The next generation of eBypass, sometimes called "Smart Bypass" or "Adaptive Bypass," uses machine learning. Instead of reacting to a crash, predictive eBypass analyzes telemetry:
Vendors are also integrating eBypass directly into Smart NICs (Network Interface Cards), placing the bypass logic on the same silicon as packet processing. This shrinks failover time to under 1 microsecond—effectively invisible to TCP sessions. ebypass
Many confuse eBypass with physical network taps or simple A/B switches. Here is the distinction: The next generation of eBypass, sometimes called "Smart
| Feature | Traditional Mechanical Bypass | eBypass (Electronic) | | :--- | :--- | :--- | | Switching Speed | 50–150 milliseconds (mechanical bounce) | 3–15 milliseconds (solid state) | | Moving Parts | Yes (relays) | No (semiconductor) | | Power Required for Bypass | Usually fails open without power | Can be configured for fail-open or fail-close | | Monitoring | Basic link detection | Deep packet heartbeat, latency thresholds | | Use Case | Legacy copper networks | High-frequency trading, 5G backhaul | Vendors are also integrating eBypass directly into Smart
Industrial environments (power grids, water treatment plants) cannot tolerate network downtime. However, they require inline security inspection. eBypass allows safety systems to remain active even when security appliances are being serviced.
Data traffic flows from the network switch into the eBypass device, then into the security appliance (firewall/IPS), and back out to the network. The eBypass device monitors the appliance’s link status and heartbeat signals.
