Abstract: A data interaction method is provided, which includes: sending simultaneously an address detection request for a UDP channel and an address detection request for a TCP channel; and when both address detection for the UDP channel and address detection for the TCP channel fail, sending an address detection request for an HTTP channel; when detection of at least one channel succeeds, collecting two types of addresses corresponding to each channel in the at least one channel; performing address exchange and address matching with a peer client host; and performing channel connectivity detection based on matched addresses, and selecting a channel with a highest priority from channels on which connectivity detection is successful for data interaction with the peer client host. Therefore, efficiency of traversing a NAT host during address detection is improved.

Abstract: A method and an apparatus for sending an Ethernet physical-layer OAM overhead, and a method and an apparatus for receiving an Ethernet physical-layer OAM overhead are disclosed herein. A method for sending an Ethernet physical-layer OAM overhead includes: adjusting the order of sending a payload block and part of Inter-Packet Gaps (IPGs) in a data stream to be transmitted; and when receiving a request for sending an OAM overhead, substituting the OAM overhead for the part of IPGs, and sending the OAM overhead before sending the payload block. Through the present invention, the order of sending IPGs and payload blocks in an MAC data stream can be adjusted, and the OAM overhead can be sent in time.
