Abstract
In one embodiment, an apparatus includes an intake buffer module and a flow control module configured to define an available bits indicator, the available bits indicator representing a number of unallocated bits within the intake buffer module. The apparatus further includes a transceiver module configured to transmit, to a peripheral device, a credit update frame based at least in part on the available bits indicator. The transceiver module can be configured to receive a Fiber Channel over Ethernet (FCoE) frame from the peripheral device, a size of the FCoE frame being less than or equal to the number of unallocated bits. The apparatus can further include a switch fabric interface module operatively coupled to a plurality of switch fabric devices that define at least a portion of a switch fabric. The switch fabric interface module can be configured to define at least one cell based at least in part on the FCoE frame and further configured to transmit the at least one cell to at least one switch fabric device from the plurality of switch fabric devices.
