CPC classification number: H04L43/0852 , H04L41/5009 , H04L41/5019 , H04L43/087 , H04L43/106 , H04L45/50
Abstract: A method and apparatus to provide hop-by-hop tracking for a communication network is described. In one embodiment, a router verifies that a next downstream router does not support tracking and in response terminates hop-by-hop tracking. An end router provides a compilation of all the timestamps back to the originating router.
Abstract translation: 描述了一种为通信网络提供逐跳跟踪的方法和装置。 在一个实施例中，路由器验证下一个下游路由器不支持跟踪，并且响应终止逐跳跟踪。 终端路由器提供所有时间戳的编译回到始发路由器。

Abstract: A method and apparatus to provide hop-by-hop tracking for a communication network is described. In one embodiment, each router verifies that a next downstream router supports tracking and in response, adds a tracking indicator and a timestamp to the data packet. An end router provides a compilation of all the timestamps back to the originating router.
