Embodiment Construction

[0044] The present invention will be further described below.

[0045] The control method for alleviating network congestion of the present invention comprises the following steps

[0046] Step 1 establishes the state space model of the network congestion system, the specific method is:

[0047] Firstly, the change data of storage and forwarding nodes is collected, and the state space model of network congestion system network is established by using these data, the form is as follows:

[0048]

[0049] Among them, f(x(t))=(f 1 (x 1 ), f 2 (x 2 ),...,f n (x n )) T Indicates the state of network storage space at time t, n indicates the information type of data flow, u(t)∈R m is the state of the buffer node at time t, m represents the information class of the buffer data flow, R mIt is an m-dimensional real column vector; A and B are weighted matrices composed of node data collected by sensors in real time; considering the positivity of the actual system, that is, x(...

Abstract

The invention discloses a control method for alleviating network congestion. The invention comprises the following steps: step 1, establishing a state space model of network congestion; step 2, proposing a system matrix representation method; step 3, designing angle domain conditions to solve the problem of system state constraints; step 4, designing state feedback of network congestion nodes control law. The present invention realizes effective control of network congestion phenomenon through constraint control, non-linear control design and other technologies, reduces the space occupation of the buffer zone, and reasonably allocates storage space resources of each buffer zone to solve the problem of network congestion.

Description

technical field [0001] The invention belongs to the technical field of automation and proposes a controller design method for alleviating network congestion. Through constraint control, nonlinear control and other technologies, it can effectively control network congestion and reduce the space occupied by the buffer zone. It can be used in the field of network communication. Background technique [0002] Network congestion is a problem often encountered in the process of network communication and has attracted much attention. Many network communications are troubled by this problem to varying degrees. Network congestion can cause delays in information transmission, slow down transmission speeds, and even paralyze network communications. During congestion, there will be data loss, increased delay, decreased throughput, and even lead to "congestion collapse" in severe cases. Generally speaking, there are two types of methods to alleviate network congestion: the first type is...
