Implementing data compression techniques for inter-node communication is the most effective strategy to reduce latency and stabilize frame processing times in a distributed real-time videoprocessing application.
When network bandwidth between nodes is a bottleneck, compressing the data (e.g., frames or intermediate model outputs) before transmission reduces the volume of data transferred, alleviating network congestion and improving latency. NVIDIA's documentation, such as the "DeepStream SDK Reference" and "AI Infrastructure for Enterprise," highlights the importance of optimizing inter-node communication for distributed GPU systems, including compression as a viable technique.
Increasing GPUs per node (A) may improve local processing but does not address inter-node bandwidth issues. Reducing video resolution (B) lowers data load but sacrifices quality, which may not be acceptable.
Optimizing models for lower complexity (C) reduces compute load but does not directly solve network bottlenecks. NVIDIA's guidance on distributed systems emphasizes communication optimization, making compression the best solution here.
