Background technology
Teredo be an IPv6 to the IPv4 switch technology, when IPv6 or IPv4 main frame are positioned at after one or more IPv4 network address translation (nat)s, be used for providing automatic tunnel between address assignment and main frame for clean culture IPv6 connects.IPv6 data flow from the Teredo main frame sends with the IPv4UDP data format, and when NAT supported that udp port is resolved, the Tered data flow can be passed through NAT.
NAT device lacks IPv6 to IPv4 function and multi-layer NAT allocation problem to Teredo by realizing solving now in IPv6 packet tunnel between the main frame in website, and IPv6 is to the tunnel between the IPv4 use edge device.The IPV4 header of protocol domain was set at 41 when the tunnel had brought the IPv6 packet of another one problem: IPv4 compression to send to NAT between the main frame, but the parsing of agreement 41 is not the general utility functions of NAT, so the IPv6 communications of IPv4 compression can not be passed through general NAT.In order to make the IPv6 transfer of data can pass through single or multi-layer NAT, the IPv6 packet must be compressed into the data of IPv4UDP form, comprises each one of IPv4 and UDP header.UDP message generally can be resolved by NAT and can be passed through multi-layer NAT.
Network address translation (nat) is meant the IPv4 router that meets RFC 1631 standards, it can be before transmission resolution data bag IP address and TCP/UDP port numbers.The type of NAT has:
(Cone) NAT fully: be meant a class NAT who in nat translation table, has stored mapping relations between home address and port numbers and external address and the port numbers.One nat translation table is started working, and all will be converted from the inbound data bag of any source address and port opens into external address and port.
Limited NAT: no matter refer to store in nat translation table the mapping between home address and port numbers and external address and the port numbers, be specific source address or particular source and port numbers.If coincide to the inbound data bag and the nat translation table of external object address and port from certain unknown external address or port, this data flow will be abandoned automatically so.
Symmetry NAT: refer to identical home address and port numbers are mapped to the different external addresss and the NAT of port numbers according to external object address (being applicable to the outbound data bag).
For existing IPv6 transition protocol Teredo, only support taper NAT and restriction NAT, can not support reciprocity NAT, this has limited the deployment of Teredo technology in particular network environment.
