Description

Access network port resource management method, device and system

technical field

The present invention relates to the communication field, in particular to a method, device and system for managing access network port resources.

Background technique

DSL technology is a high-speed transmission technology for data transmission through telephone twisted pair, that is, unshielded twisted pair, including asymmetrical digital subscriber line (Asymmetrical Digital Subscriber Line, ADSL), very high-speed digital subscriber line (Very-high- bit-rate Digital Subscriber Line (VDSL), ISDN Digital Subscriber Line (IDSL) based on Integrated Services Digital Network (ISDN), Single-pair High-bit- rate Digital Subscriber Line, SHD SL), the second-generation asymmetrical digital subscriber line (Asymmetrical Digital Subscriber Line 2, ADSL2), the second-generation asymmetrical digital subscriber line of the extended frequency band (Asymmetrical Digital Subscriber Line2plus, AD SL2plus), the second Generation of very high-speed digital subscriber line (Very-high-bit-rate Digital Subscriber Line 2, VDSL2) and so on.

Among the various network layers of DSL, the access network is the layer closest to the user, and plays the role of connecting the user terminal equipment into the network in the last few kilometers. The current access network equipment can usually be divided into central office (CO, Central Office) equipment and customer end (CPE, Custom Premise Equipments) equipment. In existing network applications, the central office equipment adopts a fixed method as the client Port configuration is performed on the device. For example, if you need to connect 100 client devices, you need to have 100 ports on the central office device. Regardless of whether a user is online or not, port resources must be reserved for it. However, in actual use, there is a certain convergence ratio between the number of connected client devices and the number of actual online users. The access device is generally about 80%, that is, 100 users are activated, and the actual maximum number of concurrent online users is only 80 users. That means that the physical port resources connected to the remaining 20 users are idle, but according to the existing solution, the operator can only install it for 100 users, resulting in a waste of port resources.

The first embodiment of the present invention is described in detail with a digital subscriber line network. As shown in FIG. The twisted pair is connected to the central office device 16 , and the user end device 12 can send messages to the central office device 16 , and can also receive and process messages sent by the central office device 16 .

The central office device 16 may specifically be a digital subscriber line access multiplexer (DSLAM, Digital Subscriber Line Access Multiplexer), a router (Router) or a switch (Switch), etc. The central office device 16 includes a housing (not shown), a service board 161, a monitoring board 162, a main control board 163 and an access network port resource management device 164, a service board 161, a monitoring board 162, a main control board 163 and an access The network port resource management device 164 is usually set in the housing of the central office equipment 16 for sending and receiving data. Among them, the service board 161 is used to provide service access ports for the user end equipment 12; the monitoring board 162 is used to monitor whether the user end equipment connected to the central office equipment is online; The control panel 163 can also cooperate with the line grabbing server to provide port resource allocation information for the access network port resource management device 164; the access network port resource management device 164 is used to dynamically allocate temporary access ports for the client equipment 12 For use by the client device 12.

As shown in FIG. 2 , the access network port resource management device 164 of the present invention specifically includes: a receiving unit 165 , a port allocation unit 166 and a port reclaiming unit 167 . Wherein, the receiving unit 165 is configured to receive a request message for requesting access to the network sent by the client device 12; the port allocation unit 166 is configured to dynamically allocate a temporary access port for the client device 12 according to the request message for the client device 12 Use; the port reclaiming unit 167 is used to reclaim the temporary access port dynamically allocated for the client device 12 when it is found that the client device 12 is offline, and make the access port enter an idle state.

In this embodiment, the monitoring board 162 and the access network port resource management device 164 are set in the housing of the central office equipment 16. Those of ordinary skill in the art should know that the monitoring board 162 can also be set in the access network according to actual needs. The interior of the network port resource management device 164 is shown in FIG. 3 .

In addition, as shown in FIG. 4 , the function of the line grabbing server in the first embodiment can also be integrated into the main control board 163 to realize direct management of the access network port resource management device 164 by the main control board 163 .

The access network port resource management method of the present invention is described in detail below in conjunction with FIG. 5:

First, in the central office equipment 16, add one or more line monitoring boards 162. Specifically, a chip that monitors the on-line of the client equipment 12 (such as a chip that monitors a certain frequency for sending signals) can be used or an existing high-density board 162 can be used directly. The commercial chip (24-way ADSL) performs 24*4=96-way monitoring boards, and the main control board 163 cooperates with the line grabbing server for processing. For example: the line grabbing server polls 96 ports each time for external lines, and each time takes 2 seconds. If the device supports a maximum of 1024 ports, it will take up to 22 seconds to monitor whether the client device 12 is online.

Step 30: The central office device 16 receives a request message from the client device 12 requesting to access the network.

Step 32: The central office device 16 dynamically allocates a temporary access port for the user-end device 12 according to the request message for the user-end device to use. In practical applications, the idle access port on the service board that is already in the power-on state can be preferentially selected port. The general principle of dynamic allocation is to make the resource deployment as centralized as possible. For example, the central office device 16 first checks whether there are idle access port resources on the activated service board, and allocates the idle access port resources to the user end equipment to be activated if there is any 12. If not, start a new service board, and allocate the idle access port resources on the service board to the user terminal equipment to be activated.

Step 34: The central office device 16 implements data transmission with the client device 12 through the dynamically allocated temporary access port.

Step 36: When the central office device 16 finds that the client device 12 is offline, the central office device 16 takes back the temporary access port dynamically allocated for the client device 12, and makes the access port enter an idle state.

Step 38: The central office device 16 aggregates the access ports that enter the idle state, that is, aggregates the access ports that enter the idle state to one service board as much as possible. When all ports on a certain service board are in the idle state , the energy-saving operation of powering off the idle service board or unloading the idle set is performed. For example, the number of supported ports on a service board of a certain central office device 16 is 24, and when the number of access ports in the idle state reaches 24, the 24 ports in the idle state can be concentrated on one service board. Then control the service board to power off or enter the energy-saving state.

As can be seen from the above embodiments, the present invention can dynamically allocate a temporary access port for the user end device according to the request of the user end device by setting the port allocation unit, and the central office device realizes communication with the user end device through the dynamically allocated temporary access port. The data transmission of the user end equipment. The present invention implements dynamic switching of physical port resources by setting a port allocation unit to realize flexible allocation of resources. This method can maximize the number of users supported by the central office equipment, give full play to the potential of the central office equipment, and significantly reduce the number of operators. The network construction cost and the user's network access fee.

In addition, the embodiment of the present invention can also aggregate the access ports that enter the idle state. When all the ports on a certain service board are in the idle state, the service board can be controlled to power off or enter the energy-saving state, which can obviously Reduce energy consumption and prolong the service life of service boards.

The above is the description of the specific embodiments of the present invention, and those skilled in the art can make appropriate improvements and changes to the solutions of the present invention during the specific implementation process to meet the needs of specific situations. Therefore, the specific embodiments of the present invention are only exemplary, and are not intended to limit the protection scope of the present invention.
