We assumed that the underlying networks over which the IP datagrams are moving are either LANs or point-to-point WANs. In this section, we want to see how an IP datagram is moving through a switched WAN such as an ATM. We will...

The error detection method used by most TCP/IP protocols is called the checksum. The checksum protects against the corruption that may occur during the transmission of a packet. It is redundant information added to the...
The Internet Protocol (IP) is the transmission mechanism used by the TCP/IP protocols at the network layer. Figure shows the position of IP in the suite. IP is an unreliable and connectionless datagram protocol a best effort...
Delivery The network layer supervises the handling of the packets by the underlying physical networks. We define this handling as the delivery of a packet. The delivery of a packet to its final destination is accomplished using...
Management development programs help in acquiring and developing managerial skill and knowledge. A Varity of methods of management development have come into prominence these days. Different types of techniques are used to...
The body is organized from its smallest element, the cell, to the collection of systems, with all its interrelated parts. Cells The entire body is made of cells that vary in size, shape, and function, but all cells have one thing...
Executive development is more future oriented. It is more concerned with education than is employee training. In today’s competitive environment, an organization has to be concerned about the development of supervisors, middle...
As we discussed before, the IP addresses were originally designed with two levels of addressing. To reach a host on the Internet, we must first reach the network and then the host. It soon became clear that we need more than two...
The training design process refers to a systematic approach for developing training programs. It includes the seven steps in this process. Training is one of the most profitable investments an organization can make. No matter...
Two level addressing : The whole purpose of IPv4 addressing is to define a destination for an Internet packet (at the network layer). When classful addressing was designed, it was assumed that the whole Internet is divided into...
