Problems solved by technology

If the transmission is performed concurrently on the main path and the backup path directly, due to the different transmission delays of different paths, the data packets will arrive at the receiving end out of sequence. When the delay difference is large, the receiving end may send three intervals to the sending end Report, so that the sender thinks that packet loss occurs and retransmits unnecessary

Embodiment Construction

[0034] The preferred embodiment of the present invention will be described in detail below.

[0035] See figure 1 The method for concurrent data transmission of multiple network interface devices in this embodiment is implemented by improving the SCTP protocol. It is not difficult for those skilled in the art to understand that this method can also be implemented through a brand-new communication protocol. The multiple network interface devices in this embodiment The method of concurrent data transmission includes the following steps:

[0036] 1) The host at the sending end and the receiving end can automatically detect the number of network interfaces that the host has that can be used for communication through the improved SCTP protocol, and mark the network interfaces that can be communicated. If the host currently has the available for communication The number of network interfaces is K, and the serial numbers of the marked network interfaces are 0, 1...K-1 (different network i...

Abstract

The invention belongs to the technical field of network, in particular relates to a data concurrency transmission method of a multi-network interface device. The method comprises the following steps: (1) a transmission end and a reception end detect the amount of network interfaces for communication and label the network interfaces so that each network interface for communication has a serial number; (2) the transmission end divides the data to be transmitted into a plurality of message segments and adds transmission serial number for each message segment; (3) the transmission end remainders the transmission serial number of the message segment to the amount of the network interfaces and transmits the message segment according to the obtained remainder by selecting the corresponding network interface; and (4) the reception end orders the received message segments. The invention can fully utilize the traditional network to solve the problems of unreasonable data distributing and dispatching, disordered reception, low retransmission efficiency, and the like by an improved grouping dispatching algorithm.

Description

Technical field [0001] The invention relates to the field of network technology, in particular to a data concurrent transmission method of multiple network interface devices. Background technique [0002] At present, the concept of multi-dimensional network communication is proposed. Devices in the current multi-dimensional network communication technology, such as PCs, have multiple network interfaces, but only one network interface can maintain data transmission with other nodes at the same time. They do not have the ability to execute multiple data concurrently, and cannot achieve cross-network communication. . [0003] The existing forms of implementing concurrent data transmission are based on the following two hardware forms: [0004] ● Parallel data transmission with multiple network interfaces [0005] The two hosts (or one of them) that are transmitting have multiple network interfaces, and these interfaces are connected to different networks, then there may be different di...
