What is a routing protocol?

The routing protocol is a means by which the computer network is able to efficiently control operation through a device called a router. Any such protocol is essentially an algorithm designed to prevent and repair the loops, collect information about the network topology and distribute this information to other routers, and eventually choose to operate paths. Some of these protocols process operation inside the network and direct it to other routers in the controlled network. When communication needs to enter or leave a specific network, it is directed by another type of routing protocol that monitors the traffic on the edge or border of the network.

When a routing protocol is used on the inside of the network, it is referred to as the Inner Gate (IGP) protocol. Using the same routing protocol together form a routing domain. Subsequently, any number of routing domains together form a net that contains an autonomous system (AS). Here, inside of, protocols fall into two primary categories, protokol for a connection or protocol based on a vector.

with a link for reference-State, the routers speaks together to map the entire network, assess the state of the connection between them, and then calculate the best possible ways that can do the traffic to do. This method is useful in determining which paths can have faster connection speed than other paths and when detecting the shortest path. These types of routing protocol are very fast to converge each other and update their network knowledge when a new router is added or one goes outside the line.

The

Vector Vector Protocol is delivered in two flavors: the vector of the distance vector and the vector of the road, where the latter is the first one. Methods of the distance vector use to determine the shortest route Fr.OM one router for the next. Here the router counts the number of other router communication, must go through, each of whichIt represents one hop, and then creates a map of the best possible routes. Compared to the State Protocol, the interconnection algorithm cannot find out how fast a hop is compared to another and can eventually choose a slower route, even if it requires less hops. It also suffers from a delay when the router is added or removed from the network because it must re -calculate the hops to re -create its network map.

The routing protocol of the path vector is often used on the boundary of the network in what is referred to as the Border Gateway (BGP) protocol. In addition to counting the hops, the border router also advertises its availability by sending the PATH vector. Border routers of other networks then create their knowledge of roads outside and by watching these messages from each other.

In some cases, the protocols may be directed through an existing communication protocol. Whether they are routed depends on the Open Systems Connection Model Model, under which it operates, such as IS-ISIt is a non -created protocol. Internet protocol (IP) and TCP protocol) work in layers of three and four, and are two means to direct the protocol. The most remarkable are BGPs that run via TCP.
