摘要： In one embodiment, a network device (e.g., a master controller) may detect an event on a current path in a computer network from a local network domain to a destination address prefix of a remote domain. In response, the device may dynamically (e.g., intelligently) determine a trace target destination address within the destination address prefix, and may perform (or request performance of) a Traceroute of the current path and a selection of alternate paths in the network from the local network domain to the trace target, where the Traceroute is adapted to obtain per-hop measurements along the respective traced path. The measurements may then be stored, for example, to be used for optimal path selection, fault identification reporting, etc.

摘要： In one embodiment, a method includes obtaining a first packet included in a flow to be forwarded to a border router, and replicating the first packet to create a duplicate. The first packet is forwarded onto a first set of links, and the duplicate is forwarded onto a second set of links, to the border router. First information relating to the first packet and the first set of links, and second information relating to the duplicate and the second set of links, is obtained. The first information and the second information are used to determine whether to forward the flow on the first set of links. The first set of links is used to forward the flow if it is determined that the first set of links is to be used to forward the flow, otherwise the second set of links is used to forward the flow.

摘要： A technique performs route optimization of services provided by one or more service providers (SPs) for communication links that are combined in a computer network. According to the novel technique, performance characteristics and statistics (“link data”) for two or more combined links are merged to form link data for a single “virtual combined link.” Route optimization techniques (e.g., priority-based route optimization) may then be applied to one or more virtual combined links based on the combined link data, in addition to link data for zero or more conventional single links (physical or virtual). Illustratively, a route optimization technique may be used in accordance with the present invention to efficiently and accurately minimize costs associated with services provided by a plurality of SPs, wherein each SP charges for utilization of its service based on a tiered pricing structure. The tiered pricing structure comprises one or more tiers, wherein each tier correlates to an amount of service provided by the SP and an associated cost.
摘要翻译：一种技术对由一个或多个服务提供商（SP）提供的用于组合在计算机网络中的通信链路的服务的路由优化。根据新技术，两个或多个组合链路的性能特征和统计（“链路数据”）被合并以形成用于单个“虚拟组合链路”的链路数据。路由优化技术（例如，基于优先级的路由优化）可以然后除了用于零个或更多个常规单个链路（物理或虚拟）的链路数据之外，还可以基于组合的链路数据将其应用于一个或多个虚拟组合链路。说明性地，根据本发明可以使用路由优化技术来有效和准确地最小化与由多个SP提供的服务相关联的成本，其中每个SP基于分层定价结构为其服务使用收费。分层定价结构包括一个或多个层，其中每个层与由SP提供的服务量和相关联的成本相关。
