Below, China's Centec showed a new reference design for its Golden Gate switch supporting up to 48 10Gb/s ports and four 100G ports. The company is trying to differentiate its chip by supporting a number of emerging SDN standards including SAI, ONIE and 32,000 Geneve tunnels with routing.

So far most of Centec's customers are companies among the dozens of second- and third-tier comms OEMs in China. However it has design wins overseas and has its sights sets on top tier OEMs such as Huawei and ZTE in China and beyond.

New languages, evolving silicon

SDN

Nabil Damouny

Nabil Damouny (above), senior director of business development at Netronome, shows the company's NFP4000, a 48-core packet processor coming next year aimed to lead the company's move beyond appliances into server accelerator cards.

Netronome's high-end NFP6000 is a 216-core version sampling now. The chip was used last week to demo the emerging P4 language, geared for programming packet processor operations in the network data plane. The language, which uses a two-step compiler, could be ready for use in production networks as early as next year, he estimated.

Separately, AT&T released Yang, a data modelling language for software-defined networks. The Open Daylight group will use Yang as part of its SDN controller, said AT&T's Donovon.

Below, Freescale demoed its T4240 QorIQ PowerPC-based chip handling policy-based routing for 40Gb/s data flows running its VortiQa software that supports Openflow agents and OpenStack. Freescale will show Layerscape, its ARM-based version, running at its annual event in Austin next week. It will not have optimised performance figures for Layerscape until later this year.
