One of the data link layer over network layer (or Layer-2 over UDP) protocols adopted by the industry is VXLAN. Now, as with any other overlay network protocol, its scalability is tied into how well it can handle the Broadcast, Unknown unicast and Multicast (BUM). [14] In Data Plane Learning the broadcast traffic is flooded to multicast group ...
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. [1] Multicast can be one-to-many or many-to-many distribution. [2] [3] Multicast differs from physical layer point-to-multipoint communication.
Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet. All-to-all communication is a computer communication method in which each sender transmits messages to all receivers within a group. [1]
For example, fiber optics and copper cables run directly from one machine to another to form a natural unicast media – data transmitted at one end is received by only one machine at the other end. However, as illustrated in the diagrams, nodes can forward packets to create multicast or broadcast distributions from naturally unicast media.
Key concepts in IP multicast include an IP multicast group address, [2] a multicast distribution tree and receiver-driven tree creation. [3] An IP multicast group address is used by sources and receivers to send and receive multicast messages. Sources use the group address as the IP destination address in their data packets.
In computer networking, unicast is a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. [1] Unicast is in contrast to multicast and broadcast which are one-to-many transmissions. [2]
Multicast routing is a method of transmitting to all subscribers registered in a group by one transmission unlike unicast routing (i.e. OSPF, RIP) which transmits 1: 1 necessary data. [2] To implement the multicast routing, Internet Group Management Protocol (IGMP) and a multicast routing protocol (Reverse-path forwarding, PIM-SM) for ...
Figure 1 - example nodes, links and interface indexes. We will work through SPBM behavior on a small example, with emphasis on the shortest-path trees for unicast and multicast. The network shown in Figure 1 consists of 8 participating nodes numbered 0 through 7. These would be switches or routers running the IEEE 802.1aq protocol.
