Dominant factor method based network sharing bandwidth dynamic allocation method

Abstract

The invention relates to a network sharing bandwidth dynamic distributing method based on the dominant gene method, using the method in the invention, in the every circuit that the network nodes distributes the network sharing bandwidth dynamically, the system can make decision according to the user's requirement, the PRI of data flow and the flux and distribute the sharing bandwidth, and uses the network source rationally, that includes following processing: step 1, according to the user's requirement, the PRI of data flow and the flux, it produces a decision-making value which can effect the distribution for the bandwidth of data for the data flow with highest PRI before the distributing the bandwidth; step 2, according to the decision-making value, the system will decide the distributing strategy, and distributes the bandwidth for the data flow; step 3, using the sparing bandwidth in the system, it distributes the sharing bandwidth for the data flow with lower PRI based on the dominant gene method.

Description

technical field [0001] The invention relates to a processing method for implementing dynamic allocation of shared bandwidth in a network with shared links, and has strong practical value in the field of network communication. Background technique [0002] As shown in Figure 1, in an actual network, there are not always enough resources for different data streams to have completely independent traffic paths, so it is inevitable that there will be multiple data streams passing through the same path and sharing a link with limited bandwidth. road. When configuring shared link bandwidth, you usually encounter the following problems. [0003] Operability issues: The configuration method is complex and highly professional, requiring guidance from the technical support personnel of the network equipment manufacturer, and users are prone to errors in self-configuration. [0004] Rationality problem: Users usually know the importance of each connection data flow, but they can o...

Problems solved by technology

[0003] Operability issues: The configuration method is complicated and highly professional, requiring guidance from the technical support personnel of the network equipment manufacturer, and the user's self-configuration is error-prone

[0004] Rationality problem: users usually know the importance of each connection data flow, but they can only simply use the fixed bandwidth allocation method to allocate the corresponding bandwidth for each connection. This allocation method is relatively random and has unreasonable factors

[0006] Timeliness problem: After the user completes the bandwidth allocation, it usually remains unchanged for a long time, and the update rate is low

However, the control of network bandwidth allocation has its particularity, which is manifested in the fact that the control method of bandwidth limitation has an uncertain impact on the source traffic using different protocols, and its effect makes the source traffic of different protocols increase, decrease or remain unchanged. possible

Therefore, the real-time bandwidth allocation control scheme of traffic feedback is not an ideal research direction in the research of dynamic bandwidth allocation algorithms.
