Data transmission method, apparatus, and terminal

A data transmission apparatus, comprising:

• a first establishment module for establishing a plurality of physical connections between a first network element and a second network element;
• a second establishment module for establishing a plurality of virtual connections on each of the physical connections,
• wherein network status information of the plurality of virtual connections is detected and
• recorded in a routing table;
• a selection module for selecting a first virtual connection from the plurality of virtual connections based on a pre-determined rule and the routing table;
• and
• an execution module for executing a data transmission process on the selected first virtual connection;
• wherein detecting network status information of the plurality of virtual connections and
• recording network status information of the plurality of virtual connections in a routing table further include:
• detecting network status information of the physical connection between the proxy server and the first network element;
• detecting network status information of the physical connection between the proxy server and the second network element;
• and
• when the plurality of physical connections between the plurality of proxy servers are established,
• detecting network status information of the plurality of physical connections between the plurality of proxy servers.

A terminal, configured to establish a plurality of physical connections between a first network element and a second network element;

• establish a plurality of virtual connections on each of the physical connections;
• detect network status information of the plurality of virtual connections and record network status information of the plurality of virtual connections in a routing table;
• select a first virtual connection from the plurality of virtual connections based on a pre-determined rule and the routing table;
• and
• executing a program code of steps of a data transmission process on the selected first virtual connection;
• wherein detecting network status information of the plurality of virtual connections and
• recording network status information of the plurality of virtual connections in a routing table further include:
• detecting network status information of the physical connection between the proxy server and the first network element;
• detecting network status information of the physical connection between the proxy server and the second network element;
• and
• when the plurality of physical connections between the plurality of proxy servers are established,
• detecting network status information of the plurality of physical connections between the plurality of proxy servers.
