摘要：A system and method for measuring network delay in an IP network, comprising

detecting request and corresponding request transport acknowledgement messages ata monitoring point in the network, calculating an uplink network delay based upon thetime elapsed between the request and corresponding request transport

acknowledgement messages;, detecting response and corresponding response transportacknowledgement messages at the monitoring point, wherein the response message issent in response to the request message, calculating a downlink network delay basedupon the time elapsed between the response and corresponding response transportacknowledgement messages; and calculating an end-to-end network delay by averaginga sum of the uplink and downlink delays, wherein the end-to-end network delayrepresents a time required for an IP message to travel from a user device to a networkdestination. An end-to-end user-perspective delay may also be calculated from theuplink and downlink delays.
