    摘要： The present invention relates to a Domain Name System (DNS) server and a method for resolving DNS queries from a number of clients. The DNS server comprises multiple virtual DNS server instances servicing different clients. The DNS server further comprises a shared cache for caching records which indicate answers to resolved DNS queries. The shared cache is shared between a set of virtual DNS server instances. The virtual DNS server instances that share the shared cache are able to cache DNS query results in the shared cache as well as resolve a DNS query by retrieving a cached record corresponding to the DNS query from the shared cache. Thus it is possible for a virtual DNS server instance to make use of DNS query results obtained by other virtual DNS server instances.

    摘要： A method of routing traffic between external users and a communication network via a private access network. The method comprises establishing a secure outer tunnel between the private network and a gateway of a public access network to which the private network is coupled, based upon authentication of the private network to the public access network, said gateway being coupled to said communication network. For each external user wishing to connect to the communication network via the private network, a secure inner tunnel is established between the user and the gateway based upon authentication of the user to the gateway, the inner tunnel being within said outer tunnel. Traffic is caused to flow between external users and the gateway through the respective inner tunnels.

    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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 I1 messages to the Host Identity Protocol server. The rendezvous server controls the allocation and registration of address prefixes to Host Identity Protocol servers in order to prevent collision of local IP addresses.

    摘要： 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 (1) and a proxy (3). When a mobile node (2) is handed-off, a location update is performed between the mobile node (2) and the proxy (3), and a location update message is sent from the proxy to the end host(s) having the trust relationship with the proxy. Multiple end hosts may authorise the same proxy to perform location update signalling on their behalf. The number of signalling messages required to perform the location update may be reduced, compared to a legacy method in which the mobile node is required to perform location update signalling with each end host.
