Multihoming support based on mobile node protocol LIN6
... IPv4/IPv6, the network address of a node denotes both its identity and its location. In LIN6 architecture, we divide a 128bit-long IPv6 address into two parts. The first half is called “locator” and the second half “identifier”. A locator only depicts a location and an identifier only depicts an identi ...

Tutorial on Signaling System 7 (SS7)
... SSPs are switches that originate, terminate or tandem calls. An SSP sends signaling messages to other SSPs to setup, manage and release voice circuits required to complete a call. An SSP may also send a query message to a centralized database (an SCP) to determine how to route a call (e.g., a toll-f ...
