Method for transmitting policy information between network equipment

A method for transmitting policy information between network equipment, comprising:

• adding a Policy Information Transfer Protocol (PITP) type by extending protocol types of protocol messages on a layer between broadband user access equipment and a Broadband Remote Access Server (BRAS);
• transmitting, by a requester, the policy information to a responder with a PITP message;
• and
• confirming, by the responder the received message is the PITP message sent to the responder, and obtaining the policy information in the PITP message,
• wherein the PITP message comprises:
• a policy information transmission type field for distinguishing policy information transmission types, an operation type field for distinguishing operation types, and a policy information content field for bearing the policy information,
• wherein the policy information is physical port information of a user, the requester is the BRAS, and the responder is the broadband user access equipment,
• wherein the method, before the step of the requester transmitting the policy information to the responder with a PITP message, further comprises:
• the BRAS detecting that the user logs in and the user is preparing or starting to initiate an authentication request,
• wherein the step of the requester transmitting the policy information to the responder with a PITP message comprises:
• the BRAS setting the policy information transmission type field of the PITP message to be port information inquiry, setting the operation type field to be inquiry request, setting a layer-2 MAC address of the inquired user in the policy information content field;
• and
• the BRAS sending the PITP message to the broadband user access equipment,
• wherein the step of the responder obtaining the policy information in the PITP message comprises:
• after finding that the policy information transmission type field is port information inquiry and the operation type field is inquiry request, the broadband user access equipment obtaining the layer-2 MAC address of the inquired user from the policy information content field of the message, and
• wherein the method, after the step of the responder obtaining the policy information in the PITP message, further comprises:
• according to the layer-2 MAC address of the inquired user, the broadband user access equipment obtaining the physical port information of the user;
• the broadband user access equipment sending to the BRAS a PITP message, in which the policy information transmission type field is set to be port information inquiry, the operation type field is set to be inquiry confirmation, and the policy information content field comprises the obtained physical port information of the user;
• the BRAS confirming that the received message is a PITP message sent to the BRAS;
• and
• after finding that the policy information transmission type field is port information inquiry and the operation type field is inquiry confirmation, the BRAS obtaining the physical port information of the user from the policy information content field of the PITP message.

• wherein the policy information is configuration maintenance information, the requester is the BRAS, and the responder s the broadband user access equipment,
• wherein the method, before the step of the requester transmitting the policy information to the responder with a PITP message, further comprises:
• the BRAS entering the configuring and managing mode for the broadband user access equipment that is to be configured and maintained,
• wherein the step of the requester transmitting the policy information to the responder with a PITP message comprises:
• the BRAS setting the policy information transmission type field of the PITP message to be configuration maintenance, setting the operation type field to be data configuration and/or data inquiry, setting the configuration maintenance information in the policy information content field;
• and
• the BRAS sending the PITP message to the broadband user access equipment,
• wherein the step of the responder obtaining the policy information in the PITP message comprises:
• after finding that the policy information transmission type field is configuration maintenance and the operation type field is data configuration and/or data inquiry, the broadband user access equipment obtaining the configuration maintenance information from the policy information content field of the message,
• wherein the method, after the step of the responder obtaining the policy information in the PITP message, further comprises:
• the broadband user access equipment completing the data configuration and/or data inquiry according to the configuration maintenance information;
• the broadband user access equipment returning to the BRAS a PITP response message, in which the policy information transmission type field is configuration maintenance, the operation type field is data configuration response and/or data inquiry result, and the policy information content field comprises the data configuration response information and/or the data inquire result information;
• and
• after finding that the policy information transmission type field in the PITP response message is configuration maintenance and the operation type field is data configuration response and/or data inquiry result, the BRAS obtaining the data configuration response information and/or the data inquiry result information from the policy information content field.
