Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional congestion monitoring methods are used, then network monitoring is performed, but measurement accuracy is insufficient for millisecond-level traffic adjustment requirements
Solution Approach 1:
The patent applies preliminary action by pre-configuring delimitation packets with timestamp information and interval parameters before congestion measurement begins. These packets are sent in advance to establish measurement boundaries, enabling the system to capture congestion status at precise millisecond intervals without delay when congestion occurs
Solution Approach 2:
The patent replaces conventional mechanical timing and measurement systems with a packet-based temporal marking system. Delimitation packets carry timestamp information that substitutes for traditional hardware timers, allowing software-based precise time measurement and congestion interval calculation without relying on mechanical timing components
2Measurement precision
If delimitation packets with timestamps are used, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The delimitation packets serve multiple functions simultaneously: they mark measurement intervals, carry timestamp information for time synchronization, identify congestion status, and provide reference points for statistics collection. This multi-functionality reduces the need for separate signaling mechanisms, thereby limiting the increase in device complexity while achieving high measurement precision
Solution Approach 2:
The patent changes the parameter representation by encoding timestamp information and interval parameters directly within the packet structure rather than using separate control signals. This parameter integration simplifies the overall system architecture while maintaining high measurement precision, as all necessary measurement data is contained within the standard packet format

AI summary
This application provides a congestion measurement method. The method includes: receiving a first delimitation packet, where the first delimitation packet includes a first identifier, and the first identifier is used to indicate a moment at which the second network node sends the first delimitation packet; collecting, based on the first delimitation packet, statistics about a congestion status of the first network node by using a first time interval as a periodicity, where the first time interval is a time interval at which the second network node sends two neighboring delimitation packets; and sending a first-type statistics packet to the second network node by using the first time interval as a periodicity.
