摘要： 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.
摘要翻译：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。

摘要： A lattice of interconnected concepts is constructed from flow entries. Each concept describes a subset of flows and a subset of the flow attributes. Based on user queries, the lattice is used to build disjoint sets of flows referred to as flowsets. Each user query specifies one or more of the flow attributes to be measured. Each flowset includes one or more of the flows to thereby enable sharing of the hardware counters among the flows. One hardware counter is then assigned to each flowset.

摘要： A method and packet switched cellular telecommunication system wherein data flows from a terminal are aggregated into one or more Multi Protocol Label Switching (MPLS) Label Switched Path (LSP) based on at least one criterion. In a first embodiment, the data flows are aggregated into LSP(s) based on a Quality of Service (QoS) class of each such data flows, by a Network Node, such as a Radio network Controller (RNC) or a Serving GPRS Support Node (SGSN). In a second embodiment, the data flows or LSPs are aggregated into another LSP(s) based on the destination routing area. The LSP aggregation is performed by an Edge Node of the routing area, such as a Gateway GPRS Support Node (GGSN). In a first variant of the 2nd embodiment, the aggregation is used for macro-mobility, while in yet another variant the same aggregation is used for defining a virtual private network.

摘要： A system, a method and a Mobile Node (MN) for enabling a handover of the MN from a current serving access router (PAR) to a next serving access router (NAR) in a data communications network. At least one tunnel is present between the PAR and the NAR to enable data exchange therebetween. The MN has a first address valid under the PAR and is capable of forming a second address valid under the NAR prior to completion of the handover. The MN sends a handover request to the PAR and proceeds with a connection to the NAR without discarding its first address. The MN then completes the handover towards the NAR and receives traffic sent on the first address from the NAR.
