They are based on existing technologies like TCP/IP, HTML, Java VM or XML. Using such architecture, users will be able to plug printers, storage devices, speak- ers and any kind of device directly into a network and every other computer device and user on the network will know that the new device has been added and is avail- able. Each pluggable device will define itself immediately to a network device registry. The operating system will know about all accessible devices through some network registry. 10.10 TERMINAL FUNCTIONALITY - EXAMPLE With the new central position of the terminal in mind, there is a need for a huge number of protocols in modern terminals. By means of Figures 10.12, 10.13 and 10.14 it is possible to group the terminal functions in a way that corresponds to what has been applied in previous chapters of the book. Some functions in Figure 10.12 are core oriented according to Chapter 12 (ATM, SDH, SONET, MPLS, GMPLS) but an application of such standards in a CPN or a terminal could not be excluded. Security and service enabler functions are included in Figures 10.13 and 10.14.
