Digital subscriber line user capacity estimation
First Claim
1. A system comprising:
- an asynchronous transfer mode (ATM) switch responsive to a network; and
a digital subscriber line access multiplexer (DSLAM) coupled to the ATM switch and to a plurality of digital subscriber lines, the DSLAM to support the plurality of digital subscriber lines, the DSLAM configurable to limit a number of supported digital subscriber lines based on an estimated capacity model, the estimated capacity model including a data transmission slowdown indicator comprising a probability of experiencing a slowdown event.

Abstract
In a particular embodiment, the present disclosure is directed to a data communications system. The data communication system includes a plurality of digital subscriber lines, a digital subscriber line multiplexer coupled to each of the plurality of digital subscriber lines, and a data switch coupled to the digital subscriber line multiplexer via a communication link. The data communications system is configured such that the number of digital subscriber line users supported by the digital subscriber line multiplexer is determined based on an estimated maximum number of users, the estimated maximum number of users determined based on an average peak bandwidth per user value, a data communication capacity of the communication link, and a data transmission slowdown indicator. The communication capacity is based on a user type selected from a set of available user types.

8. A method comprising:
-
selecting a first user type and a second user type from a set of available user types, each user type of the set of available user types including an associated constant bandwidth, wherein a first bandwidth of the first user type is different from a second bandwidth of the second user type;
determining a first average peak bandwidth based on the first user type and a second average peak bandwidth based on the second user type;
estimating a first percentage of customers comprising the first user type and a second percentage of customers comprising the second user type;
determining probability of slowdowns associated with the first percentage and associated with the second percentage; and
estimating a number of users of the first type and the second type at least partially based on the probability of slowdowns and an average peak bandwidth per user type. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
