Abstract:
1. A system for implementing performance management between a Residential Gateway (RG) and a Broadband Remote Access Server (BRAS), comprising: a Digital Subscriber Line Access Multiplexer (DSLAM) connected to the RG and to the BRAS, respectively, wherein: the DSLAM further comprises an interworking function Operation, Administration and Maintenance InterWorking Function (OAM IWF) for a Protocol conversion between a performance management message of an Asynchronous Transfer Mode (ATM) OAM protocol or a point-to-point Ethernet OAM protocol of the Digital Subscriber Line (DSL) domain between the RG and the DSLAM and a performance management message of the service layer Ethernet OAM protocol between the DSLAM and the BRAS, wherein the performance management comprises performing a parameter test of service level agreement (SLA) or reporting the statistical parameters information of a traffic flow; an RG-connected DSL identifier is configured in a DSL port of the DSLAM; the DSLAM determines an RG according to the RG-connected DSL identifier carried in the performance management message; the end-to-end performance management between the determined RG and the BRAS is performed according to the performance management message of the converted protocol; and wherein: when the performance management comprises performing the parameter test of SLA, the BRAS sends a performance management request message of the service layer Ethernet QAM protocol carrying the RG-connected DSL identifier to the DSLAM; the DSLAM converts the performance management request message into a loopback message of the ATM OAM protocol or the point-to-point Ethernet OAM protocol through the configured OAM IWF; the DSLAM determines the RG according to the RG-connected DSL identifier carried by the message and sends the loopback message to the determined RG; the RG receiving the loopback message performs the DSL performance test and sends a response message for the loopback message of the ATM OAM protocol or the point-to-point Ethernet OAM protocol by which the DSL performance test result is carried to the DSLAM; and upon performing the protocols conversion to the response message through the configured OAM IWF, the DSLAM obtains a performance management response message of the service layer Ethernet OAM protocol carrying the DSL performance test result, and sends the obtained response message to the BRAS.
