Microsoft researchers are developing ServerSwitch, a programmable, low-cost switching chip that could supplement cloud and other network-based services. ServerSwitch integrates a programmable application-specific integrated circuit switching chip with a programmable multicore commodity server and control software that can handle data center network traffic more efficiently, says Microsoft Asia researcher Guohan Lu.

He says that in the future ServerSwitch could be used to help technologies such as OpenFlow, an open source switching specification. Both OpenFlow and ServerSwitch are designed to lead to a more programmable networking platform, according to the researchers.

"By leveraging the low latency of its PCI-E interface and efficient server software design, we can implement software defined signaling and congestion control in the server central processing unit (CPU) with low CPU overhead," Lu says.
