Point-to-Multipoint Transmission Time Allocation for Messaging Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network management techniques in point-to-multipoint networks, such as passive optical networks, become inefficient as the number of downstream devices increases, leading to wasteful use of bandwidth and processing resources due to inefficient messaging procedures.
Innovation Solution
A network device determines and allocates time allocations for each source based on information rates, such as committed and excess information rates, to manage data transmissions efficiently, ensuring that processing and transmission times are optimized within a time cycle.

Engineering Contradiction Analysis
1Productivity
If traditional messaging procedures are used to coordinate data transmissions in point-to-multipoint networks, then network management can be implemented, but bandwidth and processing resources are wasted as the number of downstream devices increases
Solution Approach 1:
The patent implements periodic time cycles with predetermined time allocations for different downstream devices. Instead of continuous messaging procedures, the system uses periodic time slots where each device is granted transmission permission during its allocated time window, eliminating the need for constant coordination messages and reducing bandwidth and processing resource consumption.
Solution Approach 2:
The patent segments the communication medium access by dividing time into discrete allocations for different downstream devices. Each device receives dedicated time slots within time cycles, separating their transmission opportunities and eliminating the need for competitive access and coordination messaging, thereby improving network management efficiency while reducing resource waste.
2Adaptability or versatility
If the number of downstream devices sharing the communication medium increases, then network capacity is enhanced, but messaging procedures become inefficient
Solution Approach 1:
The patent creates a universal time allocation framework that can accommodate any number of downstream devices by dynamically adjusting time slot assignments within each time cycle. The predetermined time allocations are configured based on each device's information rates and service requirements, allowing the system to scale to support increasing network capacity without degrading messaging procedure efficiency.
Data Source
AI summary
Methods and systems for managing data transmissions are disclosed. An example method can comprise determining a plurality of time allocations for a time cycle. The plurality of time allocations can comprise a first time allocation which can be determined based on an information rate, a committed information rate, an excess information rate, an effective bandwidth rate, other factors, or a combination thereof. Data can be received from multiple sources into a buffer, for example, and can be processed within a time cycle if processing the data will not exceed the time allocation.
