Link-state routing protocols are one of the two main classes of routing protocols used in packet switching networks for computer communications, the others being distance-vector routing protocols. [1] Examples of link-state routing protocols include Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). [2] The ...
The link state protocol is used to discover and advertise the network topology and compute SPTs from all bridges in the SPT Region. In SPBM, the backbone MAC (B-MAC) addresses of the participating nodes and also the service membership information for interfaces to non-participating devices ( User–network interface (UNI) ports) is distributed.
Link State Packet (LSP) is a packet of information generated by a network router in a link state routing protocol that lists the router's neighbors. Link state packets can be further defined as special datagrams that determine the names of and the cost or distance to any neighboring routers and associated networks .
Routing protocols, according to the OSI routing framework, are layer management protocols for the network layer, regardless of their transport mechanism: IS-IS runs on the data link layer (Layer 2) Open Shortest Path First (OSPF) is encapsulated in IP, but runs only on the IPv4 subnet, while the IPv6 version runs on the link using only link ...
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).
This is in contrast to exterior gateway protocols, primarily Border Gateway Protocol (BGP), which is used for routing between autonomous systems. [5] IS-IS is a link-state routing protocol, operating by reliably flooding link state information throughout a network of routers. Each IS-IS router independently builds a database of the network's ...
One or more routing protocols suitable to the actual network physical topology are required. 802.11s requires the Hybrid Wireless Mesh Protocol, or HWMP [2] to be supported as a default. However, other mesh, ad hoc ( Associativity-Based Routing , Zone Routing Protocol , and location based routing ) or dynamic link-state routing ( OLSR , B.A.T.M ...
The Optimized Link State Routing Protocol (OLSR) [1] is an IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol , which uses hello and topology control (TC) messages to discover and then disseminate link state information throughout ...
