Information Processing Device Packet Life Control for Server Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The processing burden on server devices is increased due to repetitive packet transmission, especially when the port maintaining time of communication processing devices with NAT function is short, leading to inefficiencies and accessibility issues from external devices.
Innovation Solution
An information processing system that includes a transmission judging section, a life judging section, and a life setting section to determine whether to set a life for repetition packets, allowing some packets to not reach the server device, thereby reducing the processing burden by modifying the life of packets and controlling their transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are repetitively transmitted to maintain port accessibility and notify server of IP changes, then external device accessibility is improved, but server device processing burden increases
Solution Approach 1:
The patent applies partial action by having only certain network devices (those that need external accessibility) transmit repetitive packets, while other devices do not. This reduces the overall packet load on the server while maintaining necessary port accessibility for specific devices. The life setting section selectively sets packet lifetimes based on device characteristics and network conditions.
Solution Approach 2:
The patent changes the lifetime parameter of repetitive packets dynamically. The life setting section adjusts packet lifetime based on port maintaining time, network conditions, and device characteristics. By optimizing packet lifetime, the system reduces unnecessary packet transmissions while ensuring packets reach the server in time to maintain port accessibility and notify IP changes.
2Productivity
If port maintaining time is shortened to reduce packet transmission frequency, then server processing burden is reduced, but external device accessibility reliability decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and setting appropriate packet lifetimes before transmission. The life setting section determines optimal packet lifetime based on port maintaining time and network conditions, ensuring packets will reach the server in time to maintain port accessibility. This preliminary configuration reduces the need for frequent packet transmissions while guaranteeing accessibility maintenance.
Solution Approach 2:
The system uses feedback from port maintaining time requirements to adjust packet transmission strategies. The life setting section continuously monitors whether current packet lifetimes are sufficient for maintaining port accessibility and adjusts transmission parameters accordingly, balancing server load with accessibility requirements.

AI summary
An information processing device 1 includes a transmission judging section 11 for judging whether to transmit a repetition packet, a life judging section 12 for judging whether to set a life not reaching a server device 3 to the repetition packet, a life setting section 14 for setting the life of the repetition packet to the life not reaching the server device 3 when the life judging section 12 judges to set the life not reaching the server device 3, and setting the life of the repetition packet to the life reaching the server device 3 when the life judging section 12 judges to set the life reaching the server device, and a transmitting section 15 for transmitting a repetition packet having the life set by the life setting section 14, when the transmission judging section 11 judges to transmit the repetition packet. It is possible to reduce a processing burden on the server device in an information processing system provided with the information processing device for repetitively transmitting the packet and the server device for receiving the packet.
