摘要：Techniques are disclosed for generation of spanning trees that support

provision of performance-guaranteed services over a circuit-switched network such as, forexample, an optical-based network. For example, a technique for generating a spanningtree for use in forwarding Ethernet-based data in a circuit-switched network comprisesthe following steps/operations. Input information is obtained. The input informationcomprises a representation of the network, a set of Ethernet-enabled nodes in thenetwork, and a set of demands. A spanning tree is computed based on at least a portionof the input information such that the spanning tree substantially satisfies one or moreperformance requirements (e.g., one or more bandwidth requirements) associated withthe set of demands. Advantageously, in one embodiment, such techniques may providefor generation of spanning trees for use in supporting bandwidth-guaranteed Ethernetservices such as E-LAN over a SONET (and SDH) network.
