Method of re-routing traffic in a communications network (1) in the event of a fault (3) on a
path across the network, the method comprising, determining whether a first node (4) …

A router detects a network failure and responsive to that failure, floods a fast failure
notification message out a set of interfaces of the router. The fast failure notification message …

BACKGROUND A computer network is a collection of interconnected com puting devices
that can exchange data and share resources. In a packet-based network, the computing …

BACKGROUND Protocol Independent Multicast Sparse Mode (PIM-SM)(see, IETF RFC4601
of August 2006) is a well known and commonly adopted protocol for constructing and …

A failure detection mechanism provides enhancements to PIM-SM based fast re-route
techniques. A network node upon detecting a loss of connection determines whether it can …

A method in a router for initiating fast flooding based fast convergence to recover from a
network failure is disclosed. The method also starts with detecting a network failure …
