Segment Routing Deep Dive with Bertrand Duvivier - Podcast

Segment Routing is the term widely used in the industry to refer to Source Packet Routing In Networking (SPRING), as defined by the Internet Engineering Task Force (IETF). Cisco has pioneered Segment Routing since 2012 and has led the standardization efforts with the support of a group of lead operators, resulting in few RFCs and over 50 active internet-drafts.
In this podcast today, we’re going to deep dive into some technical aspects with Bertrand Duvivier, Principal Engineer from Cisco.

Segment Routing and 5G - Podcast

5G brings in significant changes to the mobile architecture. It relies heavily on virtualization and containerization, splits the mobile control and user plane and introduces network slicing. In the radio space new spectrum is available and the Radio Access Network infrastructure has been de-aggregated into three discrete components that can be integrated into a single unit or split across different locations.
This podcast is going to concentrate on the transport network and how segment routing can address the new requirements and changes brought in by the 5G mobile architecture.

SRv6- A new approach for the evolution of IP Networks

Segment Routing is now a well-accepted evolution path for simplifying IP/MPLS networks and for providing a solution to address the emerging requirements of 5G/IoT and service virtualization. We believe SR-MPLS and SRv6 will be increasingly deployed in service provider, enterprise, and data center networks. However, it is still early days for SRv6, and there is still a lot of work ahead to develop the vendor ecosystem and get to standardized, interoperable implementations of key features and services.

Using SR-TE IGP Flex-Algo in the Multiplanar Backbone design

This whitepaper describes the drivers, use cases, and design of the multiplanar backbone.
Given stringent financial controls, flat CapEx and OpEx budgets, and being asked to do more with the same or less, network operators are limited in their ability to create new services and new revenue streams.
The concept of a multiplanar design, or multiplanar backbone (MPBB), which this document introduces, can be used to deliver the next generation of services and support as well as increase reliability and performance over today’s current network designs.
The MPBB design leverages the flexibility and simplicity of SR-TE IGP Flex-Algo. Read this document to find out how Flex-Algo helps realizing the MPBB goals.

ACG Research Paper: Segment Routing

Service providers and large enterprises face stiff challenges: the network infrastructure and their operations are growing at tremendous pace and becoming complex. IP/MPLS networks have become operation intensive because of their complex implementations. Service providers feel the added pressure of falling revenues and stiff competition by the over-the-top providers as well as the challenge to innovate. These drivers make the network owners think about a transport technology that can provide convergence across layers, domains and offload the complexities in the networks today. One of these technologies is Segment Routing (SR), which has caught the attention of the network planners because of its potential to ...

Flexible Algorithm makes Segment Routing Traffic Engineering even more agile

As more and more Service Providers and Enterprises operate a single network infrastructure to support an ever-increasing number of services, the ability to custom fit transport to application needs is critically important. In that respect, network operators have been exploring Traffic Engineering techniques for some years now but have obviously run into many scaling issues preventing them from having an end-to-end, fine-grained control over the myriad services they offer. We firmly believe Segment Routing Traffic Engineering (SR TE) has changed the game and has become the undisputed solution to deliver Traffic Engineering capabilities at scale. What makes SR Flexible Algorithm a noteworthy addition to SR TE solution?

Simplifying Networks through Segment Routing

The networking industry is going through an incredibly dynamic time of change and opportunity. Global IP traffic will increase nearly threefold over the next five years and 127-fold from 2005 to 2021. The number of devices connected to IP networks by 2021 will be three times higher than the global population. On top of that, the diversity of applications has never been greater, with each having its own set of requirements and hurdles. This unprecedented growth requires Service Providers to transform their networks, and Segment Routing is becoming one of the keys to successfully paving the way to that transformation.

Add a dollop of XTC to your network infrastructure

Google XTC and you find out it was an English rock band formed in 1972 and active till 2006... It probably does not ring a bell to most of you — at least for me, I can’t recall any of their songs. XTC had another connotation in the 1980’s, but that’s not the point here either.


Why I care about Segment Routing

As a WAN guy by chance and opportunity, and a service provider engineer and architect by choice (and also chance and opportunity), segment routing (SR) is one of those wonderful new technologies that keeps rearing its head over and over in recent days – and it’s already playing in the big leagues.

What is Segment Routing?

Do you remember source routing, used in token ring bridging networks? If you're relatively new to networking, you may not know about it. In source routing, the hosts determine the path to take through the network and build a frame header that specifies the forwarding nodes that the frame should pass through as it goes from source to destination.

Bringing Segment Routing and IPv6 together

You may be pretty familiar with Segment Routing and I bet you’re likely tying it to MPLS as the industry at large has been mainly focused on driving awareness and adoption of MPLS Segment Routing. But did you know Segment Routing could work in a native IPv6 environment? Sounds interesting to you?
