A gateway is a network point that acts as an entrance to another network by translating between two different protocols. A gateway allows for communications between two networks that use different protocols, or which use the same protocols but do not otherwise communicate. A gateway routes data and controls information among the host computers during "sessions." Gateway processes the packets according to routing information and protocol conventions encapsulated in headers of the packets. During operation, the gateway makes decisions on how packets traverse the gateway from an input side to an output side. The data and control information can be organized into cells, packets, datagrams, or messages, depending on a communications protocol layer. Using gateways, a Web server can support data types and resources, and access information outside of the Internet. A gateway may contain devices such as protocol translators, rate converters, impedance matching devices, fault isolators, or signal translators.
