The Two-Way Active Measurement Protocol (TWAMP) is a technology that measures the round-trip performance of an IP network.
TWAMP uses UDP packets to collect statistics about the delay, jitter, and packet loss rate. In addition, TWAMP intelligently separates session control and traffic measurement to provide high security.
As networks rapidly develop and applications widely apply, various services are deployed to meet requirements in different scenarios. Therefore, networks encounter increasingly higher requirements for statistics collection. A tool that rapidly provides statistics about IP network performance is in urgent need.
Traditionally, network elements (NEs) themselves generate and maintain statistics about the IP network performance. To display statistics about the performance of an entire network, a network management system (NMS) is required to manage multiple NEs and collect statistics about these NEs. However, there may be no NMS deployed or the NMS may be incapable of collecting statistics.
TWAMP is therefore introduced. NEs themselves no longer need to generate or maintain statistics about the IP network performance. The performance management system manages only the TWAMP client and easily obtains statistics about the entire network.
Therefore, TWAMP applies to the scenario in which statistics about the IP network performance must be rapidly obtained but not necessarily be highly accurate.
