Description
Technical Field
The invention relates to the field of DHCP application, in particular to a lease time configuration method and a lease time configuration system for an IP address.
Background
With the continuous development of networks, the network scale is gradually enlarged and the types of bearer services are increasingly enriched. In an actual network environment, due to the mobility of terminal devices, the number of terminal devices, and the like, a dynamic IP Address (Internet Protocol Address) allocation mechanism is often required. The DHCP (Dynamic Host Configuration Protocol) is gradually and continuously developed to meet such demands. Currently, the DHCP protocol is widely used in operators and enterprise networking, mainly for dynamic allocation and management of IP addresses. The DHCP protocol participant comprises a DHCP Client, a DHCP Relay and a DHCP server, and the protocol implementation process usually comprises five steps: firstly, a DHCP Client sends a query message to search a DHCP set; secondly, the DHCP Server replies the received DHCP Client inquiry message through a response message; thirdly, the DHCP Client receives the replies of the plurality of DHCP servers and selects one DHCP server according to the strategy; fourthly, the DHCP Client sends a request message to the selected DHCP server; and fifthly, the DHCPSever sends a confirmation message to the DHCP Client. Thereby completing the east-dai allocation process of the address. The response message sent by the DHCP server to the DHCP Client in the second step is a pre-allocation message of the DHCP server, and usually includes information such as an IP address planned to be allocated and lease time. After the lease time expires, the DHCP Client needs to reinitiate the dynamic address allocation request.
Currently, in network implementation, lease time of an IP address is usually configured by default or by equipment in a unified manner. However, in network planning and application, an operator network is usually shared by multiple types of users and multiple services coexist. Different service types are different in the characteristics of address stability requirements, and if uniform IP address lease time limitation is adopted, the following defects exist: on one hand, for services with the requirement on address lease time parameters shorter than the configuration value, the IP address is not released in time, and the waste of the IP address is caused. On the other hand, for services with address lease time parameter requirements longer than the configuration value, the interaction times of IP application are additionally increased, and time delay brought by communication between the DHCP Client and the DHCP set is introduced.

Currently, in network implementations, lease time of an IP address is usually configured by default or by device in a unified manner. However, in network planning and application, an operator network is usually shared by multiple types of users and multiple services coexist. Different service types are different in the characteristics of address stability requirements, and if uniform IP address lease time limitation is adopted, the following defects exist: on one hand, for services with the requirement on address lease time parameters shorter than the configuration value, the IP address is not released in time, and the waste of the IP address is caused. On the other hand, for services with address lease time parameter requirements longer than configuration values, the number of interaction times of IP application is additionally increased, and time delay brought by communication between the Client of the DHCP Client and the server of the DHCP server is introduced.
To solve the above problem, referring to fig. 1, an embodiment of the present invention provides a lease time configuration method for an IP address, which is applied to a DHCP server and includes:
101. and receiving an inquiry message of the DHCP client.
The query message comprises an address allocation request and a custom Option field, wherein the custom Option field is used for indicating the service type of the service used by the DHCP client.
102. And analyzing the query message to acquire the service type and the address allocation request of the service used by the DHCP client.
103. And allocating a target IP address for the DHCP client according to the address allocation request.
104. And determining the lease time of the target IP address according to the service type and a preset rule.
Optionally, referring to fig. 2, the step 104 specifically includes:
1041. and searching a first target lease time corresponding to the service type from the first lease time table according to the service type, and determining the first target lease time as the lease time of the target IP address.
And the first lease time table comprises lease time corresponding to each service type.
Illustratively, when there are DHCP clients using services of the service type one and the service type two, a first IP address lease time and a second IP address lease time are respectively configured for the two DHCP clients according to the service types, the first IP address lease time is a lease time configured for an IP address allocated to the DHCP client using the service of the service type one, and the second IP address lease time is a lease time configured for an IP address allocated to the DHCP client using the service of the service type two.
10421. And selecting a first target lease time calculation formula corresponding to the service type from the first lease time calculation formula library according to the service type.
The first lease time calculation formula library comprises lease time calculation formulas corresponding to each service type.
