INTERFACES Four main interfaces are defined in GSM networks: • Um Interface Between the MS and the BTS • Abis Interface Between the BTS and the BSC • A Interface Between the BSC and the MSC • MAP-x Between the MSCs as well as between MSC and HLR/ VLR/AuC. The Um interface uses a combination of FDMA and TDMA access techniques.
Problems that were identified with RIP were addressed in a subsequent release called RIPv2. RIP runs on top of UDP and uses port 520. RIPng is the version of RIP that is defined for IPv6 networks and is documented in RFC2080. RIPng uses port 521 for sending and receiving packets.

Each pair of request and response is treated as an independent message exchange. • The notion of metadata is important: Information about the resources is often included in Web transfers and can be used in multiple ways. HTTP relies on the concept of an URI. This naming mechanism allows resources to reside anywhere on the Internet. A resource can have the same URI associated with it forever, although the contents of the resource or its representation can change over its lifetime. A URI denotes a resource independent of its current location or the name by which it is known.
