Abstract
The utility model relates to a kind of network access devices, including dns server, proxy server, load balancer, Redirect Server and multiple Web servers, the dns server connects user terminal by international gateway, the proxy server and Redirect Server are all connect with dns server, the loaded server is connect with proxy server, the multiple Web server is all connect with load balancer, and the Redirect Server and Web server are also respectively connected with Domestic Carriers and international routing.Compared with prior art, the request of user is balancedly distributed to rear end Web server according to certain load balancing by load balancer by the utility model, the request of proxy server is set uniformly to be transmitted to more Web servers, to achieve the purpose that load balancing, network data processing ability is strengthened, network transfer speeds are improved.
Description
Technical field
The utility model relates to network communication fields, more particularly, to a kind of network access device.
Background technique
Currently, overseas enterprise client mainly accesses website in the country by domestic line, but visited again by domestic line
External general headquarters, mass data need to transmit in a network, will cause the problems such as network transmission is slow, time delay is larger, packet loss is frequent, net
The QoS mass of network is unable to get guarantee, influences the normal use of user.If redeploying an international operator route, need
Redeploy light pricker, have investment increase, open the period it is longer the deficiencies of place.
Utility model content
Biography when the purpose of this utility model is exactly to overcome the above-mentioned prior art to transmit in a network there are mass data
Defeated slow-footed defect and a kind of network access device is provided.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of network access device, including dns server, proxy server, load balancer, Redirect Server and more
A Web server, the dns server connect user terminal, the proxy server and redirection service by international gateway
Device is all connect with dns server, and the load balancer is connect with proxy server, the multiple Web server all with load
Balanced device connection, the Redirect Server and Web server are also respectively connected with Domestic Carriers network and international routing.
Preferably, the proxy server is equipped with 2 or more.
Preferably, the user terminal connects international gateway by couple in router.
Preferably, firewall is equipped between the dns server and international gateway.
Preferably, the load balancer is connect by trunking channel with Web server.
Preferably, the proxy server is Squid proxy server.
Compared with prior art, the utility model passes through load balancer according to certain load balancing for user's
Rear end Web server is balancedly distributed in request, and the request of proxy server is made uniformly to be transmitted to more Web servers, thus
Achieve the purpose that load balancing, strengthen network data processing ability, improve network transfer speeds, has ensured that user accesses state
The speed of outer website.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
It is marked in figure：1, dns server, 2, proxy server, 3, load balancer, 4, Web server, 5, redirection clothes
Business device, 6, user terminal, 7, international gateway, 8, Domestic Carriers network, 9, international routing.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
Embodiment
As shown in Figure 1, a kind of network access device, including dns server 1, proxy server 2, load balancer 3, again
Server 5 and multiple Web servers 4 are oriented, dns server 1 connects user terminal 6, proxy server 2 by international gateway 7
It is all connect with dns server 1 with Redirect Server 5, load balancer 3 is connect with proxy server 2, multiple Web servers 4
It is all connect with load balancer 3, Redirect Server 5 and Web server 4 are also respectively connected with Domestic Carriers network 8 and the world
Routing 9.
Load balancer 3 is connect by trunking channel with Web server 4.
User terminal 6 connects international gateway 7 by couple in router.
Firewall, the safety of Logistics networks communication are equipped between dns server 1 and international gateway 7.
Every Web server 4 is designed with load detecting and connection count functional module.Load detecting functional module is for adopting
Collect the cpu load, memory load and disk behaviour in service information of every Web server 4 and sends it to load balancer
3.It is equal that connection quantity information between connection count functional module acquisition Web server 4 and international routing 9 sends it to load
Weighing apparatus 3.Load balancer 3 obtains above- mentioned information according to the period and is stored in monitoring table, according to the information in monitoring table and sets
Fixed load balancing selects the smallest Web server 4 of load value.
In the present embodiment, proxy server 2 is Squid proxy server 2, is equipped with 2, prevents a proxy server 2
The case where damage causes network communication to be interrupted.
The present apparatus when in use, first has to the network access point for needing to be arranged user terminal 6, passes through strategy in network access point
The IP access at Foreign User end 6 is directed toward international gateway 7 by routing configuration.When accessing domestic network, in international gateway 7
It establishes BGP dynamic routing figure and redirects strategy, matched be routed through of the ASN from Domestic Carriers will be received and redirect clothes
Business device 5 is re-introduced into the incoming node that goes out of Domestic Carriers network 8, realization domestic network access.It is accessed to international network
When, default international routing 9 is matched to international export according to the default route (default-route) of international gateway 7, due to
IP be it is domestic, make the configuration of static ip address one-to-one mapping on port, be world IP, realization by domestic IP static conversion
International network access.
