- 10. Final Thoughts Be clear about test requirements • Single switch – lowest latency • Multi-chassis – highest scalability Ultra-low latency switches require ultra-low latency test equipment • Application-space tests introduce artifacts • Industry validation through recognized, trusted partners - Spirent Speed-of-light benchmarks • Secondary effects can significantly effect performance • Congestion, Load-balancing, Multi-chassis control plane To hear how we address these issues visit our booth #434 or http://www.gnodal.com
