Patent ID: 8654790

Claim:
A method of testing a communication device or network under test, comprising: at a remote test system, generating portions of test packets separated by time intervals, encapsulating the portions of test packets thereby forming encapsulated packets, and adding timing information to the encapsulated packets so as to preserve the portions of the test packets and information related to the time intervals, wherein the encapsulated packets preserve headers of the portions of test packets; transmitting the encapsulated packets over a transport network from the remote test system to a local test device; at the local test device, decapsulating the encapsulated packets so as to obtain replay packets and the timing information, wherein the replay packets include the portions of the test packets; and, transmitting the replay packets separated by the time intervals from the local test device to the communication device or network under test, wherein the timing information is used by the local test device to reproduce the time intervals so as to imitate a stream of the test packets generated at the remote test system.
