The traditional
approach to packet switching (X.25), used in-band signaling, and includes
end-to-end and well as per-hop flow control and error control. This approach
results in considerable overhead. Frame relay is a packet modetrans mission
service that exploits characteristics of modern networks by
Qus:2
List and explain the advantages of virtual path connection (VPC)
Answer:
The
advantages of virtual path connection (VPC):
A virtual path
connection (VPC) is a bunch of VCCs share the same endpoints where all the
cells flowing over all the VCCs in a single VPC are switched together. Grouping
connections that share a common path over the network reduces the control
costs. There are many advantages of VPC some of
