Multi-service multi-network converged communication scheduling method and system, medium, terminal and application

Abstract

The invention belongs to the technical field of communication networks, and discloses a multi-service multi-network converged communication scheduling method and system, a medium, a terminal and an application. Aiming at the problems that the emergency network bandwidth is limited, the total bandwidth is unstable and key flow transmission cannot be guaranteed, the invention provides an algorithm for dynamically adjusting the bandwidth based on data queue detection, and a multi-service multi-network converged communication scheduling method based on HETB is constructed according to the algorithm. Optimizing the traffic structure according to the network scene; a token bucket algorithm HETB with an elastic priority is obtained, so that key traffic borrows enough bandwidth in an emergency, and communication is completed. The bandwidth preemption strategy based on data queue detection is designed, the real-time communication requirement of high-priority service network resources is met, and meanwhile low-priority service data can also be transmitted. The method greatly improves the availability degree of the network, and is high in speed and good in effect.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a HETB algorithm-based multi-service multi-network fusion communication scheduling method and system, a storage medium, an information data processing terminal, and an application. Background technique [0002] After earthquakes, floods, forest fires and other emergencies, the communication in the disaster area will often be interrupted regionally due to power and facility damage, resulting in "communication holes". Establishing emergency communication in time is necessary to help decision-making departments understand the disaster situation in a timely manner and arrange rescue forces. However, emergency communication in disaster areas often faces the problem that the actual bandwidth of the network is relatively small compared with the required bandwidth, and the frequency of burst traffic is high, which leads to link congestion.

AI Technical Summary

Problems solved by technology

[0010] (1) When a disaster occurs, power and communication are often interrupted at the disaster site. The temporary network built to solve emergency communication often has network congestion problems caused by small bandwidth and large burst traffic, which affects communication efficiency.

[0011] (2) The existing technology cannot meet the real-time communication requirements of low-priority and high-priority business network resources under the impact of sudden large traffic at the same time, and the practicability is limited

[0012] The difficulty in solving the above problems and defects is as follows: ensuring the reliable transmission of critical traffic is a difficult problem. The difficulty lies in how to balance the bandwidth competition between critical traffic and ordinary traffic. It is easy to be interrupted. On the contrary, the transmission of critical traffic cannot be guaranteed. This patent proposes a dynamic bandwidth occupation mechanism. While ensuring the transmission of critical traffic, it also takes into account the transmission of ordinary traffic, so that it will not be in the transmission of critical traffic. terminated immediately

[0013] The significance of solving the above problems and defects is: when an emergency occurs, there will often be large-scale power outages, infrastructure damage, public network congestion to varying degrees, weakened or even no signal, and it is difficult to establish a strong Guarantee of Communication Guarantee
