摘要： A method is provided for managing congestion of traffic in a packet switch, which comprises the steps of: providing more than two different congestion levels at the switch for handling traffic associated with at least two different priorities, one being a low priority traffic and another being a high priority traffic; for each traffic flow having a specific destination and priority, determining a current congestion level that matches a congestion control level which is selected from among the more than two congestion control levels, and associating a different set of operations for handling each respective traffic flow, depending on its priority and its current congestion level, and for each traffic flow, performing operations that match the respective associated set of operations, and wherein a rate at which these operations are performed for each respective traffic flow increases when a higher congestion level occurs at that respective traffic flow.

摘要： A method is disclosed for provisioning loop free H-VPLS traffic service in a multi-domain MPLS network having interconnected domains. The method comprises: provisioning pseudo wires (PWs) for MPTMP services in each domain of the MPLS network; defining multiple Split Horizon Groups (SHGs) in the network, wherein each SHG corresponds to a domain, for the H-VPLS service traffic and for each specific node of the MPLS network, automatically assigning indications to SHG and the pseudo wires connected to the specific node, wherein the same indication is assigned to all pseudo wires belonging to the same group (SHG-N), and wherein the step of assigning is characterized in that when traffic belonging to H-VPLS service crosses a border network node located between two interconnected domains, the SHG-N indication of PWs remains the same within a VPLS domain thereby preventing the service traffic from returning to the domain of origin.
摘要翻译：公开了一种在具有互连域的多域MPLS网络中提供无循环H-VPLS业务服务的方法。该方法包括：在MPLS网络的每个域中为MPTMP业务提供伪线（PW）; 在网络中定义多个分裂视野组（SHG），其中每个SHG对应于域，对于H-VPLS服务业务，并且对于MPLS网络的每个特定节点，自动分配指示给SHG和连接到特定的节点，其中相同的指示被分配给属于同一组（SHG-N）的所有伪线，并且其中所述分配步骤的特征在于，当属于H-VPLS服务的业务跨越位于两个互连的边界网络节点域中，PW的SHG-N指示在VPLS域内保持相同，从而防止服务流量返回到原始域。

摘要： A method is described for providing an MPLS tunnel adapted for sharing bandwidth (BW) in an MPLS network. The method comprises establishing the MPLS tunnel as a working MPLS tunnel (ST) to be shared by a plurality of pseudo wires (PWs) passing at least partially along the path of the tunnel ST, wherein a predetermined bandwidth of the bandwidth allocated for the ST is adapted to be shared by the plurality of PWs, of which at least one PW has a different source point and/or a different destination termination point at the ST path, from at least one other of the plurality of PWs.
