Dynamic Network Packet Batching for Latency and Jitter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packet processing systems face challenges in optimizing throughput performance while minimizing latency and jitter, as increasing batch size improves throughput but worsens latency, and decreasing batch size degrades throughput.
Innovation Solution
A network device dynamically adjusts batch sizes based on queue conditions and throughput performance across multiple processing stages using an additive decrease and multiplicative increase algorithm to balance latency and throughput.

1Productivity
If batch size is increased to improve throughput performance, then throughput is improved, but latency and jitter performance deteriorate
Solution Approach 1:
The patent applies dynamics by making the batch size adjustable rather than fixed. The system dynamically changes batch size parameters based on real-time network conditions, traffic patterns, and performance metrics to optimize the trade-off between throughput and latency. This allows the system to adapt batch size to different operational scenarios, improving throughput when conditions permit while reducing latency when needed.
Solution Approach 2:
The patent implements parameter changes by modifying batch size as a controllable parameter. The system adjusts this parameter based on performance feedback, traffic characteristics, and network conditions. By treating batch size as a tunable parameter rather than a static configuration, the system can optimize throughput while managing latency through parameter adjustment.
2Productivity
If batch size is increased to improve throughput performance, then throughput is improved, but jitter performance deteriorates
Solution Approach 1:
The system uses dynamics to adapt batch size in response to varying network conditions and traffic patterns. By making batch size adjustable rather than fixed, the system can respond to changes in traffic characteristics, preventing excessive jitter while maintaining throughput. The dynamic adjustment allows the system to smooth out performance variations.
Solution Approach 2:
The patent applies feedback by monitoring performance metrics including jitter and using this information to adjust batch size. The system observes the impact of current batch size settings on jitter performance and modifies parameters accordingly. This closed-loop approach allows the system to maintain stable jitter characteristics while optimizing throughput.
3Loss of time
If batch size is decreased to reduce latency, then latency is reduced, but throughput performance deteriorates
Solution Approach 1:
The system applies dynamics by making batch size adjustable based on real-time conditions. Rather than using a fixed small batch size that would limit throughput, the system dynamically determines optimal batch size, allowing it to reduce latency when necessary while maintaining throughput when conditions permit.
Solution Approach 2:
The patent implements parameter changes by treating batch size as a controllable variable. The system adjusts this parameter based on performance requirements, traffic patterns, and network conditions, allowing optimization of latency without permanently sacrificing throughput capability.
4Loss of time
If batch size is decreased to reduce latency, then latency is reduced, but throughput performance deteriorates
Solution Approach 1:
The system uses dynamics to adapt batch size to different operational requirements. By making batch size adjustable rather than fixed at a small value, the system can reduce latency when needed while preserving throughput performance when conditions allow for larger batches.

AI summary
Technologies for dynamically managing a batch size of packets include a network device. The network device is to receive, into a queue, packets from a remote node to be processed by the network device, determine a throughput provided by the network device while the packets are processed, determine whether the determined throughput satisfies a predefined condition, and adjust a batch size of packets in response to a determination that the determined throughput satisfies a predefined condition. The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.
