Abstract

The present invention discloses a method, system, and device for admission control and pertains to the communications field. The method includes: admitting a subscriber for watching a multicast video only if each multicast bandwidth management device has sufficient remaining bandwidth after receiving a multicast video request from the subscriber; refusing the subscriber for watching the multicast video if any multicast bandwidth management device has insufficient bandwidth and fails to borrow bandwidth from a unicast bandwidth management device; and after receiving a unicast video request from the subscriber, admitting the subscriber for watching a unicast video only if remaining unicast bandwidth corresponding to a multicast bandwidth management device in each level is sufficient, or else, refusing the subscriber for watching the unicast video. Through bandwidth negotiation between the unicast bandwidth management device and each multicast bandwidth management device, admission control is implemented.

Claims8

Dependent claims

A method for admission control, comprising:

receiving, by a multicast bandwidth management device, a multicast video request from a subscriber, and judging whether available multicast bandwidth satisfies a requirement of the multicast video request;
refusing the subscriber for watching a multicast video if the available multicast bandwidth does not satisfy the requirement of the multicast video request;
judging whether an upper level device exists if the available multicast bandwidth satisfies the requirement of the multicast video request;
if the upper level device exists, forwarding the multicast video request from the subscriber to the upper level device, so that whether to admit the subscriber for watching the multicast video is determined by the upper level device;
and
if no upper level device exists, admitting the subscriber for watching the multicast video;
wherein the judging whether the available multicast bandwidth satisfies the requirement of the multicast video request comprises:
determining that the available multicast bandwidth satisfies the requirement of the multicast video request when managed remaining multicast bandwidth does not satisfy the requirement of the multicast video request, but unicast bandwidth is successfully borrowed from a unicast bandwidth management device.

A method for admission control, comprising:

receiving, by a unicast bandwidth management device, a unicast video request from a subscriber, and judging whether available unicast bandwidth corresponding to a multicast bandwidth management device in each level satisfies a requirement of the unicast video request;
if the available unicast bandwidth corresponding to the multicast bandwidth management device in each level satisfies the requirement of the unicast video request, admitting the subscriber for watching a unicast video;
and
if the available unicast bandwidth corresponding to the multicast bandwidth management device in each level does not satisfy the requirement of the unicast video request, refusing the subscriber for watching the unicast video;
wherein the judging whether the available unicast bandwidth corresponding to the multicast bandwidth management device in each level satisfies the requirement of the unicast video request comprises:
determining that the available unicast bandwidth corresponding to the multicast bandwidth management device in each level satisfies the requirement of the unicast video request when managed remaining unicast bandwidth corresponding to at least one multicast bandwidth management device in a level does not satisfy the requirement of the unicast video request, but multicast bandwidth is successfully borrowed from a multicast bandwidth management device in a corresponding level.
