represents an opportunity to leverage the existing wire media network infrastructure to enable the delivery of greater functionality several methods and techniques have been proposed but they are generally computationally intense hence costly the present invention may be employed in any type of network that uses wire media in whole or in part that is a network may use both wire media such as coaxial cable and wireless devices such as satellites as defined herein a network is a group of points or nodes connected by communication paths the communication paths may be connected by wires or they may be wirelessly connected a network as defined herein can interconnect with other networks and contain subnetworks a network as defined herein can be characterized in terms of a spatial distance for example such as a local area network lan a personal area network pan a metropolitan area network man and a wide area network wan among others a network as defined herein can also be characterized by the type of data transmission technology in use on it for example a tcp ip network and a systems network architecture network among others a network as defined herein can also be characterized by whether it carries voice data or both kinds of signals a network as defined herein can also be characterized by who can use the network for example a public switched telephone network pstn other types of public networks and a private network such as within a single room or home among others a network as defined herein can also be characterized by the usual nature of its connections for example.
