Problems solved by technology

[0010] Third, the allocation of IP network bandwidth is not fixed
If C2 transmits data to C1 and C3 through the server, if it sends data to the server according to its own bandwidth capability, the server will also have to transmit data to C1 and C3 at the same rate, and the bandwidth between C3 and the server is 3M, so there is no problem , but the bandwidth between C1 and the server is only 1M, so a large number of data packets will be late or even lost on the C1 client, seriously affecting the quality of data communication

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] With reference to accompanying drawing, a kind of method for network load balancing in multipoint communication comprises the steps:

[0032] Step 1. Before sending data to the server, each client uses the accumulated unsigned integer type variable to mark the source sequence number of the data packet.

[0033] Step 2. While receiving the data packets sent by the client, the server counts the serial number of the source, and regularly counts the out-of-sequence rate TC and loss rate LC of the data packets sent by the client, and sends the obtained results to the client.

[0034] Step 3: After receiving the out-of-sequence rate TC and loss rate LC of its own data packets, the client adjusts its own data packet transmission density according to these two parameters, so as to ensure the smooth transmission of data packets.

Abstract

This invention discloses a network load balance method in multi-point communication, which comprises the following steps: before the user sends data to server, he uses sum unsigned integral variable as data pack to mark the source sequence code; the server receives the user data pack and makes statistic of the source sequence code to get the user error sequence ratio and loss ratio and sends the result to the user for adjusting his data pack sending intensity; the server repack the data and marks the transfer sequence code and send to the other users and the users in the same way gets the data pack error sequence ratio and loss ratio to adjust their data pack sending intensity.

Description

technical field [0001] The invention relates to a network load balancing technology used in IP network multipoint communication, and is a network bandwidth load balancing method for IP network data transmission. technical background [0002] With the popularization of the Internet, multi-point communication technology under the IP network environment is being used more and more widely, from wide-area data sharing to audio and video communication conferences, from VOIP on-demand to the popular P2P data transmission. The impact of multipoint communication technology on people's work efficiency and quality of life has become more and more important, and the factor that has the greatest impact on performance in IP network multipoint communication technology is the asymmetry and inhomogeneity of network bandwidth, because data transmission The problem of network bandwidth load generated during this time has increasingly become a bottleneck problem restricting the development of m...
