Network Hub Pre-Allocating Bandwidth for VoIP Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network environments like VSAT or TDMA, network hubs face challenges in efficiently allocating bandwidth between active and idle remote terminals, particularly when they share similar Quality of Service (QoS) levels, leading to difficulties in reducing latency, jitter, and packet loss in VoIP communications.
Innovation Solution
Implementing a system where the network hub pre-allocates bandwidth to active remote terminals based on expected VoIP communication needs, using separate network resources for different communications to improve efficiency and reduce latency, jitter, and packet loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network hub allocates bandwidth based on QoS levels for all remote terminals, then bandwidth allocation is simplified, but active and idle terminals with similar QoS levels cannot be differentiated, leading to inefficient resource allocation
Solution Approach 1:
The network hub performs preliminary identification of terminal states (active vs. idle) before bandwidth allocation occurs. By determining terminal activity status in advance of the allocation decision, the system can differentiate between active and idle terminals even when they have similar QoS levels, enabling more efficient bandwidth distribution without requiring complex real-time analysis during the allocation process
2Reliability
If the network hub uses real-time resource allocation for VoIP communications, then resource utilization is optimized, but latency, jitter, and packet loss increase due to allocation delays
Solution Approach 1:
The network hub pre-allocates bandwidth resources to active remote terminals before VoIP communications begin. By performing the allocation action in advance rather than in real-time during communication, the system eliminates allocation delays that would otherwise cause latency, jitter, and packet loss, while still maintaining efficient resource utilization through activity-based identification
Solution Approach 2:
The patent segments network resources by creating dedicated bandwidth allocations for different active terminals rather than using a shared pool. This segmentation allows each active terminal to have guaranteed bandwidth resources, eliminating the contention and delays that occur when multiple terminals compete for shared resources in real-time
3Productivity
If the network hub shares network resources among all remote terminals, then resource utilization is maximized, but active terminals experience performance degradation due to interference from idle terminals
Solution Approach 1:
The network hub performs preliminary identification of which terminals are actively communicating before allocating bandwidth. This advance identification allows the hub to allocate bandwidth only to active terminals, excluding idle terminals from resource consumption, thereby maintaining high resource utilization while preventing idle terminals from degrading the performance of active communications
Solution Approach 2:
The patent applies different resource allocation qualities to different terminals based on their activity state. Active terminals receive dedicated, prioritized bandwidth allocations with guaranteed performance, while idle terminals receive no allocation. This local differentiation in resource quality ensures that active communications receive the necessary performance guarantees without sacrificing overall resource utilization efficiency

AI summary
A first device may pre-allocate network resources for multiple communications between a first device and a second device. The second device may be associated with one or more third devices. The network resources may be pre-allocated prior to the second device receiving a request for a communication, of the multiple communications, for transmission from a third device of the one or more third devices. The first device may receive an indication to allocate the network resources for the communication. The first device may allocate a portion of the network resources for the communication. The first device may cause the communication to be transmitted between the first device and the second device and between the second device and the third device. The first device may deallocate the portion of the network resources after causing the communication to be transmitted.
