摘要： A method is disclosed for implementing and reporting network measurements between a source of probe packets and an element, such as a router. The invention exploits commonly implemented features on commercial elements. By exploiting these features, the expense of deploying special purpose measurement devices can be avoided. In one aspect of the invention, a plurality of probe packets is transmitted in a packet network with each of the probe packets having the same key and the same aggregation characteristic. A report is then received from an instructionless element regarding the plurality of probe packets, thereby enabling measurement of a parameter of the packet network.

摘要： A method and system for rendering a plurality of multicast trees for presentation on a display. A multicast routing state may be accessed from a plurality of routers in a multicast group. The multicast routing state may include identification of at least one of an upstream router or a downstream router. A plurality of multicast trees may be identified from the multicast routing state of the plurality of routers. Each of the plurality of multicast trees may indicate a plurality of paths for a data packet from an originating router to selected routers among the plurality of routers. At least two of the plurality of multicast trees may be rendered on a display as an overlapping multicast tree. The overlapping multicast tree may include the plurality of paths for the data packet from the originating router to the selected routers for each of the at least two of the plurality of multicast trees.
摘要翻译：一种用于呈现多个多播树以在显示器上呈现的方法和系统。可以从多播组中的多个路由器访问组播路由状态。组播路由状态可以包括上行路由器或下游路由器中的至少一个的标识。可以从多个路由器的多播路由状态来识别多个多播树。多个多播树中的每一个可以指示多个路由器，用于数据分组从始发路由器到多个路由器中的选择的路由器。多个多播树中的至少两个可以在显示器上呈现为重叠的多播树。重叠的多播树可以包括用于从多个多播树中的至少两个中的每个的始发路由器到所选路由器的数据分组的多条路径。
