Method for transmitting multipath data packets and system thereof

Abstract

The invention discloses a method for transmitting multipath data packets and a system thereof. By the method and the system, the multipath data packets can be transmitted by a same network socket, thus improving the working efficiency of transmitting the multipath data packets. The method for transmitting the multipath data packets comprises the following steps: the network socket which includes a route cache array for caching the routing information of the multipath data packets is established; the routing information of the multipath data packets is obtained and added to the route cache array; when transmission of the multipath data packets is needed, the routing information of the multipath data packets is obtained from the route cache array, and the multipath data packets are transmitted according to the routing information.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for sending multi-channel data packets. Background technique [0002] In the application of the CRBT server based on the Linux operating system, a large number of audio files need to be transmitted to the IP network. However, if you want to transmit audio data through the IP network, you need to convert the audio file into an IP datagram, and send the data packet through a network socket (UDP). [0003] UDP is used to send data packets, and the prior art generally includes: [0004] Step 1. Call the creation (socket) system to realize the creation of a network socket. [0005] Step 2, calling the binding (bind) system to realize the binding of the network socket with the local IP address and UDP port. [0006] Step 3, call the sending (sendto / sendmsg) system to realize sending UDP data packets to the remote host. [0007] Wherein, when sendin...

AI Technical Summary

Problems solved by technology

However, when the destination IP addresses of multiple data packets are different, only the method of creating separate network sockets for each channel of audio can be used to send, but the cost of system calls, routing query overhead and process / thread switching in this way will be larger

In the prior art, each time a network socket is used to send a data packet, only the destination IP address of one data packet can be cached, so it is impossible to use the same network socket to send multiple data packets with different destination IP addresses

[0016] In summary, the existing technology cannot use the same network socket to send multiple data packets
