The S600 has four dedicated and isolated GbE Ethernet ports, each equipped with NTP hardware time stamping. These are connected to a very high-speed microprocessor with microsecond accurate time stamps to assure high-bandwidth NTP performance. This more than meets the need of servicing 10,000 NTP requests per second.
All of the expected network management protocols are standard in the S600. These include mandatory password access, HTTPS/SSL only (using the high encryption cipher suite), SSH, access control lists, service termination, SNMPv2/v3 and NTP MD5 authentication. All traffic to S600 is bandwidth-limited for protection against the DoS attacks.
