Abstract: Traffic is transferred between a first consumer network node and a second consumer network node via a local connection established at a first service provider network node. The first service provider network node is connected to the first consumer network node via a first attachment circuit, and to the second network consumer node via a second attachment circuit. A loss in connectivity is detected between the first consumer network node and the second consumer network node via the local connection, and in response, traffic is transferred between the first consumer network node and the second consumer network node via a remote connection. The remote connection includes a pseudowire established between the first service provider network node and a second service provider network node. The second consumer network node is connected to the second service provider network node via a third attachment circuit.

Abstract translation: 通过在第一服务提供商网络节点处建立的本地连接，在第一消费者网络节点和第二用户网络节点之间传送业务。 第一服务提供商网络节点经由第一附接电路连接到第一用户网络节点，并经由第二附件电路连接到第二网络消费者节点。 经由本地连接在第一用户网络节点和第二用户网络节点之间检测到连接性的损失，并且作为响应，经由远程连接在第一用户网络节点和第二用户网络节点之间传送流量。 远程连接包括在第一服务提供商网络节点和第二服务提供商网络节点之间建立的伪线。 第二用户网络节点经由第三连接电路连接到第二服务提供商网络节点。
