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.

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

Because of the global nature of Internet system, it becomes more difficult to centralize the system management and operation. For this reason, the system must be hierarchical such that it is organized into multiple levels with several group loops connected with one another at each level. Therefore, hierarchical routing is commonly used for such a system.

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.

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:

• The distance vector multicast routing protocol is multicast routing protocol that takes the routing decision based upon the source address of the packet.

• This algorithm constructs the routing tree for a network.

• Internet Group Management Protocol is a group management protocol that mainly manages the group membership in a multicast network.

• In a multicast network, multicast routers are used to route packets to all the computers that are having membership of a particular group.

• This protocol was developed by Rick Adams in 1984.

• The initial purpose of this protocol was to connect Sun workstation to the Internet over a dial-up line using modem.

In Routing Protocol, Routing is the process of selecting paths in a network along which to send data on physical traffic. In different network operating system the network layer perform the function of protocol routing. In TCP/IP the IP protocol is the ability to form connections between different physical networks with the help of a Routing Protocol.

The distance-vector routing Protocol is a type of algorithm used by routing protocols to discover routes on an interconnected network. The primary distance-vector routing protocol algorithm is the Bellman-Ford algorithm. Another type of routing  protocol algorithm is the link-state approach.

HDLC - Short for High-level Data Link Control, a transmission protocol used at the data link layer (layer 2) of the OSI seven layer model for data communications. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors. HDLC is an ISO standard developed from the Synchronous Data Link Control (SDLC) standard proposed by IBM in the 1970's. HDLC NRM (also known as SDLC) .

The SDLC or the Synchronous Data Link Control was first developed by IBM in 1975. It was modified by ISO and was named HDLC. Thus SDLC is a subset of HDLC and includes several minor additional features.
