From the “Scope” section of the standard: “This
standard defines a protocol enabling precise synchronization of clocks in
measurement and control systems implemented with technologies such as network
communication, local computing and distributed objects. The protocol will be
applicable to systems communicating by local area networks supporting multicast
messaging including but not limited to Ethernet. The protocol will enable
heterogeneous systems that include clocks of various inherent precision, resolution and stability to synchronize. The protocol will
support system-wide synchronization accuracy in the sub-microsecond range with
minimal network and local clock computing resources. The default behavior of
the protocol will allow simple systems to be installed and operated without
requiring the administrative attention of users.” It is intended to address
time synchronization requirements not met by other technologies such as the
Network Time Protocol (NTP) or Simple Network Time Protocol (SNTP). It defines
an architecture of time servers and time gateways, some of which may be
embedded in networking devices such as switches and routers. Published as IEEE
1588-2002.
