Network resource dynamic self-adaption method and system based on network flow priority

Abstract

The invention aims to provide a network resource dynamic self-adaption method and system based on network flow priority, and the method comprises the steps: collecting office network flow data, and predicting the downlink total flow in a period of time in the future through employing a time sequence prediction algorithm; and meanwhile, calculating the priority of the target IP according to the differences of historical uplink flow, downlink flow, data packets and source IP numbers of the target IP in the working time and rest time of the workdays, and establishing a target IP priority library.In combination with the predicted downlink total flow and the destination IP priority, a dynamic bandwidth adjustment strategy is formulated, the bandwidth use of the high-priority destination IP isensured, the office work can be smoothly and efficiently carried out under the condition of limited bandwidth, and meanwhile, the office cost of an enterprise can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of network flow control, in particular to a network resource dynamic self-adaptation method and system based on network flow priority. Background technique [0002] The office network structure of a traditional enterprise unit usually uses a layer 2 switch for access. Each port of the layer 2 switch corresponds to the employee's office station. The traffic flows from the layer 2 switch to the layer 3 switch for aggregation, and then passes through the operator The provided ISP outlet connects to the Internet. Considering the information security of the office network, a firewall is generally added at the network egress. [0003] This networking solution does not control the traffic finely enough. Since the egress bandwidth is fixed, the probability of network congestion will increase as the number of office workers increases. When the bandwidth is fully occupied, the remaining traffic will queue up and wait...

Problems solved by technology

[0005] (1) Restrict access to services that are not related to work by setting an access blacklist. The disadvantage of this solution is that different units need to filter the blacklist according to their own work characteristics. When special circumstances require access to services corresponding to the destination IP in the blacklist , the destination IP needs to be deleted from the blacklist, resulting in reduced work efficiency;

[0006] (2) Limit the upper limit of bandwidth in different office areas. The disadvantage of this method is that when the overall traffic of the office network is low and some departments or workstations have burst access, the bandwidth cannot be effectively utilized.
