Abstract
A facility is provided which obviates the need of administering network addresses in an internetwork composed of a plurality of networks by assigning to each network a common source address, rather than a unique network address. In addition, and when a connection is established between two of the networks, then, for the duration of the connection, each of those networks is dynamically associated with a respective second network address and a respective connection address, in which the connection address is used as a destination address. Accordingly, when one of the networks transmits a message to the other network, the internetwork identifies the proper connection as a function of the message destination address and then forwards the message to the intended recipient. In doing so, the internet changes the message source address to the second address associated with the one changes network and the message destination address to the second address associated with the other one of the two networks. Similarly, the source and destination addresses of a message received via the internet are respectively changed to the common address and associated connection address before the message is forwarded to the intended recipient.
