Description
Technical field
The present invention relates to a kind of network management, relate in particular to a kind of dynamic IP network VPN management and the method for monitoring (Management System of Dynamic IP Virtual Private Network).
Background technology
As the strange land networking technology of a maturation, set up VPN with broadband line and approved by more and more business and government institutional settings and use that VPN is simple and convenient owing to the broadband line establishment, with low cost, safe, with respect to other private network building technologies, very big advantage is arranged.But existing broadband line substantially all uses dynamic IP, so for the user who does not have condition application special line and static ip address in a large number, and the how immediate addressing and managing of the VPN equipment of various places?
At present, the dynamic IP administrative skill in the vpn solution mostly is based on dynamic territory analyzing system (DDNS) in the industry.
What is called dynamic territory analyzing system mainly is in order to solve the binding issue between domain name and the dynamic IP addressing.When the user uses different IP login, the dynamic territory analyzing system with the change dynamics of IP address be mapped in the corresponding D dns server, upgrade automatically timely.The dynamic territory analyzing system generally is made of two parts: first is a server, is positioned on the main frame of service provider; Another part is a client-side program, just operates on users' the main frame.In each connection network, client-side program is by the information transmission, the dynamic IP addressing of this main frame is sent to the server program that is positioned on service provider's main frame, server program is responsible for providing the DNS service and is realized the dynamic territory analyzing service, receiving client notice back server new data more immediately, with new IP address and the binding of original fixedly domain name, so just finished the service of dynamic territory analyzing.Server end only is responsible for receiving and upgrading, and whether not responsible feedback is received and commands client is retransmitted, and is the system of a pure one-way transmission.
Dynamic territory analyzing is based on such operation principle:
The function of DDNS service is exactly to realize that fixedly domain name is to the parsing between the dynamic IP addressing.The each online of user obtains after the new IP address, all will upgrade this domain name mapping database to the DNS application; When on the Internet other people will visit this domain name, the dynamic territory analyzing server will return correct IP address.
But also there is following defective in such method:
The first, poor reliability:
In the DDNS mode, the new IP address of user can not replenish submission automatically after submitting failure to automatically, necessary manual intervention.
This be because, dynamic-dns is that the dynamic IP of unidirectional transmission is submitted mechanism to, lacks affirmation mechanism, just server side only is responsible for receiving the information that the user reaches the standard grade or rolls off the production line, and does not carry out both sides' feedback information.Like this, submission side can not get following inspection and confirms after new IP is sent.When situations such as network congestion or circuit are interfered occurring, dynamic IP is submitted failure to, because submission side lacks affirmation mechanism, so can't replenish submission, causes submitting to failure, message delay.When network delay is big, can also can't obtain confirming according to timeout treatment.In case network breaks down, the VPN broken string is then wanted manual intervention, less stable.Recovery time is longer, and especially when operator-less personnel or duty personnel are not on duty, this is quite disadvantageous concerning the higher enterprise of stability and reliability requirement.
The second, the IP renewal speed is slow:
The detection of dynamic-dns and submission cycle generally are that real-time was poor at 5 ~ 30 minutes.Because the main body agreement of DNS originally is for static IP designs, the modification of the corresponding IP of domain name is manual amendment's configuration file.Dynamic-dns is the technology of switching to a job one was not trained for, and expands on original DNS Protocol, has kept the favorable compatibility with traditional DNS system, but the excessive problem of load when also having caused dynamic IP to upgrade simultaneously.Owing to need take a large amount of system resource of dns server when upgrading IP, also very poor to the resistivity of malicious attack simultaneously so that common dynamic-dns server all is provided with renewal frequency is very low to avoid the server overload, a little less than system is highly brittle.
Though the DDNS mode can solve the problem of dynamic IP addressing,, then cause many interior machines of whole local area network at a VPN equipment place to sink into for a long time to interrupt if network breaks down.Even the public network circuit recovered in several seconds again, DDNS picks up new IP dozens of minutes after, and VPN could heal again at this moment.Automatically upgrade failure in system, under the situation that administrative staff can't put in place, even can interrupt several days.This is beyond affordability for the client that those real-times are had relatively high expectations.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of dynamic IP network VPN management and the method for monitoring, and are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the present invention realizes by following steps:
VPN client and LIST SERVER are set up the data double-way transmission;
LIST SERVER is in charge of and is monitored by administrative staff, and by data-base recording and data query;
Wherein: whether client comprises by local state detection module, be responsible for detecting local IP and change;
If local IP changes, increase the formation task of uploading, the record transformation period;
By with the server communication on transmission module, be responsible for the IP transformation period comparison of will write down on the IP transformation period of this locality and the server, if inconsistent, then upload local IP, if consistent, then show and upload success, delete this locality and upload task;
By with server communication download module, whether have downloading task, downloading task generation time and the local last generation time of downloading successful task on the contrast server if detecting server end, if it is inconsistent, then need download message,, then show the last downloaded success if consistent;
By the VPN control module, according to the up-to-date VPN network information of downloading on the server, adjust local VPN configuration, the tunnel that changes for those opposite ends IP rebuilds and repairs;
LIST SERVER comprises by the communication part of router node uploads the state recording module with each node, is used for being responsible for the last change time of each node IP of record, and is as the criterion with the time of router node;
By downloading task state recording module, be responsible for producing the task that each node needs download message, and generation time stabs;
By authentication module, whether the responsible identity that detects each node meets the data in the database communication module, is responsible for and the data-base recording system communication, and recording operation history obtains authentication information;
By the practical work administration module, be responsible for accepting the order of management and maintenance system, produce corresponding task and submit to the downloading task module;
