A network protocol flow control system

Abstract

The invention belongs to the technical field of flow control, and discloses a network protocol flow control system, which comprises a data packet detection module, a virus detection module, a flow monitoring module, a main control module, an address identification module, a transmission control module, a flow filtering module, a flow classification module, a caching module and a display module. According to the invention, the network address to be filtered can be matched with the node in the binary tree filtering model for less times through the flow filtering module to determine whether the network address to be filtered is a known network address or not, and then the network address to be filtered is filtered. The storage analysis data volume of the network traffic is greatly reduced, sothat rapid filtering of the network traffic is realized; classifying by combining an unsupervised algorithm and a supervised algorithm in a machine learning method through a flow classification module; the combination of the two can reduce the system time and memory overhead on the premise of ensuring higher classification accuracy, and improve the classification efficiency.

Description

Technical field [0001] The invention belongs to the technical field of flow control, and particularly relates to a network protocol flow control system. Background technique [0002] A network protocol is a collection of communication rules between all devices on the network (network servers, computers and switches, routers, firewalls, etc.). It specifies the format and meaning of these formats when communicating. Most networks adopt a layered architecture, each layer is built on top of its lower layer, to provide certain services to its upper layer, and the details of how to implement this service are shielded from the upper layer. The rule for communicating between the nth layer on one device and the nth layer on another device is the nth layer protocol. There are many protocols in each layer of the network. The receiver and sender must have the same protocol at the same layer, otherwise one party will not be able to identify the information sent by the other party. The netwo...

Problems solved by technology

[0004] When the existing network protocol flow control system performs network flow filtering, it results in a large amount of network flow storage and analysis data, which occupies more system resources; at the same time, the accuracy of the network flow classification algorithm is low, and the system time and memory consumption are high.
