SDN software-defined networking

Google's software-defined network – and its significance – both just accelerated

Google last week announced that it has started using version 2.1 of its Andromeda software-defined networking stack. Why are we bothering to report that? A couple of reasons. First, it's fast. Google says it “reduces network latency between Compute Engine VMs by 40% over Andromeda 2.0 and by nearly a factor of eight since we …

Networking vendors are good for free lunches, hopeless for networks

No middle ground, no compromise: VMware blocks Cisco's SDN play

VMware's recent decision to block third-party virtual switches on its platform could put a serious crimp in, among others, Cisco's plans for Software-Defined Networking (SDN). What does this move mean for customers who don't buy into VMware's NSX vision, but prefer the more hardware-centric SDN exemplified by Cisco's ACI? To …

Juniper emits heavy duty photonic interconnect with a cloudy tinge

In January 2016, Juniper Networks swallowed BTI Systems with the aim of bringing software defined network approaches to the optical sphere. One of the fruits of that acquisition has now landed, with the company announcing its Open Cloud Interconnect. Juniper says the new OCI is aimed at inter-data centre connections, with high …

For telcos and enterprise vendors, MWC 2017 will be an Edge/Fog/SDN/NFV-fest

Mobile World Congress kicks off next week in Barcelona and, as ever, is two shows in one. Gadget-lovers get to go “squee!” about new handsets and the fun they'll have with them. And in the fun and important part of the conference, telco wonks discuss the plumbing that makes the “squee!” possible. And this year the fun and …

Bare metal switches racked up a whole $23m of sales in H1 2016

Bare metal switches are mostly still in lab deployments, it seems: according to analyst IHS Markit, sales of branded bare metal switches hit US$23m. For perspective, a giant like Cisco turns over close to $8bn in switch revenue in a half-year. IHS Markit put the first half of 2016 as worth about 125 per cent more than for the …

Microsoft adds SDN automation to System Center's Virty Manager

Microsoft's J.C. Hornbeck has valiantly tried to announce VMM SDN Express for Microsoft System Center VMM: a bundle of automation scripts covering SDN stack deployment; setup inputs; and a dummy parameters file.

YANG: Coming soon to a router near you

It's about time the world had one: a proposal to pull the world of router configuration into the warm embrace of the popular YANG protocol. Reading the RFCs so you don't have to, this one caught the Vulture South eye, because given the scale of networks some sysadmins have to work with, it's the start of something big. Since …

Chinese giants give world another SDN and NFV platform

If you didn't think the world needed another Software Defined Networking (SDN) project, bad luck: you've got one anyway: it's called Open-O and hopes to put SDN and Network Function Virtualisation (NFV) in the same yoke. If that sounds familiar, it's because AT&T also wants to lead the open source world into a combination SDN/ …

OpenFlow controller design killing SDN, say network boffins

OpenFlow's architecture is inefficient, and caps performance while sucking unnecessary power. That's the conclusion of a bunch of Comp. Sci boffins from researchers at Australian brain box Data61 and Sydney University, who assessed four major OpenFlow controllers – NOX, Maestro, Floodlight and Beacon. Their paper is at Arxiv …

Boffins bash better brains into OpenFlow

One of the pitch points of open white-box networking is that it makes Ethernet switches extensible – something exploited by some packet boffins to build what they think is a better way to skin the network monitoring cat. The researchers, from Brown University, are trying to overcome the mismatch between the limitations of old- …
