Description
Technical field
The present invention relates to communication technical field, relate in particular to method and apparatus and system that a kind of packet mistake is handled and controlled.
Background of invention
Present computer network communication, transfer of data mainly are to realize by Internet (Internet), World Wide Web (WWW), the Internet TCP/IP protocol suite, comprise the Internet Control Message Protocol (ICMP, ICMPv6) of IPv4, IPv6 etc., and by router, gateway many computer networks in the world wide are linked together, become current maximum and most popular data communication network.The foundation of Internet and successful development, and being extensive use of of World Wide Web (WWW), for people's life has brought huge change, Internet and World Wide Web (WWW) have had influence on the every aspect of society.But also there are its limitation and weak point in Internet, World Wide Web (WWW).
Present the Internet is (to comprise and use router with communication apparatus, gateway) and transmission medium will be distributed in diverse geographic location function independently computer system link together, and by comprising IPv4 with TCP/IP protocol suite or/and the Internet Control Message Protocol (ICMP of IPv6, ICMPv6), realize the Report of Discrepancy of the IP protocol data grouping in the network communication process, well-known the Internet realizes that the basis of transfer of data is a TCP/IP protocol suite, present Internet Control Message Protocol (ICMP, ICMPv6) be one of core protocol in the TCP/IP protocol suite, and the core of TCP/IP technology is the IP address, as the IPv4 address, the IPv6 address, be that main frame of IP address designation and network one of usefulness is connected be interface, to realize the communication of host-to-host.The simple IPv4 of functional structure address, IPv6 address and other identifier as the age knot of keeping records by tying knots, are a mark at present.Between the IP address, and do not define mutual incidence relation between the isomery identifier, do not define the overall situation of IP address and local location, Virtual Space, do not define Virtual Space structure, the logical relation of identifier, all do not relate to Virtual Space a kind of overall situation, unified structure is carried out and the definition that is mutually related in the IP address, and be the Virtual Space various resource construction overall situations, the unified structure that is identified and the standard that is mutually related by the IP address.Therefore existing various IP address all is relatively independent one by one identifier, the IP address of present identifying resource can not build the overall situation for the object that is identified, unified Virtual Space structure (logical network) with interrelated relation, corresponding IPv4, IPv6, (the ICMP of Internet Control Message Protocol separately among the IPv9, ICMPv6) can and not relate to about with a kind of identifier with Virtual Space structure yet---the logical network of multi-dimensional address definition, and the resource of representing with multi-dimensional address, the packet mistake of carrying out in physical network that route resource constitutes and/or the logical network is handled and control.
About present Internet Control Message Protocol (ICMP, ICMPv6), in [RFC2463, Internet standard], [RFC792, Internet standard], be documented.
