Method for realizing data message transmission based on RTP

Abstract

The invention provides a realization method for data message transmission based on RTP, which comprises: the communication device determines random value according to received data message to determine transmission port for message; then, it sends the data message. This invention uses every port evenly, special makes good use of broadband resource of the logic ports, ensures the order transmission for RTP data message, and cuts network resource.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an implementation method of RTP-based data message transmission. Background technique [0002] In the network communication system, data communication can be carried out between two data communication devices through the FE port of 10 / 100M and the Ethernet port of GE port of 1000M. [0003] When multiple FE / GE ports are used for communication between two data communication devices at the same time, multiple FE / GE ports can be bundled into a logical port with larger bandwidth. figure 1 As shown, multiple FE / GE ports between the data communication device 1 and the data communication device 2 are bundled into one logical port, and the data communication device 1 and the data communication device 2 communicate through the logical port. [0004] When using a logical port for communication, you can configure only one IP address and MAC address for the logical port, which...

Problems solved by technology

[0006] When two large-capacity network devices such as two media gateways of NGN (Next Generation Network) communicate, the initiation point and termination point of the session are the two gateways, because there are only a small number of IP packets between the two gateways MAC address, IP address, and the number of port numbers of IP packets is limited, and the allocation rules are fixed. Therefore, using MAC addresses, IP addresses, or port numbers to identify sessions will make a large number of IP packets In this way, the physical ports in the logical ports are used unevenly, so that the bandwidth resources cannot be fully utilized, the bandwidth utilization rate is reduced, and the bandwidth resources are wasted, and the purpose of saving bandwidth by bundling Ethernet interfaces is not achieved.
