...reliably transmit information (in frames) from point A to point B. It is commonly used by ISPs, DSL modems, and routers to transmit IP packets over WAN links (T1, E1, T3, E3, DSL, Ethernet, and ATM transmission lines).
Multiple PPP links can be combined to form a Multi Link PPP (ML-PPP) to achieve greater bandwidth. For example, five T1 lines can be shared to get 5x the bandwidth of a single T1 line. In this case, the transmitter fragments packets and transmits over separate T1 lines. At the receiver, the fragments are assembled in the right order to reconstruct the packet. Whether PPP or ML-PPP, a single packet is transmitted completely (fragmented or not) and cannot be interrupted. Multi-Class Multi Link PPP permits interruption of one packet transmission by another, and then resumption of the original.
GL's MAPS™ (Message Automation and Protocol Simulation) platform is a general purpose Protocol Emulator for various protocols encountered in the telecom space. MC-MLPPP is one such advanced protocol simulator/tester for Multi Class, Multi Link, PPP protocols over TDM (T1 E1). The tester can simulate a complete PPP or MLPPP link between two peers, with MLPPP signaling conforming to IETF specifications.
MAPS™ MLPPP supports testing network elements, error tracking, regression testing, conformance testing, and load testing/call generation. The test tool can run pre-defined test scenarios against MLPPP test objects in a controlled & deterministic manner. The test tool also incorporates the flexibility to modify call parameters & message contents (arbitrary manipulation of messages, information elements and message sequence on the different protocols).
MAPS™ MLPPP conformance scripts are suitable for conformance tests and functional tests, where test objects can be accurately, reliably and comfortably validated for compliance with IETF standard. It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing.
