Description
Summary:The X.25 network is sometimes a mystical concept. A number of common misunderstandings about X.25 networks are in the areas of: 1. flat rate, 2. unrestricted access, and 3. network reliability. A telephone system charges customers a flat rate for a leased telephone line, no matter how much is used. With packet-switched networks, the user pays only for what he sends, resulting in lower cost of data transfer, increased network reliability, and a well-defined standard user interface (X.25). In packet-switching networks, nobody has restricted access to any physical assets. The network can multiplex many users' packets over the same wires since it does not assign physical assets to users. The increased network reliability of packet-switched networks is a result of the built-in redundancy provided by the basic network structure. Users of these networks will find it easier to use equipment from multiple vendors. However, compatibility with X.25 networks is no guarantee that 2 pieces of equipment can communicate with each other, although X.25 will reduce interconnectability problems overall.
