    • A system and method for protection of virtual connections at the data link layer. The method provides for protection switching in a ring network. The method comprises detecting an error in one of a first and second routes (“the errored route”). Error cells are generated for each virtual connection affected by the detected error. Error cells are transmitted downstream on the errored route. First switch fabric receives the error cells at a downstream network element associated with the errored route. Change in state of the errored route is communicated to a second switch fabric of the downstream network element associated with the other of the first and second routes (the “other route”). When the state of the errored route is worse than the state of the other route, automatically configuring the second switch fabric to establish the other route to be a working route for the virtual connection.
    • 用于保护数据链路层虚拟连接的系统和方法。 该方法提供环网中的保护倒换。 该方法包括检测第一和第二路由(“错误路由”)之一中的错误。 为检测到的错误影响的每个虚拟连接生成错误单元。 错误单元在错误路由下传输。 第一交换结构在与错误路由相关联的下游网元处接收错误信元。 错误路由的状态的改变被传送到与第一和第二路由中的另一个(“其他路由”)相关联的下游网元的第二交换结构。 当错误路由状态比其他路由状态更差时,自动配置第二交换机结构,建立另一条路由,作为虚拟连接的工作路由。

    • A method for controlling virtual connections between endpoints over a unidirectional ring network. The network includes a number of network elements coupled together to form segments of the ring network. The method receives a request to create a virtual connection between first and second endpoints on the ring network. The method identifies the segments of the ring network that would be affected by the addition of the connection between the first and second endpoints. Further, the method retrieves data that represents the currently allocated capacity for each affected segment. For each affected segment, the method determines whether adding the requested virtual connection would exceed the capacity for the segment. The method transmits signals over the ring to establish the virtual connection when adding the virtual connection does not exceed the capacity for any of the affected segments.
    • 一种用于通过单向环网控制端点之间的虚拟连接的方法。 网络包括耦合在一起以形成环网的段的多个网元。 该方法接收在环形网络上的第一和第二端点之间创建虚拟连接的请求。 该方法识别将由第一和第二端点之间的连接添加而影响的环网的段。 此外,该方法检索表示每个受影响的段的当前分配的容量的数据。 对于每个受影响的段,该方法确定是否添加请求的虚拟连接将超过该段的容量。 当添加虚拟连接不超过任何受影响的段的容量时,该方法通过环发送信号以建立虚拟连接。

    • A network element for a virtual path ring network is provided. The network element includes a first ring interface module with a ring input and a ring output. Further, the network element includes a second ring interface module with a ring input and a ring output. A first bus is coupled to the first ring interface. A second bus is coupled to the second ring interface. The first and second ring interface modules each include a switch fabric that passes packets from the ring input of the interface module to its ring output for packets with a destination address for an endpoint associated with another network element. The switch fabrics of the first and second ring interfaces further pass packets from the ring input to the first and second buses, respectively, for packets with destination addresses for endpoints that are associated with the network element. An access interface module is coupled to the first and second buses that adds and drops traffic to and from the ring network.
