摘要： A method and system are provided for connecting at least three provider peer elements PEs located in two L2 network sites, via a provider network, wherein at least in one of the L2 sites and two of the provider peer elements PEs are connected to a customer equipment CE forming together a dual homing structure. The method and system are characterized in that they rely on the use of only a single PW in the provider network that extends between PEs of the two L2 network sites while ensuring traffic protection for the PW in the provider network, and ensuring that in case of a failure of one of the PEs or its connection to the customer equipment at one of the sites, the other L2 network site remains unaware of the failure, so that once established, traffic communication over the PW is maintained like no failure has happened.

摘要： A method for providing a protected fast rerouting scheme for traffic conveyed in a network comprising a working path and a first backup path for conveying the traffic in case of a node failure. The method enables conveying traffic when two simultaneous failures occur, a failure of a link and/or of a node, belonging to the working path and the other—a failure occurring at a link and/or a node belonging to the first backup path. Upon detecting occurrence of a link/node failure along the working path, traffic is diverted to the first backup path, and upon detecting a concurrent failure at the downstream link/node at the first backup path, traffic is diverted to a second backup path extending from a node belonging to the first backup path and merges with the working path at a node located downstream of the failure that occurred at the working path.
摘要翻译：一种用于为在网络中传送的业务提供受保护的快速重新路由方案的方法，包括工作路径和用于在节点故障的情况下传送业务的第一备份路径。当发生两个同时发生的故障，属于工作路径的链路和/或节点的故障，另一个故障发生在属于第一备份路径的链路和/或节点时，该方法能够传送流量。当检测到沿着工作路径的链路/节点故障的发生时，流量被转移到第一备份路径，并且在检测到在第一备份路径处的下游链路/节点处的并发故障时，流量被转移到第二备份路径延伸来自属于第一备份路径的节点，并且在位于在工作路径发生的故障的下游的节点处与工作路径合并。

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.
摘要翻译：提供了一种用于管理分组交换机中的业务拥塞的方法，其包括以下步骤：在交换机处提供两个以上不同的拥塞级别，以处理与至少两个不同优先级相关联的业务，一个是低优先级业务，另一个高优先级流量; 对于具有特定目的地和优先级的每个业务流，确定与从多于两个拥塞控制级别中选择的拥塞控制级别匹配的当前拥塞级别，并且关联用于处理每个相应业务流的不同操作集合，依赖在其优先级和其当前拥塞水平以及针对每个业务流的情况下执行与相应的相关联的一组操作相匹配的操作，并且其中对于每个相应业务流执行这些操作的速率在发生较高拥塞水平时增加各自的交通流量。
