A distance-vector routing protocol in data networks determines the best route for data packets based on distance. Distance-vector routing protocols measure the distance by the number of routers a packet has to pass; one router counts as one hop. Some distance-vector protocols also take into account network latency and other factors that ...
Poison Reverse is often used within distance-vector routing to solve the count-to-infinity problem. Practically, poison reverse can be thought of as an alternative to split horizon. With poison reverse, route advertisements that would be suppressed by split horizon are instead advertised with a distance of infinity.
For example, if the current node A is marked with a distance of 6, and the edge connecting it with its neighbor B has length 2, then the distance to B through A is 6 + 2 = 8. If B was previously marked with a distance greater than 8, then update it to 8 (the path to B through A is shorter).
A distributed variant of the Bellman–Ford algorithm is used in distance-vector routing protocols, for example the Routing Information Protocol (RIP). The algorithm is distributed because it involves a number of nodes (routers) within an Autonomous system (AS), a collection of IP networks typically owned by an ISP. It consists of the following ...
Destination-Sequenced Distance-Vector Routing (DSDV) is a table-driven routing scheme for ad hoc mobile networks based on the Bellman–Ford algorithm. It was developed by C. Perkins and P. Bhagwat in 1994. The main contribution of the algorithm was to solve the routing loop problem. Each entry in the routing table contains a sequence number ...
Examples of link-state routing protocols: Open Shortest Path First (OSPF) Intermediate system to intermediate system (IS-IS) Advanced distance vector routing protocols have both the features of distance vector routing protocols and link-state routing protocols. One example is Enhanced Interior Gateway Routing Protocol (EIGRP).
Ad hoc On-Demand Distance Vector (AODV) Routing is a routing protocol for mobile ad hoc networks (MANETs) and other wireless ad hoc networks.It was jointly developed by Charles Perkins (Sun Microsystems) and Elizabeth Royer (now Elizabeth Belding) (University of California, Santa Barbara) and was first published in the ACM 2nd IEEE Workshop on Mobile Computing Systems and Applications in ...
Like distance-vector protocols, B.A.T.M.A.N. does not try to determine the entire route, but by using the originator-messages, only the packet's first step in the right direction. The data is handed to the next neighbor in that direction, which in turn uses the same mechanism. This process is repeated until the data reaches its destination.
