TWI273793B - Method for retrieving real-time network configuration parameters and lease time definition - Google Patents

Abstract

The present invention provides a method for retrieving real-time network configuration parameters and lease time definition. The network configuration protocol used in the conventional TCP/IP (transmission control protocol/Internet protocol) is a DHCP (dynamic host configuration protocol), and a lease time scheme is also employed to retrieve the allocated network configuration parameter. The lease time is a period of specific time. However, the conventional DHCP is unable to retrieve the network configuration parameters of the subscriber immediately when the user is off line. Therefore, the present invention discloses a method for retrieving network configuration parameters and lease time definition in real time, which can retrieve the network configuration parameters allocated to the subscriber when the user is off line. When the user is connected to the network next time, the user will be notified to enable the DHCP again so that the efficiency of using network configuration parameter resources can be effectively enhanced.

Description

1273793 IX. Description of the invention: Xian, Cai: Tr.·

[Technical Field] The present invention is a method for real-time network configuration parameter time definition, which is used to improve the TCP/IP fresh-receiving and renting ΓΠΗΓΡΛ^ Method. Lease Time as a recovery network configuration parameter [prior art]

网路Network configuration parameter configuration commonly used on TCP/IP networks, ^ is the dynamic host configuration protocol (DHCP: Dynamic Host mgum 1 Qn Pr.t(10)1), for the configured network configuration parameters. The Host Configuration Protocol (hereafter referred to as DHCP) informs the client of the validity period of this network configuration parameter by defining the a/month % parameter (Lease Time).

When the client requests the configuration of the network configuration parameters from the DHCP server, the server, in addition to configuring the network configuration parameters to the user terminal, also informs the user of the validity period of the network configuration parameters. This validity period = the definition of the parameter of the lease time, the length of the lease period has no standard... It is the network administrator who defines the flood time. ~△ The reason why the DHCP protocol uses the lease time to perform the recovery mechanism of the configured network group T is because the MCP agreement cannot grasp the status of the client device and the f, that is, the client does not specify the client=line. The DHcp server must be notified of the offline message first, so the server cannot actively detect whether the DHCp client is still online (on line), so the Dj|Cp server cannot grasp and know the user's 1273793 offline. The situation, therefore, can not do the network configuration parameters of L·"...;;;:::::, so only the raw recycling configuration can be given to the validity period of the user route configuration parameters. The lease time is used to limit the user network's use of the flood protocol and configuration parameters due to the DHCP protocol, so it is bound to be: as a recovery of the configured network - configuration configured for the user several problems: will make the configuration The efficiency of the use of parameter resources is recovered when the user is offline. Second, the user system cannot be completely recorded. During the validity period, the user can have any status, and the status of the road, because the network configuration does not need to be reconfigured during the lease period. The login and offline network, third, the lease period can not be used within the time limit 'does not mean that the user is using the test' because because of the lease term, the lease time is not standard, the network configuration parameters are There is no long lease time on the configuration resource, which will cause the user to continuously issue an extended period. Secondly, the short period of time to be t will be the first to use the first picture, and the intention is to use the second picture to illustrate. 2: The flow of the process is constructed, and the third diagram illustrates the time of the MCP period (Lease Time) to recover the allocated white 0. How to use the lease-step to explain the custom connection authentication mechanism do J of control after the UE (Access Control) method. Sub-taken, first, please refer to the figure - diagram, which is a schematic diagram of the conventional regional network architecture. First, a plurality of client-side communication devices 10 are connected to the network switch 16 by means of a wired (Wired) connection. , or wirelessly connected to the wireless base station (Wireless Access P〇int) i8 12737793 4 * J 0 ¥月曰修(more) is replacing the page connection' whether it is the above network switch or wireless base station, Basically, the physical connection between the client device and the local area network is provided. Therefore, the following are generally referred to as Network Access Device; the route is (Router) 12 is used to provide cross-network segments. Routing function; Since the topology of the local area network (Network Topology) can be large or small, the Internet (2) is used to indicate the path (PATH) that passes between the router 12 and the server. The DHCP server 14 is mainly Provides the functionality of a DHCP service. Please refer to the second figure as a flow chart of the method for obtaining the network configuration parameters and the lease time by the custom client via the DHCP server. First, the client communication device 10 starts the DHCP configuration configuration request (si〇〇), and Send a _

The DHCP Discover (DHCPDISCOVER) packet is sent to the DHCP server 14, which is used to find available DHCP servers. In the Hierarchical Network Architecture, the DHCP server is usually not in the same network segment as the client device (SUBNET). In this case, it must be through the router (R〇uter)12.

