摘要:
The present invention provides methods and apparatus for including geographical information of a target node in a geographical response message when requested by a requesting node. Geographical messages are supported at higher layer protocol. The geographical messaging may be included in an IPv6 datagram that supports a data payload and the geographical information in an extension header. An embodiment of the invention supports messaging that is associated with the Internet Control Message Protocol (ICMP) and that is compatible with IPv6 specifications. The requesting node may insert the geographical position of the requesting node when sending a request to the target node. Both peer-to-peer and client-server architectures may be supported. A node may provide geographical-based information that comprises geographical coordinates or other variations of the geographical-based information. Moreover, a node may include non-geographical information that is associated with the node.
