To avoid the default path and take the alternative path to find out the traffic of source to destination
OBJECTIVEOBJECTIVE
Computer Science & Engineering
Today’s wide-area Internet routing does not realize the full potential of the existing network infrastructure in terms of performance, reliability or flexibility
Today’s primary wide area routing protocol, BGP have a great difficult in managing Autonomous systems (ASes)
Disadvantages:Because ASes express their local routing policy during BGP
route advertisement by affecting the routes that are chosen and exported to neighbors
ISPs struggle to understand and configure their networks while end users are left to wonder why end-to-end connectivity is so poor
Large memory, processing, and message-passing overhead, dependent on behavior in other ASes

Computer Science & Engineering
To separate the issues of connectivity discovery and path selection
Our source routing system can be used to implement efficient overlay forwarding, select among multiple ingress/egress routers
Advantages:To increase the end-end performanceISPs to verify the policy-compliance of traffic.
It provide authenticating source routed packets
