It was the first decentralized peer-to-peer network of its kind, leading to other, later networks adopting the model.was developed by Justin Frankel and Tom Pepper of Nullsoft in early 2000, soon after the company's acquisition by AOL.
When a link failure is detected, the algorithm notifies all reachable nodes that have cached the link in a distributed manner.The proposed approach improves the performance up to 30%-40% using different Qo S parameters like Packet Delivery Ratio (PDR), end to end delay, packet drop and energy consumption.Gnutella (possibly by analogy with the GNU Project) is a large peer-to-peer network.Route discovery phase is used in on-demand protocol.To avoid route discovery scheme route caching strategy is used.The proactive protocols maintain a up to date information of the nodes which periodically disseminates the topology updates through the network.
Whereas the on demand protocols make the discovery of the routes only when the routes are required.
In conventional approach only the nodes involved in the routing path knows about the route error and those node only update their cache.
But in U-DSR, by following distributed cache replacement algorithm, source node broadcasts the route error information of size 60 bytes to all its neighbours.
To make cache update for the broken links each node maintains the cache table information required for making the cache updates.
When a link failure is detected the algorithm notifies all the reachable nodes which have the cached link.
By using proactive cache updating the propagation of stale routes to other routes gets prevented.
