Abstract
A system for processing routing according to priorities of logical interfaces is provided. The system includes a priority setting unit for setting priorities of a plurality of logical interfaces set in a physical interface, and a priority scheduler for determining a priority of a respective logical interface from an input frame, and for outputting the input frame to a driver queue of the physical interface when the input frame is output from a logical interface having the highest priority. Traffic burstiness caused by queuing can be reduced in a network routing system employing at least one logical interface.
Claims13
A routing system in which at least one logical interface is set in a physical interface, the system comprising:
- a priority setting unit for setting priorities of a plurality of logical interfaces set in a physical interface;
- a priority scheduler for determining a priority of a respective logical interface from an input frame, for outputting the input frame directly to a driver queue of the physical interface when the input frame is output from a logical interface having the highest priority without first outputting the input frame to an internal queue of the physical interface, and for outputting the input frame to the driver queue via the internal queue of the physical interface when the input frame is output from a logical interface that does not have the highest priority;
- and
- a frame measurer controlled by a feedback processor, for setting a frame processing capacity of the internal queue based on a measured available bandwidth of frames to the driver queue.
A method for controlling a system for processing routing according to priority of logical interfaces, the method comprising:
- setting priorities of a plurality of logical interfaces;
- determining whether a logical interface transmitting an input frame has the highest priority;
- when the input frame is output from the logical interface having the highest priority, directly outputting the frame to a driver queue of a physical interface without first outputting the frame to an internal queue of the physical interface;
- and
- when the input frame is not output from the logical interface having the highest priority, outputting the frame to the driver queue via the internal queue,
- wherein a frame processing capacity of the internal queue is set by a frame measurer under the control of a feedback processor based on a measured available bandwidth of frames to the driver queue.
