Abstract
A virtual segmentation system for use with a routing switch processor and a method of operating the same. In one embodiment, the virtual segmentation system includes a protocol data unit receiver subsystem configured to receive at least a portion of a protocol data unit and assemble the protocol data unit. The virtual segmentation system further includes a virtual segmentation subsystem that is associated with the protocol data unit receiver subsystem and is configured to perform virtual segmentation on the protocol data unit.
Claims7
A router, comprising:
- a physical interface coupled to a first network;
- a fabric interface controller coupled to a fabric network;
- a fast pattern processor that receives packets of a protocol data unit from said physical interface, performs pattern recognition and classification on said packets and said protocol data unit;
- and
- a routing switch processor that receives said protocol data unit from said fast pattern processor and transmits via said fabric interface controller, said routing switch processor having a virtual segmentation system, including:
- a protocol data unit receiver subsystem that receives at least a portion of said protocol data unit and assembles said protocol data unit;
- and
- a virtual segmentation subsystem, associated with said protocol data unit receiver subsystem, that performs virtual segmentation on said protocol data unit.
