Engineering Contradiction Analysis
1Productivity
If packets are distributed to queues based on packet types or delivery information, then packet transmission control is improved, but delay jitter cannot be controlled
Solution Approach 1:
The patent segments packets into multiple queues based on their delay jitter requirements. Each queue is assigned a specific delay jitter value, allowing packets to be classified and transmitted according to their individual delay characteristics. This segmentation enables fine-grained control over delay jitter while maintaining efficient packet transmission.
Solution Approach 2:
The patent applies local quality by assigning different delay jitter characteristics to different queues. Each queue has its own specific delay jitter parameter, allowing packets to receive customized delay treatment based on their requirements. This ensures that packets with different delay needs are handled differently, improving overall delay jitter control.
2Productivity
If multiple queues are used for packet distribution, then transmission control is enhanced, but system complexity increases
Solution Approach 1:
The patent uses parameter changes by assigning different delay jitter values to different queues. Instead of managing complex routing logic, the system simplifies queue management by using delay jitter as the key classification parameter. Packets are routed to queues based on their delay jitter requirements, making the system easier to manage while enhancing transmission control.

AI summary
In order to make it possible to control a delay jitter in packet transmission control, a packet control system (1) includes: an acquisition unit (11) that acquires a packet associated with a delay jitter which is requested; an enqueue unit (12) that enqueues the packet into a queue at a level which corresponds to the delay jitter associated with the packet among a plurality of queues which are classified into levels such that delay jitters are different for the respective levels; and a dequeue unit (13) that dequeues, in accordance with a dequeue timing specified for the queue, the packet which has been enqueued into the queue at the level corresponding to the delay jitter associated with the packet, and that sends the packet which has been dequeued to a network.
