Whitepaper: Traffic Management Techniques for Mobile Broadband Networks Top
Traffic management techniques for mobile broadband networks View more documents from Zahid Ghadialy . The report, Traffic Management Techniques for Mobile Broadband Networks: Living in an Orthogonal World ,focuses on 3GPP networks and concerns itself specifically with traffic management, including the handling of traffic flows on 3GPP networks in contrast with other network management techniques that operators may deploy (such as offloading, compression, network optimization and other important mechanisms). Mobile broadband networks are confronted by a number of challenges. In particular, the physical layer in mobile networks is subject to a unique confluence of unpredictable and unrelated, or "orthogonal," influences. Moreover, mobile broadband networks have some important differences from their fixed brothers and sisters, which lead to different traffic management requirements. Among the most significant differences for purposes of traffic management is the need for more granular visibility to circumstances on the ground. Optimally, traffic management for mobile broadband networks requires visibility to what is occurring (by device or application) at the cell site level and in a timeframe that enables as far as feasible near-time reactions to resolve issues. With the consumer in mind, an End-to-End (E2E) view of mobile service is critical for traffic management. For example, a consumer using a mobile phone to look up movie listings and purchase tickets considers the E2E service as the ability to see what movie is playing and execute a transaction to purchase tickets. 3GPP has endeavored to standardize increasingly more robust traffic management (Quality of Service, or QoS) techniques for mobile broadband networks with a consumer's E2E view of QoS. It must be considered, however, that mobile operators typically do not have full control over E2E provisioning of services that depend on mobile broadband Internet access. Global standards organizations like 3GPP play an important role in the development of traffic management through provisions for addressing QoS, particularly regarding interworking with non-3GPP access mechanisms. These are important new innovations, and the 3G Americas white paper notes that the efforts of standards development organizations should be intensified. In addition, the configuration of end-user devices and content and applications not provisioned by the network operator not only impacts the experience of the particular user, but potentially other users in a particular cell as well. Efforts to drive further QoS innovations should be mindful of potentially adverse impacts from these sources and support and foster interoperability of third party applications with existing network platforms. More innovations are needed throughout the mobile broadband ecosystem, in particular by application developers, in order to realize E2E quality of service. Furthermore, transparency in network management practices is important in fostering innovation, but requires a careful balancing to ensure consumer comprehension while safeguarding network reliability. Organizations with technical expertise such as 3G Americas are prepared to help to illuminate and progress the development of these new technologies. "3G Americas stands ready to assist interested parties in the ongoing development and understanding of traffic management techniques," said Chris Pearson, President of 3G Americas. "We are mindful that in this hemisphere and elsewhere, the industry has accepted an increasingly active role in addressing questions about service levels and innovation on mobile broadband networks." The white paper, Traffic Management Techniques for Mobile Broadband Networks: Living in an Orthogonal World , was written collaboratively by members of 3G Americas and is available for free download on the 3G Americas website at www.3gamericas.org .
 
AT&T on their LTE Backhaul Architecture Top
Backhaul is a topic that may be giving some operators nightmare. Picked up this slightly old article from Light reading via WirelessMoves . AT&T network architect Yiannis Argyropoulos addressed the Backhaul Strategies and Core Convergence for Mobile Operators event in New York City and had the following to say: The lines between wireless and wireline networks are blurring, as are the boundaries between access and core networks, driven by the need to carry the flood of wireless data traffic more efficiently. AT&T is aggressively deploying fiber to its mobile cell sites and migrating from Sonet to Ethernet, but more changes will be needed. AT&T started its fiber push in 2008, and it will take at least seven years to complete, said Argyropoulos. For the short term, today's metro Ethernet architecture will support LTE, but longer term, the network architecture needs to have less operational complexity, noted the AT&T man. The carrier is in the process of testing new approaches, based in part on work being done by 3rd Generation Partnership Project (3GPP) and the Broadband Forum . AT&T also is looking for coordination of policy control between its wireline and wireless networks, so that the core network services are the same for end-users, regardless of how they connect to the network. It is no longer adequate for quality-of-service to be delivered piecemeal, within different segments of the network, Argyropoulos stated: "There is a lot of work going on right now to harmonize these." The early 3GPP scheme for QoS on 3G UMTS networks was too complicated to be implemented, but newer LTE QoS plans from the 3GPP, with nine QoS classes and a smaller number of individual class attributes, look more practical. The growing volume of data traffic is having an impact on other areas of the carrier's operations, too. The widespread use of bandwidth-hungry smartphone devices is creating new traffic patterns that, among other things, eliminate traditional maintenance windows traditionally scheduled in the early hours of weekend mornings, Argyropoulos pointed out. "Data traffic peaks at the same time as voice, but it has multiple peaks, and it doesn't ever really subside," he said. That, in turn, is putting pressure on wireless network operators and their vendors to do hitless network upgrades and to build more resiliency into their networks. AT&T is looking to other means of offloading traffic, including routing optimization that will use gateways strategically placed in the network to direct traffic onto the Internet, and not carry it through the metro and core networks first. "Most of the mobile data traffic is coming from the Internet and going to the Internet." It will also be important to offload subscriber traffic generated in the home onto a domestic Internet connection, he added. To get an Idea of the mobile backhaul load, see my earlier post here . Along with Fiber, Microwave is also an option and you can read more about it in Daily Wireless blog. Also came across this blod dedicated to mobile backhaul, that is available here .
