1. A multi-stream service concurrent transmission method, comprising:
a multi-interface terminal initiating a service transmission request to a network side, wherein the service transmission request carries at least a service ID of requested service and a terminal ID of the multi-interface terminal;
the multi-interface terminal receiving information of database servers capable of providing requested service resources and service information of the requested service from the network side;
the multi-interface terminal establishing a plurality of concurrent links with all or some of database servers corresponding to the information of the database servers capable of providing the requested service resources according to the information of the database servers capable of providing the requested service resources, and dividing service data packets of the requested service according to the service information of the requested service, and notifying the network side of a division result;
the multi-interface terminal receiving the service data packets of the requested service over the plurality of established concurrent links;
the multi-interface terminal evaluating links which transmit the service data packets;
the multi-interface terminal determining a link rate adjustment strategy according to a evaluation result, and notifying the network side of the link transmission rate adjustment strategy for the network side of the adjust transmission rates of various links;
wherein the step of the multi-interface terminal evaluating the links transmitting the service data packets comprises:
when the multi-interface terminal evaluating a link transmitting the service data packets at time t, calculating path weight of the link according to criteria comprising a bandwidth estimation value of the link at the time t, an average round-trip time delay of the link at the time t, and a retransmission statistical value of the link at the time t, wherein each of these criteria are further weighted by factors representing service grade information and the preference of transmitted service to various performance parameters of the link.
