Network delay is a therefore a critical performance measure for packet-switching communications.
Their measurement, the measurement of delays across member networks of a catenet, becomes important for catenet investigations. An effective way to measure catenet delays is by means of packet header timestamping. Header timestamping allows monitoring of catenet delays for user traffic, such as the case of Ft. Bragg users accessing ISID across the catenet. Packet header timestamping is also compatible with the use of test packets for catenet delay measurement.
