Broadcast traffic is used to transmit a message to any reachable destination in the network without the need to know any information about the receiving party. When broadcast traffic is received by a network switch it is replicated to all ports within the respective VLAN except the one from which the traffic comes from.
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.
In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. 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.
Most IPv6 routers on the path of an anycast packet through the network will not distinguish it from a unicast packet, but special handling is required from the routers near the destination (that is, within the scope of the anycast address) as they are required to route an anycast packet to the "nearest" interface within that scope which has the ...
The addressing architecture of IPv6 is defined in RFC 4291 and allows three different types of transmission: unicast, anycast and multicast. [ 5 ] : 210 Motivation and origin
IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: unicast addressing, anycast addressing, and multicast addressing. [1] A unicast address identifies a single network interface. The Internet Protocol delivers packets sent to a unicast address to that specific interface.
The all-zeroes address is reserved as the subnet-router anycast address. [18] The subnet router anycast address is the lowest address in the subnet, so it looks like the “network address”. If a router has multiple subnets on the same link, then it has multiple subnet router anycast addresses on that link. [19]
PIM is not dependent on a specific unicast routing protocol; it can make use of any unicast routing protocol in use on the network. PIM does not build its own routing tables. PIM uses the unicast routing table for reverse-path forwarding. [1]: 56–57 There are four variants of PIM:
