PTP was originally defined in the '''IEEE 1588-2002''' standard, officially entitled ''"Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems"'' and published in 2002. In 2008 a revised standard, '''IEEE 1588-2008''' was released. This new version, also known as PTP Version 2, improves accuracy, precision and robustness but is not [[backwards compatible]] with the original 2002 version.<ref name=Eidson2>{{cite web |url=http://ieee1588.nist.gov/2006%20IEEE1588%20Agenda/Eidson_1588_Version%202.pdf |title=IEEE 1588 Standard Version 2 - A Tutorial |date=2 October 2010 |author=John Eidson |archiveurl=http://www.webcitation.org/5qaJpYqCH |archivedate=18 June 2010}}</ref>

==Architecture==
The IEEE 1588 standards describe a hierarchical [[Master/slave (technology)|master-slave architecture]] for clock distribution. Under this architecture, a time distribution system consists of one or more communication media (network segments), and one or more clocks. An ''ordinary clock'' is a device with a single network connection and is either the source of (master) or destination for (slave) a synchronization reference. A ''boundary clock'' has multiple network connections and can accurately bridge [[synchronization]] from one network segment to another. A synchronization ''master'' is selected for each of the network segments in the system. The root timing reference is called the ''grandmaster''.<ref>{{cite web |title=Meanings of common terms used in IEEE 1588 |url=http://ieee1588.nist.gov/terms.htm |archiveurl=http://www.webcitation.org/5qaBMRXjA |archivedate=17 June 2010 | publisher =Nation Institute or Standards and Technologies}}</ref> The ''grandmaster'' transmits synchronization information to the clocks residing on its network segment. The ''boundary clocks'' with a presence on that segment then relay accurate time to the other segments to which they are also connected.
 
A simplified PTP system frequently consists of ''ordinary clocks'' connected to a single network. No ''boundary clocks'' are used. A ''grandmaster'' is elected and all other clocks synchronize directly to it.
 
IEEE 1588-2008 introduces a clock associated with network equipment used to convey PTP messages. The ''transparent clock'' modifies PTP messages as they pass through the device. [[Timestamps]] in the messages are corrected for time spent traversing the network equipment. This scheme improves distribution accuracy by compensating for delivery variability across the network.
 
PTP typically uses the same [[Epoch (reference date)|epoch]] as [[Unix time]] (Midnight, 1 January 1970).{{#tag:ref|The profile capability under IEEE 1588-2008 allows the use of application-specific epochs.<ref name="1588-2008">{{citation |title=IEEE 1588-2008 |publisher=[[IEEE]] |date=24 July 2008 |doi=10.1109/IEEESTD.2008.4579760}}</ref>{{rp|Annex B}}|group=note}} Whereas Unix time is based on [[Coordinated Universal Time]] (UTC) and is subject to [[leap second]]s, PTP is based on [[International Atomic Time]] (TAI) and moves forward [[Monotonic function|monotonically]]. The PTP grandmaster communicates the current offset between UTC and TAI, so that UTC can be computed from the received PTP time.
 
==Protocol details==
Synchronization and management of a PTP system is achieved through the exchange of messages across the communications medium. To this end, PTP uses the following message types.
*''Sync'', ''Delay_Req'', ''Follow_Up'' and ''Delay_Resp'' messages are used by ''ordinary'' and ''boundary'' clocks and communicate time-related information used to synchronize clocks across the network.
*''Pdelay_Req'', ''Pdelay_Resp'' and ''Pdelay_Resp_Follow_Up'' are used by ''transparent'' clocks to measure delays across the communications medium so that they can be compensated for by the system. ''Transparent'' clocks and these messages associated with them are not available in IEEE 1588-2002.
*''Announce'' messages are used by the [[#Best_master_clock_algorithm|best master clock algorithm]] in IEEE 1588-2008 to build a clock hierarchy and select the ''grandmaster''.<ref group=note>In IEEE 1588-2002, information carried by ''Announce'' messages is carried in the ''Sync'' messages. In IEEE 1588-2008, the ''Sync'' message has been optimized and this information is no longer carried here.</ref>
*''Management'' messages are used by [[network management]] to monitor, configure and maintain a PTP system.
*''Signaling'' messages are used for non-time-critical communications between clocks. Signaling messages were introduced in IEEE 1588-2008.
 
