<p>It is presented a method for bandwidth allocation in a bandwidth allocation server of a digital videonetwork comprising a restricted channel being a link between a subscriber location and an access node. The method comprises: receiving a bandwidth reservation request to reserve bandwidth on the restricted channel, the bandwidth reservation request comprising a reservation start time; obtaining any existing bandwidth reservations for bandwidth on the restricted channel at least partly covered by the duration of the reservation request, the duration being delimited by the reservation start time; determiningwhether a bandwidth limit is exceeded by a combination of the bandwidth reservation request and the any existing bandwidth reservations, at any time covered by the bandwidth reservation request; when it is determined that the combination is under the bandwidth limit, handling an acceptance by sending a reservation accept response and storing a reservation corresponding to the bandwidth reservation request; and when it is determined that the combination exceeds the bandwidth limit, handling a rejection by sending a reservation reject response. A corresponding apparatus is also presented.</p> |
