!!! Overview [{$pagename}] is a method of transferring a [message] to all recipients simultaneously. [{$pagename}] to [unicast] in which a message is sent to only a single [Entity]. !! [Network] [{$pagename}] [{$pagename}] refers to transmitting a [packet] that the scope of the broadcast is limited to a [{$pagename}] [domain]. The [Message Passing Interface] ([MPI]) is the de facto standard on large computer clusters includes the MPI_Alltoall method. The [Internet Protocol Version 4] ([IPv4]), supports [{$pagename}], but the [{$pagename}] domain is the broadcasting host's subnet, which is typically small; there is no way to do an Internet-wide broadcast. Broadcasting is largely confined to [Local Area Network] ([LAN]) technologies, most notably [Ethernet] and [Token Ring], where the performance impact of broadcasting is not as large as it would be in a [Wide Area Network]. The successor to [Internet Protocol Version 6] ([IPv6]) also does not implement the broadcast method, so as to prevent disturbing all nodes in a network when only a few may be interested in a particular service. Instead it relies on [multicast] addressing - a conceptually similar one-to-many routing methodology. However, multicasting limits the pool of receivers to those that join a specific multicast receiver group. Both [Ethernet] and [IPv4] use an all-ones [{$pagename}] address to indicate a broadcast packet. [Token Ring] uses a special value in the [IEEE 802.2] control field. !! [{$pagename}] is Not supported on all [network] technologies Some [network] technologies __DO NOT__ support broadcast addressing; for example, * [X.25] * [Frame Relay] !!
