DT’s Ian Farrer on the All IPv6 TeraStream Network

A few months back we announced how Hrvatski Telekom, Croatia’s largest telecommunications company, is using a Cisco’s end-to-end solution for its advanced TeraStream cloud-enabled Internet Protocol (IP) architecture. Operated by Deutsche Telekom subsidiary Hrvatski Telekom (T-HT), it’s initially providing broadband services to residential users in the Zagreb area of Croatia.

Segment Routing: Impact on Software Defined Networks

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.

The Impact of Programmability on Networks Part 2

brian shodaYesterday 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.
