1588 PTP
The 1588 PTP supports the following Master/Client communication;
however
Unicast
is used for the Telocom Profile.
Multicast
: A Master clock sends its Sync/Follow Up and Delay
Response in a multicast mode. A Client can collect information from
many Master clocks and select the Master clock that is best suited for
its application.
Unicast
: A dedicated communication link is established between the
Master and the Client clock. This mode of operation requires a
negotiation which is initiated by the Client clock.
The 1588 PTP messages can be mapped on the following protocols;
however UDP IPv4 is used for the Telecom Profile.
UDP/IPv4
UDP/IPv6
Ethernet
1588 PTP Profiles
The purpose of a PTP profile is to allow organizations to specify particular
selections of attribute values and optional features of PTP that, when using
the same transport protocol, inter-work and achieve a performance that
meets the requirements of a given application. The following describes the
Telecom Profile.
The Telecom Profile G.8265.1 is designed for frequency synchronization in
Telecom network applications. The main attributes of this profile are:
Unicast communication with the Grand Master
UDP/IPv4 network layer
With the Telecom Profile, the Client Clock initiates the communication to
the Master Clock by making a request for service that consists of sending
Signaling messages containing a REQUEST UNICAST TRANSMISSION TLV
to the IP address of the Master Clock.
