... Shortest Path Routing Algorithms used to determine the shortest path between two nodes according to some cost condition. The shortest path is the path with the least cost (the sum of the cost of the links on the path is minimum over all possible paths between the source and destination) Two m ...

Tapestry:A Resilient Global-Scale Overlay for Service Deployment
... Used micro benchmarks on a network of two nodes to isolate Tapestry’s message processing overhead. The sender establishes a binary network with the receiver and sends 10,0001 messages fore each message size The receiver measures the latency for each size using the interarrival time between the f ...

Introduction to Routing
... That is another static algorithm, in witch every incoming packet is sent out on every outgoing line except the one it arrived on. Flooding generates infinite number of duplicate packets unless some measures are taken to damp the process. One such measure is to have a hop counter in the header of eac ...
