A device may receive a first session initiation protocol (SIP) message from another device, and may determine a first timestamp associated with the first SIP message. The first timestamp may represent a receipt time of the first SIP message by the device. The device may determine a second timestamp associated with a second SIP message. The second timestamp may represent a transmission time of the second SIP message by the device, and may be a response to the first SIP message. The device may determine a device latency value representing a difference between the second timestamp and the first timestamp. The device may provide the second SIP message to the other device at the transmission time. The second SIP message may include the device latency value.

Measuring session initiation protocol (SIP) messaging latency

A device receives packet information associated with a traffic flow and a network segment. The network segment includes a portion of a network via which the traffic flow is transmitted. The device associates the received packet information with a period of time. The device determines that the period of time has expired, and aggregates the received packet information based on determining that the period of time has expired. The device determines a network performance parameter associated with the traffic flow over the network segment based on the aggregated packet information. The device generates performance information that identifies the network performance parameter, the traffic flow, and the network segment. The device provides the performance information.
