IEEE chaps propose QoS for SDN across the public internet

Software-defined networking (SDN) is fine in the data centre, but rubbish across multi-domain WANs, something a group of IEEE engineers wants to solve. Their proposal, on Arxiv, is to copy the cloud notions of abstraction and orchestration into Internet connections. Sucking nourishment out of the academic prose, the IEEE …

Microsoft gets storage QoS and software-defined storage religion

Microsoft is starting to make a lot of noise about software-defined storage and the need for storage quality of service. The company's Cambridge UK lab has just released Microsoft Research Storage Toolkit, a tool said to enable “effective and accessible research in Software Defined Storage by adding I/O classification functions …

Accedian goes hybrid NFV in carrier QoS product

Rather than pull out all the stops on network function virtualisation (NFV), telcos would like to stage their implementations one piece at a time, according to Canadian vendor Accedian Networks. That's the rationale behind the approach the company announced late last week, in which it wants to offer an enterprise-to-data-centre …

Sprint sprints away from no-throttle policy – punishes 'unlimited' network hoggers

Sprint has confirmed plans to once again throttle data usage of customers who go over a 23GB limit each month. The company, which is the fourth largest mobile carrier in the US with nearly 58 million subscribers on its books, said that it was "unfair" to allow such behaviour to continue unchallenged, given that 97 per cent of …

Software-defined what? Look at our glorious ASICs says Cisco

Cisco's taking up arms against a sea of white-box vendors, touting US$150 million worth of silicon in the form of an ASIC. What's interesting, however, is that the pitch – in this blog post – isn't about what's coming this year or next. The slab of silicon, which the Borg is calling the “Unified Access Dataplane” (UADP), …

Ten things you always wanted to know about IP Voice

When I was a contractor building IT architectures, it was common to find that people had a rather old phone system and were looking to move to something newer.

Flash is fallible. But you'd rather have an AFA than spinning rust

We tend to think of flash as a solid-state disk – like spinning rust, only more expensive, consuming less power, and much, much faster. And yes, it is true that you can use it like that, but there is a lot more that flash can offer if you start to take into consideration what makes flash different in the first place. Simply …

Storage consolidation looks great on paper. Direct-attached storage is notorious for its inefficiency, with some arrays being just 40 per cent occupied or even less.
