摘要

A method and device for implementing multicast connection admission control is provided, and the method includes: calculating a currently remaining multicast support capability of a network-side functional unit upon receiving a program request initiated from a user; and admitting an access of the user when a support capability required for a program as requested by the user is below or equal to the currently remaining multicast support capability of the network-side functional unit.
