| Abstract: | ISATAP is one kind of important IPv6 transition technology. The ISATAP principle is introduced and several kinds of main automatic tunneling is compared. The advantages and disadvantages of ISATAP based on explanation are summarized. Intra-site ISATAP hosts are unable directly to pass through NAT and communicate with other extra-site ISATAP hosts. One resolution of ISATAP which can pass through NAT by translating IPv4 address and IPv4 address simultaneity is proposed. Using this resolution, ISATAP hosts in differ sites can communicate successfully. |
