NoviAccelerator by NoviFlow is a solution designed for multi-terabit volumetric DDoS attack mitigation in CSP networks. It combines multi-Tbps switch-based mitigation and congestion control with an Intrusion Detection System (IDS) to economically detect and mitigate volumetric DDoS and TCP state exhaustion attacks. NoviAccelerator provides protection against DDoS attacks at reduced costs by offloading the mitigation function to the forwarding plane, freeing up the processing capacity of the IDS. It supports both BITW and hairpin deployments, offers congestion control and load balancing in the switch fabric, and detects and mitigates common large volumetric DDoS attacks. NoviAccelerator minimizes false positives, enhancing threat detection accuracy, and reduces DDoS mitigation response time from minutes to seconds. It leverages open-source software and disaggregated COTS hardware to deliver Tbps performance and over 60 percent reduction of TCO compared to other volumetric solutions.
