Description

How to Provide Self-Service

technical field

The invention relates to the field of data communication, in particular to a method for providing self-service in an Internet network system.

Background technique

With the gradual increase of users' demand for self-service, many Internet Service Providers (ISP, Internet Service Provider) and Internet Content Providers (ICP, Internet Content Provider) have provided self-service services to users. Currently, self-service mainly provides users with the following services:

The user sets the user name and password for accessing the self-service website in his own way, and can modify the set user name and password at any time as needed, so it is convenient for the user to remember his user name and password information;

Users can check their own network traffic and network time at any time;

Users set the bandwidth of the network they use, and choose access control capabilities for accessing network resources, and customize some services such as virtual private network (VPN, Virtual Private Network) services, storage services, multicast services, security services or tariff services according to their own conditions and other aspects of application business.

At present, the main way for each ISP or ICP to provide users with self-service is to set up a dedicated autonomous server in the center of its own network system, which is mainly used to store various information of users registered on this autonomous server, such as the user's username information, user password information, information on network traffic used by users, and information on network time used by users, etc. The autonomous server can search for the database corresponding to the user according to various query information requests sent by the user, and feed back the corresponding information found to the user; User password, etc.) and customized services (such as VPN service, storage service or multicast service, etc.), and store the corresponding setting information and customized services in the database corresponding to the user.

However, each ISP or ICP adopts the above-mentioned self-service provision method. When a user accesses the autonomous server, he needs to use IE (Internet Explorer) on his own client to key in the IP address or Universal Resource Locator (URL, Uniform Resource) of the autonomous server. Locator), and then log in to the autonomous server through the IP address or URL information of the autonomous server to access various self-service resources provided by the autonomous server; the user can further access and query the corresponding resources by entering their own user name and password on the autonomous server. Your own self-service resources. Therefore, this self-service provision method also requires users to remember the IP address or URL information of the autonomous server in order to log in to the autonomous server to access various self-service resources provided by the autonomous server; For IP address or URL information, you need to further remember your user name and password for accessing self-service resources, so as to access the corresponding self-service resources.

To sum up, the existing self-service provision methods mainly have the following deficiencies:

Users are required to remember the IP address or URL information of the autonomous server in order to access various self-service resources provided by the autonomous server, which is very inconvenient for users to use;

Similarly, users are required to remember their username and password information in order to access their own self-service resources on the autonomous server, which is also very inconvenient for users to use;

If the autonomous server changes due to network upgrades or changes in the self-service provider, the self-service provider needs to notify all users of the IP address or URL information after the change in the autonomous server in order to make the network system autonomous The server is accessed normally, so it is less maintainable.

Contents of the invention

The technical problem to be solved by the present invention is to propose a method for providing self-service, so that users can access various self-service resources provided by the self-service server at any time without memorizing the IP address or URL information of the self-service server. It is convenient for users and beneficial for self-service providers to maintain their own servers.

In order to solve the above problems, the present invention proposes a method for providing self-service, which is used to provide self-service for a network system. The network system includes a client, an authentication device, an authentication server, an autonomous server, and a storage unit. The client Identify yourself by identifying yourself, including:

(1) storing the address information of the autonomous server in the storage unit;

(2) After the authentication server authenticates the identity of the client, and the authentication device allows the client to access network resources, the address information of the autonomous server stored in the storage unit is sent to the client;

(3) The client uses the received address information of the autonomous server to access the public self-service resources provided by the autonomous server.

The step (1) further includes: when the address information of the autonomous server changes, updating the address information of the autonomous server stored in the storage unit in time; and sending the changed address information of the autonomous server to the client.

The address information is the IP address of the autonomous server or the universal resource locator of the autonomous server.

The user uses the corresponding user self-service request identity as the legal key to access the corresponding self-service resource.

Step (1) also includes: establishing a mapping relationship between the identity of the client and the identity of the user's self-service request, and storing the mapping in a storage unit;

In the step (2), after the identity of the client is authenticated, it also includes: the storage unit searches for the corresponding user self-service request identity in the mapping relationship according to the identity of the client, and sends the found user self-service request The identity is sent to the client;

After step (3), it also includes: the client combines the received universal resource locator of the autonomous server and the identity of the user self-service request into a new universal resource locator, and uses the new universal resource locator to send the URL to the autonomous server. Access the self-service resources corresponding to the user on the provided public self-service resources.

