TWAMP协议定义了两种架构:标准框架和轻量级架构。TWAMP Light是TWAMP协议的轻量级架构,简化了建立性能测量会话的控制协议,提高了测试性能,越来越多的厂家青睐并支持TWAMP Light技术。 1.2技术优点 常见的丢包、时延测量技术包括NQA(Network Quality Analyzer,网络质量分析)和RFC 6374/6375(MPLS网络的丢包和时延测...
图1是TWAMP中逻辑实体的关系示意图,如图1所示:RFC5357标准中轻量级TWAMP(TWAMPLight)是简化版的TWAMP,相对于TWAMPFull,只会在发射端首先发起TWAMP-Test报文,其中,发射端12与反射端14采用TWAMP-Test报文进行交互,服务端16与客户端18采用TWAMP-Control报文进行交互。 图2是TWAMPLight模型中逻辑实体的关系示意图,如图2所示...
These tests measure the maximum capabilities of a service or a circuit by leveraging RFC-2544 and Y.1564 tests. The benefits of these tests is to take advantage of far-end responder capabilities to eliminate the need for service truck rolls. To read more about TWAMP, specific use-case ...
The procedure uses the mechanisms defined in RFC 5357 (Two-Way Active Measurement Protocol (TWAMP) Light) and Simple Two-Way Active Measurement Protocol (STAMP) for Delay Measurement, and also uses the mechanisms defined in this document for Loss Measurement. The procedure specified is applicable ...
TWAMP server and the session reflector on the same Cisco device. In this configuration, port 862 is the (default) port to be used by the TWAMP server to listen for connection and control requests. The port for the server listener is the RFC-spec...
RFC 5357 Two-Way Active Measurement Protocol October 2008 limited to a simple echo function. However, the most common facility for round-trip measurements is the ICMP Echo Request/Reply (used by the ping tool), and issues with this method are documented in Section ...

According to another embodiment the Sender in SGW uses the control procedure defined in IETF RFC 5357 “A Two Way Active Measurement Protocol” to establish a TWAMP connection with the Reflector in the eNodeBs. This involves sending control messages to a well-known port. The sender normally se...
