Abstract
A protocol translation hardware assist for resolving protocol incompatibilities in a multi-protocol switching environment. Discrete information units are transferred seamlessly from inputs to disparate protocol outputs by writing inbound discrete information units into selected address spaces in allocated buffers in a transfer queue in a manner which accounts for protocol format differences while allowing for straightforward dequeueing. The hardware assist fragments inbound discrete information units into multiple outbound units and creates offsets indicated by destination protocol requirements. A bypass check may be implemented to avoid subjecting to the fragmentation inquiry discrete information units for which it can be inferred a priori that fragmentation is not required.
