摘要： A data network wherein network links have an assigned service weight and a restoration weight that are used as factors for respectively determining an optimum primary data path and a back-up data path through the network. The restoration path is used in the event of a failure of the primary service path and a Dijkstra or similar algorithm may be used for determining these paths. Service weights may be assigned to the links to prioritize finding the shortest possible path, whereas restoration weights may be assigned to the links to find a path with the maximum available capacity.

摘要： A system and method is disclosed that assures component circuits transported in aggregated circuits restore correctly after an aggregated circuit fault. The system and method implements component circuit tail segment integrity checks whenever an aggregated circuit is restored in a higher level of a network hierarchy. Switches at both ends of an aggregated circuit perform circuit integrity checks of the tail segments of every component circuit. A failure of the component circuit integrity check on any component circuit causes that component circuit to be released and restored end-to-end.

摘要： Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.

摘要： The distribution of replica caches of information is dynamically optimized among the regions of a network, based upon the changing usage patterns. Initially, a single server in a first region stores the primary copy of information. A router in the first region receives service request messages from the plurality of users throughout network, directed to the server storing the primary copy. To determine if it is justified to deploy a replica cache, the router transmits a monitor request message to other routers in other regions of the network, requesting them to monitor all service requests in their respective regions, being directed to the primary copy in the first server. The first router then computes an optimum assignment of a replica copy of the information, for storage in at least one newly assigned server in the network. The first router transmits a replication message to the newly assigned server, to enable it to store the replica copy of the information and provide service to user terminals in a newly assigned set of regions of the network. The first router also transmits an assignment message to the other routers in the network, to enable them to redirect traffic from their respective regions to either the newly assigned server or to the first server.
摘要翻译：基于不断变化的使用模式，在网络区域之间动态优化信息副本缓存的分布。最初，第一区域中的单个服务器存储信息的主副本。第一区域中的路由器从网络中的多个用户接收服务请求消息，指向存储主副本的服务器。为了确定部署副本缓存是否合理，路由器向网络其他区域的其他路由器发送监视请求消息，请求它们监视其各自区域中的所有服务请求，并将其指向第一个副本服务器。然后，第一路由器计算信息的副本副本的最佳分配，用于存储在网络中的至少一个新分配的服务器中。第一路由器向新分配的服务器发送复制消息，使其能够存储信息的副本，并向网络的新分配的一组区域中的用户终端提供服务。第一路由器还向网络中的其他路由器发送分配消息，以使得它们能够将来自其各自区域的流量重定向到新分配的服务器或者到第一服务器。
