Line cards need packet based demultiplexing, space switch needs to be reconfigured on a packet-by-packet basis, need buffering Inherits complexity of packet switches. For each node that is still not in set M the set containing nodes to which shortest paths from the source have already been computeddetermine if its current distance from s is shorter than if the path came through the selected “next closest node.
A Systems Approach, L. Node 3 downstream node will detect the failure and send a ChannelStatus message to node 2 indicating the failure.

Tutlrial “next closest node” to set M. User-data flow Packets sent by host I-A with the label field in the packet header set to 1 are switched according to entries in the switch configuration tables at each switch following the path of the established virtual circuit. You can choose whether to allow people to download your original PowerPoint presentations and photo slideshows for a fee or free or not at all. The MPLS converged network vision. And their quality is top notch.
