摘要： A Residential Ethernet switching apparatus for performing time slot switching includes an input unit for receiving frames as input, and a parser for parsing the received frames into asynchronous Ethernet frames (AsyncE frames) and Residential Ethernet frames (ResE frames). An AsyncE switching processor performs a switching operation for an AsyncE frame parsed by the parser. A ResE switching processor performs, according to positions of time slots included in a ResE frame parsed, a virtual MAC (VMAC) processing for the ResE frame The ResE switching processor also performs a switching operation based on a result of the VMAC processing. A multiplexer multiplexes the AsyncE frame switched by the AsyncE switching processor, and the ResE frame switched by the ResE switching processor, for output.
