Companies such as Oracle are investing in Software Defined Networking (SDN) — turning features that were once hardware into apps or part of the networking layer or running as apps on servers. I've recently written about the problems and promises of SDN and find the …

Broadcom's Ram Velaga on OpenNSL and silicon

One of the reasons Facebook has been driving the Open Compute Project is to break the network switch market out of its long habit of being proprietary on the inside. Broadcom's decision to adopt the Open Network Switch Library (OpenNSL) is a big shift in that space, so The Register talked to Ram Velaga, senior VP of Broadcom's …

Kill queues for fast data centres: MIT boffins

MIT researchers hope to speed up networking inside the data centre with concepts that will look familiar to old networking hacks: they propose a central arbiter for network traffic that picks out a predetermined path before a packet is transmitted. The boffins call the scheme Fastpass, and its other characteristic is that the …

Chinese boffins ginger up Hadoop with OpenFlow funnel

Few doubt that the premise of software-defined-networking (SDN) is a good one: organisations that run a lot of virtual machines and virtual networks can benefit from the flexibility and automation SDN provides.
