Routing Algorithms: Distance Vector Routing
Edit
Distance Vector Routing
- It measures the distance by the number of routers a packet has to pass, one router counts as one hop. It determines the best route across network routers on which a distance-vector protocol is implemented by exchanging information with one another, usually routing tables plus hop counts for destination networks and possibly other traffic information. Distance-vector routing protocols also require that a router informs its neighbors of network topology changes periodically, thus keeping them up to date with the changes that are taking place.
- The term distance vector refers to the fact that the protocol manipula…

Congestion Control, Open Loop, Closed Loop, Leaky Bucket & Token Bucket Algorithm
Edit
Congestion Control
- If the Internet is considered as a Queue of packets, where transmitting nodes are constantly adding packets and receiving nodes are removing packets from the queue. So here we consider a situation where too many packets are present in this queue such that constantly transmitting nodes are pouring packets at a higher rate than receiving nodes are removing them. This will obviously degrade the performance, and such a situation is termed as Congestion. Main reason of congestion is more number of packets into the network than it can ha…
