Q2. What are the two approaches to packet-switching?
Ans. The two approaches to packet-switching are-
a) Datagram Approach: Connectionless Service
- When the Internet began, the organization layer was intended to give a
connectionless assistance.
- The organization layer convention treats every bundle autonomously.
- The parcels in a message could possibly venture to every part of a similar way
to their objective.
- The switches in this sort of organization are called switches.
- Each parcel is steered dependent on the data contained in its header.
- In a connectionless bundle exchanged organization, the sending choice is based
on the objective location of the bundle.
- In the datagram approach, the forwarding decision is based on the destination
address of the packet.
