An '''internetwork''' (usually given as '''internet''' for short; the use of the generic term is distinguished from references to ''the'' [[Internet]] by the use of the capital letter in the latter) is a commucation system consisting of a number of [[physical network]]s (such as [[Ethernet]]s), along with a collection of [[router]]s (the current term), the [[packet switch]]es which connect them into an integrated system.

An internetwork is tied together with an [[internetworking layer]], a [[protocol]] which offers direct [[datagram]] carriage across the entire internetwork, so that it is invisible to a [[host]] using that protocol where the eventual destination is, how many (and which) networks have to be traversed to get to it, etc. It just hands its [[packet]]s to the nearest router, and they take care of everything else.

Each individual physical network has a protocol which specifies how packets are carried from one interface to that network to another; these protocols will vary from network type to network type. The internetworking layer serves to insulate everything connected to the internet from these variations; it is the same for all hosts and routers throughout the internet.

All internetworking designs are heavily influenced by the ground-breaking [[CYCLADES]] network.
