Calient, Packetcounter Team on 40G
SAN FRANCISCO -- CALIENT Technologies, Inc., the global leader for Optical Circuit Switching (OCS) technology, and Packetcounter Inc., a new Silicon Valley networking startup, today announced a partnership to deliver a hybrid packet-optical data center network architecture that will allow data center operators to deploy 40 Gbps network capacity at up to seven-times lower cost than current packet-based solutions.
The companies will present the new architecture at the OFC 2014 Exhibition, taking place March 11-13, 2014, at the Moscone Center in San Francisco.
The solution consists of a new hybrid packet-circuit controller currently in development by Packetcounter, together with CALIENTs flagship S320 Optical Circuit Switch. Not only does this new approach offload traffic from packet-based networks very efficiently and cost effectively, it also offers ultra-low path latency of less than 50ns.
The new Packetcounter OCS Controller monitors network traffic between racks in a data center cluster. If a rack is sending a significant amount of traffic to another rack, the controller creates a physical optical circuit from the sender rack through the CALIENT S320 Optical Circuit Switch to the receiver rack, and modifies the routing tables in the sender top-of-rack switch to route traffic over the dedicated circuit.
This is done reactively and transparently so that the servers are unaffected by the change, yet are able to take full advantage of the increased network capacity. Network traffic is not disrupted during the changeover because routes using old circuits are removed before taking down the old circuits, and new circuits are setup before new routes are added.
