Colt Fast-Tracks the Delivery of New Services with Cisco Segment Routing and Ethernet VPN

Cisco and Colt Technology Services announced today that they have successfully achieved a key milestone in upgrading Colt's pan-European, U.S. and Asian packet network. This lays the foundation for the Colt IQ Network to deliver further differentiated, high-bandwidth connectivity solutions. Colt's next-generation packet network uses end-to-end segment routing technology to simplify and automate network operation and significantly reduce operating costs. With the quality, speed, capacity and flexibility to meet application-specific service quality requirements, Colt’s customers will benefit from an infrastructure designed for enabling digital businesses.

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.

Bell Canada implements Cisco Segment Routing

Over the past few weeks, Bell Canada has successfully rolled out Segment Routing in its next-generation core network, marking a milestone as the first Canadian carrier to actively use this innovative technology for network automation and software-defined networking (SDN) capabilities.

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.

Barefoot Networks and Cisco showcase SRv6 interoperability at SIGCOMM 2017

At SIGCOMM 2017, Cisco Systems and Barefoot Networks showcased SRv6 interoperability of SRv6 VPN with traffic engineering and service chaining. The demonstration included three Cisco hardware implementations (Fretta, ASR9k and ASR1k); open source implementations in the Linux Kernel and FD.io VPP; and Barefoot's Tofino switch.

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?

Supercharge Your Network with Segment Routing Innovations!

2016 is clearly an inflection point in Segment Routing adoption. Enterprise and Service Providers have tested and validated the technology and are ready to roll out the technology in live networks. Customers now fully understand the benefits of the technology - it's all about bringing simplicity and scalability to the network. No RSVP, no midpoint state, no tunnel to configure!