Perform DHCP Discover Packet forwarding (DHCP RELAY). The dhcp discovery packet sent by the client device is received by the router and added to the router address and other information (RELAY).

The setting content of the router itself directly transmits the DHCP discovery packet to the DHCP server. After the DHCP server 14 receives the DHCP discovery packet sent by the router 12, the DHCP server performs a configuration decision mechanism (81〇2), and then roots.

According to the information of the content of the package, it is decided to configure (Αιι.ru) to the user to configure the network configuration parameters and the lease time, and the basis for determining the network configuration parameters may be the user equipment. Media Access Control Address (MAC 7 1273793

When the configuration mechanism of the DHCP server determines the network to be configured for the client device, it is sent out _ 赃 简 简 ) 封 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四After the client device 1G receives and provides the packet, it checks the content of the configuration parameter contained in the packet (phantom 4), and the client device determines the number of network packets and requests the DHCP server. 14 When the network group sorrow parameter is actually configured (S1 〇 6), a DHCP request (DHCP REQUEST) packet is sent, and the packet is received by the router 12 and forwarded to the DHCP server 14. After the DHCP server 14 receives the DHCP request packet, the configuration decision mechanism determines whether the client device accepts the network configuration parameter (sl〇8). When the determination is yes, the configuration decision mechanism will actually configure this. The configuration parameters are sent to the client device (S110), and a DHCP acknowledgement (DHCPACK) packet is sent to the router, and the router forwards the packet to the client device. Here, the main function of the DHCP acknowledgement packet is to determine that the DHCP server is configured. This network parameter is given to the client device. The client device 10 receives the DHCP acknowledged packet, and can determine that the DHCP server 14 has configured the network configuration parameter. At this time, the user equipment finally obtains the network configuration parameter and the lease time, and can start the start. Initialization work (S112). The initialization work mainly obtains the user's network configuration parameters and lease time and sets up the Internet transport protocol stack (TCP/IP STACK). The network configuration parameters include the network address of the user's 1273793 ( IP), network mask (3 Xianli 7 job), router address (ROUTER IP), domain name service host address (10) s Ip), Microsoft name resolution host address (WINS IP) and other related networks The road configuration parameters, when the client device completes the initialization work, can communicate with other devices on the network using the overnight protocol of the Internet Protocol. The second picture of the Ming tea test is the traditional DHCp agreement to use the lease time method Γπ回: the flow chart of the method of configuring the network configuration parameters, first the user (9) two DHCP protocol to obtain its network configuration parameters and rent The time of the new Nisko η / (four) households use this network configuration parameters equal to the time of the second update == to the request - the new lease time '-like the package client will wait for the DHCM server 14 The reply of the group period door (S2 = to = when the package is wrapped, the user can get - new ^ i i'J fa1 'bmw' # T2), :; re, time, (Rebinding Time; The broadcast time is 7/8 lease time. At this time, the client 1 cycle = (10) 8 heavy) The new binding packet is used for the fixed seal: the terminal will wait for the DHCP server to reply and re-bundle the package. The client has not received the reply from the client. The network configuration parameters are up to the time of use. When the lease time is reached, the client 10 must have the original network configuration parameters and restart the DHCP start. Protocol 1273793, 屯二. (S214), please refer to the standard network agreement document rfc 213 卜 RFC. At present, due to the need of network security, some network switches 16 and hotline base stations 18' themselves have connection authentication functions (Port-based Ac: e, s Control;), that is, they will be directed to the connected client. After the process of verifying the identity, the connection with the client 9 is opened to the client device, which enhances the security of the client and the local area network connection. The standard connection authentication protocol is 802. lx age. For related network files, please refer to the standard network protocol (RFC 2865, RFC 3579, RFC 3580). The schematic diagram of the regional network architecture of the first picture of the same test is taken. When the access switch 16 or the wireless base station 18 has the connection authentication function, the temple will be authenticated for the user 1G. In addition, the certified feeding service is 22 to centrally verify the user identity. The authentication feeding device α is responsible for storing the user account database and verifying the identity of the user, for example, performing remote operation.

