Session-identifer based TWAMP data session provisioning in computer networks

摘要

Techniques are described for performing session identifier (“SID”) based two-way active measurement protocol (TWAMP) data session provisioning between two endpoints in a computer network. According to the techniques, a SID assigned to each data session is used to uniquely identify the data session, instead of a source and destination address/port pairs. A TWAMP server may generate a unique number as a SID of a data session during negotiation of the data session. The disclosed techniques include extending TWAMP control messaging to include a communication mode for the SID-based TWAMP data session provisioning. The disclosed techniques further include extending TWAMP data messaging to include the SID of the data session in each test packet for the data session. In this way, a TWAMP session sender and a TWAMP session reflector may associate received test packets with a certain data session based on the SID included in the received test packets.
