Abstract:
1. A method for implementing traversal of multimedia protocols to enable a terminal in a private network to access a public network with a common address, the method comprising: acquiring, by the terminal in the private network, an address of a terminal in a public network for sending media streams; sending, by the terminal in the private network, a redirect packet to the terminal in the public network, in which a destination address of the redirect packet is the address of the terminal in the public network for sending media streams; wherein a source address in the redirect packet is replaced with the common address and a mapping relationship is established between the source address in the redirect packet before the replacement and the common address in the redirect packet after the replacement; wherein the terminal in the private network is operable for receiving the media streams from the terminal in the public network; wherein a destination address of the media streams is the common address which is replaced with the address of the terminal in the private network in accordance with the mapping relationship; and wherein the terminal in the private network sends redirect packets periodically to refresh timeout time for the mapping relationship.
