Description

Method, apparatus and system for suppressing redundant interaction of access node control protocol

technical field

The invention relates to the field of network communication, in particular to a method, device and system for suppressing redundant interaction of access node control protocols.

Background technique

Access Node Control Protocol (Access Node Control Protocol, ANCP) provides network access server (Network Access Server, NAS, such as broadband access server equipment) and access node (Access Node, AN, such as digital subscriber line access complex A channel for controlling information transmission between user devices. ANCP is carried by the third version of General Switch Management Protocol Version 3 (GSMPv3), and GSMPv3 has been expanded to increase the establishment and maintenance mechanism of the adjacency relationship.

The ANCP system usually consists of the following systems and equipment:

AN: Interact with NAS through ANCP protocol. Responsible for sensing the status and parameters of the access line, and reporting it to the NAS; implementing the line control strategy issued by the NAS, and OAM (Operation Administration and Maintenance, OAM) detection.

NAS: Responsible for obtaining access line parameters from the AN and reporting them to the AAA server; sending control policies and OAM detection commands to the AN.

Authentication, authorization and accounting server (Authentication, Authorization, AccountingSERVER, AAA server): used for authentication, authorization and accounting of access services. It interacts with the NAS through protocols such as RADIUS (Remote Authentication Dial In UserService) and Terminal Access Controller Control System (TACACS, Terminal Access Controller Access Control System).

Policy server (POLICY SERVER, POLICY server): Provide users with the service of "selecting services on demand". The POLICY server completes user service configuration, policy decision-making, service billing, etc. and other protocols to interact with the NAS.

After the adjacency relationship is established, the AN monitors the line status of the user line on the access side, and defines the active line identification (identity, ID, ANCP protocol as Access-Loop-Circuit-ID), standard (the user line accessed by the AN Type, such as ADSL, VDSL), uplink and downlink bandwidth, uplink and downlink maximum rate and other information are reported to the NAS through the ANCP protocol. When the line information changes, the AN notifies the NAS to update the relevant line information through the ANCP protocol. When a user on the corresponding line under the AN goes online, the NAS performs bandwidth control and traffic supervision on the service of the user on the line according to the previously saved line ID. When a user goes online or customizes a service, the RADIUS server can deliver the corresponding line policy to the NAS according to the corresponding line information, and the NAS sends the policy to the corresponding AN, and the AN applies the policy. The NAS can also send an OAM detection message to the AN through the ANCP protocol. After receiving the message, the AN will perform a loopback detection on the corresponding line and feed back the detection result to the NAS through the ANCP protocol.

When the AN senses that a user's line has changed, it will report the message to the NAS through the ANCP protocol message, and at the same time, the NAS will also report the message to the remote server after receiving the user's line change message reported by the AN ( such as a RADIUS server) to modify the user's information.

NAS supports a large number of users. When AN and users negotiate bandwidth, AN will report a large amount of user line bandwidth update information to NAS, which will cause NAS to fail to process it in time, or fail to report it to the remote server in time. Correspondingly, NAS It will also repeatedly send a large number of redundant line configuration and OAM detection messages to the AN, causing the AN to fail to process normal messages in a timely manner.

Contents of the invention

Detailed ways

Embodiment 1 of the present invention is provided below with reference to FIG. 1 and FIG. 2 .

FIG. 1 is a flowchart of a method for suppressing redundant interaction of an access node control protocol according to Embodiment 1 of the present invention. The method includes:

101. Record the current ANCP information. The ANCP information may include one or more of user line information, line configuration messages, and OAM detection messages. When recording the OAM detection message, record the receiving time of the OAM detection message. The user line information may include one or more of user uplink bandwidth information, user downlink bandwidth information, user uplink maximum rate, and user downlink maximum rate. The specific information included can be pre-set according to actual needs, or set by the server or network management equipment, or specified by network management personnel.

102. Receive ANCP update information. When AN finds that the user line changes and sends user line update information, the redundant interaction suppression device receives the update information of the user line information from AN; when the NAS updates the line configuration of AN, the redundant interaction suppression device receives the line configuration from NAS Message update information: when the NAS sends an OAM detection message, the redundant interaction suppression device receives the OAM detection message from the NAS, and uses the receiving time of the OAM detection message as the update value of the ANCP update information.

103. Calculate the difference between the ANCP update information and the current ANCP information. For the user line information or the line configuration message, the difference is the change amount of the user's uplink and downlink bandwidth, the change amount of the user's uplink maximum rate or the change amount of the line configuration information. For the OAM detection message, the difference is the time difference between the time when the redundant interaction suppression device receives the OAM detection message and the time when a new OAM detection message is received.

104. Determine whether the difference calculated in 103 satisfies a preset threshold. If the difference meets the preset threshold, go to step 105, otherwise go to step 102. The difference meeting the preset threshold may be that the difference is greater than the preset threshold or the difference is greater than or equal to the preset threshold. The preset threshold can be fixed, or dynamically issued by the server or network management equipment, and can also be modified by equipment operation and maintenance personnel at any time according to different situations. These preset threshold setting methods can also be used in combination. For example, first Set according to a certain experience value, and if there is a deviation, then perform specific dynamic adjustments. The dynamic adjustments can be dynamically issued by the server or network management equipment, or can be modified by equipment maintenance personnel.

105. Send ANCP update information and record the updated ANCP information. When the difference between the update information of the user line information and the current user line information satisfies the preset threshold, the redundant interaction suppression device sends the update information of the user line information to the NAS, and records the sent update information of the user line information as the current ANCP information; when the difference between the update information of the line configuration message and the current line configuration message meets the preset threshold, the redundant interaction suppression device sends the newly received line configuration message to the AN, and records the update information of the sent line configuration message, As the current ANCP information; when the difference between the update information of the receiving time of the OAM detection message and the receiving time of the currently recorded OAM detection message satisfies a preset threshold, the redundant interaction suppression device sends a newly received OAM detection message to the AN, And record the update information of the receiving time of the sent OAM detection message as the current ANCP information. After executing step 105, it may return to continue executing step 102.
