摘要： A method and apparatus for performing Layer 2 (L2) interworking is presented. A L2 Protocol Data Unit (PDU) is received at an L2 Switching Entity (SE). The L2 PDU is converted to a normalized Pseudowire (PW) PDU. The normalized PW PDU is then forwarded to a Layer 3 (L3) Routing Entity (RE). The normalized PDU may be in the form of a predetermined L2 protocol or a L2 agnostic protocol.

摘要： A method and apparatus for providing information in a network by way of a Pseudowire switching TLV is presented. A second device in the network receives a first message having information relating to a first device in the network. The second device appends information relating to the second device (by way of a Pseudowire switching TLV) to the first message, resulting in a second message. The second message is then forwarded to a third device in the network.

摘要： Systems, methods, and other embodiments associated with multiple NAT traversal are provided. A request is received from a host for a publicly-routable communication path identifier for the host, where the host is a member of a private network associated with a first network address translation device. The first network address translation device communicates with a second network address translation device using an address-port-borrowing-protocol to acquire information related to the publicly-routable communication path identifier. Information related to the publicly-routable communication path identifier is received with the first network address translation device and the publicly-routable communication path identifier is provided to the host.

摘要： In one embodiment, a method can include: receiving a packet in a device; classifying the received packet as a first packet type or a second packet type; when the packet is the first packet type, forwarding the packet to a next hop; and when the packet is the second packet type: performing forward error correction (FEC) encoding on the packet to generate repair data, modifying the packet by adding a multi-protocol label switching (MPLS) header to indicate that the packet is to be forwarded on an FEC-protected label switched path (LSP), generating an additional MPLS packet carrying the repair data, and forwarding the modified packet and the additional packet to a next hop.
摘要翻译：在一个实施例中，一种方法可以包括：在设备中接收分组; 将接收的分组分类为第一分组类型或第二分组类型; 当分组是第一分组类型时，将分组转发到下一跳; 并且当分组是第二分组类型时：对分组执行前向纠错（FEC）编码以产生修复数据，通过添加多协议标签交换（MPLS）报头来指示分组将被转发来修改分组在FEC保护的标签交换路径（LSP）上，生成携带修复数据的附加MPLS分组，并将修改的分组和附加分组转发到下一跳。

摘要： A method, apparatus and computer program product for routing data within a packet-switched network using a PW wherein the PW is terminated directly on the layer-3 routing device such that certain services and applications can be utilized is presented. The method, apparatus and computer program product receives an encapsulated layer-2 Protocol Data Unit (PDU) from a pseudowire emulating a service. The encapsulation is removed from the encapsulated layer-2 PDU and a layer-2 circuit associated with the pseudowire is terminated. The circuit is treated as an interface and the PDU is forwarded based on upper layer protocol information within the PDU.

摘要： A method, apparatus and computer program product for building multipoint Pseudo Wires (PWs) using Multicast Label Distribution Protocol (MLDP) is presented. A multipoint PW leaf identifier (mTAI) is configured on one or more Layer 2 (L2) leaf interface(s) of a multipoint PW. A multipoint PW root identifier identifying the root of the multipoint PW is also configured and an opaque value is computed, the opaque value used in MLDP label mapping messages that will flow upstream towards a the root of the multipoint PW. The opaque value is computed from the multipoint leaf identifier and the multipoint root identifier. The PE leaf routers direct MLDP label mapping to the root PE router via a core network.
