There may be any number of NSAPs for an end system. These NSAP values must be known to the "end-to-end" communications software which runs in end systems. NSAPs are encoded as unique strings of characters (or numbers) which may be interpreted reading from left to right using the hierarchical model described previously. Each NSAP value in an end system specifies a different user of the Network Layer service. Intermediate systems route information based upon selected components of NSAPs received in transit.
For example, the telephone companies assign numbers to subscribers and publish some of the numbers in a telephone directory. In the OSI world, some names are included and registered in the standard. If applications want to exchange objects not included in the standard, such objects must be registered somewhere, so that no one else will use the same number for a different body part or a different number for the same body part. In the future, when a standard is approved which will require further registration of names, the procedure for registration and the registration authority will be approved at the same time.
A multiprotocol router is a device that will be able to distinguish between the OSI and non-OSI internetwork protocol data units. When a packet arrives at an intermediate Open Systems Interconnection 53 system, a Network Layer protocol identification field is checked and then the packet is passed to the appropriate module (either IP or OSI CLNP). Dual Protocol Hosts It is also possible to support multiple protocols on a single host. A dual protocol host has the complete OSI and other protocol suites available as part of its networking capabilities.
