Multicast routing is a technique used in computer networks to optimize the transmission of data from one sender to multiple recipients. Instead of sending separate copies of the data to each recipient individually, multicast routing allows the sender to transmit the data once, and the recipients who are interested in receiving it form a multicast group. This method is particularly beneficial in scenarios where one-to-many communication is required, such as in voice over IP (VOIP), video on demand (VOD), video conferencing, and IP television (IPTV) applications. For example, during a live video conference, the video stream from the sender is multicast to a specific multicast group. Computers, devices, and IP phones that belong to that multicast group can receive the video stream simultaneously. When you enable multicast routing on your Firebox, it functions as a local multicast router. It takes on the responsibility of forwarding multicast traffic from the source to the intended recipients within your network. By efficiently handling multicast transmissions, the Firebox helps ensure that the multicast data reaches the receivers without unnecessary duplication or delays. [more]

IP multicast routing is a technique used in computer networks to efficiently deliver data packets from a single sender to multiple recipients. It is specifically designed for applications where data needs to be distributed simultaneously to a group of interested receivers. In traditional unicast communication, a sender sends packets to individual receivers using their unique IP addresses. This creates a point-to-point connection between the sender and each receiver, resulting in duplicate transmissions if multiple receivers are interested in the same data. Unicast is inefficient for one-to-many or many-to-many communication scenarios. Multicast routing, on the other hand, allows a sender to transmit a single copy of a packet, and network routers replicate and forward it to all interested receivers. This saves network bandwidth and processing resources, as the data is distributed only once. Multicast routing uses special IP multicast addresses, typically in the range of 224.0.0.0 to 239.255.255.255, to identify multicast groups. To enable IP multicast routing, routers in the network need to support multicast routing protocols such as Protocol Independent Multicast (PIM). These protocols enable routers to exchange information about multicast groups and determine the optimal path for forwarding multicast traffic. Routers maintain multicast routing tables that specify the outgoing interfaces and next-hop routers for forwarding multicast packets. When a sender wants to send data to a multicast group, it encapsulates the data in a multicast packet and sets the appropriate multicast IP destination address. The routers along the path use the multicast routing tables to determine how to forward the packet to all interested receivers. Receivers interested in receiving multicast data join the multicast group by sending a membership request to the nearest router. The router adds the receiver to the multicast distribution tree, and subsequent multicast packets are forwarded [more]
