Description

Method and device for port allocation

technical field

The invention relates to the technical field of Internet communication, in particular to a port allocation method and equipment.

Background technique

With the continuous development of Internet communication technology, the number of users on the Internet is also increasing explosively. With the increasing number of network users, the current IPv4 public network address is quite tight. Therefore, NAT conversion will be performed when the operator exits, so as to assign a port number of an address to each user. Since the same address may be assigned to different users, the way to distinguish different users is to distinguish based on the assigned port number.

However, when a current user surfs the Internet, multiple applications connected to the Internet may be opened at the same time, such as HTTP web browsing, video services, BT downloads, FTP downloads, and the like. Operators often allocate ports according to the order in which users start applications. Since the port resources are limited, the applications started later may not be able to connect to the public network because they are not allocated to the port.

For example, when a user is performing HTTP web page browsing, video services, and BT download services at the same time, the BT download service will start multiple links to download together to download and upload faster, thus occupying more ports, which will lead to other more important users. The application cannot be used instead.

detailed description

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The implementations are only some of the implementations of the present application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

Fig. 1 is a flow chart of a port allocation method provided by the present invention. As shown in Fig. 1, the method may include the following steps.

Step S1: Prioritizing a preset number of services of the user in advance.

In this embodiment, each service can be assigned a corresponding priority according to the user's own service preference, and services with higher priority can enjoy the right to allocate ports first. Specifically, when the user goes online, the priority corresponding to each service may be recorded in the PPPoE login message.

In addition, in this embodiment, the priority thresholds corresponding to each service may also be generated according to the results of the user's classification of services in the broadband remote access server BRAS, and each service and the priority thresholds corresponding to each service may be stored in the data relationship table. Specifically, the size of the priority threshold may be determined according to the priority, and a service with a higher priority has a higher corresponding priority threshold. Table 1 is a data relationship table corresponding to service priority thresholds of different users.

Table 1 Data relationship table corresponding to service priority thresholds of different users

video business Web page BT other User A 70 100 10 30 User B 100 10 70 30 User C 70 10 100 10

It can be seen from Table 1 that user A sets the priority of the webpage service to the highest, and its corresponding priority threshold is 100, while the priority of the BT download service is set to the lowest by the device, and its corresponding priority threshold is 10.

Step S2: receiving a new session request, the new session request includes the target business to be created;

Step S3: Record the latest traffic time stamps corresponding to the services currently executed on each port.

In this embodiment, when a user needs to start a service when starting to surf the Internet, a session request can be created. The newly created session request may include the target service to be created. When the ports are sufficient, the ports can be allocated sequentially according to the creation time of the session request. When the service is executed on the port, the latest traffic time stamp corresponding to the service currently executed on each port can be recorded. The latest traffic time stamp may indicate the corresponding time point when the service last generates a flow, and the earlier the latest traffic time stamp, the longer the service is idle. Table 2 is a schematic table of recent traffic timestamps corresponding to different services.

Table 2 Schematic representation of recent traffic timestamps corresponding to different services

User A source port Assign port business type Last traffic time twenty one 100 FTP 2016-2-1 5:00 9000 101 BT 2016-2-1 4:00 19000 102 BT 2016-2-1 3:00

It can be seen from Table 2 that the BT download service corresponding to the port 102 stops running at 3 o'clock, and although the current port 102 is occupied, the corresponding service is not actually executed.

Step S4: If there is no idle port currently, determine the port to be released according to the divided priority and the latest recorded traffic time stamp.

In this embodiment, when all ports are occupied and there is no idle port currently, it is necessary to determine the service of the released port according to the priority corresponding to each service and the latest traffic time stamp. Specifically, in this embodiment, the service with the lowest priority among the currently executed services may be determined as the service of the port to be released, or the service with the earliest latest traffic time stamp among the currently executed services may be determined as the service of the port to be released. Among them, the lower the importance corresponding to the service with the lowest priority is, the less likely the user is to use the service. Therefore, the service with the lowest priority can be determined as the service of the port to be released. In addition, the service with the earliest time stamp of the latest traffic indicates that the service with the longest execution time has been stopped. Since the service has not been executed for a long time, the port corresponding to the service can be determined as the port to be released.

In this implementation manner, a weighted average method may also be used to accurately determine the port to be released by comprehensively considering the priority and the latest traffic time stamp. Specifically, first, according to the divided priority and the recorded latest traffic timestamp, a first reference value and a second reference value respectively corresponding to the priority and the latest traffic timestamp may be generated. Wherein, the first reference value may be a priority threshold as shown in Table 1, and the higher the priority, the greater the corresponding first reference value. The second reference value may be determined according to the time interval between the latest traffic timestamp and the current moment, and the larger the time interval, the smaller the second reference value. In this way, priority and recent traffic timestamps can be quantified. Next, according to the first reference value and the second reference value, the weighted average value corresponding to each port can be generated according to the following formula:

S=a·P+b·T

Wherein, S represents the weighted average value, a represents the weight coefficient corresponding to the first reference value, P represents the first reference value, b represents the weight coefficient corresponding to the second reference value, and T represents the weight coefficient corresponding to the first reference value. Two reference values.

In this embodiment, the two weighting coefficients in the above formula can be preset constants, so that the weighted average value corresponding to each port can be determined through the above formula, so that the port with the smallest weighted average value generated can be determined as The service of the port to be released.

Step S5: Disconnect the service in the determined port to be released, so as to release the occupied port, and execute the target service in the released port.

In this embodiment, after the port to be released is determined, the service in the determined port to be released may be disconnected, and the target service is executed on the released port. In this way, it can be ensured that the services preferred by users can still be executed even when the ports are fully occupied.

The present application also provides a port allocation device. Referring to Figure 2, the equipment can include:

The first division module is used to assign corresponding priorities to each service and record the corresponding priorities of each service in the PPPoE login message according to the service preferences preset by the user;

or

A weighted average determination module, configured to generate a weighted average corresponding to each port according to the following formula according to the first reference value and the second reference value:

S=a·P+b·T

Wherein, S represents the weighted average value, a represents the weight coefficient corresponding to the first reference value, P represents the first reference value, b represents the weight coefficient corresponding to the second reference value, and T represents the weight coefficient corresponding to the first reference value. Two reference values;

The port determination module is configured to determine the port with the smallest weighted average generated as the service of the port to be released.
