Description
Technical field
The present invention relates to the implementation method of a kind of user login name and IP address binding.
Background technology
Nowadays broadband access online is very general.In the sub-district, school, enterprise even operator's broadband access all replaced narrow band access fully.Along with popularizing of broadband, bandwidth operator and broadband user also have higher requirement to broadband user's management.
The management overwhelming majority of the present network equipment is based on that IP carries out.Based on IP, the equipment of different levels has been made a lot of characteristic functions, such as: dynamically ACL, IP-based charging, rights management, QOS management, safety management etc.And in the broadband application of reality, what really need is management at the people, rather than IP-based management.That is to say,, comprise said all the IP-based application in front, all will lose its meaning if the user that the people is just surfed the Net and IP do not connect.
So just there is a problem, how the people and the IP address of surfing the Net connected? existing method is:
1, fixedly IP or IP and fixed port binding of configuration.
2, the MAC Address of IP address and computer binding.
3, in the authentification of user online, user's IP address is limited.
Be not difficult to find out that from above implementation method these methods are based on following hypothesis:
1, the position at people place is static relatively;
2, a people only may be in same local online;
3, a machine only can use for a people (number of the account) online;
4, machine can not move;
5, people and machine are one to one.
Above implementation method can solve IP and people are linked together under the situation that above hypothesis satisfies, but also just because of will rely on above hypothesis, makes above-mentioned said method be restricted and can not satisfy the demands fully.
Generally speaking, the realization mechanism of said method is to be limited to the people rather than to serve the people.Design and method provided by the invention is based on the thought of serving the people, do not rely on above-mentioned hypothesis.The network user uses the number of the account of oneself to land as long as in certain area coverage, will obtain identical IP address, that is to say it is to be bundled on people's (perhaps number of the account) with IP, rather than people or number of the account are tied up on IP.
The product of realizing at present the IP address binding generally all is the static binding that realizes the IP address, just based on the hypothesis described in the background technology, has limited user's the method that moves, and below the said method in front is described in more details:
1, fixedly IP or IP and fixed port binding of configuration.
This method is to dispose fixed IP addresses on machine, and perhaps in switch or other access devices, corresponding different ports disposes different IP addresses.This (a bit) machine has just been monopolized corresponding IP address like this, and the business of corresponding IP just is directly connected to the user of these machines.This mode relatively is fit to server or work station, is not suitable for the personal user.
2, the MAC Address of IP address and computer binding.
This mode is to dispose the one-to-one relationship of machine (network interface card) MAC Address and IP on Dynamic Host Configuration Protocol server.When the user surfed the Net back initiation DHCP request, DHCP for the user distributes the IP of appointment, thereby realized the said demand in front according to the MAC Address of subscriber set.This mode is suitable for, and user and machine be situation one to one.
3, in the authentification of user online, user's IP address is limited.
This mode realizes by AAA the user checks by aaa server whether user's IP address conforms to configuration in network access authentication, do not allow the user surf the Net if just meet.This function can be used other IP online by limited subscriber, and the method one common and front is used jointly.
4, utilize radius protocol to realize.Performing step is as follows:
1, configure user binding IP on radius server;
2, when the user authenticates, in responding Access-Accept message to equipment, RADIUS carries the Framed-IP-Address attribute, and property content is the IP address of user binding;
3, the packet parsing that returns according to radius server of equipment goes out the IP of user binding, and distributes to the user.
Three kinds of methods of the relative front of this method are flexible many, and the user can move within the specific limits, to machine also without limits.
Said method 1 is relatively wasted IP, and is very dumb, is not suitable for the personal user;
Said method 2 is not suitable for the shared machine of many people; Be not suitable for mobile subscribers such as notebook; Configuration is inconvenient, is difficult to safeguard; Mechanical disorder or replacing network interface card have just more bothered;
Said method 3 is dumb, reality user's the use that only has been passive restriction, rather than initiatively provide service, constraint user freedom;
The advantage that said method 4 has simply, easily realizes; But this method than higher, has limited the selection of unit of operation and the network service unit of providing to the requirement of equipment and dependence.Equipment will be discerned RADIUS and respond the Framed-IP-Address attribute that carries in the Access-Accept message to equipment, and it is distributed to the user.Have only the processing of a few devices support at present, and implementation can not unify, a lot of troubles may occur in the butt joint the Framed-IP-Address attribute.In addition in actual networking, may have various equipment, may not be same company, and the realization of agreement is also had nothing in common with each other, in this case, problems such as problem of coordinating with regard to the matching problem that has RADIUS and distinct device, with other manufacturers and operation equipment online upgrading.So though this mode is available in theory, actual poor operability.
