Implementing distance vector routing protocol in java

The distance vector routing protocol and link state routing protocol come under the interior gateway protocols The periodic updates of the distance vector routing protocol is 30 to 90 seconds and the Based on the network size and an IP addresses implemented, it typically do not need the high Distance Vector routing protocols use frequent broadcasts (255.255.255.255 or FF:FF:FF:FF) of their entire routing table every 30 sec. on all their interfaces in order to communicate with their neighbours. The bigger the routing tables, the more broadcasts. This methodology limits significantly the size of Distance vector routing is so named because it involves two factors: the distance, or metric, of a destination, and the vector, or direction to take to get there. Routing information is only exchanged between directly connected neighbors. This means a router knows from which neighbor a route was Distance-vector routing protocols like RIP were fine for networks comprised of equal speed links, but struggled when networks started to be built out The key feature of distance vector protocols is that each router relies on the reachability information advertised by its neighbors to deduce its best route Distance vector routing protocols include the following: Routing Information Protocol (RIP) for A typical distance vector routing protocol uses a routing algorithm in which routers periodically If routers implement the method of rigid, system-independent timers, then all routers sharing a Proactive or table-driven routing protocols continuously maintain routing information so the routes in the network are always up to date. Currently, complete routing table broadcasts are not implemented, only the broadcasting of changes in the routing table using periodic hello messages. In addition to distance vector-based routing, the second basic algorithm used for routing is the link-state algorithm. Link-state protocols build routing RFC 2328 describes OSPF link-state concepts and operations. Link-state routing protocols collect routing information from all other routers in the Pure distance vector protocols are rare; the only one really remaining in any sort of use is RIP. EIGRP, a Cisco proprietary protocol, is also technically distance vector, but it Link-state protocols function by advertising each router's connected interfaces to every other device in the routing domain. Distance Vector routing protocols pass periodic copies of routing table to neighbour routers and accumulate distance vectors. In distance vector routing protocols, routers discover the best path to destination from each neighbour. The routing updates proceed step by step from router to router.

The routers running a distance vector routing protocol will automatically send periodic updates even if there are no changes in the network. A router can verify all the known routes and alters its local routing table on the basis of the updated information received from neighbouring routing.
