Software-defined networking is coming to the datacenter despite lingering concerns about the maturity of the technology, according to an upbeat forecast that predicts SDN deployments will begin in 2015. Infonetics Research forecasts that 87 percent of North American-based enterprises surveyed intend to deploy SDN in their datacenters and campus LANs by 2016. “The leaders in the SDN market serving ...

After several days of presentations and a unanimous vote of 61 to zero in favor, the members of the IEEE have decided to back an effort to develop 25 Gb/sec Ethernet standards for servers and switching. The formation of the study group is the first step in a process that will almost certainly culminate in a new and more ...

Big Switch Networks, a networking startup that was spun out of the Stanford University labs that created the OpenFlow protocol that underpins a lot of software-defined networking stacks, is rolling out its Big Cloud Fabric Controller. The software is the culmination of four years of work and fulfils its founders’ goals of creating a controller that can span both ...

Data scientists from MIT and Facebook have proposed a centralized datacenter network that chucks the traditional Internet architecture used for packet transmission and path selection, replacing it with a centralized “arbiter” of data transmission that would decide when and along what path to transmit packets. The centralized “zero-queue” data network architecture dubbed Fastpass blends two fast algorithms. The first ...

The emergence of big data, storage, and streaming media applications that have bursty behavior on the network and the prevalence of 10 Gb/sec network adapters on servers is choking the uplinks on top of rack switches. Switch makers are being pushed to offer more uplink bandwidth and much fatter packet buffers, and Arista Networks is jumping out ahead of ...

Having announced that it was joining the OpenDaylight Project a month ago, Extreme Networks has come out with a software-defined networking strategy that will heavily leverage that open source project and that will also make use of the many assets developed by itself and Enterasys, which it acquired last September for $180 million. That acquisition essentially doubled the size ...

Unhappy with the cost per gigabit of bandwidth with current Ethernet switches and adapters, two of the cloud computing giants – Google and Microsoft – have teamed up with two switch chip providers – Broadcom and Mellanox Technologies – and one upstart switch maker – Arista Networks – to create a specification for Ethernet speeds that are different from ...

Cloud deployments depend on many network services such as monitoring, VPN services, advanced firewalling and intrusion prevention, load balancing, and traditional security and optimization policies. If we consider a modern cloud data center that supports potentially hundreds of thousands of hosts, scaling and automating these network services creates the most challenging task for the cloud operator. Fortunately, server virtualization ...

Analog chip developer Avago Technologies continued its foray into the storage market and possible the server market with the acquisition of PLX Technology in a cash deal valued at about $309 million. Singapore-based Avago, which has offices in Silicon Valley, also specializes in analog devices used for enterprise storage. It said PLX’s PCI Express products would complement its server-storage ...

InfiniBand network equipment supplier Mellanox Technologies had been hinting that it would be able to get its first 100 Gb/sec products out the door perhaps in late 2014 or in early 2015, and it turns out that this will happen sooner rather than later. The timing is not accidental, but rather precise, and specifically aims to get the next ...
