Network management is the procedure of administering, managing and working a data network using a network management system. Current network management systems use software and hardware to constantly collect and analyse data and push out configuration changes for increasing performance, reliability, and security.It involves configuring monitoring and possibly reconfiguring components ...

ATM transfers data in fixed-size units are known as cells. Each cell includes 53 octets or bytes, as shown in the figure. The first 5 bytes contain cell-header data, and the remaining 48 include the payload (user information).Small, fixed-length cells are well appropriated to transfer voice and video traffic due ...

When data is shared from one computer to another computer, the system does not protect whether the information received by the computer is actually to the data transmitted by another computer. An error is when the message received at the receiver end is not interchangeable with the message sent.Types of ... Read More

Data Link Layer is the second layer in the OSI reference model. It represents creating a shared transmission medium and frequent transmission of the data frame in a computer transmission setting.It obtains a natural flow of items for the physical layer at the sender device. The primary stream of data ... Read More

Circuit SwitchingIn this approach, there is a dedicated route between sender and receiver. Before the link is determined in the circuit switching approach, the dedicated route will continue until the connection is eliminated.Message SwitchingMessage Switching is an approach in which a message is sent as a whole unit and routed ...

Packet switching merges the benefit of the message and circuit switching. Long messages are divided into smaller units known as packets.A question appears as to how the network will manage this flow of packets as it tries to path them through the network and transfer them to the planned designation. ...

In message switching, the sending device joins the destination location to the communication and develops it to the network. The message is then generated by the web from one node to the other node, because it arrives at the predetermined destination.Each switching hub gets a message, stores it momentarily and ... Read More
