Abstract Abstract
Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode,
and Ethernet) can be "emulated" over an MPLS backbone by and Ethernet) can be "emulated" over an MPLS backbone by
encapsulating the Layer 2 Protocol Data Units (PDU) and then encapsulating the Layer 2 Protocol Data Units (PDU) and then
transmitting them over "pseudowires". It is also possible to use transmitting them over "pseudowires". It is also possible to use
pseudowires to provide low-rate Time Division Multiplexed and pseudowires to provide low-rate Time Division Multiplexed and
