Network Latency Management via Dynamic Routing Policies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management methods optimize throughput at the cost of increased latency, failing to efficiently manage bandwidth and latency simultaneously, which can lead to suboptimal performance as bandwidth grows beyond content services.
Innovation Solution
A latency manager entity within the communication network gathers information to determine the impact of applications on customer experience and network performance, using trace-routes and data packet fields like TTB and MJ to optimize data packet routing, prioritize transmission, and adjust routing policies dynamically to ensure timely and successful delivery.

Engineering Contradiction Analysis
1Productivity
If network management optimizes throughput to save bandwidth and network resources, then bandwidth utilization is improved, but latency increases
Solution Approach 1:
The patent implements dynamic routing policies that adjust in real-time based on network conditions, application requirements, and latency sensitivity. The system transitions from static to dynamic route selection, allowing the network to adapt throughput optimization strategies to specific application needs, thereby reducing latency for time-sensitive traffic while maintaining high throughput for other traffic types.
Solution Approach 2:
The patent applies different routing policies and quality of service parameters to different applications and data packets based on their specific requirements. Instead of uniform throughput optimization across all traffic, the system tailors routing decisions to individual application characteristics, ensuring that latency-sensitive applications receive preferential treatment while other applications benefit from throughput optimization.
2Quantity of substance
If bandwidth capacity grows beyond content services needs, then network capacity is improved, but latency management becomes insufficient
Solution Approach 1:
The patent introduces and utilizes the TTB (Time To Buffer) parameter to dynamically manage latency based on available bandwidth and application requirements. By incorporating time-based parameters into routing decisions alongside traditional bandwidth considerations, the system effectively manages latency even as bandwidth capacity grows, ensuring that excess bandwidth does not lead to degraded latency performance.
3Loss of time
If trace-route and network information gathering is implemented, then routing optimization is improved, but network device complexity increases
Solution Approach 1:
The patent introduces a latency manager as an intermediary component that handles the complexity of trace-route operations and network information gathering. Rather than requiring every network device to perform complex latency measurements and routing optimizations, the latency manager centralizes these functions, simplifying individual device complexity while achieving network-wide latency optimization.

AI summary
Systems and methods are described herein for managing information transmitted between and/or within communication networks. Aspects discussed herein relate to monitoring and characterizing data flows with network and/or latency parameters, such as a time-to-buffer (TTB) parameter. Latency managers, network components, or other suitable devices operating in a communication network may utilize TTB parameter information as a management mechanism throughout the communication network to negotiate and schedule the delivery of data packets in view of a variety of factors, e.g., network performance, application priority, and the like. Such devices may be further configured to modify network or routing policies based on network performance and latency information obtained from and/or shared by various network components and devices in the communication network.
