Datagram ApproachA packet-switching technology in which a packet exists is called a datagram. It is treated as a separate entity. Each packet includes data about the destination, and the switch helps this data forward the packet to the right destination. It is also known as connectionless switching.Virtual CircuitVirtual Circuit is ... Read More

Congestion causes choking of the communication channel. When too many packets are displayed in a part of the subnet, the subnet's performance degrades. Hence, the network's communication channel is called congested if packets are traversing the path experience primarily over the path propagation delay.It is known as heavily congested when ...

Each router on the network supports a routing table in memory that may be simple or complex. In the simplest form, the table consists of pairs of IP addresses.When the originating station involves that the intended destination is directly reachable, the frame is sent immediately to the frame's destination IP ...

Connection-Oriented ServicesIn a connection-oriented service, each packet is related to a source/destination connection. These packets are routed along a similar path, known as a virtual circuit. Thus, it provides an end-to-end connection to the client for reliable data transfer.It delivers information in order without duplication or missing information. It does ... Read More

The B-ISDN (broadband integrated services digital network) is a virtual circuit-switched network that can use high-speed packet switching services. The B-ISDN will use a flexible multiplexing format called ATM (asynchronous transfer mode).B-ISDN services are classified into interactive and distribution services. Interactive services contain the bidirectional flow of user information between ... Read More

A TCP connection is a full-duplex connection. To understand the connection release, we can consider them to be a pair of simplex connections. We can then imagine that each simplex connection is being released independently. Releasing a TCP connection is symmetric. Either port can send a TCP segment with the ... Read More
