Abstract
The invention relates to an IP adaptation-based load balancing method and a system thereof. The method comprises the following steps that: 1) a mobile terminal roams in a foreign network and initiates a connecting request message to an IP adaptive front-end service unit; 2) after receiving the connecting request message, the IP adaptive front-end service unit transmits a request message to a real server unit; 3) after receiving the request message, the real server unit directly returns a connecting response message carrying an address of the real server unit to the mobile terminal and creates a tunnel from the real server unit to the mobile terminal; and 4) after receiving the connecting response message, the mobile terminal acquires the address of the real server unit and creates the tunnel from the mobile terminal to the real server unit. The method and the system can overcome the service bottleneck of a single-server network, ensure the high quality, high throughput rate and high performance of network services, lighten the burden of the IP adaptive front-end service unit and be applied to various application network services of an IP layer and above.
Description
Invention field
The invention belongs to the network security technology field, relate to a kind of based on adaptive load-balancing method of IP and system thereof.
Background technology
The computer nowadays network, because simplicity, ease of manageability and the ease for maintenance of client or server model are adopted in a large number, the IP adaptive network is continued to use this kind model too.Along with the develop rapidly of Internet, bring great challenge for the network bandwidth and server.From development of internet technology, the growth of the network bandwidth is far above the growth of processor speed and internal storage access speed.The reason that 10Gigabit Ethernet, 100Gigabit Ethernet are difficult to make its throughput reach 1Gb/s on server is the poor efficiency of protocol stack (TCP/IP) and operating system, and the poor efficiency of processor.This needs a kind of technology can make the service of IP adaptive network can comply with the growth requirement of Internet, break the application of client/server naive model, make full use of resources such as operating system and processor, the network service of high-throughput is provided, realizes the load balancing of IP adaptive network service.
Summary of the invention
There is following defective in the scheme of existing load balancing:

In order to solve existing above-mentioned technical problem in the background technology, the invention provides a kind of based on adaptive load-balancing method of IP and system thereof.
Technical solution of the present invention is: the invention provides a kind ofly based on the adaptive load-balancing method of IP, its special character is: this method may further comprise the steps:
1) mobile terminal roaming is initiated connection request message to field network to IP adaptive front-end service unit;
2) after IP adaptive front-end service unit is received connection request message from portable terminal, the message that sends a request message is given the real server unit;
3) after the request message message was received in the real server unit, the connection response message that the real server unit will have the real server element address directly returned to portable terminal, and created the tunnel from the real server unit to portable terminal;
4) after portable terminal is received the connection response message of sending from the real server unit, obtain the address of real server unit, and create tunnel from portable terminal to the real server unit.
Above-mentioned steps 2) concrete steps are as follows:
2.1) after IP adaptive front-end service unit is received connection request message from portable terminal, select a real server according to the destination address hash;
2.2) after true server unit is selected, carry out the reorganization of IP bag, the request message message is encapsulated in another IP bag;
2.3) IP adaptive front-end service unit is transmitted to selected real server unit to packaged IP bag.
Above-mentioned steps 3) concrete steps are as follows:
3.1) the real server unit carries out deblocking after receiving the IP bag that transmits from IP adaptive front-end service unit, obtains the message before the IP adaptive front-end service unit package;
3.2) the real server unit finds that the destination address of former message is the external address of IP adaptive front-end service unit, begins to handle connection request;
3.3) the real server unit directly returns to portable terminal according to the connection response message that routing table will have the real server element address; Simultaneously, the tunnel of establishment from the real server unit to portable terminal.
Above-mentioned steps 4) comprises also that afterwards the step 5) portable terminal communicates by tunnel and real server unit.
Above-mentioned steps 5) also comprises the ruuning situation of step 6) IP adaptive front-end service unit real time monitoring real server unit afterwards, change the destination address hash table, adjust scheduling strategy.
A kind of based on the adaptive SiteServer LBS of IP, its special character is: comprise the portable terminal that sends connection request and set up the tunnel and communicate with the real server unit to IP adaptive front-end service unit based on the adaptive SiteServer LBS of IP, the connection request that mobile terminal receive sends and this connection request is transmitted to selection the real server unit IP adaptive front-end service unit and receive connection request that IP adaptive front-end service unit transmits and with this connection request corresponding issue portable terminal and and portable terminal set up the real server unit in tunnel.
The invention provides a kind of IP tunnel that utilizes and between real server and portable terminal, set up a tunnel, reach the purpose of multi-mobile-terminal to the IP adaptive load balancing of server, can solve Single-Server network service bottleneck, the high-quality that can guarantee the network service, high throughput rate and high performance, can alleviate IP adaptive front-end service unit burden, applicable to IP layer and above types of applications network service based on adaptive load-balancing method of IP and system thereof.Concrete advantage is as follows:
1) can solve the bottleneck that Single-Server becomes the network service.The present invention makes the IP adaptive network balanced to the load realization of Single-Server, and having solved Single-Server becomes the bottleneck that network is served.
Description of drawings
2) high-quality, high-throughput and the high-performance of network service.The present invention can make many webservers form a group, has guaranteed high-quality, high-throughput and the high-performance of network service.
3) can avoid the single-point performance of network service to become bottle-neck of network communication.Data communication of the present invention is to finish in the tunnel, without IP adaptive front-end service unit, compares like product, has alleviated the burden of IP adaptive front-end service unit, avoids the single-point performance of network service to become bottle-neck of network communication.
4) scope of application is wide.The present invention is suitable for IP layer and above types of applications network service, and simultaneously, the present invention can on-the-fly modify the IP strategy, in time avoids the influence of non-movable real server unit to portable terminal, and the scope of application is quite wide.
