| 20090265541 | ADDRESSING AND ROUTING MECHANISM FOR WEB SERVER CLUSTERS - A method of establishing a Host Identity Protocol session between first and second Host Identity Protocol enabled hosts, where at least said second host is located behind a reverse-proxy. The method comprises providing the reverse-proxy with Diffie-Hellman public keying material of the second host, sending said Diffie-Hellman public keying material from the reverse-proxy to the first host as part of the Host Identity Protocol base exchange procedure, this material being bound to the Host Identity of the reverse-proxy for the purpose of the Host Identity Protocol session, and, at the first host, using the Host Identity of the reverse-proxy as the correspondent Host Identity for the Host Identity Protocol session, and, at the second host, using the Host Identity of the reverse-proxy as the originating Host Identity for the Host Identity Protocol session. | 10-22-2009 |
| 20100027465 | Delegation based mobility management - A method of handling mobility-related signaling in a communications system comprising a mobile node, a mobile router, and a peer node. The method comprises providing the mobile router with a delegation certificate that is cryptographically signed by or on behalf of the mobile node. At the mobile router, a mobility-related signaling exchange is initiated with the peer node on behalf of the mobile node, the mobile router providing to the peer node within this exchange, said delegation certificate or an identification of the certificate, and a sequence number associated with the certificate. At the peer node, the received sequence number is compared with a sequence number maintained by the peer node in respect of the delegation certificate, and the exchange authorised in dependence upon the result of the comparison. | 02-04-2010 |
| 20100097986 | Loop-Detection in Moving Networks - A method of generating network identifiers for use by mobile routers of a moving network is provided which enables fast and efficient routing loop avoidance and detection. The method comprises receiving at a mobile router of a sub-network chain, a beacon from a preceding mobile router in the chain, the beacon containing a network identifier of the preceding mobile router, generating a new network identifier by applying a pre-defined function to the received network identifier, and including the new network identifier in beacons broadcast by the receiving mobile router. When preparing for a handover, a mobile router compares the network identifier contained in a received beacon with values generated by applying said function against its own network identifier. This allows the mobile router to identify beacons originating from mobile routers that are downstream in the same chain. | 04-22-2010 |
| 20100106972 | SIGNALLING DELEGATION IN A MOVING NETWORK - In order to delegate location update signaling responsibility from a Mobile Node to a Mobile Router, the Mobile Router is provided with a second symmetric key generated by a Mobile Node using a first symmetric key shared between the Mobile Node and a Peer Node. The Mobile Router is additionally provided with a “certificate” authenticating the second symmetric key using the first symmetric key. In this way, the mobile router can sign location update related messages sent to the Peer Node with the second symmetric key, and can provide the Peer Node with the certificate in order to allow the Peer Node to authenticate the right of the Mobile Router to act on behalf of the Mobile Node. | 04-29-2010 |
| 20100303072 | Multicast Source Mobility - A method of delivering an IP multicast stream from a source node to a destination node. The method comprises establishing a Host Identity Protocol association between a multicast router and at least one further network node upstream of the multicast router, both of which are present in the multicast path, and using said association(s) to transport multicast packets. | 12-02-2010 |
| 20110055570 | LOCATION UPDATE OF A MOBILE NODE - A method of facilitating location update signalling within a communication network between a mobile node and an end host includes establishing a trust relationship between one or more end hosts ( | 03-03-2011 |
| 20110149973 | Packet Forwarding In A Network - A method of providing packet routing information comprises: encoding routing information from a source node to one or more destination nodes into a compact representation of set membership; and putting the compact representation of sets into a header of a packet that is to be sent from the source node to the destination node(s). The compact representation may be obtained by: generating d representations of a set of identifiers; generating d candidate compact representations of set membership from the d representations of the identifiers; and selecting one of the candidate compact representation of set membership. The selection may be made on the basis of which of the candidate compact representations has the lowest rate of returning false positives. | 06-23-2011 |
| 20110296027 | HOST IDENTITY PROTOCOL SERVER ADDRESS CONFIGURATION - A method of facilitating access to a Host Identity Protocol security procedure by a host connected to a moving network, where the moving network comprises a Host Identity Protocol server responsible for allocating local IP addresses to attached hosts. The method comprises registering at a rendezvous server an IP address prefix for use by said Host Identity Protocol server in allocating said local addresses, together with an externally reachable IP address of the Host Identity Protocol server. The registered IP address prefix is used at the rendezvous server to forward received I | 12-01-2011 |