Messages are categorized as ''event'' and ''general'' messages. ''Event'' messages are time-critical in that accuracy in transmission and receipt timestamp accuracy directly affects clock distribution accuracy. ''Sync'', ''Delay_Req'', ''Pdelay_Req'' and ''Pdelay_resp'' are ''event'' messages. ''General'' messages are more conventional [[protocol data units]] in that the data in these messages is of importance to PTP, but their transmission and receipt timestamps are not. ''Announce'', ''Follow_Up'', ''Delay_Resp'', ''Pdelay_Resp_Follow_Up'', ''Management'' and ''Signaling'' messages are members of the ''general'' message class.<ref name="1588-2008"/>{{rp|Clause 6.4}}
 
===Message transport===
Originally, all PTP messages were sent using [[multicast]] messaging. IEEE 1588-2008 introduced an option for devices to negotiate unicast transmission on a port-by-port basis.<ref name="1588-2008"/>{{rp|Clause 16.1}}
 
PTP messages may use the [[Internet Protocol]] (IP) for transport. The original specification used only [[IPv4]] transports,<ref name="1588-2002">{{citation |title=IEEE 1588-2002 |doi=10.1109/IEEESTD.2002.94144 |date=8 November 2002 |publisher=[[IEEE]]}}</ref>{{rp|Annex D}} but this has been extended to [[IPv6]].<ref name="1588-2008"/>{{rp|Annex F}} Over IP, messages use the [[User Datagram Protocol]] (UDP). [[Datagram]]s are transmitted using [[IP multicast]] addressing, for which multicast group addresses are defined for [[IPv4]] and [[IPv6]] (see table).<ref name="1588-2008"/>{{rp|Annex D and E}} ''Event'' messages are sent to [[port number]] 319. ''General'' messages use port number 320. Replies to ''Management'' messages are always returned to the unicast address of the originator.

==Best master clock algorithm==
The ''best master clock'' (BMC) algorithm performs a distributed selection of the best candidate clock based on the following clock properties:
; Identifier
: A universally unique numeric identifier for the clock. This is typically constructed based on a device's [[MAC address]].
; Quality
: Both versions of IEEE 1588 attempt to quantify clock quality based on expected timing deviation, technology used to implement the clock or location in a [[Stratum (disambiguation)|stratum]] schema, although only V1 knows a data field ''stratum''. PTP V2 defines the overall quality of a clock by using the data fields clockAccuracy and clockClass.
; Priority
: An administratively assigned precedence hint used by the BMC to help select a ''grandmaster'' for the PTP domain. IEEE 1588-2002 used a single [[Boolean data type|boolean variable]] to indicate precedence. IEEE 1588-2008 features two 8-bit priority fields.
; Variance
: A clock's estimate of its stability based on observation of its performance against the PTP reference.
 
IEEE 1588-2008 uses a hierarchical selection algorithm based on the following properties, in the indicated order:<ref name="1588-2008"/>{{rp|Figure 27}}
# Priority 1
# Class
# Accuracy
# Variance
# Priority 2
# Unique identifier (tie breaker)
 
IEEE 1588-2002 uses a selection algorithm based on similar properties.
 
==Synchronization==
Through use of the BMC algorithm, PTP selects a master source of time for an IEEE 1588 domain and for each network segment in the domain.
 
Clocks determine the offset between themselves and their master.<ref name="IEC">[[International standard]] [[International Electrotechnical Commission|IEC]] 61588: Precision clock synchronization protocol for networked measurement and control systems. 2004.</ref> Let the variable <math>t</math> represent physical time. For a given slave device, the offset <math>o(t)</math> at time <math>t</math> is defined by:
 
:<math>\ o(t) = s(t) - m(t)</math>
 
where <math>s(t)</math> represents the time measured at the clock at physical time <math>t</math>, and <math>m(t)</math> represents the time measured at the master at physical time <math>t</math>.
 
The master periodically broadcasts the current time as a message to the other clocks. Under IEEE 1588-2002 broadcasts are up to once per second. Under IEEE 1588-2008, up to 10 per second are permitted.
 
[[File:IEEE1588 1.jpg|center|thumb|549px|IEEE 1588 synchronisation mechanism and delay calculation]]
 
Each broadcast begins at time <math>T1</math> with a ''Sync'' message sent by the master to all the clocks in the domain. A clock receiving this message takes note of the local time <math>T1'</math> when this message is received.
 
