Packet forwarding system having a control packet processor which allocates the bandwidth for a control packet adaptively and processing method thereof

A control packet management device of a packet forwarding system, comprising:

• a packet queue having a plurality of queues to store control packets as transmitted;
• a first processor to transmit at least one of said control packets stored in one queue of said plurality of queues to a host by a one-to-one interrupt;
• a second processor to divide said at least one of said control packets stored in said one queue into groups of a predetermined size and transmit said at least one of said control packets to said host in a group unit and by direct memory access (DMA);
• a third processor to discard a most common type of said at least one of said control packets stored in said one queue;
• and
• a controller to control said first, second and third processors to selectively operate in accordance with an accumulation state of said control packets stored in said plurality of queues, wherein
• said controller stores the rest of said control packets other than the discarded control packets to another queue of said plurality of queues.
