Global Policing Network Bandwidth Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic policing systems operate locally on network elements without considering global network traffic, leading to inefficiencies in bandwidth management and increased complexity when attempting to implement global policing.
Innovation Solution
A system that includes a network device with a local policer and a communications module to send and receive state information with a remote global policer, allowing for global bandwidth policing across multiple network devices, maintaining policing quotas and adjusting based on aggregated network traffic data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local policing is implemented on each network element, then bandwidth control is enforced locally, but global bandwidth management capability deteriorates
Solution Approach 1:
The policing function is segmented into local policers on individual network elements and a global policer that coordinates them. Each local policer handles enforcement locally while the global policer maintains overall bandwidth management across the network, resolving the contradiction between local control and global management capability
Solution Approach 2:
A global policer acts as an intermediary between multiple local policers, collecting state information from them and coordinating their actions to achieve global bandwidth management. This intermediary enables global perspective while maintaining local enforcement capabilities
2Adaptability or versatility
If global policing is implemented across multiple network devices, then global bandwidth management is achieved, but system complexity increases
Solution Approach 1:
The complex global policing function is segmented into simpler local policer components that can be independently implemented on each network element. This segmentation reduces the complexity burden on individual devices while achieving global management through coordination
Solution Approach 2:
Local policers provide state information feedback to the global policer, which then coordinates their actions. This feedback mechanism enables global bandwidth management through relatively simple local components, reducing overall system complexity
