Common Processing Units for Packet Transfer Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packet transfer processing devices consume power for dedicated inbound and outbound processing units even when traffic volume is low, resulting in inefficient power usage.
Innovation Solution
A method and device that utilize common processing units for both inbound and outbound processing, with power switching to reduce consumption by shutting off unused units during low traffic volumes, and individual processing units for non-sharable tasks, allowing adaptive control of power supply based on traffic volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated inbound processing unit and dedicated outbound processing unit are operated always, then packet transfer processing functionality is ensured, but power consumption increases even when traffic volume is low
Solution Approach 1:
The patent applies universality by introducing common processing units that can perform both inbound processing and outbound processing functions. Instead of having dedicated units for each direction, the common processing units are shared resources that handle packet processing for both inbound and outbound traffic, allowing the system to reduce the number of active processing units when traffic volume is low while maintaining full functionality when needed
Solution Approach 2:
The patent implements dynamics by making the processing unit configuration adaptable to traffic conditions. The system dynamically selects and activates only the necessary number of common processing units based on current traffic volume, transitioning between different operational states (full operation, partial operation, standby) to match actual processing demands, thereby reducing power consumption during low-traffic periods
2Use of energy by moving object
If common processing units are used for both inbound and outbound processing, then power consumption is reduced, but processing capacity may be insufficient during high traffic volume
Solution Approach 1:
The system dynamically adjusts the number of active common processing units based on traffic volume thresholds. When traffic exceeds a predetermined threshold, additional common processing units are activated to increase processing capacity. This dynamic scaling ensures that processing capacity matches actual demand, preventing both under-provisioning during high traffic and over-provisioning during low traffic
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple common processing units in standby state and establishing predetermined traffic volume thresholds. When traffic approaches these thresholds, the system proactively activates additional processing units before capacity is exceeded, ensuring smooth handling of traffic surges without performance degradation
3Productivity
If dedicated processing units are used for inbound and outbound processing, then processing performance is ensured, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by replacing dedicated inbound and outbound processing units with shared common processing units. These common processing units perform both inbound and outbound processing functions, reducing the total number of processing units required in the system while maintaining equivalent processing performance through resource sharing
Solution Approach 2:
The patent applies merging by combining the previously separate inbound and outbound processing functions into a unified common processing unit architecture. Instead of maintaining distinct dedicated units for each direction, the system merges these functions into shared resources that handle both types of processing, thereby simplifying the overall device structure

AI summary
A packet transfer processing device includes common processing units that perform processing common to inbound processing of a packet received from an access network for transfer to a core network and outbound processing of a packet received from the core network for transfer to the access network, an input destination switching unit that selects common processing units to which the received packets are to be input, an output destination switching unit that outputs packets processed by the common processing units to a destination network, an individual processing switching unit that selects a common processing unit to connect to an individual processing unit that performs individual processing not performed by the common processing units as part of inbound processing, and a control unit that controls the input destination switching unit, the individual processing switching unit, and switching supply/shutoff of power to the common processing units.
