System and method for interconnecting physical channels

摘要

A system and method for interconnecting physical channels is provided. The system includes a port containing an optical receiver, a port control module, a route determination module, and a connectivity module. The port control module is operably connected to a first physical channel to receive a Fiber Channel frame comprising data and a data header. The route determination module selects a route between the port control module and the second physical channel according to the data header. The connectivity module is operably connected to the port control module and to the route determination module. The connectivity apparatus may switch frames between the port control module and the second physical channel under control of the route determination module in order to transfer Fiber Channel frames to the second physical channel.

1. An interconnect system for interconnecting a first physical channel and a second physical channel, the interconnect system comprising:
a port operably connected to the first physical channel, the port comprising an optical receiver operable to receive a Fibre Channel frame comprising data and a data header; a port control module coupled to the port and operable to read the data header; a route determination module for determining how to route the Fibre Channel frame according to the data header; and a connectivity module coupled to the port control module and to the route determination module, the connectivity module being operable to route the data in the Fibre Channel frame as determined by the route determination module, whereby data in the Fibre Channel frame are transferred to the second physical channel, wherein the connectivity module is operably connected to a FIFO to receive data from the port, wherein the port control module guards against a receive FIFO overrun condition.