Specifically, the first lease time calculation formula library includes at least two different lease time calculation formulas, for example:
the lease time calculation formula corresponding to the service type one is as follows:
wherein, the first IP address lease time is the lease time configured for the IP address allocated to the DHCP client terminal which uses the service and has the service type one, T11And T12Is a preset value, time is the current time, t1And t2The specific time is; t is t1And t2The specific time can be obtained according to the statistics of the service data of which the service type is the first service type, and the time period division in the specific formula can be specific to the DHCP of the service of which the use type is the first service type during busy time and idle timeThe client configures different IP address lease times; illustratively, assume that the current time is 13:00, t1Is 9:00, t2At 18:00, the lease time configured for the IP address assigned to the DHCP client using the service type one shall be T11。
The lease time calculation formula corresponding to the service type one is as follows:
wherein, the second IP address lease time is the lease time configured for the IP address which needs to be allocated to the DHCP client terminal using the service with the service type of two, T21And T22Is a preset value, time is the current time, t3And t4The specific time is; t is t3And t4The specific time can be obtained according to the statistics of the service data of which the service type is the service type two, and the time period division in the specific formula can configure different IP address lease times for the service DHCP client side of which the use type is the service type two aiming at busy time and idle time; t is the same for different services because busy and idle times are not necessarily the same3And t1May be the same or different, t4And t2May be the same or different.
Specifically, the idle busy hour of a certain service may be different time periods of each day, may be different time periods of each month, or may be different time periods of each year, so the time may be for the time of each day, for example, 8:00, may be for the time of each month, for example, zero fifteen of this month, or may be for the time of each year, for example, zero of this month, seven months, and one day of this year; in addition, busy hours of a certain service are not only just divided into two sections in each unit time period (day, month, year, etc.) like the above formula, but also a plurality of busy hours and a plurality of idle hours exist, so that each lease time calculation formula can be divided into a plurality of situations in practice, not only into two situations as in the above formula; again, the lease time value, e.g., T, resulting from the above equation11The calculation formula is obtained according to actual statistics, or may be a specific calculation formula of lease time related to the current time, which is obtained through statistics, for example, the formula (1) may be:
the first IP address lease time is a time/b; (3)
wherein a and b are parameter values obtained by actual statistics, and the specific numerical value is determined according to the actual statistical result; it should be noted that, for example only, the formula obtained by actual statistics may be more complex, and the above formula (3) does not have an actual acceptance value.
10422. And calculating the lease time of the target IP address according to the current time and a first target lease time calculation formula.
Optionally, in multiple situations of services in practice, some services may directly determine lease time of a required IP address according to a service type, and other services further select a specific lease time calculation formula according to the service type and then determine lease time of the required IP address according to a current time and the lease time calculation formula, so as shown in fig. 3, the step 104 specifically includes:
10431. and when the service type is the first type of service type, searching a second target lease time corresponding to the service type from the second lease time table according to the service type.
And the second lease time table comprises lease time corresponding to each service type in the first type of service types.
10432. The second target lease time is determined as the lease time for the target IP address.
10441. And when the service type is the second service type, selecting a second target lease time calculation formula corresponding to the service type from a second lease time calculation formula library according to the service type.
The second lease time calculation formula library comprises lease time calculation formulas corresponding to each service type in the second service types; for the case of the specific lease time calculation formula, reference may be made to the foregoing specific description of step 10421 in fig. 2, and details are not repeated here.
10442. And calculating the lease time of the target IP address according to the current time and a second target lease time calculation formula.
Optionally, in practice, the lease time is determined not only by selecting different lease time calculation rules according to different service types in step 104 shown in fig. 3 (one is to determine the lease time directly according to the service type, and the other is to select different lease time calculation formulas according to the service type, and then determine the lease time according to the selected lease time calculation formula at the present moment); or, different lease time calculation rules may be selected according to the current time, specifically, as shown in fig. 4, the step 104 specifically includes:
10451. and when the current time is determined to be in the first time period, searching a third target lease time corresponding to the service type from the third lease time table according to the service type.
And the third lease time table comprises lease time corresponding to each service type.
10452. The third target lease time is determined as the lease time for the target IP address.
10461. And when the current moment is determined not to be in the first time period, selecting a third target lease time calculation formula corresponding to the service type from a third lease time calculation formula library according to the service type.
And the third lease time calculation formula library comprises lease time calculation formulas corresponding to each service type.
