    • The present invention relates to methods and arrangements for access control in a multicast system when data is distributed from a source VS on a common link L3 to at least two users U1- U12 via a node BN21 that comprises a request arbiter ARB21. The arbiter is arranged to distribute the data from source to the users. The method comprises the following steps: - A weight is assigned to each user U1-U12 associated with the node BN21. The weights determine each user's allowed bandwidth i.e. bandwidth allowed to use out of available bandwidth on the common link L3. - A request to join a multicast session S81 is received to the node BN21 from a user U1. - Actual bandwidth usage by the user U1 calculated as the sum of the user's bandwidth part of each used session on the common link L3 including the new request, is compared in the node BN21 with the users U1 allowed bandwidth. - The request denied if the available bandwidth is lower than the actual bandwidth. ® KIPO & WIPO 2007
    • 本发明涉及当通过包括请求仲裁器ARB21的节点BN21将数据从公共链路L3上的源VS分发到至少两个用户U1-U12时,多播系统中的接入控制的方法和装置。 仲裁器被安排为将数据从源分发给用户。 该方法包括以下步骤: - 将权重分配给与节点BN21相关联的每个用户U1-U12。 权重确定每个用户的允许带宽,即允许在公共链路L3上使用可用带宽的带宽。 - 加入多播会话S81的请求从用户U1接收到节点BN21。 - 在节点BN21中与用户U1允许的带宽比较由用户U1在包括新请求的公共链路L3上的每个使用的会话的用户的带宽部分的和之间的实际带宽使用。 - 如果可用带宽低于实际带宽,请求被拒绝。 ®KIPO&WIPO 2007
