A method for transmitting the policy information between the network devices

摘要

A method for transmitting policy information between network equipment, extending protocol types of messages in layer-2, layer-3 or a higher application layer between an IP-uplink broadband user access equipment and a BRAS so as to construct a PITP, and utilizing the PITP to bear policy information; a PITP message includes a policy information transmission type field, an operation type field and a policy information content field, and different types of policy information are distinguished by the policy information transmission type field; transmission of the policy information is implemented through a point-to-point means or a broadcast means in layer-2, a unicast or a multicast in layer-3 or a higher application layer. The present invention implements the transmission of policy information, prevents account intrusions and hacker attacks, makes it convenient for the broadband user access equipment to implement dynamic QoS policy adjustment in terms of different users and makes it easy for integrated managing the online equipment.
