Abstract
A methodology and network tool for evaluating one-way directional delays in a packet network is described. The invention provides for a discrimination of the directional components of the delay experienced by packets travelling between nodes in a network. This identification of the directional delay component assists in an understanding of network behaviour and can be represented on a graphical user interface. Such methodologies are achieved without requiring clock synchronisation between clocks at each of the nodes.
