Abstract
A routing module applies a plurality of routing rules simultaneously to determine routing for a Fibre Channel frame. Each rule independently determines whether the rule applies to the frame as well as a routing result for the frame. The routing result includes a port address, a zoning indicator, and a priority designation that can be used to route the frame over a virtual channel in an interswitch link. A selector chooses between the results returned by the rules. A component receives routing results specifying an ISL group and selects a physical ISL for the frame. An in-band priority determined by the content of the frame header can also be used in place of the priority designation in the routing result.
