Abstract:
1. A method for acquiring a network address translation (NAT) traversal resource, comprising: generating, by a peer to peer (P2P) entity, a message carrying a request for collecting an NAT traversal resource, and sending the message carrying the request for collecting the NAT traversal resource to a destination P2P node; collecting, by a middle P2P node and the destination P2P node receiving the message carrying the request for collecting the NAT traversal resource, the NAT traversal resource; and sending, by the middle P2P node and the destination P2P node, the collected NAT traversal resource to a first P2P node wherein the sending, by the middle P2P node and the destination P2P node, the collected NAT traversal resource to the first P2P node further comprises: adding, by the middle P2P node, the collected NAT traversal resource in the message carrying the request for collecting the NAT traversal resource, and sending the message to the destination P2P node; and receiving, by the destination P2P node, the message carrying the request for collecting the NAT traversal resource and the NAT traversal resource, collecting the NAT traversal resource, and sending the NAT traversal resource collected by the destination P2P node and the NAT traversal resource carried in the message to the first P2P node.