The master may subsequently send a multicast ''Follow_Up'' with accurate <math>T1</math> timestamp. Not all masters have ability to present an accurate timestamp in the ''Sync'' message. It is only after the transmission is complete that they are able to retrieve an accurate timestamp for the ''Sync'' transmission from their network hardware. Masters with this limitation use the ''Follow_Up'' message to convey <math>T1</math>. Masters with PTP capabilities built into their network hardware are able to present an accurate timestamp in the ''Sync'' message and do not need to send Follow_Up messages.
 
In order to accurately synchronize to their master, clocks must individually determine the network transit time of the ''Sync'' messages. The transit time is determined indirectly by measuring round-trip time from each clock to its master. The clocks initiate an exchange with their master designed to measure the transit time <math>d</math>. The exchange begins with a clock sending a ''Delay_Req'' message at time <math>T2</math> to the master. The master receives and timestamps the ''Delay_Req'' at time <math>T2'</math> and responds with a ''Delay_Resp'' message. The master includes the timestamp <math>T2'</math> in the ''Delay_Resp'' message.
 
Through these exchanges a clock learns <math>T1</math>, <math>T1'</math>, <math>T2</math> and <math>T2'</math>
 
If <math>d</math> is the transit time for the ''Sync'' message, and <math>\tilde{o}</math> is the constant offset between master and slave clocks, then
 
:<math>\ T1' - T1 = \tilde{o} + d</math> and <math>\ T2' - T2 = - \tilde{o} + d</math>
 
Combining the above two equations, we find that
 
:<math>\tilde{o} = (T1'-T1-T2'+T2)/2</math>
 
The clock now knows the offset <math>\tilde{o}</math> during this transaction and can correct itself by this amount to bring it into agreement with their master.
 
One assumption is that this exchange of messages happens over a period of time so small that this offset can safely be considered constant over that period. Another assumption is that the transit time of a message going from the master to a slave is equal to the transit time of a message going from the slave to the master. Finally, it is assumed that both the master and slave can accurately measure the time they send or receive a message. The degree to which these assumptions hold true determines the accuracy of the clock at the slave device.<ref name="1588-2008"/>{{rp|Clause 6.2}}

The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.[1]

PTP was originally defined in the IEEE 1588-2002 standard, officially entitled "Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems" and published in 2002. In 2008 a revised standard, IEEE 1588-2008 was released. This new version, also known as PTP Version 2, improves accuracy, precision and robustness but is not backwards compatible with the original 2002 version.[2]

"IEEE 1588 is designed to fill a niche not well served by either of the two dominant protocols, NTP and GPS. IEEE 1588 is designed for local systems requiring accuracies beyond those attainable using NTP. It is also designed for applications that cannot bear the cost of a GPS receiver at each node, or for which GPS signals are inaccessible."[3]

Architecture

The IEEE 1588 standards describe a hierarchical master-slave architecture for clock distribution. Under this architecture, a time distribution system consists of one or more communication media (network segments), and one or more clocks. An ordinary clock is a device with a single network connection and is either the source of (master) or destination for (slave) a synchronization reference. A boundary clock has multiple network connections and can accurately bridge synchronization from one network segment to another. A synchronization master is selected for each of the network segments in the system. The root timing reference is called the grandmaster.[4] The grandmaster transmits synchronization information to the clocks residing on its network segment. The boundary clocks with a presence on that segment then relay accurate time to the other segments to which they are also connected.

A simplified PTP system frequently consists of ordinary clocks connected to a single network. No boundary clocks are used. A grandmaster is elected and all other clocks synchronize directly to it.

IEEE 1588-2008 introduces a clock associated with network equipment used to convey PTP messages. The transparent clock modifies PTP messages as they pass through the device. Timestamps in the messages are corrected for time spent traversing the network equipment. This scheme improves distribution accuracy by compensating for delivery variability across the network.

PTP typically uses the same epoch as Unix time (Midnight, 1 January 1970).[note 1] Whereas Unix time is based on Coordinated Universal Time (UTC) and is subject to leap seconds, PTP is based on International Atomic Time (TAI) and moves forward monotonically. The PTP grandmaster communicates the current offset between UTC and TAI, so that UTC can be computed from the received PTP time.

Synchronization and management of a PTP system is achieved through the exchange of messages across the communications medium. To this end, PTP uses the following message types.

