need to do 4 problems related to computer networks on
2)Consider a virtual-circuit network. Suppose the VC number is a 4-bit field.
a, What is the maximum number of virtual circuits that can be carried over a link?
b, Suppose that different VC numbers are permitted in each link along a VC’s path.
During connection setup, after an end-to-end path is determined, describe how the links
can choose their VC numbers and configure their forwarding tables in a decentralized
manner, without reliance on a central node.
3)Consider sending a 4000-byte datagram into a link that has an MTU of 500 bytes.
Suppose the original datagram is stamped with the identification number 526. How many
fragments are generated? What are their characteristics? (Assume IPv4 is used so the IP
header is 20 bytes in length)
