Segment routing (SR) is a concept that’s been working its way through the IETF standards process but is finally becoming ready for real world deployment. It’s a network technology that provides enhanced packet forwarding behavior while minimizing the need for maintaining awareness of mass volumes of network state. SR satisfies essential requirements for application-enabled routing in software defined networks, including the ability to provide strict network performance guarantees, efficient use of network resources and very high scalability for application-based transactions. Segment Routing relies on a small number of extensions to IS-IS and OSPF and can operate with an MPLS or an IPv6 data plane and integrates with the rich multi-service capabilities of MPLS such as L3VPN, VPWS, VPLS, E-VPN, etc.

Topics such as Software Defined Networking and programmable networks are of great interest to many network operators these days. With that in mind we’re pleased to kick off a new series of Webcasts to help our customer learn more about Cisco’s Open Network Environment strategy.
Please join us on February 14, 2013 (9:00 am PST, 5:00 pm GMT) for an educational webcast featuring David Ward, Cisco CTO, Engineering and SP Chief Architect, and Chair of the Technical Advisory Group at the Open Network Foundation (ONF). It’s a chance to learn more about OpenFlow and its components, the protocol evolution and use cases, as well as its integration into existing networks. Read More »

Yesterday we reprinted the first part of Telecom Asia magazine’s interview with Brian Shoda, director of Cisco NGN architecture sales for Asia Pacific. Here is the second and final part of the story.
4. [Telecom Asia] How can telcos better optimize and simplify their network architectures?
[Brian Shoda] The traditional layered and hierarchical model of network architecture has served operators well for many years. Today, the demands on operator networks are vastly different to those of the past. Optimization and simplification of network architectures is a key focus for most operators. Long lead times for activating new capacity, idle link capacity, and 1:1 bandwidth reservation are all costly methodologies and are no longer feasible for the modern operator.

Last month Brian Shoda, a 12 year veteran of Cisco and most recently the director of Cisco’s IP NGN architecture sales for the Asia Pacific theatre, sat for an interview with Telecom Asia magazine. During the interview he discussed the impact of programmability on the network and why dynamically configuring services is important for telecom operators. Since some of our global audience doesn’t read Telecom Asia magazine they’ve graciously allowed us to reprint the interview.
1. [Telecom Asia] What are the key trends driving the transition in SP networking?
[Brian Shoda] Over the past several years, service provider networking has primarily focused on cost reduction through network optimization and revenue generation and the development of new and innovative products. However, recently with the explosion of mobile data traffic growth many operators have struggled to control capital expenditures as they scale their networks to support demand, often diverting capital from product development to ensure the on-going scalability of the infrastructure. In many markets, this has led to the stagnation of innovation and the commoditization of network services, which, in turn has lowered revenues and reduced margins as operators compete on price to maintain and grow their customer bases.
