Server data forwarding method and device

Abstract

The present application discloses a server data forwarding method and device, wherein the method includes: when the server receives a data packet from a firewall, obtains the IP address and sending port of the firewall carried in the data packet, and determines the corresponding data packet Packet type, the data packet type includes a real-time transport protocol RTP packet and an RTP control protocol RTCP packet; the server determines the data corresponding to the data packet according to the IP address, the sending port number and the data packet type Index value Key; according to a preset index relationship, determine the internal port corresponding to the Key, and send the data packet to the determined internal port; the index relationship is used to indicate the server internal port corresponding to each data index value . By adopting the invention, the reliability of data forwarding by the server can be improved.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a server data forwarding method and device in the scenario of network equipment accessing the server. Background technique [0002] When the network device communicates with the server through the public network (hereinafter referred to as the public network), the frequently used network scenarios are as follows: figure 1 As shown: network device A transmits data to firewall C added by server D through the public network, firewall C sends data to server D, and server D sends data to network device E. [0003] suppose figure 1 Network device A and network device B make a voice call. The real address of terminal A is 192.168.1.3, the port for sending audio RTP packets is 2000, and the port for sending audio RTCP packets is 2001. After the data passes through the public network, it reaches firewall C. Firewall C will use ports 19800 and 19801 to send the data to server ...

AI Technical Summary

Problems solved by technology

[0016] It can be known from the above calculation that Key1=Key2, so in the Relation table, a Key value corresponds to two internal ports (4900, 4901), so that server D may send all RTP packets and RTCP packets received from port 21000 of the firewall Sent to an internal port, resulting in an error in the server's internal transmission, which in turn affects the normal operation of user services

[0017] Aiming at the above problems, there is no corresponding solution
