MPoFR configuration example
Network requirements
As shown in Figure 37, the ATM backbone network uses FR network as the access network to
support transmitting traffic of multiple services. A single virtual circuit of an FR link can transport
multiple kinds of service data.
The bandwidth of Router A Serial2/0 is 64 kbps. Host A sends data traffic stream 1 to Host C, Host B
sends data traffic stream 2 to Host D, and a voice service stream exists between Router A and
Telephone A.
The bandwidth of Router B Serial2/0 is 64 kbps. Host C sends data traffic stream 3 to Host A, Host D
sends data traffic stream 4 to Host B, and a voice service stream exists between Router B and
Telephone B.
To ensure voice quality, fragment the data packets to reduce voice jitter caused by transmission
delay. MPoFR is used here, and MP is used to fragment data packets.