  • Sync, Delay_Req, Follow_Up and Delay_Resp messages are used by ordinary and boundary clocks and communicate time-related information used to synchronize clocks across the network.
  • Pdelay_Req, Pdelay_Resp and Pdelay_Resp_Follow_Up are used by transparent clocks to measure delays across the communications medium so that they can be compensated for by the system. Transparent clocks and these messages associated with them are not available in IEEE 1588-2002.
  • Announce messages are used by the best master clock algorithm in IEEE 1588-2008 to build a clock hierarchy and select the grandmaster.[note 2]
  • Management messages are used by network management to monitor, configure and maintain a PTP system.
  • Signaling messages are used for non-time-critical communications between clocks. Signaling messages were introduced in IEEE 1588-2008.

Messages are categorized as event and general messages. Event messages are time-critical in that accuracy in transmission and receipt timestamp accuracy directly affects clock distribution accuracy. Sync, Delay_Req, Pdelay_Req and Pdelay_resp are event messages. General messages are more conventional protocol data units in that the data in these messages is of importance to PTP, but their transmission and receipt timestamps are not. Announce, Follow_Up, Delay_Resp, Pdelay_Resp_Follow_Up, Management and Signaling messages are members of the general message class.[5]Primarily based on the most recent URA personal property value index (PPPI) flash estimates, we know that the PPPI, which represents the overall real property price development, has dipped in 2013Q4.

Best master clock algorithm

The best master clock (BMC) algorithm performs a distributed selection of the best candidate clock based on the following clock properties:

Identifier
A universally unique numeric identifier for the clock. This is typically constructed based on a device's MAC address.
Quality
Both versions of IEEE 1588 attempt to quantify clock quality based on expected timing deviation, technology used to implement the clock or location in a stratum schema, although only V1 knows a data field stratum. PTP V2 defines the overall quality of a clock by using the data fields clockAccuracy and clockClass.
Priority
An administratively assigned precedence hint used by the BMC to help select a grandmaster for the PTP domain. IEEE 1588-2002 used a single boolean variable to indicate precedence. IEEE 1588-2008 features two 8-bit priority fields.
Variance
A clock's estimate of its stability based on observation of its performance against the PTP reference.

Synchronization

Through use of the BMC algorithm, PTP selects a master source of time for an IEEE 1588 domain and for each network segment in the domain.

Clocks determine the offset between themselves and their master.[7] Let the variable represent physical time. For a given slave device, the offset at time is defined by:

where represents the time measured at the clock at physical time , and represents the time measured at the master at physical time .

The master periodically broadcasts the current time as a message to the other clocks. Under IEEE 1588-2002 broadcasts are up to once per second. Under IEEE 1588-2008, up to 10 per second are permitted.

IEEE 1588 synchronisation mechanism and delay calculation

Each broadcast begins at time with a Sync message sent by the master to all the clocks in the domain. A clock receiving this message takes note of the local time when this message is received.

The master may subsequently send a multicast Follow_Up with accurate timestamp. Not all masters have ability to present an accurate timestamp in the Sync message. It is only after the transmission is complete that they are able to retrieve an accurate timestamp for the Sync transmission from their network hardware. Masters with this limitation use the Follow_Up message to convey . Masters with PTP capabilities built into their network hardware are able to present an accurate timestamp in the Sync message and do not need to send Follow_Up messages.

In order to accurately synchronize to their master, clocks must individually determine the network transit time of the Sync messages. The transit time is determined indirectly by measuring round-trip time from each clock to its master. The clocks initiate an exchange with their master designed to measure the transit time . The exchange begins with a clock sending a Delay_Req message at time to the master. The master receives and timestamps the Delay_Req at time and responds with a Delay_Resp message. The master includes the timestamp in the Delay_Resp message.

Through these exchanges a clock learns , , and

If is the transit time for the Sync message, and is the constant offset between master and slave clocks, then

and

Combining the above two equations, we find that

The clock now knows the offset during this transaction and can correct itself by this amount to bring it into agreement with their master.

One assumption is that this exchange of messages happens over a period of time so small that this offset can safely be considered constant over that period. Another assumption is that the transit time of a message going from the master to a slave is equal to the transit time of a message going from the slave to the master. Finally, it is assumed that both the master and slave can accurately measure the time they send or receive a message. The degree to which these assumptions hold true determines the accuracy of the clock at the slave device.[5]Primarily based on the most recent URA personal property value index (PPPI) flash estimates, we know that the PPPI, which represents the overall real property price development, has dipped in 2013Q4.
