Abstract: A method and apparatus for per connection queuing of multicast transmissions. The method begins by receiving a cell associated with a multicast transmission. A multicast transmission typically includes a single ingress connection and a plurality of egress connections. The processing then continues by queuing the cell in a next available cell buffer of a root queue that is associated with the multicast transmission. Next, a determination is made as to whether a predetermined number of leaf queues (i.e., queues associated with egress queue identifiers) associated with the multicast transmission are empty when the queuing of the cell commences. Each of a plurality of leaf queues is associated with a corresponding one of the egress connections of the multicast transmission. A leaf queue will be empty when the corresponding egress connection has transported all of the data cells contained within the root queue associated with the multicast transmission.
