The sendMsg function is already implemented in node.h; you must complete the recvMsg function in order to process a routing table update from a neighbor at a given node. The recvMsg function will run the Bellman Ford update algorithm of the distance vector routing protocol, and update its routing table as required.

- This project investigates and implements the distance-vector routing distribution algorithm (DVR) in Java, and extends this algorithm by implementing a distance-vector strategy by F.C.M. Lau and Guihai Chen that supports unidirectional links (UDVR). 1 A variety of graphs are input into both the original DVR and UDVR algorithms to illustrate the various scenarios that the unidirectional.
- Distance Vector Table Initialization - Distance to itself = 0; Distance to ALL other routers = infinity number. Distance Vector Algorithm – A router transmits its distance vector to each of its neighbors in a routing packet. Each router receives and saves the most recently received distance vector from each of its neighbors.

Distance Vector Algorithm is a decentralized routing algorithm that requires that each router simply inform its neighbors of its routing table. For each network path, the receiving routers pick the neighbor advertising the lowest cost, then add this entry into its routing table for re-advertisement. To find the shortest path, Distance Vector Algorithm is based on one of two basic algorithms: the Bellman-Ford and the Dijkstra algorithms.
Routers that use this algorithm have to maintain the distance tables (which is a one-dimension array — “a vector”), which tell the distances and shortest path to sending packets to each node in the network. The information in the distance table is always upd by exchanging information with the neighboring nodes. The number of data in the table equals to that of all nodes in networks (excluded itself). The columns of table represent the directly attached neighbors whereas the rows represent all destinations in the network. Each data contains the path for sending packets to each destination in the network and distance/or time to transmit on that path (we call this as “cost”). The measurements in this algorithm are the number of hops, latency, the number of outgoing packets, etc.
The Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph. It is slower than Dijkstra’s algorithm for the same problem, but more versatile, as it is capable of handling graphs in which some of the edge weights are negative numbers. Negative edge weights are found in various applications of graphs, hence the usefulness of this algorithm. If a graph contains a “negative cycle” (i.e. a cycle whose edges sum to a negative value) that is reachable from the source, then there is no cheapest path: any path that has a point on the negative cycle can be made cheaper by one more walk around the negative cycle. In such a case, the Bellman–Ford algorithm can detect negative cycles and report their existence.
