The method that this instance provides is equally applicable to the situation that multistage bandwidth is consulted, and when clean culture, RACS need confirm respectively that the corresponding unicast bandwidth of each level all wants enough could admit the user to watch the clean culture video; When not having enough bandwidth, and need use bandwidth, guarantee that clean culture can carry out smoothly to the not enough multicast bandwidth management equipment of unicast bandwidth.If RACS uses the bandwidth failure to some multicast bandwidth management equipments, then refusing user's is watched the clean culture video.Also similar for multicast, whether each level all need confirm self to have enough multicast bandwidth to admit the new group broadcasting video frequency request of user respectively, if not enough, each level all needs to use bandwidth to RACS respectively; If the bandwidth of using of any one level is failed, user's multicast request can be rejected.

The method that present embodiment provides; Need confirm respectively through RACS whether the pairing residue unicast bandwidth of each level multicast bandwidth management equipment is enough; Promptly whether be reserved with enough unicast bandwidth; And need use multicast bandwidth to the not enough corresponding level multicast bandwidth management equipment of residue unicast bandwidth, guarantee with the pairing residue unicast bandwidth of each level multicast bandwidth management equipment all enough.If RACS uses the multicast bandwidth failure to a certain level multicast bandwidth management equipment, then user's clean culture video request can be rejected.Also similar for multicast, whether each level multicast bandwidth management equipment all need confirm self to have enough residue multicast bandwidth to admit the new group broadcasting video frequency request of user respectively, if not enough, then need use unicast bandwidth to RACS; If arbitrary level multicast bandwidth management equipment is used the unicast bandwidth failure to RACS; User's multicast request will be rejected; Consult through the bandwidth between unicast bandwidth management equipment and the multicast bandwidth management equipment; Thereby effectively improved bandwidth utilization, satisfied the bandwidth adjustment demand of operator.
