ABSTRACT:
A Fiber Channel router used to join fabrics. EX_ports are used to connect to the fabrics. The EX_port joins the fabric but the router will not merge into the fabric. Ports in the Fiber Channel router can be in a fabric, but other ports can be connected to other fabrics. Fiber Channel routers can be interconnected using a backbone fabric. Global, interfabric and encapsulation headers are developed to allow routing by conventional Fiber Channel switch devices in the backbone fabric and simplify Fiber Channel router routing. Phantom domains and devices must be developed for each of the fabrics being interconnected. Front phantom domains are present at each port directly connected to a fabric. Each of these is then connected to at least one translate phantom domain. Zoning is accomplished by use of a special LSAN zoning naming convention. This allows each administrator to independently define devices are accessible.
