Microsemi has published a new application note on its Security Hardened SyncServer NTP Reflector.

The NTP (Network Time Protocol) Reflector is a fast, accurate NTP server. It features denial of service resilience, monitoring and notification functions.

Characteristics include 100 percent hardware NTP time-stamping for accuracy and high performance; NTP packet monitoring for DoS detection; bandwidth limiting and packet filtering for CPU protection; and alarming if NTP loading is above expected levels.

To help users better understand the advantages of Microsemi’s NTP Reflector and packet limiting/monitoring technology, the company explains the underlying technology and its security benefits in the new application note, available for download.

Key Characteristics

  • 100 percent hardware NTP timestamping for accuracy and high performance
  • NTP Packet monitoring for DoS detection
  • Bandwidth limiting and packet filtering for CPU protection
  • Alarming if NTP loading is above expected levels.

The NTP Reflector is one of the many differentiating features of Microsemi’s new SyncServer S600 series network time servers.

The reflector is a real-time, hardware-based NTP packet identification and time-stamping engine uniquely designed to protect the SyncServer CPU from excessive network traffic denial of service  attacks and notify the operator if NTP traffic is above expected levels.

The innovative technology enables extremely high-bandwidth, high-accuracy, high-reliability and security-hardened NTP operations.
