In TCP communications, not only TCP but also UDP (User Datagram Protocol) can meet the functional requirements defined in the transport layer. Unlike TCP, UDP is a connectionless type protocol in which the sending terminal does not check whether data has been received by receiving terminal. In other words, it is a less reliable protocol. However, this protocol makes it possible to omit a variety of processes thus reducing the load on the CPU.

In a mesh network, the routing of packets is part of a complex algorithm, by the distribution of decisions, which are both space and time. A node should know the status of all the other nodes before deciding where to send a packet, which is impossible to achieve.

IP addresses are assigned independently of the hardware addresses of the machines. To send a datagram on the Internet, the network software must convert the IP address into a physical address, used to transmit the frame.

These are OSPF, IS-IS (Intermediate System to Intermediate System Intra-Domain Routing Exchange Protocol).

The problem encountered while performing local routing may be summarized as follows:

The major objective of network design is to select the network service and to determine the transmission speed for the system. Following are the typical examples of network using WAN and network services:

Routing refers to the process of selecting the shortest and the most reliable path intelligently over which to send data to its ultimate destination. IP routing protocol makes the distinction between hosts and gateways. A host is the end system to which data is ultimately deliverable. An IP gateway, on the other hand, is the router that accomplishes the act of routing data between two networks. A router can be a specialized device supporting multiple interfaces connected to a different network or a computer multiple interfaces (commonly called a multihomed host) with routing services running in that computer.

For routing in a network having two or more routers, routing tables are used to determine the destination to which a packet is to be forwarded. If two or m9re routes are available, the route that requires the least possible cost (link cost) should be selected so that the packet can be sent to the destination more quickly and more reliably. Cost can be generally considered as the number of routers via which the packet is to be sent. If changes are made to this network configuration, there are two methods to update the contents of routing tables, which will be described next.

A parameter that controls how long a network switch or ROUTER will store learned IP addresses in its address table before discarding them for new ones.

The NHRP (Next Hop Resolution Protocol) comes from the Internet world and is described in RFC 1932. It allows to search the ATM corresponding to an IP address in an NBMA network of several DSL. Specifically, NHRP allows the resolution of an IP address of a workstation on a remote DSL NBMA address of a network (ATM address, frame relay, etc.).
