Address allocation method and equipment

Abstract

The invention discloses an address allocation method and equipment. The address allocation method includes that a BRAS records a virtual domain and the corresponding relationship between the virtual domain and one or more real domains; when the BRAS receives an address application message from terminal equipment, the BRAS confirms the virtual domain corresponding to the terminal equipment and selects one real domain from the real domains corresponding to the virtual domain; the BRAS confirms an IP address pool corresponding to the real domain, selects one unused IP address from the IP address pool and allocates the IP address to the terminal equipment. According to the embodiment, the number of IP addresses capable of being used can be extended without correcting any configuration on an AAA server and influencing the currently using users, and the phenomenon that the terminal equipment cannot obtain an IP address is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an address allocation method and equipment. Background technique [0002] With the continuous development of the Internet, people's demand for communication has gradually extended from traditional low-speed services such as telephone, fax, and telegraph to high-speed broadband services such as Internet access, video telephony, and video-on-demand. Higher and higher. At the same time, more and more users are connected to the MAN, and the service requirements of users are also expanding. The broadband MAN is facing the development trend of multi-service bearer network. In this case, in order to effectively manage and control the services of access users, prevent access users from occupying network resources such as network bandwidth and IP addresses without any restriction and control, and enable various services to be finely operated , resulting in BRAS (Broadband ...