Remote Authentication Dial-In User Service) The authentication server (Authenticati〇nServer), the authentication server 22 finally notifies the network switch 16 of the result of the verification to the wireless base station 18 to determine whether to open the connection. . The network access device, such as the network parent switch to 16 or the wireless base station 18, in addition to using the authentication server 22 to help verify the identity of the client, also transmits the message records such as the user login and offline to the accounting server ( Accounting Server) 24, for example, the accounting access server (RADIUS: Remote Access Dial-ln User Service) agreement accounting server (Accounting Server) is used to record the connection and offline situation of the client, and Can be used as a test for future billing; please moxibustion 1273793

The connection authentication mechanism is the 802·lx protocol. The standard protocol masters the access control method of the network access device for its connection port and the method of the second-end identity authentication. When the connected user successfully passes the identity After the 13th sequence, the network access device will open the connection to the client at this time. The standard 802 1x protocol reference files are WU579, RFC3580 and RFC3748. In addition, the network access device can also use the webpage. Login confirmation The way to provide connection authentication mechanism, because the 802. 1 connection authentication protocol is only required, the client and the network access device must simultaneously execute the 802·lx protocol software, in order to avoid If the client device implements the 8〇21χ protocol software, the user identity authentication cannot be performed. In this case, the network access device supports the webpage login authentication=eb-l0gin) to achieve the same user identity authentication. The purpose of this #日守客户端 is to perform identity authentication through the webpage. — The above connection authentication mechanism uses the 802·lx Extensible Authentication Protocol (EAP) to send identity authentication data to the network. Receiving the device, the network access device forwards the received extensible authentication protocol (ΕΑΡ) data to the authentication server for the user identity verification work, and executes the network access device and the authentication server. Network protocol between the two, can be accessed using standardized remote access dial-in user service (RADIUS), terminal access controller Systematic System (TACAS) 10 or Lightweight Directory Access Protocol (LDAP), etc. Standardized Remote Access Dial-In User Service (RADIUS), Terminal Access Controller Access Control System (TACAS) or lightweight Directory Access Protocol (LDAP) and the like mainly provide unified user identity authentication work, and notify the network access device of the result after verification, so the remote access dial-in user service (RADIUS) and the terminal access controller are executed. The server that takes control system (TACAS) or Lightweight Directory Access Protocol (LDAP) program is generally called authentication server 1273793. I» Ά, Ll month; Japanese repair (more) is replacing: The main work of the 伺服 伺服 servo state is responsible for the identity verification work of the client, and informs the network to accept the switch after the verification, when the user succeeds Through the identity verification, the authentication server notifies the user of the successful message through the network communication protocol with the network access device, and then the network access switch will connect the connection with the client.埠Open to allow the client to use the port. After the user successfully passes the identity verification, the authentication server also records the user information included in the network connection authentication protocol packet, including the user's media access control address (MAC address), and the network to which the user is logged in. · The device picks up the IP address and the port number on the network access device. When the user terminals successfully pass the connection authentication mechanism of the network access device, the connection port on the network access device has also been turned on, and the client device uses the dynamic host configuration protocol (DHCP) to obtain the device. The required network configuration parameters. The client must configure the configuration parameters of the network configuration parameters (S304) for the network configuration parameters. Please refer to the second figure for the procedure for the client to obtain its network configuration parameters. Once the client device has obtained the network configuration parameters and completed the initialization of the TCP/1P stack (TCP/1P STACK), it can communicate with other network devices using the TCP/IP Internet Protocol until the The client is offline. There are many reasons why the client can be offline. For example, the client actively logs out (Logout), the client reboots (Reboot), the network fails (port failure), the network reopens (Port Reinitial), and re-authenticates. 1273 7Q2 ί—4; 19 I year month d (more) positive replacement: .................. ~ ~W.~w~y*. .m.. . Re-authentication Failure and so on. Therefore, when the user terminal is offline, the network access device must be able to detect (Monitor) and determine the offline reason of the client (S306) 'because the client and the network access device are executed at the beginning The connection authentication mechanism, such as 802.1 χ, Web-Login, so the connection authentication mechanism can now play its role of mastering the connection and offline status of the account, while the offline status of the user occurs. 'You can immediately determine the cause and status message of the user offline. Please refer to the Termination Code for offline users in the standard network agreement file RFC 3580. After the connection authentication mechanism performed on the network access device detects and determines that the user has an offline situation and generates an offline reason code (Termination Code), the network access device must send the user offline message to the network. The road configuration parameter configuration server (S308), the standardized user per-line §fl notice mode can be dialed into the user service RADIUS Accounting Protocol or the terminal access control 10 device access control through remote access The system's TACAS Accounting Protocol is completed. Please refer to the standard network agreement document (RFC 3579) for the definition and description of the RADIUS accounting protocol for 802·lx and remote access dial-in user services. After the offline phenomenon occurs on the user side, the remote access dialing user service billing agreement uses the accounting-request packet to send the user offline ACL (Acct-Terminate-Cause Attributes). Using the remote access dial-in user service RADIUS Accounting Protocol or the terminal access controller access control system 16 1273793 r ^ t, · A TACAS Accounting Protocol can be more complete Users offline messages, but can also use the more common Simple Network Management Protocol (SNMP: Simple Network Management Protocol) or syslog protocol (SYSLOG Protocol) to send users offline message records; please refer to the network standard agreement file (RFC) 3164, RFC 3411, RFC 3413) The embodiment adopted by the present invention is described by remote access to a RADIUS Accounting Protocol. When the 802·lx protocol is used to detect and judge the offline status of the client (S306), and then the remote access is used to dial the user service accounting protocol to transmit the user offline message to the network configuration parameter configuration server. (S308), at this time, the network configuration configuration server must cooperate with the RADIUS Accounting Server program for remotely accessing the accounting agreement of the dial-in user service, and the main purpose is to receive the sfL information packet of the offline user ( Accounting-request packet). Please refer to the fifth figure. When the network configuration parameter configuration server receives the offline message packet (S31〇A) through the implementation of the accounting protocol (Account i ng Pro toco 1), Next, remove the network configuration parameters configured by Seto & from the network configuration parameter configuration database or let the network configuration parameters be released. Since the network configuration parameter server uses Dynamic Host Configuration Protocol (DHCP) to configure the network configuration parameters of the client, when the network configuration parameter is configured, the server receives the accounting message packet and the user is offline. If you are obedient, you must define a user feature value from the user's offline message (S310B) 'This user feature value must exist in the user's offline message / η

