A network traffic manager receives, from an ingress port in a group of ingress ports, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the group of ingress ports has been assigned a token for the queue. Upon determining that the group of ingress ports has been assigned the token, the manager determines that other cells of the packet are stored in the buffer, and accordingly stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells to the buffer queue or a copy generator queue, and releases the token from the group of ingress ports.
