摘要： A node 800 of a multi-layer communication is capable of routing a message signal via one or more different layers (for example a PSC layer, TDM layer, LSC layer) in the multi-layer communication network. The node 800 comprises a first interface 801 for receiving a path message 803 containing routing information for routing an associated message signal through the multi-layer communication network. One or more second interfaces 805i to 805N are provided for transmitting a message signal to one or more respective layers in the multi-layer communication network. A processing unit 807 is adapted to determine if the path message 803 contains protection information 40 indicating that protection switching is to be performed in one or more different layers of the multi-layer communication network, and if so, establish a protection switching mechanism in the one or more different layers using the protection information 40 provided in the path message 803.

摘要： A path computation element for a communications network, receives link advertisements from hybrid nodes (10) of the network and selects paths for new traffic flows based on the received link advertisements. The hybrid node has switching matrices (20, 30) operable using different protocols, and has internal links between the switching matrices. The link advertisements indicate a maximum and a minimum bandwidth on any one of the internal links for a new traffic flow. The element can select a path via the hybrid node for a new traffic flow according to the bandwidth of the requested new traffic flow and according to the maximum and the minimum bandwidth indicated by the link advertisements. Advertising the maximum and minimum bandwidths available for a single new traffic flow for the internal links can enable more efficient path computation with little additional cost and hence maintain scalability of the link advertisements for larger networks.
摘要翻译：一种用于通信网络的路径计算元件，从所述网络的混合节点（10）接收链路广告，并基于所接收的链路广告来选择用于新业务流的路径。混合节点具有可使用不同协议操作的切换矩阵（20,30），并且在切换矩阵之间具有内部链路。链路广告指示用于新业务流的任何一个内部链路上的最大和最小带宽。该元件可以根据所请求的新业务流的带宽并根据链路通告所指示的最大和最小带宽，通过混合节点为新的业务流选择路径。为内部链路的单个新流量流广告可用的最大和最小带宽可以实现更有效的路径计算，而且额外的成本更低，从而保持较大网络的链路广告的可扩展性。

摘要： According to a first aspect of the present invention there is provided a method of constructing an end-to-end routing path across multiple packet switched domains. The method comprises generating a domains topology identifying all possible domains, the border elements of those domains and the inter-domain links. When a request is received for computation of a path from a source entity in a first domain to a destination entity in a second domain, all domains and inter-domain links that cannot or are unlikely to feature in the requested path are removed from the domains topology. Candidate intra-domain paths for each remaining domain are then computed, witheach candidate intra-domain path being mapped to a logical link defined by its two ends, at least one end being a border element and the other being a border element or the source or destination entity.Attributes for each logical link are determined, together with attributes of the remaining inter-domain links. A virtual network topologyis generated by combining the logical links and their associated attributes with the remaining inter-domain links and their associated attributes. This allows a best end-to-end route to be determined by analysing the virtual network topology.
摘要翻译：根据本发明的第一方面，提供了一种跨多个分组交换域构建端到端路由路径的方法。该方法包括生成识别所有可能域的域拓扑，这些域的边界元素和域间链接。当接收到用于计算从第一域中的源实体到第二域中的目标实体的路径的请求时，从所述域中删除不能或不可能在所请求的路径中进行特征的所有域和域间链路拓扑结构。然后计算每个剩余域的候选域内路径，其中候选域内路径被映射到由其两端限定的逻辑链路，至少一端是边界元素，另一端作为边界元素或源或确定每个逻辑链路的属性以及剩余的域间链接的属性。通过将逻辑链路及其相关联的属性与剩余的域间链接及其相关联的属性组合来生成虚拟网络拓扑。这允许通过分析虚拟网络拓扑来确定最佳的端对端路由。

摘要： Aspects of the invention relate to a method (160) of adapting an association of physical resources in a network with a summarized resource (24) corresponding to one or more class of service. The method comprises monitoring at least one parameter of the summarized resources. The method further comprises comparing (164) the at least one parameter between a plurality of summarized resources, and comparing (164) the class of service of the summarized resources. Based on the comparing of the at least one parameter and based on the comparing of the class of service of the summarized resources, the method comprises determining (165) one or more summarized resources to be a source for providing physical resources and determining one or more summarized resources to be a destination for receiving physical resources. Based on the determining, the method comprises modifying (166) an allocation of physical resources to transfer an association of physical resources from the source summarized resource to the destination summarized resource.
