Summary Current NTP is mature, ubiquitous and extensible Extensions can be backward compatible with existing NTP eNTP & NTP Clients can be mixed in deployment Existing NTP would benefit from reliability SW based eNTP could see some performance enhancements Stratum 1 performance is viable over managed IP networks utilizing high quality stratum oscillators (distributed S1 NTP via SSUs) Sub-Microsecond performance is achievable using VCXO and OCXO Clients (also meets G.823/G.824) |
