    Abstract: A method and nodes are provided for localizing traffic between communication nodes receiving service from a same network. A local mobility anchor informs media access gateways providing access to two communication nodes of each other's addresses. Traffic exchanged between the two communication nodes connected to the same network via these media access gateways are routed directly between the gateways, bypassing the local mobility anchor.

    Abstract: Reduction of overhead normally caused by the addition of a second IP header in case of tunneling between a home agent and a mobile node located in a foreign network is achieved by replacing an encapsulated first IP header by a tunnel identifier. The home agent and the mobile node agree on a tunnel identifier value at the time of binding update and acknowledgement. The tunnel identifier may be used independently at the home agent and at the mobile node to reconstruct the first IP header, which identifies a correspondent node. Because the encapsulated first IP header is not terminated at either of the home agent or mobile node, overhead reduction is not impacted by eventual transmission error or loss between these two nodes.

    Abstract translation: 通过在归属代理和位于外部网络中的移动节点之间的隧道的情况下通过添加第二IP报头而引起的开销的减少是通过用隧道标识符替换封装的第一IP报头来实现的。 归属代理和移动节点在绑定更新和确认时同意隧道标识符值。 隧道标识符可以在归属代理和移动节点处独立地使用，以重建标识通信节点的第一IP报头。 由于封装的第一个IP报头没有在归属代理或移动节点的任何一个终止，所以开销降低不会受到这两个节点之间的最终传输错误或丢失的影响。

    Abstract: Methods, network address translation (NAT) devices, network nodes and system for allowing identification of a private device in a public network or treating traffic of a private device in a public network. The NAT may allocate a private IPv4 address to the private device, reserve a block of ports on the public IPv4 address for the private device and send an identification of the block of ports to a network node in the public network. The network node of the public network may receive an identification of a block of ports on the public IPv4 address indicating that the block of ports is reserved for the private device and activate a rule for treating traffic of the private device.

    Abstract: Methods, a data source and a router are provided to fragment packets that are to be sent in multicast mode towards a plurality of destinations comprised in a multicast group. Each router along a path leading from the data source towards some of the destinations sends its maximum transmission unit value in an uplink direction. Each router directly connected to the data source calculates a lowest maximum transmission unit based on various maximum transmission unit values received from downstream routers. The data source receives from each of the directly connected routers a maximum transmission unit value, which is certain to be acceptable to all routers and destinations of the multicast group downstream of that directly connected router. The data source selects a lowest one of the received maximum transmission unit values and fragments data contents accordingly.

    Abstract translation: 提供了一种数据源和路由器，用于将要以组播模式发送的分组分段到组播组中包含的多个目的地。 沿着从数据源朝向某些目的地的路径的每个路由器在上行链路方向上发送其最大传输单元值。 直接连接到数据源的每个路由器基于从下游路由器接收的各种最大传输单元值计算最低最大传输单元。 数据源从每个直接连接的路由器接收最大传输单元值，该最大传输单元值对于直接连接的路由器下游的多播组的所有路由器和目的地是可接受的。 数据源选择接收到的最大传输单元值中的最低一个并相应地分段数据内容。
