For example: Infinity value is 16 hops. Routers send vectors every 30 seconds. Networking devices such as router etc Fig: Hop count Distance Vector Routing Protocol A distance vector routing algorithm is an intra-domain(within a network) routing . example, node U is the node computing the Link-State algorithm. The "distance" between neighboring (directly connected) nodes such as U and V is called the cost, c(U,V) for this example. The term distance is the cost from U to any other node (say W), in this case the. Unit 5 (Routing Protocols) 1) Describe distance vector routing protocol with one valid example. Explain working of RIP. () In distance vector routing, the least-cost route between any two nodes is the route with minimum distance. In this protocol, each node maintains a vector (table) of minimum distances to every node. The table at each node also guides the packets to the desired node.

Publisher Name.Distance Vector Routing!! Each router knows the links to its neighbors! Each router has provisional “shortest path” to every other router -- its distance vector (DV)! Routers exchange this DV with their neighbors! Routers look over the set of options offered by their neighbors and select the best one! Iterative process converges to set of shortest paths.

Distance Vector Routing Algorithm is a dynamic routing algorithm in computer networks. Distance Vector Routing Algorithm Example. Distance Vector Routing Algorithm is called so because it involves exchanging distance vectors. Each router prepares a routing table and exchange with its neighbors. Author. Node x maintains distance vector D x = [D x(y): y є N ] Node x maintains its neighborsʼ distance vectors For each neighbor v, x maintains D v = [D v(y): y є N ] Each node v periodically sends D v to its neighbors And neighbors update their own distance vectors D x(y) ← min v{c(x,v) + . 2 Destinatio Source m 10 ins in n m s 5 ins 8 mins m s in m 3 4 ins m s in 3 m 7 ns mi Total minimal distance is 4+3+5+2 = 14 mins Hop count Distance is defined in terms of hop count and direction.

Distance Vector • The distance vector routing is based on the Bellman-Ford algorithm • Every T seconds each router sends a list of distances to all the routers to its neighbor • Each router then updates its table based on the new information • Problems include fast response to good news and slow response to bad news. Also too many messages to update. Distance Vector Algorithm Basic idea: Nodes keep vector (DV) of least costs to other nodes These are estimates, Dx(y) Each node periodically sends its own DV to neighbors When node x receives DV from neighbor, it keeps it and updates its own DV using B-F: Dx(y) ←min v{c(x,v) + Dv(y)} for each node y N Ideally, the estimate Dx(y).
