摘要： Embodiments of the invention relate to a method (400) for routing traffic through a network having a plurality of nodes, at least one of said plurality of nodes being an integrated node including first and second technologies integrated inside the same node platform, the method comprising: applying (402) a transformation algorithm to the plurality of nodes for determining at least one virtual link between at least two ports of the plurality of nodes; and performing (404) a routing algorithm using the at least one virtual link to determine an optimal virtual route for the traffic through the network based on at least one cost parameter associated with the at least one virtual link. By applying a transformation algorithm to a plurality of nodes in a network, virtual links can be created between virtual ports in the nodes, which are homogenous and allow all routes through the network to be considered concurrently during a routing algorithm. This allows an optimal route to be determined based on cost parameters associated with each virtual link.
摘要翻译：本发明的实施例涉及一种用于通过具有多个节点的网络路由业务的方法（400），所述多个节点中的至少一个节点是包括集成在同一节点平台内的第一和第二技术的集成节点，所述方法包括：：向所述多个节点应用（402）变换算法以确定所述多个节点中的至少两个端口之间的至少一个虚拟链路; 以及使用所述至少一个虚拟链路执行（404）路由算法，以基于与所述至少一个虚拟链路相关联的至少一个成本参数来确定通过所述网络的流量的最优虚拟路由。通过对网络中的多个节点应用变换算法，可以在节点中的虚拟端口之间创建虚拟链路，这些链路是同质的，并且允许在路由算法期间同时考虑通过网络的所有路由。这允许基于与每个虚拟链路相关联的成本参数来确定最优路由。

摘要： Routing traffic across a network having an optical layer (40) and an electrical layer (30), involves using a common topology representing the optical and electrical layers of the network. The common topology is such that an individual port of a respective optical device in the optical layer (40) is represented as corresponding virtual nodes (145), coupled by virtual links (155), in the common topology together with a representation of nodes and links of the electrical layer. The routing path in terms of the common topology is mapped back into a routing path through the actual optical devices (50) of the optical layer. By moving the handling of colour (including wavelength assignment, wavelength continuity and colour selection where it is tunable/selectable) and direction constraints to the preliminary step of creating the common topology, the routing process can be simplified.
摘要翻译：跨越具有光学层（40）和电层（30）的网络的路由业务涉及使用表示网络的光层和电层的公共拓扑。公共拓扑结构使得光层（40）中的相应光学设备的单独端口被表示为在公共拓扑中与虚拟链路（155）耦合的对应虚拟节点（145）以及节点的表示，以及电层的链接。根据公共拓扑的路由路径通过光层的实际光学设备（50）映射回到路由路径中。通过移动颜色处理（包括波长分配，波长连续性和可调/可选择的颜色选择）以及方向约束到创建公共拓扑的初步步骤，可以简化路由过程。
