As a novel carrier-level Ethernet technology,the Provider Link State Bridge(PLSB)technology can be used to address the issue of PBT\'s point to multi-point forwarding limitations.

On-demand multicast routing protocol with link status forecasting in Ad hoc network;

By sending Address Resolution Protocol(ARP)packet using the Network Driver Interface Standard(NDIS)protocol driver to the destination computer and parsing the ARP packet with the NDIS protocol driver can detect the link status quickly.

Meanwhile, basic functions, including “request link status”,“reset remote link”, general interrogation, clock synchronization, interrogation for one class user data, remote control, etc , are illustrated in detail.

This paper studies the relationship between link state information and the network BGP topology to analyze the impact of routing policies on BGP routing information propagation.

And it offers a king of arithmetic to split area that can be used to reduce the addi- tional cost to reaccount routing table when the link state is changed.

In order to reduce the overhead of networks, a new routing method, in which the nodes update the link states via using the frames transmitted by way of broadcasting in media access control layer, was proposed.

Low load and reliability flooding algorithm ERSN for link-state routing protocols;

To improve scalability,convergence and route quality of inter-domain routing,a link-state based inter-domain routing protocol is designed.

Moreover, the design judges link-state , then achieves system self-healing function.

Distance-vector routing protocol and link-state routing protocol are two common type of routing protocols widely used in computer networks.