The beneficial effect that the present invention can reach is as follows:

The self-service providing method of the present invention stores the address information of the autonomous server in advance, and after the identity of the client is authenticated, sends the stored address information of the autonomous server to the client, and the client receives the address of the autonomous server Information accesses the self-service resources provided by the autonomous server, so users are not required to memorize the address information of the autonomous server; at the same time, when the address information of the autonomous server changes, the self-service provider does not need to notify each user of the changed address information of the autonomous server. Therefore, the user can use the self-service more conveniently, and it is convenient for the maintenance of the self-service provider.

The self-service providing method of the present invention also stores the mapping relationship between the identity of the client and the identity of the user's self-service request, so that the client can combine it into a new The universal resource locator to access the self-service resources corresponding to the user in the autonomous server, so the user is not required to remember his own user self-service request identity, which also provides convenience for users to use self-service.

Detailed ways

The design purpose of the self-service providing method of the present invention is: in the network system providing self-service, the address information of the autonomous server (which can be the IP address of the autonomous server, or the universal resource locator URL of the autonomous server) is stored in advance , when the subsequent client has a need to access the Internet, after the identity of the client (that is, the ID information of the client required to access the Internet, generally including the user's username and password information, etc.) Client, the client accesses the public self-service resources provided by the self-service server according to the received address information of the self-service server.

Furthermore, when the stored address information of the autonomous server is a URL, the ID of the client and the identity of the user self-service request (that is, the ID of the user self-service request) can also be established as a mapping relationship. When the network resources can be accessed through authentication, the ID of the corresponding user self-service request is searched in the mapping relationship formed according to the client ID; Send them to the client respectively, and the client will combine the URL of the autonomous server and the ID information of the user's self-service request into a new URL as the access parameters for accessing the self-service resources corresponding to the user on the public self-service resources provided by the autonomous server. To achieve the purpose of accessing the self-service resources of the corresponding user.

To sum up, the user can directly access the self-service resource without memorizing the address information of the autonomous server and the ID information of the user self-service request, which provides great convenience for the user. The specific implementation of the self-service providing method of the present invention will be described in detail below in conjunction with the embodiments:

Among them, in the network system that provides self-service functions, it generally includes an autonomous server, which is used to provide users with various self-service resources; it also includes a client, that is, a terminal computer device that browses web pages for users and accesses the autonomous server; it also includes The storage unit is used to store the address information of the autonomous server and other relevant information, etc. With reference to Fig. 1, this figure is the flow chart of utilizing the self-service providing method of the present invention to access public self-service resources, and its specific implementation process is as follows:

Step 10, first store the address information of the autonomous server (that is, the URL information of the autonomous server or the IP address information of the autonomous server) in the storage unit by the network administrator through the man-machine interface, such as in a network system that provides self-service functions, the autonomous server When the address information of the server is 192.168.0.1 or www.Selfservice.com, the IP address 192.168.0.1 is stored in the storage unit or the URL information www.Selfservice.com is stored in the storage unit; and subsequent network upgrades and other reasons When the address information of the autonomous server changes, the network management personnel should update the stored address information of the autonomous server to the new address information of the autonomous server through the man-machine interface in time.

Step 20, when the user is going to browse Internet resources through the client, at first the identity ID (comprising user name and password) of the client is authenticated, and judges whether authentication can pass, if yes, then go to step 30; If not , go to step 50.

Step 30, if the authentication is passed, that is, the ID of the client is legal, the client is allowed to access the Internet system and browse Internet resources, and then the storage unit sends the pre-stored address information of the autonomous server to the client.

Step 40, after the client receives the address information of the autonomous server, if it judges that the address information is valid, it will use the address information of the autonomous server as a parameter for accessing the autonomous server, and input the address information to the client In the browser IE owned by the terminal itself, an HTTP connection request is initiated to the autonomous server as a Web access parameter. In this way, the user can log in to the autonomous server through the client, access the public self-service resources of the autonomous server, and access the public self-service resources on the public self-service resource webpage. It's done.

Step 50, the authentication fails, that is, the ID of the client is illegal, and the network system will not allow the client to access the Internet system, so the process ends.

