CALIENT Software Defined Hybrid Packet-Optical Datacenter Network
CALIENT Software Defined Hybrid Packet-Optical Datacenter Network allows efficient optical topologies to be built on demand, optimizing access to compute and storage nodes to achieve maximum utilization of these critical resources.
With the addition of traffic analysis and traffic engineering capabilities, the controller supports the full hybrid packet-optical network, in which the optical layer is reconfigured dynamically to create optical “express” paths that offload highly persistent traffic flows from the L2/3 packet network.
This means that applications and traffic pattern analysis algorithms will be able to drive the optical layer topology to achieve the highest levels of throughput and efficiency, thereby relieving the layer 2/3 network to efficiently deliver the more transient traffic. Pure optical circuit switched networks also offer tremendous cost savings – typically 80 percent less expensive than L2/3 solutions at 100Gbps.
In the event that a large persistent data flow opens up between specific TORS, the packet network may become a bottleneck in the performance of the network, or it may simply add too much latency for the application making use of the connection. In these cases a direct optical path can be opened up between the TORS through the OCS fabric. This allows unconstrained data flow between the TOR uplinks with the absolute lowest latency possible.
