Frames of data of arbitrary length and protocol are received by a switch from a transmitter and encapsulated with a standardized header and trailer to produce a number of small bursts which are transmitted on to a high speed bus. The standardized header provides, among other things, a way in which reassembly of the bursts at a receiver occurs. The trailer typically contains a cyclic redundancy check to ensure data integrity. The process is protocol-independent, i.e., the transmitter and receiver of the frames may be of similar or dissimilar protocols, such as Ethernet, Fiber Distributed Data Interface (FDDI), and Asynchronous Transfer Mode (ATM). |
