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] Preferred embodiments of the present invention will be described in detail below.

[0035] see figure 1 The concurrent data transmission method 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 realized through a new communication protocol. The multiple network interface devices of this embodiment The concurrent data transmission method comprises the following steps:

[0036] 1) The hosts 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 communicate. If the host currently has a network interface that can be used for communication The number of network interfaces is K, and the sequence numbers of marked network interfaces are 0, 1...K-1 (different net...

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 has been proposed. The equipment in the current multi-dimensional network communication technology, such as PC, has multiple network interfaces, but only one network interface can maintain data transmission with other nodes at the same time, does not have the ability to execute multiple data concurrently, and cannot realize cross-network communication . [0003] The existing forms of concurrent data transmission are based on the following two hardware forms: [0004] ●Data parallel transmission of multiple network interfaces [0005] If the two hosts (or one of them) performing the transfer have multiple network interfaces connected to different networks, then there may be different direct IP paths betwee...
