Abstract
There is provided a protocol separator having a processor with an input port and output ports, and data links connected to the input port and to the output ports, with the data link to the input port carrying packetized data including packets of different protocols, the data link to one of the output ports carrying packets of a first protocol removed from the stream by the processor, and with the data link connected to the other output port carrying the remainder of the packets which were delivered to the input port. The protocol separator operates by determining at least part of a byte in the selected protocol packets which characterizes that protocol, monitoring the stream to detect the occurrence of that part of a byte, and diverting packets containing the part of a byte from the stream to one of the outputs. The remainder of the stream is fed to the second output.