The ID 17 1 coffee 3 packet must also exist in the network configuration parameter configuration database of the network configuration parameter configuration server. In the present invention, the media access control address of the user terminal is mainly used (Media Access Control Address). : MAC) to define this user feature value. The user feature value definition can also be a composite combination, using a computer name or a user name plus a media access control address, etc., but the most important thing is that the user feature value must be present in the user's offline message content at the same time. And found in the network configuration parameter configuration database. • The network configuration parameter configuration server takes the user characteristic value of the offline user from the offline packet of the user, and then uses the user feature value as an index key to search the comparison network. The path configuration parameter configures the record on the network configuration parameter database of the server (S310C). Since the configuration information on the network configuration parameter database must also have this user feature value, this method can be used to find The network configuration parameters configured by this offline user. However, if you use Simple Network Management Protocol (SNMP) or System Log Counseling (SYSL0G) to transmit the user's offline message packet, the user's feature value will not be found on the packet, but on the packet. Recording the Internet access device address (IP address) and port number of the offline spring user, you can use the initial network connection authentication protocol user record poor information, connect the network The device address and the nickname are taken to obtain the feature value of the user, such as the media access control address (MAC address) of the user. After the comparison finds the offline user network group sorrow configuration record on the network configuration parameter configuration table, the network configuration parameter configuration server removes the record from the user configuration table or The release action 18 Μ 1273793, Lu: (^ 1 Π Λ · ~ - , , thus completed the purpose of the user network configuration moxibustion parameter recovery (S312).
