1. A method comprising:
- at each network device of a plurality of network devices which routes utility application traffic for a multi-terminal phase measurement unit session involving a plurality of utility devices that perform phase measurement operations in a utility network, receiving control information configured to cause each network device to monitor utility application traffic messages that pass through each network device from a specific first utility device to a specific second utility device via a particular utility application traffic stream; and
monitoring a header inserted into the utility application traffic messages based on the control information, wherein the header comprises bits which specify an identifier of the utility application traffic messages from the specific first utility device to the specific second utility device; and
identifying the utility application traffic from the specific first utility device to the specific second utility device based on the identifier.

Abstract
Techniques are provided to facilitate monitoring of utility application traffic streams. At a network device that routes utility application traffic for utility devices, control information is received, where the control information is configured to cause the network device to monitor utility application traffic that passes through the network device. The network device monitors a header inserted into utility application traffic messages based on the control information.
