It should be noted that the dial-up server described in the embodiment of the present application includes a plurality of virtual dial-up ports, and different virtual dial-up ports can establish different dial-up lines to respond to a dial-up request and obtain an IP address, thereby effectively improving the efficiency of obtaining the IP address by the existing dial-up server.
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Example 1
Fig. 1 is a schematic flowchart of an IP address obtaining method according to an embodiment of the present application. The IP address acquisition method may be as follows. The execution subject of the embodiment of the present application may be a dial-up server (e.g., an ADSL server), or may be a network device for implementing a dial-up function, which is not limited herein.
Step 101: upon receiving a dialing request, at least one virtual dialing port for processing the dialing request is determined.
The dial server described in the embodiment of the present application is different from the dial server in the related art: in the embodiment of the present application, a plurality of virtual dial ports are arranged inside the dial server, and when the dial server receives a dial request, at least one virtual dial port may be triggered, or a plurality of virtual dial ports may be triggered to execute a dial operation.
Then when a dial request is received, it is further determined which virtual dial ports (at least one virtual dial port) to perform the dial operation.
Specifically, the working state of the controlled virtual dialing port is determined, wherein the working state comprises at least one of an idle state and a busy state;
and selecting the virtual dialing port with the working state being the idle state as the determined virtual dialing port for processing the dialing request.
Because each dial server is provided with a plurality of virtual dial ports, the number of the virtual ports responding to one dial request can be one or a plurality of, namely, one virtual dial port can respond to one dial request or a plurality of different virtual dial ports can respond to one dial request.
When the plurality of virtual dialing ports respond, the virtual dialing ports can be sequentially triggered to execute dialing operation according to the set dialing rule.
For example: assuming that the dialing rule is set to trigger one virtual dialing port every 30s, the dialing server triggers one virtual dialing port every 30s to execute dialing operation when receiving a dialing request. If the time of the received dialing request is T, triggering a virtual dialing port to execute a dialing operation at the time of T; and triggering one virtual dialing port to execute one dialing operation again at the moment of (T +30 s). It should be noted that the virtual dial ports at the interval of 30s may be the same virtual dial port, or may be different virtual dial ports, and this is not limited in detail here.
In addition, when a dialing request is received, the dialing server needs to further determine the current working state of each virtual dialing port, because the dialing request may have been received before the dialing request is received, then there will be some virtual dialing ports that are already performing dialing operations according to the dialing request that has been received before, that is, when the dialing request is received in step 101, some virtual dialing ports are in working states, and some virtual dialing ports are in idle states, so the dialing server may select the virtual dialing port that is in idle state as the determined virtual dialing port for processing the current receiving of the dialing request.
Optionally, when receiving the dialing request, the dialing server may select one virtual dialing port from the multiple virtual dialing ports according to a preset scheduling algorithm, as the determined virtual dialing port for processing the dialing request.
The scheduling algorithm described herein may be a Hash algorithm, or may be other algorithms, and is not limited in this respect.
Step 102: and indicating the determined virtual dialing port to execute dialing operation according to the dialing request to acquire an IP address.
In this embodiment of the present application, if the virtual dialing port for processing the dialing request is determined in step 101, a dialing instruction is sent to the determined virtual dialing port, so that the virtual dialing port executes a dialing operation according to the dialing request to obtain an IP address.
If the determined virtual dialing port is executing dialing operation, the dialing instruction sent to the virtual dialing port contains dialing time, namely when the dialing time is up, the virtual dialing port executes dialing operation according to the dialing request to acquire an IP address.
For example: the dialing server may calculate a dialing time (for example, 30s after the dialing operation is completed) for the virtual dialing port, and then the virtual dialing port first completes the executing dialing operation when receiving the dialing instruction, and executes the dialing operation according to the dialing request to obtain the IP address when the dialing time included in the dialing instruction arrives.
In another embodiment of the present application, after acquiring the IP address, the method further includes:
and storing the acquired IP address into an IP address set.
The IP address set comprises a mapping relation between the IP address and the obtained virtual dialing port number of the IP address, and/or the IP address set comprises the IP address, the obtained virtual dialing port number of the IP address and a mapping relation between the fixed port number of the dialing server.
Since the IP address acquired by the dial server when executing the dial operation may be the same as the IP address acquired before, when storing the acquired IP address in the IP address set, it is necessary to determine whether the IP address is the same as the IP address stored in the IP address set.
And if the IP address is different from the IP address stored in the IP address set, storing the obtained IP address into the IP address set.
And if the IP address is the same as the IP address stored in the IP address set, indicating the virtual dialing port to execute dialing operation again according to the dialing request and reacquiring the IP address.
It should be noted that the dialing request included in the "instructing the virtual dialing port to execute the dialing operation again according to the dialing request to reacquire the IP address" refers to the dialing request received in step 101, that is, once it is determined that the IP address acquired by the virtual dialing port is a duplicate IP address, the IP address acquired by the virtual dialing port may be notified to be duplicate, and at this time, the virtual dialing port may autonomously initiate the dialing operation to reacquire the IP address.
The form of the IP address set described in the embodiments of the present application may be an IP address list or an IP address library, and the form of the IP address set is not particularly limited herein.
According to the technical scheme provided by the embodiment of the application, a plurality of virtual dialing lines can be provided as a plurality of virtual dialing ports are arranged in the dialing server, so that a plurality of IP addresses can be obtained after the dialing server initiates dialing operation, and the efficiency of obtaining the IP addresses is effectively improved; meanwhile, the number of available IP addresses acquired by the dialing server is large, so that a subsequent central server can acquire different IP addresses, the problem that access requests are not processed due to fixed IP addresses in the prior art is effectively solved, and the utilization rate of system resources is effectively improved.

Assuming that the dial server shown in fig. 2 includes N virtual dial ports, each virtual dial port corresponds to one virtual network card, that is, the dial server includes N virtual network cards, when the dial server receives a dial request, the dial service is started, and the working states of different virtual network cards are determined, and assuming that M virtual network cards are in an idle state, the M virtual network cards can be instructed to execute dial operation to obtain an IP address.

In the embodiment of the application, when the number of the IP addresses contained in the IP address set is determined to be less than the set threshold value, the operation of selecting at least one dial server from the available dial server set can be triggered to be executed.
Specifically, since the IP address set includes a mapping relationship between the IP address and the obtained virtual dialing port number of the IP address, and/or the IP address list includes a mapping relationship between the IP address, the obtained virtual dialing port number of the IP address, and the fixed port number of the dialing server, when at least one dialing server operation is selected from the available dialing server set, the following manner may be adopted:
based on the virtual dialing port, the number of the IP addresses corresponding to the virtual dialing port can be determined, and if the number of the IP addresses corresponding to the virtual dialing port is smaller than a set threshold, the dialing server corresponding to the virtual dialing port can be used as the determined dialing server.