However, after processing through the above process, the user can only access the public self-service resources provided by the autonomous server through the client, but cannot enter the corresponding self-service resource webpage. Establish a mapping relationship between the service request identity and the client ID and store the mapping relationship, so that after the client ID is authenticated, the URL of the main server and the corresponding user self-service request identity are sent to the client at the same time, The client uses these two pieces of information as parameters for accessing the self-service server, and then can enter the self-service resource webpage corresponding to the user on the public self-service resources provided by the self-service server. Referring to Fig. 2, this figure is a flow chart of using the self-service providing method of the present invention to access the self-service resources of corresponding users, and its specific implementation is as follows:

Step 100, first establish a mapping between the ID of the client and the identity of the user's self-service request corresponding to the client (mainly including the user name and password for the user to access the corresponding self-service resource, hereinafter referred to as the ID of the user's self-service request) Relationship, refer to Figure 3, which is a schematic diagram of the mapping relationship between the ID of the client and the ID of the user's self-service request; The ID of the user self-service request for B is b, where A and B mainly include the user name User and password information Key that the client needs to input when requesting to surf the Internet; a and b mainly include the user’s request to access the corresponding self-service resources The user name User and password information Key that need to be entered.

In step 200, respectively store the URL of the master server and each mapping relationship formed in step 100 into a storage unit.

Step 300, when the user intends to browse Internet resources through the client, firstly the ID of the client is authenticated, and it is judged whether the authentication can pass, if yes, then go to steps 400 and 500 respectively; if not, then go to step 900.

In step 400, the storage unit sends the URL of the pre-stored autonomous server to the client; at the same time, in step 500, the storage unit finds the ID of the corresponding user self-service request in the stored mapping relationship according to the ID of the client, and then in step In 600, the storage unit also sends the found ID of the user self-service request to the client;

In step 700, the client first uses the received URL information of the autonomous server to access the public self-service resources of the autonomous server, and then combines the received URL of the autonomous server and the ID of the user's self-service request to form new URL information. The combination is illustrated with an example: for example, when the URL of the self-server is http://www.selfserver.com/service/self.htm, the client and the self-server agree on the user name "UserName" (here the user name UserName and its The corresponding password information is the ID of the user self-service request). Now there is a user named "zhangsan" who needs to use self-service; then the client will send the URL of the self-service server:

http://www.selfserver.com/service/self.htm

Combine with the user's username zhangsan to form a new URL:

http://www.selfserver.com/service/self.htm? UserName=zhangsan.

In step 800, the client uses the combined new URL as a Web parameter to access the self-service resource corresponding to the user on the public self-service resource provided by the autonomous server, and initiates an HTTP connection request to the autonomous server, so that the user can pass The client goes to the autonomous server and then accesses the corresponding self-service resource webpage, and performs corresponding query operations and setting operations on the corresponding self-service resource webpage.

In step 900, the authentication fails, that is, the ID of the client is illegal, and the network system will not allow the client to access the Internet system, so the process ends.

In order to ensure that the user can access the self-service resources at any time after the ID of the client used by the user passes the authentication, and at the same time, in order to reduce the number of transmissions of the device with the storage unit, the self-service provision method of the present invention adopts the following triggers Sending conditions and sending interval mode:

Trigger send condition:

(1) After the ID of the client is authenticated, the storage unit sends the address information of the stored autonomous server or the ID information of the user's self-service request to the client in time;

(2) After the stored address information of the autonomous server changes, the storage unit sends the changed stored address information of the autonomous server to the client in time;

(3) After the ID of the client is authenticated, the storage unit also sends the stored address information of the autonomous server or the ID information of the user's self-service request to the client at a dynamic time interval in the subsequent time.

The dynamic time interval is set as follows:

Set the initial period value t, the maximum period value T and the period step value Δt respectively;

The storage unit assumes that the sending cycle value=t+(n-1)Δt between the nth time and the n+1th time;

Determine whether the sending period value=t+(n-1)Δt is greater than or equal to the maximum period value T, if yes, the maximum period value T is used as the sending period value between every two subsequent transmissions; if not, use t+(n -1) Δt is used as the sending cycle value between the nth and n+1th times;

where n is a natural number.

