Abstract
Measures for processing data in a packet-switched network. At a first device in the network, an echo request packet is transmitted into the network. The echo request packet comprises a predetermined identifier. An echo response packet is received from a second device in the network. In response to the received echo response packet comprising the predetermined identifier, the received echo response packet is identified as a packet generated on the basis of an echo request packet originated from the first device, and an Internet Protocol (IP) address comprised in the received echo response packet is determined to be an IP address of the second device.
