Technical Notes and Briefs: NTP Server Capacity Testing Large-scale NTP deployments require consideration for the network’s time synchronization architecture. Network time deployments are usually driven by considerations for reliability, scalability, manageability and security. The capability of modern NTP servers, such as Spectracom SecureSync® and NetClock® time servers, is such that capacity does not impact the design of the synchronization architecture.  pdf - 202 KB

Technical Notes and Briefs: Differences Between NTP and SNTP NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are very similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e. full implementation NTP) is being used, or if SNTP is being used. pdf - 64 KB
