Data transmission using connection-less and connection-oriented transmission layer protocols

A data transmission apparatus for real-time communications over a computer network, the data transmission apparatus comprising:

• a processor;
• and
• memory storing computer-readable instructions that, when executed, cause the data transmission apparatus to:
• generate session offers of a communication session;
• transmit the session offers to a destination end based on a connectionless-oriented transmission layer protocol and a connection-oriented transmission layer protocol respectively, the transmitting including:
• encapsulating the session offer into first interaction signaling based on the connectionless-oriented transmission layer protocol;
• encapsulating the session offer into second interaction signaling based on the connection-oriented transmission layer protocol;
• and
• transmitting the first interaction signaling to the destination end by using the connectionless-oriented transmission layer protocol, and transmitting the second interaction signaling to the destination end by using the connection-oriented transmission layer protocol;
• determine, based on transmission statuses of session answers fed back by the destination end responsive to the session offers, respective connectivity detection results of a connectionless transmission channel and a connection transmission channel of the communication session, wherein the determining includes:
• determining that a session answer fed back by the destination end for the first interaction signaling is only received through the connectionless-oriented transmission layer protocol, and responsive to the determining that a session answer fed back by the destination end for the first interaction signaling is only received through the connectionless-oriented transmission layer protocol, storing a destination end candidate address that is used to transmit session data and that is in the session answer, and determining that the connectionless transmission channel of the communication session is in a connected state;
• or
• determining that a session answer fed back by the destination end for the second interaction signaling is only received through the connection-oriented transmission layer protocol, and responsive to the determining that a session answer fed back by the destination end for the second interaction signaling is only received through the connection-oriented transmission layer protocol, storing a destination end candidate address that is used to transmit the session data and that is in the session answer, and determining that the connection transmission channel of the communication session is in a connected state;
• establish a data transmission channel to the destination end based on the connectivity detection results;
• and
• transmit the session data of the communication session with the destination end through the data transmission channel.
