Abstract

Lightfleet Corporation commissioned Tolly to benchmark the multicast end-to-end average latency, skew across receiving stations, and jitter for a given station for its Lightfleet Data Distribution System (DDS). This was compared to the performance of a traditional switch as represented by the Arista Networks 7150 in conjunction with Solarflare 7122 network interface cards (NIC) and related software for the end station. Traditional LAN switch architectures add control plane and network protocol stack overhead that negatively impact performance and consistency. The Lightfleet switch-free solution delivered significantly better multicast performance with near zero skew and jitter compared to the Arista/ Solarflare solution.

Applications requiring near instantaneous packet transfer with fairness across all receivers and effectively no jitter could benefit from the Lightfleet end-to-end solution.
