    Abstract: A way to assign flexible prefixes to Switches in Fibre Channel Fabrics while using the currently defined FC_ID address space. This allows end devices in different Fibre Channel Fabrics to communicate with one another, without requiring modifications to existing end devices, nor to perform Network Address Translation between Fabrics. The existing address space for each Switch includes a dynamically configurable number of host bits sufficient to address all the end devices coupled to the Switch and the Switch itself. The remaining bits, called the Switch prefix, are used to identify the Switch in the switching Fabric. In an alternative embodiment, the Switch prefix bits may be further configured into a first sub-set of bits used to identify a specific Fabric (Fabric prefix) and a second sub-set of bits used to identify the Switch in the Fabric (Switch_ID).
