends. The work started in 2009 with the definition of the service requirements (3GPP TR22.985) supported by major Tier1 carriers and reached completion in Rel10 with the UDC technical specification (3GPP TS-29.335) standarizing the UDC architecture. Since then only minor improvements have been added to the now solid and stable UDC foundation, including: 
  • 3GPP TS-32.182 started the definition of objects and relationship (end-user, subscription, servce profile, identifier) towards a Common Baseline Information Model (CBIM)
  • 3GPP TR-32.901 studied the UDC information model handling and provisioning to develop understanding, guidelines, and preliminary requirements for the BSS provisioning capabilities and information model handling when new applications and related services are implemented in the operator’s UDR
As Diameter is becoming a popular transport protocol in mobile broadband architectures, operators also have the option to use a Diameter based interface against the UDR with the 3GPP Sh interface (3GPP 29.329) which initially was used to exchange user profile, location information, and charging function addresses in the IMS realm (between SIP AS and HSS).
Compared to the federated models, the 3GPP User Data Convergence model provides an efficient, mature and standardized way for achieving user convergence without any middle-ware layer as long as front-ends and the UDR back-end talk the same Ud/Sh protocol, something any mobile broadband operator willing to adhere to the UDC deployment model should enforce on vendors. Given the duality between LDAP and Diameter, it is important to takes a best of breed approach with a UDR capable of supporting both stacks on the same software component to avoid the need for deploying new software or even new hardware when the operator wants to make use of the Sh interface in the future. 

Think “push” rather than “pull”
It is often overlooked that the 3GPP UD interface specifications give operators more than a simple data storage and retrieval mechanism. While the main purpose of the interface is to allow any front-end (service or application platform) to query, create or update the user data information over a standard LDAPv3 interface, 3GPP also defined a new synchronization and replication mechanism by permitting front-ends to subscribe to any user data changes happening in the UDR and being notified over a standard HTTP/SOAP interface.
This is an important aspect of the UDC architecture as it goes beyond the traditional pull mechanism for getting updated user data information. This notification mechanism based on a subscription/push model is a game changer as it provides a simple, yet efficient, way to keep local caches/stores synchronized with the centralized UDR master. It provides the possibility of easily implementing new use cases that require a real time view of the subscriber data. As immediacy and instant gratification becomes the standard of Internet services (1-Click real-time experience), mobile operators need to look at new ways to provide real-time self-care capabilities where user self-care interactions immediately take effect on their traffic management or charging infrastructure. Examples of such services include roaming plan sign-up or application-based charging top-up scenarios where service activation immediacy is required.
With 3GPP push-based architectures operators can now consider launching new services that have strong real-time requirements between user interactions and network infrastructure.
Making user data convergence part of the network modernization agenda and executing organizational adjustments to clarify ownership and responsibility of data across the organization are key commitments operators need to make to fully benefit from SDM solutions. Failing to do this they won’t be able to set the growth for the future without solid subscriber data management foundations.

He is also responsible for the SDM product management. Prior to his current role, Stephane held a wide range of leadership roles within the Sales, Engineering and Product Management organizations

[Gartner]: "High-bandwidth DDoS attacks are becoming the new norm"

A new report by Avivah Litan (pictured), VP and distinguished analyst at Gartner, predicts that "..Twenty-five percent of distributed denial of service (DDoS) attacks that occur in 2013 will be application-based .. attackers send out targeted commands to applications to tax the central processing unit (CPU) and memory and make the application unavailable .. High-bandwidth DDoS attacks are becoming the new norm and will continue wreaking havoc on unprepared enterprises in 2013".
"A new class of damaging DDoS attacks was launched against U.S. banks in the second half of 2012, sometimes adding up to 70 Gbps of noisy network traffic blasting at the banks through their Internet pipes. Until this recent spate of attacks, most network-level DDoS attacks consumed only five Gbps of bandwidth, but more recent levels made it impossible for bank customers and others using the same pipes to get to their websites .. To combat this risk, enterprises need to revisit their network configurations, and rearchitect them to minimize the damage that can be done. Organizations that have a critical Web presence and cannot afford relatively lengthy disruptions in online service should employ a layered approach that combines multiple DOS defenses".

Sandvine CTO: "Sandvine achieves the required top-line performance in fewer rack units"

Don Bowman (pictured), Sandvine's CTO, sent me a comment on my coverage of Sandvine's recent product announcement ("Sandvine - New High-End DPI"- here), referring to the way performance numbers should be considered:
"With communications service providers worldwide under pressure to rein in operations costs, performance density is as important a consideration as top-line performance. Fortunately for operators, Sandvine’s PTS offers the best of both worlds without sacrificing either: industry-leading port and performance density combined with clustering technology that efficiently delivers massive scale.  For instance, the PTS 24700 delivers 30 Gbps of inspection throughput per RU under real-world business intelligence, real-time charging and management policy load.  As a direct consequence, Sandvine achieves the required top-line performance in fewer rack units than our competitors, providing considerable operational savings versus alternatives". 
See the DPI Product comparison (here) for rack units, port density and vendor's throughput numbers.  

Cisco: PCRF Performance Improved

 Murali Nemani (pictured), Sr. Director, Service Provider Mobility Marketing, Cisco updates in a blog post about a recent performance test for its (ex. BroadHopQuantum policy manager.

The test, performed by EANTC (see "How did EANTC Test Comverse PCRF?" - here), shows the system has a "linear scale-out to 250K transactions-per-second with 75M concurrent sessions" (see report below).

Cisco UCS 5108
A "system" in this case was up to 6 UCS 5108 chassis, each taking 6RU with 8 UCS B200 blades, with fabric interconnect. For the table below I took the numbers for a single chassis with 6 blades ("initial load") in order to try to compare with the other vendors. Previous test results by BroadHop (here) "Demonstrated support for 28,000 TPS with 16 blades in a single 10U chassis"

See below a short comparison of all tests published so far. Test scenarios, hardware configuration, size and cost are not the same in all tests. Probably even the definitions of TPS (or PDP contexts setups by some vendors) are not equal as well. Please refer to vendor's documentation for more specific information.