Referring to Fig. 4 for the sending rule of the above-mentioned dynamic time interval, this figure is a schematic diagram of the sending rule using the dynamic time interval in the self-service providing method of the present invention. After the ID information is sent to the client, after time t, send it for the second time; after time t+Δt, send it for the third time; after time t+2Δt, send it for the fourth time;..... ..After the time t+(n-2)Δt, send the nth time; until the time interval between two transmissions is t+XΔt≥T, then the time interval between each subsequent two transmissions will take this The maximum period value T is used as the sending period value. From this, it can be seen that the transmission period of this dynamic time interval transmission method is gradually increased according to the set step value until it increases to a certain extent, and a maximum fixed transmission period is used for transmission, so it can reduce the number of storage units provided. The number of transmissions of the device, correspondingly reduces its workload.

At the same time, in the network system that provides self-service functions, it further includes an authentication server, which is mainly used to authenticate the ID of the client to determine whether it is a legal user client; it also includes an authentication device, which is mainly used to The server authenticates the client's ID to determine whether the client is allowed to access network resources. If the authentication is passed, the client is allowed to access the network resource; if the authentication fails, the client is denied access to the network resource. The equipment is mainly switches, routers, access points and other equipment in the communication network system. In the self-service providing method of the present invention, the storage unit may be set in the authentication device, or in the authentication server.

Taking the 802.1X authentication network system in the local area network as an example below, the method for providing self-service of the present invention is described in detail. Of course, the method for providing self-service of the present invention is not only limited to being used in the local area network system of 802.1X authentication mode, but also can be used For other network systems using other authentication methods, this is just an example for illustration.

With reference to Fig. 5, this figure is the structural principle diagram of 802.1X authentication network system in the prior art local area network system; The operating principle of each entity in the figure is as follows:

When the client 1 has a need to access the Internet, it first transmits its own ID information to the authentication server 6 through the network system 3 via the authentication port 5 in the authentication device 2, and the authentication server 6 performs an authentication operation on the ID information of the client. If the authentication passes , then the authentication server 6 sends an authentication success message to the authentication device 2, and after receiving the authentication success message from the authentication server 6, the authentication device 2 makes the port providing service port 4 in itself open, so that the client 1 can pass through The opened port accesses network resources; if the authentication fails, the authentication server 6 sends an authentication failure message to the authentication device 2, and after the authentication device 2 receives the authentication failure message from the authentication server 6, it makes the service port 4 in itself The port of is closed to deny Client 1 from accessing network resources through this port.

In the above-mentioned 802.1X authentication process, the message transmitted between each entity is an Extensible Authentication Protocol (EAP) message. Referring to Figure 6, this figure is the standard format of the existing EAP message, and the fields are from left to right during transmission. Transmitted sequentially, wherein the Code field occupies one byte and is used to identify the type of the EAP message, as shown in FIG. 7 , which shows the main four types of EAP messages in the prior art. The figure shows that when the message type code in the Code field is 1, it means that the transmitted EAP message is an authentication request message (Request); when the message type code in the Code field is 2, it means that the transmitted EAP message is The message is an authentication response message (Response); when the message type code in the Code field is 3, it means that the transmitted EAP message is an authentication success message (Success); when the message type code in the Code field is 4 , indicating that the transmitted EAP packet is an authentication failure packet (Failure).

However, the above four types of messages have been used in the prior art 802.1X authentication process, so it is necessary to expand another message on this basis to carry the address information of the master server or the ID information of the user's self-service request; Referring to FIG. 8 , this figure shows a message type extended in the self-service providing method of the present invention. A code representing the self-service message (Service) is encapsulated in the Code field of the standard EAP message format, and the code can be any code except 1-4, for example, 10. Then, in the Type field of the standard EAP message format, the address information (Self-Service-Addressinfo) of the autonomous server is encapsulated, and of course the ID of the user's self-service request can also be encapsulated. In this way, it can ensure that the extended self-service message still conforms to the EAP message format, and can also carry the address information of the autonomous server or the ID information of the user's self-service request, and transmit it according to the standard transmission protocol in the 802.1X authentication network system. The specific application of the self-service providing method of the present invention in the 802.1X authentication network system will be described below by setting the storage unit in the authentication device.

