摘要： A mechanism and associated protocol for performing Service Level Agreement (SLA) measurements in a communications network. The measurements obtained are used to perform various SLA parameter calculations such as delay, round trip delay, one way jitter and bandwidth related calculations. SLA measurement request and response messages are stamped with time and bandwidth counters by the client and remote ends of a connection. The resultant data is used to perform the calculation of SLA parameters.

摘要： A link based network protection path calculation mechanism wherein a protection route is calculated that is guaranteed not to traverse the link it is intended to protect. The mechanism takes advantage of the fact that the same color cannot pass twice through the same optical fiber. The protection path is determined by eliminating all colors from the logical topology of the network except for the color corresponding to the link to be protected before executing the search algorithm. This serves to guarantee that the protection path calculated will not traverse the same physical fiber as the link to be protected. Virtual colors can be assigned to the links running through fiber bundles such that they do not pass through the same fiber/bundle twice.
摘要翻译：一种基于链路的网络保护路径计算机制，其中计算保证不穿过其旨在保护的链路的保护路由。该机制利用了相同颜色不能通过相同光纤两次的事实。在执行搜索算法之前，除去与要保护的链路相对应的颜色的网络的逻辑拓扑以外的所有颜色，确定保护路径。这样做可以保证计算出的保护路径不会穿过与要保护的链路相同的物理光纤。可以将虚拟颜色分配给通过光纤束的链路，使得它们不通过相同的光纤/束两次。
