Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If token bucket algorithms (single rate three color marker or two rate three color marker) are used for traffic policing, then packet traffic can be controlled and marked with colors, but the method can only work based on one path and cannot cover user traffic in multipath transmission scenarios
Solution Approach 1:
The patent segments the traffic policing function by introducing a separate concentration device that collects statistical information from multiple paths, and a path selection device that independently determines forwarding paths. This segmentation allows the policing system to handle multipath traffic without increasing the complexity of individual policing components, as each component remains simple while the overall system achieves versatile multi-path coverage.
Solution Approach 2:
The patent introduces a concentration device as an intermediary that collects statistical information from multiple transmission paths and sends it to a path selection device. This intermediary mechanism enables the system to aggregate information from multiple paths without requiring each individual path to have complex policing capabilities, thus achieving versatile traffic policing coverage while maintaining component simplicity.
2Reliability
If multipath transmission is implemented for load balancing and redundancy, then network reliability and bandwidth utilization improve, but existing traffic policing methods cannot effectively police user traffic across multiple paths
Solution Approach 1:
The patent segments the network function into a concentration device that handles statistical information collection from multiple paths, and a path selection device that handles forwarding path determination. This segmentation allows the system to maintain multipath transmission for reliability while adding traffic policing capability through the coordinated action of segmented components, each performing a specific function without interfering with the other.
Solution Approach 2:
The patent creates a universal traffic control system where the concentration device and path selection device work together to handle both multipath transmission and traffic policing functions. The path selection device receives statistical information from the concentration device and makes forwarding path decisions that incorporate policing considerations, enabling a single system to serve multiple functions including reliability, load balancing, and traffic control.
3Measurement precision
If statistical information is collected from multiple paths to enable effective traffic policing, then traffic control accuracy improves, but system complexity and processing overhead increase
Solution Approach 1:
The patent introduces a concentration device as an intermediary that collects statistical information from multiple paths and sends it to a path selection device. This intermediary approach centralizes the complex statistical collection function in a dedicated device, allowing the path selection device to receive pre-processed information and make forwarding decisions without needing to directly manage complex multi-path statistics, thus improving measurement accuracy while controlling system complexity.
Solution Approach 2:
The patent extracts the statistical information collection function from the path selection process and places it in a separate concentration device. By taking out the complex statistical aggregation task into a dedicated component, the system achieves accurate traffic measurement across multiple paths while keeping the path selection logic simpler and more manageable.
