Multi-domain Scheduling for Subordinate Networking Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-domain point-to-multipoint networks, scheduling and dynamic bandwidth allocation become complex and lead to latency and jitter when multiple subordinate networks are associated with a primary network, particularly due to conflicts and collisions in signaling across multiple paths.
Innovation Solution
Implementing a multi-domain scheduler with pass-through reporting capabilities, where aggregating devices like FCUs relay scheduling requests to a central terminal, reducing processing delays and allowing staggered or overlapping data transmissions to minimize latency and jitter.

Engineering Contradiction Analysis
1Quantity of substance
If multiple subordinate P2MP networks are associated with a primary P2MP network to increase network capacity and coverage, then the network can serve more secondary units, but the scheduling complexity and bandwidth allocation difficulty increase significantly
Solution Approach 1:
The patent divides the multi-domain P2MP network into hierarchical segments with domain-specific schedulers at each level (subordinate networks) and a root scheduler at the primary network level. Each scheduler manages only its local domain, breaking down the overall complex scheduling problem into smaller, manageable segments that can be handled independently while maintaining coordination through standardized interfaces.
2Reliability
If traditional scheduling methods are used in multi-domain P2MP networks, then existing scheduling algorithms can be applied, but latency and jitter increase due to conflicts and collisions in signaling across multiple paths
Solution Approach 1:
The patent implements preliminary scheduling actions where the root scheduler pre-coordinates transmission opportunities with subordinate schedulers before actual data transmission occurs. This advance planning allows subordinate networks to prepare their signaling in advance, avoiding last-minute conflicts and collisions that cause latency and jitter, while ensuring reliable signaling delivery.
Solution Approach 2:
The root scheduler acts as an intermediary that mediates between multiple subordinate P2MP networks and the primary network. It coordinates scheduling decisions across domain boundaries, resolving potential conflicts before they manifest as signaling collisions, thereby reducing latency and jitter while maintaining signaling reliability across the multi-domain architecture.
3Productivity
If dynamic bandwidth allocation is implemented across multiple subordinate networks, then bandwidth can be optimized for each network, but the coordination overhead and processing delays increase
Solution Approach 1:
The patent segments bandwidth allocation authority by implementing domain-specific schedulers at each subordinate network level that independently perform dynamic bandwidth allocation for their local networks. This segmentation allows each domain to optimize bandwidth efficiently without waiting for centralized coordination, reducing processing delays while maintaining overall network optimization through hierarchical coordination.

AI summary
Multi-domain scheduling for subordinate networking is contemplated. The scheduling may include controlling a terminal to facilitate interfacing an Internet Protocol (IP) network with a point-to-multipoint (P2MP) network where the P2MP network includes one or more aggregating devices to facilitate interfacing signaling with devices/units associated with one or more subordinate P2MP networks.
