Backbone Technology

Abstract

Chapter 2 has discussed the architecture of PervNet where the backbone is depicted as the core of the network model. In fact, backbone constitutes the foundation technology of PervComp, which is to be used in any pervasive application for transmitting multimedia information containing plaintext, hypertext, audio, images, video, and data. In PervNet, devices communicate over an access network that connects to a core network—commonly known as a network backbone. For example, a pervasive device may be connected to a wired/wireless local area network (LAN), which is connected to other networks either directly or through a backbone of wide area network (WAN). It may so happen that data need to be transferred from one network to another, or from one network segment to another. For data to be transmitted across networks usually requires an interface device, such as a bridge, gateway or router. An interconnection of networks is commonly known as an internetwor (or internet in short). Each part of an internet is a subnetwork (or subnet in short). Internetworking is becoming more important especially as more devices are becoming pervasive and they need to intercommunicate with each other. The Internet is a special kind of internet (that uses TCP/IP suite), which is growing at an enormous speed to be the kernel of the backbone for PervNet.
