US 2013/0086295 A1 · COMMUNICATION CONTROL SYSTEM, SWITCHING NODE, COMMUNICATION CONTROL METHOD AND COMMUNICATION CONTROL PROGRAM

Abstract

In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

Dependent claims

A communication control system comprising:

a switching node configured to execute conventional network service;
and
a control server configured to execute extended network service,
wherein said switching node comprises:
a first internal bus used for forwarding a frame for internal processing;
a second internal bus for forwarding a frame for external transmission;
and
a forwarding engine configured to operate depending on a type of an input frame, to forward a frame regarding said conventional network service to said first internal bus for internal processing in said switching node, and to forward a frame regarding said extended network service to said second internal bus for utilizing said control server.
