2. OBJECTIVE
To avoid the default path and take the
alternative path to find out the traffic of source to
destination
Computer Science & Engineering
3. EXISTING SYSTEM
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
4. PROPOSED SYSTEM
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 performance
ISPs to verify the policy-compliance of traffic. It provide
authenticating source routed packets

Much of the complexity of Internet routing policy
stems from inflexibility of existing routing protocols
