Problems solved by technology

[0012] 1. Excessive dependence on the server: When the virus center server is paralyzed, the virus prevention nodes in the entire LAN cannot complete the virus database upgrade; when the virus sub-center server is paralyzed, all virus prevention nodes connected to it cannot be upgraded ; The above two situations will cause serious security risks to the system;
[0013] 2. The system sets several virus sub-center servers on the lower layer of the virus center server, although the load on the center server is reduced, but the deployment cost is increased

Embodiment Construction

[0033] The technical solutions and technical effects of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The structure of the local area network terminal virus database upgrading system described in the present invention is as follows: figure 1 Shown:

[0035] According to the figure, it can be seen that the system is composed of four parts: a file upgrade management module 101, a network module 102, a file upgrade module 103, and a downloader 104. The main functions of each part are as follows:

[0036] 101 File upgrade management module: communicate with the server to obtain the latest virus database version number; responsible for finding the parent node that can provide services, sending download commands to the download module and maintaining a service queue to provide services for requesting service nodes;

[0037] 102 network module: process the underlying network communication messages; ...

Abstract

The invention discloses a local area network virus library upgrading system and method based on peer-to-peer technology (P2P), relating to the computer network technical field and aiming at improving upgrading speed of host virus library in local area network and reducing server load. The system includes a file upgrading management module, a network module, a file upgrading module and a downloader. The method includes that: all the terminals in local area network are allocated with the virus library upgrading system, thus all the terminals in local area network can be used as a service requesting node or a service providing node; when the local area network is not existed with a service providing node with virus library in latest version, the service requesting node downloads the virus library in latest version from the server; and when the local area network is existed with the service providing node with virus library in latest version, the service requesting node downloads the virus library in latest version from the service providing node. The implementation of the invention is mainly used for upgrading host virus library in the local area network.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a local area network virus upgrading system and method based on peer-to-peer (p2p for short). Background technique [0002] With the development of the Internet, more and more computer viruses have sprung up, and the variants of the existing computer viruses are of a great variety, and there is a growing trend. Therefore, regularly updating the virus database is one of the necessary ways to ensure network security. The existing virus database upgrading methods are all based on the traditional client / server model. When the local upgrade program starts the upgrade, it first requests the remote server to download the latest virus database signature, and compares it with the local signature. When it is found that the local virus database is outdated, it requests the server to download the latest virus database for upgrade. Contains the following steps: [0003] 1. The se...
