Update: CALIENT Software-Defined Hybrid Packet-Optical Datacenter Networking Architecture

350

Published on

In the hybrid packet-optical circuit switch network, optical circuit switches (or photonic switches) are installed in a data center to augment packet-based switching to create a hybrid solution. Network management scripts or software-defined networking (SDN) are used to redirect data flows from one network to another. The flow detection and redirection can be based on a number of factors including scheduled events such as virtual machine or data migrations, or real time events such as a network analytic requesting more bandwidth.

  • What we show here is the well known multi-layer SDN model with application, control, and infrastructure layers.The important point here is that the packet and optical circuit switches can all coexist together in the infrastructure layer with coordinated control from the upper layers.
