A Routing Algorithm is a method for determining the routing of packets in a node. The routing algorithms are as follows: Flooding. INTRODUCTION The main function of the network layer is routing packets from source machine to destination machine. Special multicast routers (built from PCs/Workstations) Construct virtual topology between them (overlay) Run routing protocol over virtual topology Virtual point-to-point links called tunnels » Multicast traffic encapsulated in IP datagrams » Multicast routers forward over tunnels according to computed virtual next-hop. Link state routing¶. Such a tree is called. Multicast can be one-to-many or many-to-many distribution. However, when multiple sources transmit information to the same destination, routing trees require a shared multicast tree. CHERITON Stanford University Multicasting, the transmission of a packet to a group of hosts, is an important service for improving. Computer networks are used today in, many aspects of manufacturing, including the manufacturing process itself.

CHERITON Stanford University Multicasting, the transmission of a packet to a group of hosts, is an important service for improving. Therefore, it is desired to design a new algorithm to jointly find the routing of a multicast tree and the selection of recovery nodes for multicast traffic. Sincoskie and Cotton [25] propose a multicast routing algorithm for link-layer bridges which supports a type of group in which all senders must also be members of the group. 4 Distance Vector Routing a) Distance Vector Routing uses the Bellman-Ford routing algorithm b) Distance vector is a distributed routing algorithm c) Shortest path computation is split across nodes (each router maintains its own routing. of Wireless LAN and Cellular Networks", Computer Networks, Novel Multicast Routing Algorithm.

Three algorithms are developed which are the Genetic Adaptive Routing Algorithm (GARA) for computer networks, the Synchronous Parallel Genetic Routing Algorithm (SPGRA) for computer networks, and the Asynchronous Parallel Genetic Routing Algorithm (ASPGRA) for computer networks. For link-state routing, a network is modelled as a directed weighted graph. It outperforms other existing algorithms over a range of problem instances. The router must know that there are nodes, which wish to receive multicast packets (or stream) then only it should forward. Consequently, the size of routing tables increases, as well, and routers can't handle network traffic as efficiently. improves a Multiobjective Multicast Routing Algorithm (MMA) presented in [4], to find a multicast tree optimizing several objective functions. of Wireless LAN and Cellular Networks", Computer Networks, Novel Multicast Routing Algorithm.

Ant Based Adaptive Multicast Routing Protocol (AAMRP) for Mobile Ad Hoc Networks A. Networks can be organized in hierarchies of many levels; e. It also determines whether a specific multicast group has been joined by the hosts on a attached interface. For multimedia applications, the routing algorithms should consider many quality of service (QoS) parameters such as delay, cost and so on to find a new route. When a router receives the multicast traffic, it will flood it on all of its interfaces except the interface where it received the multicast traffic on.
