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
The companies will present the new architecture at the OFC 2014
Exhibition, taking place March 11-13, 2014, at the Moscone Center in San
The solution consists of a new hybrid packet-circuit controller
currently in development by Packetcounter, together with CALIENT's
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.
How the Solution Works
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
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
"We're very excited about our partnership with Packetcounter," said
Daniel Tardent, CALIENT's Vice President of Marketing. "The hybrid
packet-optical network offers huge economic advantages for data centers
but until now it has only been realistic to deploy for the very largest
cloud data centers with significant internal development capabilities.
The new Packetcounter OCS Controller will support new 'out-of-box'
solutions that will allow these economic advantages to be enjoyed by a
much larger range of data centers."
"The Packetcounter founders have dedicated a number of years to
demonstrating the benefits of hybrid packet-optical networks in research
projects," said Nathan Farrington, CEO of Packetcounter. "The explosion
of 40 Gbps traffic in data centers was the signal to us that the market
is ready for a commercial solution. CALIENT has the highest port-count
optical circuit switch in the data center industry so choosing to
partner with them was a clear win-win for both companies."
CALIENT's S320 Optical Circuit Switch is shipping in volume today. The
Packetcounter OCS Controller is planned to be available for proof of
concept deployments in Q2 2014.
The combined CALIENT-Packetcounter solution will be presented in booth
302 at OFC (March 11-13, 2014, in San Francisco, Calif.). OFC is the
largest global conference and exposition for optical communications and
networking professionals. For more information, visit http://www.ofcconference.org/.
About CALIENT Technologies
CALIENT Technologies is the global leader in pure photonic Optical
Circuit Switching with systems that enable dynamic optical layer
optimization in next generation datacenters and software defined
networks. CALIENT's 3D MEMS switches allow data center operators to
cost-effectively deploy 40 Gbps services at up to seven-times lower cost
than conventional packet-based solutions. The company designs and
fabricates its systems using state of the art MEMS equipment in its own
fabrication facility located at its corporate headquarters in Santa
Barbara, California. For more information, visit us at http://www.calient.net,

Packetcounter, Inc. is a computer network software company founded by
two researchers from Amin Vahdat's team from UC San Diego who pioneered
the field of optically circuit-switched (OCS) data center networks.
Packetcounter's OCS controller provides the missing control plane needed
by data center operators wishing to offload traffic from more expensive
"big iron" packet switches onto low-cost and low-power OCS switches. The
company is located in Cupertino, California. For more information,
