Abstract
The invention discloses a method for establishing the network address translation (NAT) traversal path of a peer-to-peer (P2P) connection, and relates to the selection of a traversal full path between one client and another peer-to-peer network client. The method comprises the steps of S10, selecting an unchecked address of highest priority in a to-be-checked address list as a current checking path; S20, according to the current checking path, sending a path checking request message to another peer-to-peer network client; S30, monitoring the NAT host of a local client; S40, judging whether the NAT host of the local client receives the path checking request message sent by the other peer-to-peer network client or not; S50, on the condition that the local client receives the path checking request message sent by the other peer-to-peer network client, setting the current address as an optimal path; S60, stopping the checking cycle.
Description
Technical field
The present invention relates to communication technical field, particularly relate to method for building up, Apparatus and system that a kind of P2P connects the path that NAT passes through.
Background technology
Because each transmission terminal may be positioned at public network in the application of current P2P (point-to-point transmission), after also may being positioned at various types of NAT, therefore needing to realize dissimilar NAT for various situation and pass through.
ICE (interactive connection establishment) has been acknowledged as NAT traversal scheme first-selected under all NAT environment at present, ICE itself is a kind of framework just, its integrated application STUN, the agreements such as TURN provide a general solution, NAT is passed through work in most suitable situation, to make up the inherent shortcoming being used alone wherein any one and bringing.
But pass through in mechanism at the NAT of ICE, need to collect all possible path, then sort to all paths according to priority, finally according to priority order checks all paths, thus looks for most suitable path for transmission.
When current NAT passes through, the method for Path selection is: check all paths of collecting according to the priority orders sequenced separately, pick out satisfactory path, finally selects the highest path of priority to use.The shortcoming of this method has: asynchronous when one, both sides check path, and a such as side is checking the path of a certain priority, and the other side is not in the route inspection request of monitoring this priority, will cause checking overtime and failed like this; Two, routing algorithm design is bad, the facility that the priority not making full use of path is brought, since all paths are all sort according to priority, so according to priority checking from high in the end, can be optimal path with just determining once be checked through path.
