Probing a Network

摘要

A method is presented of probing a network using probing with a probe packet pair, the pair comprising a first probe packet (L1) and a second probe packet (L2), and wherein L1>L2. The L1 probe packet is transmitted before L2 and the probe packets are arranged to be back-to-back on the last link. Use of the method provides the capacity of the last link in the probed path. The method may be run from a gateway in a network to probe aspects of the network and is suitable for probing a domestic network behind a home gateway. A use for the method is also described.

1. A method of probing a network using a probe packet pair, the network comprising at least one network path, the network path comprising one or more network links, and the probe packet pair comprising a first probe packet L1 and a second probe packet L2, wherein the size of L1 is greater than the size of L2,
the method comprising: transmitting L1 and L2 over the network path, wherein L1 is transmitted before L2; and arranging L1 and L2 to be back-to-back on the last of the one or more links of the network path.
