Technical Details

what runs on :862

TWAMP-Control uses TCP port 862 and carries a binary control protocol. A client connects to the server, receives a server greeting, negotiates a security mode, and exchanges session-setup and session-start messages before test traffic begins. Measurement packets are sent over separate UDP test sessions, commonly associated with the TWAMP-Test service on UDP port 876; TWAMP-Control itself does not carry the measurement stream.

security overview

Do not expose TWAMP-Control broadly to the internet. Depending on implementation and negotiated mode, the control connection may be unauthenticated or may use authentication and encryption; an unauthenticated client can potentially create measurement sessions and consume device or link resources. Restrict access with network ACLs, enable the strongest supported security mode, and rate-limit or monitor test-session creation.

category: Network Services
usage: TWAMP-Control is the TCP control service used by TWAMP clients and servers to negotiate and manage active network measurements such as latency, jitter, and packet loss. It is typically found on routers, dedicated measurement appliances, and network-monitoring agents; the actual test traffic uses negotiated UDP sessions.
