    • In one example embodiment, a system and method is provided that includes establishing a plurality of Pseudo Wire (PW) connections between a first network appliance region and a second network appliance region to transmit data from the first network appliance region to the second network appliance region along an active PW. Further, the method includes disabling the active PW when a failure of the active PW is detected. Additionally, the method may include selecting an inactive PW to become a new active PW such that the data may be transmitted from the first network appliance region to the second network appliance region. Moreover, the method includes switching from the active PW to the new active PW.
    • 在一个示例实施例中,提供了一种系统和方法,其包括在第一网络设备区域和第二网络设备区域之间建立多条伪线(PW)连接,以将数据从第一网络设备区域传输到第二网络设备区域 沿着主动PW。 此外,该方法包括当检测到活动PW的故障时禁用活动PW。 此外,该方法可以包括选择不活动的PW以成为新的活动PW,使得数据可以从第一网络设备区域发送到第二网络设备区域。 此外,该方法包括从主动PW切换到新的主动PW。
