摘要： An existing protection mechanism is enhanced through the use of an automatic protection switching protocol data unit (APS PDU). In conjunction with transmitting Ethernet frames to a second bridge over a primary path, a first bridge transmits APS PDUs to the second bridge over a secondary path. The APS PDUs provide the second bridge with information about the protection switching mechanism being used and provide indications regarding the status of the primary path. In particular, protection switching may be facilitated by forming an APS PDU that is extended to include an indication of an identity for a trunk or a primary path before transmitting the APS PDU to the second bridge. Alternatively, after forming a regular APS PDU, protection switching may be facilitated by encapsulating the regular APS PDU with information identifying a trunk or a primary path before transmitting the APS PDU to the second bridge.
摘要翻译：通过使用自动保护切换协议数据单元（APS PDU）来增强现有的保护机制。结合在主路径上向第二桥发送以太网帧，第一桥将辅助路径上的APS PDU发送到第二桥。 APS PDU向第二个网桥提供有关正在使用的保护倒换机制的信息，并提供有关主路径状态的指示。特别地，可以通过形成在将APS PDU发送到第二桥之前扩展以包括中继线或主路径的标识的指示的APS PDU来促进保护倒换。或者，在形成常规APS PDU之后，可以通过在将APS PDU发送到第二桥之前封装具有标识中继线或主路径的信息的常规APS PDU来促进保护倒换。

摘要： Described are a network, network device, and method for a method of distributing routing information for a virtual private network (VPN) application through a packet-switched network (PSN) having fully meshed provider edge (PE) routers through Provider Backbone Bridge (PBB) tunnels. Each PE router is configured to support at least one VPN and to run a BGP (Border Gateway Protocol) as an auto-discovery process for finding one or more other PE routers attached to the same VPN. A given VPN is associated with a PBB tunnel. A service instance identifier (I-SID), as defined in IEEE 802.1ah, is assigned to the VPN. Each PE router advertises membership in the VPN by including the I-SID assigned to the VPN in a BGP message issued during the auto-discovery process.

摘要： Frames of customer traffic may be encapsulated by adding Mac-in-Mac (MiM) encapsulation fields for transportation of the frames over a portion of provider network. The MiM encapsulated traffic may be further encapsulated using VPLS by adding VPLS encapsulation fields for transportation of the frames over another portion of the provider network. The MiM encapsulations use provider network MAC addresses which enables VPLS MAC learning to occur using provider network MAC address space. MiM tunnels are mapped to VPLS service instances which are assigned pseudowire tags for transportation over the VPLS portion of provider network. The MiM header is retained when the MiM encapsulated frames are transported over the VPLS portion of the provider network. As VPLS frames exit the core network, the VPLS encapsulation fields are removed to extract the original MiM encapsulated frames for further transportation over the MiM portion of the provider network.
摘要翻译：客户流量的框架可以通过添加Mac-in-Mac（MiM）封装字段来封装，用于在提供商网络的一部分上传输帧。可以使用VPLS进一步封装MiM封装的流量，通过添加用于在提供商网络的另一部分上传输帧的VPLS封装字段。 MiM封装使用提供商网络MAC地址，使得可以使用提供商网络MAC地址空间进行VPLS MAC学习。 MiM隧道映射到VPLS服务实例，VPLS服务实例被分配伪线标签，用于通过供应商网络的VPLS部分进行传输。当MiM封装的帧通过提供商网络的VPLS部分传输时，MiM头部被保留。由于VPLS帧离开核心网络，VPLS封装字段被删除，以提取原始的MiM封装帧，以便在提供商网络的MiM部分进一步传输。
