SRv6 - Building Next-Gen Programmable Network Infrastructure

Segment routing is not a new concept in the networking industry and it has gained great popularity among service providers around the globe. While service providers are adopting it for the multiprotocol label switching (MPLS) data plane that is deployed extensively in existing networks, there is an increased interest to use segment routing with the IPv6 data plane for network programming (SRv6 network programming). There are many use cases that can benefit from the SRv6 network programming concept. Today, 5G is the main driver for fast-paced development of SRv6 standards to simplify the user plane and network plane. With Ixia’s IxNetwork SRv6 solution, customers can simulate SRv6 networks with many nodes to validate device under test (DUT) functions in different roles (ingress node, intermediate node, and egress node) and assess the performance for both control- and data-plane...

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 ...

Celebrating Segment Routing’s 5th Birthday

With the explosive growth of network traffic, there is more pressure than ever on the network to operate with simplicity, speed, scale and resiliency. Since the emergence of Segment Routing (SR) five years ago, more and more customers have turned to this technology to help address the challenges of digitization and to accelerate the network transformation necessary to meet those challenges.

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?

Packet Pushers podcast on SRv6

Today on the Packet Pushers Weekly Show we talk about control. Imagine being able to control every flow in your data center in a granular way, and not just based on the best path your routing protocol decides or the random hashing your ECMP comes up with. How do you get beyond the forwarding we’re used to? By manipulating flows with modern tools. One such tool is IPv6 segment routing (SRv6). Cisco, along with network architects from Bell Canada and LinkedIn, discuss just how IPv6 Segment Routing makes the network programmable in this sponsored episode.

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.

Segment Routing IPv6 — Interoperability demo is already there!

Who would have bet on a SRv6 interoperability demonstration at SIGCOMM 2017 conference this summer? Very few of us actually… For those who are not familiar with the SIGCOMM 2017 conference, this is a highly respected conference where key networking innovations and orientations are being discussed every year by leading vendors, major web and service providers, and academic researchers.

Segment Routing — Ready to Surf the v6 Wave?

Segment Routing has crossed the chasm — "Early Adopters" have already embraced it, and now the "Early Majority" is adopting it. Interestingly, at the very same time the industry is surfing the Segment Routing MPLS wave, the next wave is already coming in and will even be more disruptive to the way you design and engineer your network infrastructure – this is the Segment Routing IPv6 (SRv6) wave.

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?