Specifically, the library of third lease time calculation formulas may refer to the specific description for step 10421 in fig. 2, except that the first period in step 10461 may be a continuous period, for example, the first period may be 8:00-19: 00; or may be discrete time periods, such as, for example, a unit time period of days, the first time period being 8:00-9:00, 10:00-12:00, and 14:00-16: 00; therefore, in each lease time calculation formula in the third lease time calculation formula library in 10461, for the time division, instead of dividing each unit time period (day, month, year) into two or more time periods which may form one unit time period, the time period other than the first time period in each unit time period is divided into two or more time periods, for example, taking formula (1) in 10421 as an example, if the unit time period is day and the first time period is 8:00-19:00, the formula in 10461 may be specifically:
wherein, t5Is 19:00, t6Is 00:00, t7Is 8:00, T31And T32The lease time value obtained for statistics.
10462. And calculating the lease time of the target IP address according to the current time and a third target lease time calculation formula.
It should be noted that the steps 104 shown in fig. 2, 3 and 4 can be combined within a reasonable range to generate a new lease time scheme for determining the target IP address;
for example, after the steps 10431 and 10441, a step may be added to determine the current time, if the current time is in the preset time period, the lease time is determined from the lease time table according to the service type, if the current time is not in the preset time period, the lease time is calculated after the formula is determined from the lease time calculation formula library according to the service type, where the formula in the lease time formula library may refer to the expression in the step 10461;
for another example, after the steps 10451 and 10461, a step of judging the service type may be added, if the service type is the first type, the lease time is determined from the lease time table according to the service type, if the service type is the second type, the lease time is calculated after the formula is determined from the lease time calculation formula library according to the service type, wherein the formula in the lease time formula library may refer to the expression in the step 10461; specific schemes can be obtained by referring to the foregoing description, and are not described in detail herein.
105. And encapsulating the target IP address and the lease time thereof in a response message corresponding to the query message and sending the response message to the DHCP client.
Illustratively, the response message is an offer message, and the lease time of the IP address is specifically encapsulated in an option51 field in the offer message.
106. And receiving a request message sent by the DHCP client, and generating a confirmation message according to the request message.
The request message is at least used for requesting permission to use the target IP address, and the use time is lease time of the target IP address.
107. And sending the confirmation message to the DHCP client so that the DHCP client uses the target IP address according to the lease time of the target IP address.
The lease time configuration method of the IP address provided by the embodiment of the invention is applied to a DHCP server side and comprises the following steps: receiving a query message of a DHCP client, wherein the query message comprises an address allocation request and a user-defined Option field, and the user-defined Option field is used for indicating the service type of a service used by the DHCP client; analyzing the query message to acquire the service type of the service used by the DHCP client; allocating a target IP address for the DHCP client according to the address allocation request, and determining lease time of the target IP address according to the service type and a preset rule; packaging the target IP address and lease time thereof in a response message corresponding to the query message and sending the response message to the DHCP client; receiving a request message sent by a DHCP client, and generating a confirmation message according to the request message; the request message is at least used for requesting permission to use the target IP address and the use time is lease time of the target IP address; and sending the confirmation message to the DHCP client so that the DHCP client uses the target IP address according to the lease time of the target IP address. According to the technical scheme provided by the embodiment of the invention, after receiving the query message of the DHCP client, the query message is analyzed to obtain the address allocation request of the DHCP client and the service type of the service used by the DHCP client, and then the lease time of the target IP address is determined according to the service type of the service used by the DHCP client and the preset rule except that the target IP address is allocated to the DHCP client according to the address allocation request; then packaging the target IP address and lease time thereof in a corresponding message and sending the message to the DHCP client; and finally, after receiving the request message of the DHCP client, sending a corresponding confirmation message to enable the DHCP client to use the target IP address according to the lease time of the target IP address. According to the technical scheme provided by the embodiment of the invention, the corresponding lease time can be set for the IP address allocated to the DHCP client according to the preset rule aiming at the service type, the lease time corresponding to different service types is different, and the problems that the lease time of the existing IP address is a uniform fixed value, some DHCP clients needing to use the IP address for a long time generate a plurality of interactive processes of IP address application because the lease time is not enough and some DHCP clients needing to use the IP address for a short time occupy a certain IP address but do not use the same are avoided. Thereby achieving the effect of improving the utilization efficiency of the IP address.
