Load Distribution System for Packet Transfer Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional load distribution technologies do not consider traffic characteristics, leading to underutilization of packet transfer devices, as they fail to differentiate between traffic types that have varying packet lengths, resulting in capacity imbalances.
Innovation Solution
A load distribution system that determines the flow attribute of incoming packets as either high-bps (long packets) or high-pps (short packets) and routes them to packet transfer devices with low load states matching the attribute, using a flow monitoring unit and path table management to optimize load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traffic is evenly distributed to packet transfer devices using conventional load distribution technology, then the system maintains simple routing logic, but transfer capacity cannot be fully utilized due to ignoring traffic characteristics
Solution Approach 1:
The patent applies local quality by differentiating load distribution strategies based on traffic characteristics. Specifically, it identifies whether traffic consists of long packets (high-bps) or short packets (high-pps) and applies different routing policies: high-bps traffic is distributed to devices with available data volume capacity, while high-pps traffic is distributed to devices with available packet processing capacity. This localized adaptation to traffic type resolves the contradiction by optimizing each traffic stream according to its specific needs rather than applying uniform distribution.
Solution Approach 2:
The patent changes the parameter of load distribution from uniform allocation to characteristic-based allocation. It introduces flow attribute determination that classifies traffic into high-bps or high-pps categories, then dynamically selects destination packet transfer devices based on matching capacity characteristics. This parameter change enables full utilization of transfer capacity by aligning traffic types with appropriate device capabilities, resolving the underutilization problem while maintaining manageable complexity through automated classification.
2Reliability
If packet transfer devices are selected without considering flow attributes, then the system operates with simpler device selection logic, but capacity exhaustion occurs in specific transfer capacity dimensions
Solution Approach 1:
The patent applies preliminary action by determining flow attributes (high-bps or high-pps) before packet forwarding decisions are made. The system classifies incoming traffic into categories based on packet length characteristics and pre-determines the appropriate destination packet transfer device type. This preliminary classification ensures that capacity exhaustion is prevented by directing long packet traffic to devices with data volume capacity and short packet traffic to devices with packet processing capacity, thereby maintaining reliable and balanced capacity utilization.
Solution Approach 2:
The patent introduces flow attribute determination as an intermediary mechanism between packet reception and forwarding. This intermediary classifies traffic into high-bps or high-pps categories and uses this classification to select appropriate destination devices. The intermediary resolves the contradiction by bridging the gap between simple routing logic and reliable capacity utilization, ensuring that traffic characteristics are considered without requiring complex manual intervention.
3Productivity
If load distribution ignores traffic characteristics, then the system maintains easier monitoring and management, but transfer capacity remains underutilized due to capacity imbalances
Solution Approach 1:
The patent applies self-service by enabling packet transfer devices to automatically determine their own capacity characteristics and select appropriate destination devices based on flow attributes. The system autonomously classifies traffic into high-bps or high-pps categories and routes them to devices with matching available capacity without requiring external intervention. This self-service mechanism resolves the contradiction by achieving full capacity utilization through automated, characteristic-based routing while maintaining ease of operation through decentralized decision-making.

AI summary
A load distribution system has: determination means for determining, upon an input port receiving a packet, a flow attribute indicating whether a flow configured by the packet is a flow that tends to include many long packets or a flow that tends to include many short packets; and output means for outputting the packet to a packet transfer device in a load state indicating that a load applied by the flow of the flow attribute is low, of a plurality of packet transfer devices, in accordance with the flow attribute determined by the determination means.
