Open-Loop Bandwidth Allocation for Satellite Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bandwidth allocation techniques in communication systems consume network capacity as overhead due to closed-loop feedback mechanisms, which is inefficient and costly.
Innovation Solution
An open-loop bandwidth allocation scheme that detects traffic type and reserves bandwidth based on predetermined service plans without feedback to the terminal, using a processor and memory to manage bandwidth allocation patterns across communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If closed-loop feedback mechanisms are used for bandwidth allocation, then bandwidth allocation accuracy is improved, but network capacity consumption increases due to overhead
Solution Approach 1:
The patent extracts and removes the feedback mechanism from the bandwidth allocation system, transitioning from closed-loop to open-loop allocation. This eliminates the overhead associated with feedback messages while maintaining allocation functionality through predetermined patterns stored in terminals.
Solution Approach 2:
The system performs preliminary action by pre-configuring bandwidth allocation patterns in terminals before actual bandwidth allocation is needed. These patterns are established based on service plans and traffic types, allowing terminals to autonomously allocate bandwidth without real-time feedback.
2Adaptability or versatility
If closed-loop feedback mechanisms are used for bandwidth allocation, then bandwidth allocation adaptability is improved, but device complexity increases
Solution Approach 1:
The terminal performs self-service by autonomously allocating bandwidth based on predetermined patterns stored locally. The terminal detects its own traffic type and selects appropriate allocation patterns without requiring external feedback or control messages, thereby reducing system complexity.
Solution Approach 2:
Adaptability is achieved through preliminary configuration of multiple bandwidth allocation patterns corresponding to different service plans and traffic types. The terminal is pre-loaded with these patterns and can autonomously select the appropriate one based on current traffic conditions, eliminating the need for complex real-time negotiation.
3Loss of energy
If open-loop bandwidth allocation is used, then overhead is reduced, but bandwidth allocation flexibility decreases
Solution Approach 1:
The system introduces dynamics by allowing terminals to detect their own traffic type and dynamically select from multiple predetermined bandwidth allocation patterns. This enables flexibility within the open-loop framework, as the allocation adapts to traffic conditions without requiring feedback mechanisms.
Solution Approach 2:
Flexibility is achieved through parameter changes in the predetermined patterns themselves. Different service plans and traffic types are associated with different bandwidth allocation patterns (parameters), and the terminal selects the appropriate pattern based on its current needs, maintaining flexibility without feedback overhead.
Data Source
AI summary
An approach for allocating bandwidth is disclosed. A request is detected from a terminal for capacity on a communication channel based on type of traffic transmitted from the terminal. A bandwidth allocation pattern designated for the terminal is retrieved, wherein the bandwidth allocation pattern is set based on a predetermined service plan associated with the terminal. Bandwidth over the communication channel is reserved for the terminal according to the bandwidth allocation pattern without feedback to the terminal. This arrangement has particular applicability to a satellite network that provides data communication services.
