CMTS Bonding for Legacy and New Transmission Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently managing the bonding of transmissions between legacy and new transmission systems, particularly in determining optimal routing and scheduling to alleviate congestion and ensure seamless data transfer across different transmission modes.
Innovation Solution
A method is disclosed that involves monitoring the output of legacy Cable Modem Termination Systems (CMTS) to determine whether to route data through legacy or new CMTS, and creating a new transmission schedule based on captured legacy schedules to manage network congestion, allowing for backward compatibility and efficient data transfer between legacy and new receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is routed through legacy CMTS to ensure backward compatibility, then compatibility with legacy receivers is maintained, but network congestion increases and transmission efficiency decreases
Solution Approach 1:
The system dynamically switches between legacy and new CMTS based on real-time network conditions. The new CMTS monitors the output of the legacy CMTS and determines routing decisions accordingly, allowing the system to adapt its configuration dynamically rather than being fixed, thus resolving the contradiction between maintaining compatibility and ensuring transmission efficiency
Solution Approach 2:
The new CMTS acts as an intermediary between the head end and receivers, managing the bonding between legacy and new transmission systems. It captures transmission schedules from the legacy CMTS and creates new schedules that optimize data flow, serving as a mediator that maintains compatibility while improving efficiency
2Speed
If new transmission system is used to improve transmission capacity, then data transfer speed increases, but network congestion occurs during peak usage periods
Solution Approach 1:
The new CMTS captures transmission schedules from the legacy CMTS in advance and creates new transmission schedules before peak congestion occurs. By planning and scheduling data transmissions ahead of time, the system prevents congestion rather than reacting to it, maintaining reliability while utilizing high-speed transmission capabilities
Solution Approach 2:
The new CMTS continuously monitors the output of the legacy CMTS and uses this feedback to determine routing decisions and create optimized transmission schedules. This feedback mechanism allows the system to adjust to changing network conditions and prevent congestion by adapting transmission patterns based on real-time performance data
3Quantity of substance
If bonding between legacy and new CMTS is implemented to increase bandwidth, then data transmission capacity increases, but routing complexity increases
Solution Approach 1:
The new CMTS is designed to perform multiple functions: it serves as both a standalone transmission system and as a bonding partner with the legacy CMTS. By capturing and creating transmission schedules, it manages the complexity of bonding operations, allowing the system to increase capacity without proportionally increasing routing complexity
Solution Approach 2:
The new CMTS captures transmission schedules from the legacy CMTS and creates new schedules based on these captured patterns. This copying approach allows the system to inherit the organizational structure of the legacy system while optimizing it, thereby increasing capacity without creating entirely new routing complexities
