Abstract
The invention provides an overload protection method for ACS based on token bucket which can effectively allocate the ACS resources and reduces the service pressure of the ACS. The method comprises the following steps: creating two token buckets in the ACS referred to as a full-speed token bucket and a half-speed token bucket wherein the full-speed token bucket is injected with a first level token and the half-speed token bucket is injected with a second level token; for the access request sent by a CPE device to the ACS, attempts are made to obtain the first level token from the full-speed token bucket; when the first level token is successfully obtained, then the full-speed TR069 request is executed; and the TR069 business is processed according to standard procedures; when the first level token fails to be obtained, another attempt is made to obtain the second level token from the half-speed token bucket; when the second level token is successfully obtained, then the half-speed TR069 request is executed to process the Inform information; and when the second level token fails to be obtained, the ACS outputs the HTTP 403 response indicating that the ACS denies the request.
Description
technical field [0001] The invention relates to the technical field of ACS systems, in particular to a token bucket-based ACS system overload protection method. Background technique [0002] CWMP (CPE WAN Management Protocol, CPE Wide AreaNetwork Management Protocol) is one of the technical specifications initiated and developed by the DSL (Digital Subscriber's Line, Digital Subscriber Line) Forum. The number is TR-069, so it is also called the TR-069 protocol. It provides a general framework, message specification, management method and data model for the management and configuration of home network devices in the next generation network. [0003] CWMP is mainly used in DSL access network environment. In the DSL access network, due to the large number of user equipment and scattered deployment, it is usually located on the user side, and it is difficult to manage and maintain the equipment. User-side equipment) for remote centralized management, solves the management dif...
