<p>The present invention discloses a method of implexmenting bandwidth multiplexing on the same virtual container-trunk(VC-trunk) in a Metropalitan Area device, It comprises: A) Determines weather the size of the first packet in the current queue on the sent side of the VC-trunk is less than or equal to the quantum value of the deficit counter for this queue, If the size of the first packet in the current queue on the sent side of the VC-trunk is less than or equal to the quantum value of the deficit counter for this queue, the packet is sent on the trunk at first, Then sets the quantum value of the deficit counter to be equal to the differece between the current quantum value of the deficit counter and the size of the packet, and then determines weather the queue is empty, If the queue is empty, the queue is deleted from the active queue, and performs step B, If the queue is not empty, It goes back step A; If the size of the packet is larger than the current quantum value of the deficit counter, and sets the quantum value of the deficit counter to be equal to the sum of the quantum value of the deficit counter and the increase by degrees; B) Rounding robin for the next active queue, and goes back step A. The present invention implements to share bandwidth and multiplex stat, and improves the bandwidth utilizing ratio.</p> |
