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: A method and a node for establishing a tunnel with a set of minimal characteristics with a second node in a network. The node comprises a tunneling protocol module that determines a first set of desired characteristics and comprising a sub-option indicating a need for an authentication characteristic. The tunneling protocol module sends a tunnel request message comprising the first set of characteristics and sends a shared secret key with an index value thereof. The tunneling protocol module receives a tunnel reply message comprising a second set of desired characteristics determined by the second node and verifies if the second set of characteristics is at least equal to the set of minimal characteristics. If so, the tunneling protocol module sends a tunnel acknowledgment message. The shared secret is used to encrypt data and the index value indicates that the shared secret is used to encrypt the data.

Abstract: 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.

Abstract: A Radio Network Server (RNS) is modified to function as a policy server providing radio network resource allocation rules in an integrated third generation wireless IP network. The RNS determines a level of availability of radio network resources, and determines whether the level is sufficient to satisfy requests for resources in accordance with policy rules. The RNS informs a Bandwidth Broker (BB) whether the radio network resources are available. The BB functions as a Policy Decision Point (PDP) for its domain, and either allows or denies requests from users for network resources based on the input from the RNS. A plurality of edge routers in each domain interface with the BB utilizing the Common Open Policy Service (COPS) protocol interface. The edge routers function as Policy Enforcement Points (PEPs) for their domain to enforce policy decisions made by the BB. The BB may interface with BBs in other domains for calls that span multiple domains.

Abstract: A method and a router having a plurality of blades comprising at least a first blade and a second blade. The router comprises an interconnect providing a plurality of channels, each of which being used between two of the blades. The first blade receives a packet addressed to exit the router via the second blade, segments the packets into at least two fragments and forwards each fragment to at least two different blades, each via one of the interconnect's channels. The interconnect may be an optical interconnect by which a single wavelength from one blade defines one of the plurality of channels and wherein each blade supports a plurality of wavelengths. The at least two different blades may comprise each blade of the router, except the first blade. Each of the plurality of channels may also be a dedicated channel between two of the blades.

Abstract: 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.
