terence

By far , microsoft ’ s teredo is the only tunnel mechanism that supports nat users in a certain extent , but meanwhile has many limits such as not supporting symmetric nat , not being able to provide bidirectional ipv6 connections , having poor security , etc . silkroad exploits the client - server tunnel mode and makes use of the stateful characteristic of tunnel servers to resolve the teredo ’ s problems 目前已有的隧道機制中,只有微軟公司提出的teredo協議在一定程度上支持nat 。然而, teredo實際上不能為nat用戶提供雙向的端到端ipv6連接,不支持對稱類型的nat ,并且存在安全隱患。 silkroad采用客戶端-服務器模式的系統結構,利用隧道服務器的有狀態特性,解決了teredo存在的問題。