With reference to Fig. 9, this figure is the self-service providing method of the present invention in the 802.1X authentication network system, the process diagram of transmitting the address information of the autonomous server; its specific implementation process is as follows:

Step S1, the client sends its own ID information to the authentication device to request to browse Internet resources.

In step S2, the authentication device sends the ID of the client to the authentication server through its own authentication port, and the authentication server authenticates the ID of the client.

Step S3, the authentication server authenticates the ID information of the client. If the authentication is passed, it sends an authentication success message to the authentication device; if the authentication fails, it sends an authentication failure message to the authentication device. In the present invention, only the authentication server Step S4 is executed only after the authentication success message is fed back.

In step S4, the authentication device sets its own service-providing port to an open state according to the received authentication success message, allowing the client to access network resources, and correspondingly provides a basis for users to access self-service resources.

The authentication process of the authentication server to the client in the existing 802.1X authentication network system is roughly as follows:

When the client needs to access the Internet, it enters the user name and password in the ID information respectively; at the same time, it sends an authentication request message to the authentication device;

After receiving the authentication request message, the authentication device instructs the client to send the user name;

The client sends the username to the authentication device, and the authentication device forwards the received username to the authentication server;

The authentication server compares the received user name with the user name stored in its own database, finds the password information corresponding to the user name, and encrypts the password information with a randomly generated encrypted word, and at the same time passes the encrypted word through the authentication device. to the client;

After receiving the encrypted word, the client encrypts the password with the encrypted word and sends it to the authentication server through the authentication device;

The authentication server compares the received encrypted password information with its own encrypted password information. If they are the same, the client is considered legitimate and sends an authentication success message to the authentication device; The client is illegal and sends an authentication failure message to the authentication device;

After receiving the successful authentication message from the authentication server, the authentication device sets the service port to open to allow the client to access network resources; otherwise, sets the service port to close to deny the client access to network resources.

Step S5: After receiving the authentication success message sent by the authentication server, the authentication device encapsulates the address information of the autonomous server stored in the storage unit into an extended self-service message, and then sends the self-service message to the client .

Step S6: After receiving the self-service message sent by the authentication device, the client first performs an unpacking operation to parse out the address information of the autonomous server encapsulated in it. If the resolved address information of the autonomous server is valid, then The client will activate the self-service function;

The above activation can be understood as activating (Activate) a process, or activating a function option of the currently active process. For example, the menu is in an unavailable "grey" state before receiving a self-service message, and after parsing the self-service message and extracting the address information of the autonomous server, if it is valid, the menu will be in an available state;

The client inputs the resolved address information of the autonomous server into its own IE, and establishes an HTTP connection request with the autonomous server by using the address information of the autonomous server as the web access parameter for accessing the autonomous server;

After logging in to the self-service server, the user can access public self-service resources.

Referring to Fig. 10, this figure is a process diagram of transmitting the address information of the autonomous server and the ID information requested by the user for self-service in the 802.1X authentication network system of the self-service providing method of the present invention; its main implementation process is the same as that in Fig. 9 , where step S50 is different from step S5. In step S50, after receiving the authentication success message sent by the authentication server, the authentication device encapsulates the URL of the autonomous server stored in the storage unit and the ID information of the user self-service request into the Extended self-service message, and then send the self-service message to the client; step S60 is also different from step S6, in step S60, after the client receives the self-service message sent by the authentication device, it first resolves Package operation, which parses the URL of the self-service server encapsulated in it and the ID information of the user's self-service request. If the parsed URL of the self-service server is valid, the client will activate the self-service function; the client first passes the parsed out The URL accesses the public self-service resources of the self-service server. After logging in to the self-service server, the client then combines the parsed URL of the self-service server and the ID of the user self-service request to form a new URL, and then enters the combined new URL In its own IE, by using the combined URL as the Web access parameter for accessing the corresponding self-service resources, an HTTP connection request is established between the autonomous server; the user can then access the corresponding self-service resources. The implementation of other steps is the same as that of the corresponding steps in Fig. 9 , and will not be repeated here.

Similarly, the self-service providing method of the present invention may also place the storage unit in the authentication server. After the authentication server authenticates the ID information of the client, the authentication server sends an authentication success message to the authentication device, so that After the authentication device allows the client to access network resources, it then sends the self-service message stored in the storage unit to the client through the authentication device. More details.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
