The present invention relates to an adaptive interrupts coalescing system with recognizing minimum delay packets. The adaptive interrupts coalescing system of the invention comprises a first calculating device, a packet header parser, a second calculating device, and an interrupt controller. The first calculating device is used for calculating packet information of a plurality of packets. The packet header parser is used for recognizing the type of service field in each packet and for generating a minimum delay control signal. The second calculating device is used for determining a coalescing interrupt number signal according to the packet information and the minimum delay control signal. The interrupt controller is used for transmitting an interrupt control signal to process the packet according to the coalescing interrupt number signal. The system of the invention can process the minimum delay packet in a minimum delay time so as to reduce the delay time of the minimum delay packet and the average delay time of the packets and to avoid the miss owing to the delay of the packet.

The present invention discloses a multi-priority media access control method for a multi-channel slotted ring network. In the slotted ring networks, each node has one tunable transmitter and one fixed receiver for data channels, and is able to inspect slot status on all channels. The header slot format defines the slot priorities on ring networks and limits which packets can be transmitted through the slots. By assigning slot priority based on two thresholds to raise and lower slot priority, multiple priority packets can be transmitted.
