摘要:
A system and method for resolving a DNS request using metadata. An intelligent name server receives a request to resolve a domain name via a network. The intelligent name server acquires at least one metadata element about the source of the request. The domain name request is transformed into a CNAME request that includes the at least one metadata element and the domain name to be resolved. The CNAME request is sent to a metadata aware DNS server for resolution. The metadata aware DNS server maps the domain name to one or more network addresses stored in a look-up table. The included metadata is used to select a “best” host address to include in a response.

A mobile communication device initiates display of a point of interest as being located at particular coordinates on a map. In response to receiving an input command from a user of the mobile communication device indicating that the particular location of the point of interest as specified by the map is incorrect, the mobile communication device forwards a communication (specifying a location of the mobile communication device and an identity of the point of interest) over a network to a map management resource. Based on feedback from the mobile communication device, the map management resource updates map data an actual location of the point of interest as opposed to an incorrect location as specified by the particular coordinates on the map. Subsequent distribution of the updated map information from the map management resource specifies the proper coordinates of the point of interest in the geographical region.

A system and method for routing multicast packets. A multicast packet is received at an inbound interface on a switch/router. S,G data are obtained from the packet and used to search an OIL table. If the S,G data are found in the OIL table, the packet is forwarded on an outbound interface associated with the S,G data. If the S,G data are not found in the OIL table, the multicast routing table is consulted to obtain a longest match for the packet, and the packet is forwarded on the interface(s) which correspond to the longest match route. The multicast routing table may include a single entry, such that all packets that do not match an entry in the OIL are forwarded on the same outbound interface. The multicast routing table may include multiple entries with different covered ranges of (S,G).
摘要:
A first request, to access a web site associated with a domain name, is obtained at a gateway router interposed between a local area network and an internet service provider's infrastructure, from a host on the local area network. The gateway router has Domain Name Service (DNS) resolver capability. The first request is received while the gateway router has upstream connectivity to the internet service provider's infrastructure via IPv6 but not via IPv4. Further steps include sending, from the gateway router, the first request; obtaining, at the gateway router, an indication that an IPv4 address will imminently be required for the gateway router; and, responsive to obtaining the indication, sending, from the gateway router, into the internet service provider's infrastructure, a second request, for an IPv4 address for the gateway router.
