    Abstract: In one embodiment, a decapsulating network device receives a plurality of encapsulated packet fragments of an original packet, and decapsulates them into respective decapsulated packet fragments. The decapsulating network device caches an inner header of the original packet from one of the decapsulated packet fragments, and in response to caching the inner header, and for each particular decapsulated packet fragment as it is received and decapsulated: prepends the inner header and fragmentation information to the particular decapsulated packet fragment; and forwards the particular decapsulated packet fragment with the prepended inner header and fragmentation information from the decapsulating network device toward a destination of the original packet.

    Abstract: 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.

    Abstract translation: 提出了一种通过伪线切换TLV在网络中提供信息的方法和装置。 网络中的第二设备接收具有与网络中的第一设备有关的信息的第一消息。 第二设备将与第二设备相关的信息（通过伪线切换TLV）附加到第一消息，导致第二消息。 然后将第二个消息转发到网络中的第三个设备。

    IPC: H04L12/18

    Abstract: Methods, network devices and computer readable media are disclosed relating to a communication network. In one embodiment, a method includes receiving a message comprising a message bit array. The message bit array identifies egress nodes for the message within a bit indexed explicit replication (BIER) domain of a communications network. A first bit position in the message bit array represents a first one or more of the egress nodes, and a bit value at the first bit position indicates that the message is to be forwarded to one of the first one or more of the egress nodes. The method further includes accessing a first forwarding table entry corresponding to the first bit position, determining whether the first bit position is an anycast bit position having multiple corresponding forwarding table entries, and forwarding the message to one of the first one or more of the egress nodes.
