      "The MIB module for PTPv2 (IEEE1588 - 2008)
    
    Overview of PTPv2 (IEEE 1588-2008)
    
    This IEEE standard defines a protocol enabling precise
    synchronization of clocks in measurement and control systems
    implemented with packet-based networks, the IEEE Standard PTPv2
    1588 (2008). This MIB does not address the standard IEEE
    1588 (2002). The protocol is applicable to network elements
    communicating using IP. The protocol enables heterogeneous
    systems that include clocks of various inherent precision,
    resolution, and stability to synchronize to a grandmaster
    clock.
    The protocol supports system-wide synchronization accuracy in
    the sub-microsecond range with minimal network and local clock
    computing resources. The standard uses UDP/IP. It includes
    formal mechanisms for message extensions, higher sampling
    rates, correction for asymmetry, a clock type to reduce error
    accumulation in large topologies, and specifications on how to
    incorporate the resulting additional data into the
    synchronization protocol. The standard defines conformance and
    management capability also.

    Definitions from [1] section 3.1
    
    Accuracy:
    The mean of the time or frequency error between the clock under
    test and a perfect reference clock, over an ensemble of
    measurements.  Stability is a measure of how the mean varies
    with respect to variables such as time, temperature, and so on.
    
    The precision is a measure of the deviation of the error from
    the mean.
    
    Atomic process:
    A process is atomic if the values of all inputs to the process
    are not permitted to change until all of the results of the
    process are instantiated, and the outputs of the process are
    not visible to other processes until the processing of each
    output is complete.
    
    Boundary clock:
    A clock that has multiple Precision Time Protocol(PTP) ports in
    a domain and maintains the timescale used in the domain.  It
    may serve as the source of time, i.e., be a master clock, and
    may synchronize to another clock, i.e., be a slave clock.
    
    Boundary node clock:
    A clock that has multiple Precision Time Protocol(PTP) ports in
    a domain and maintains the timescale used in the domain. It
    differs from the boundary clock in that the clock roles can
    change.
    
    Clock:
    A node participating in the Precision Time Protocol (PTP) that
    is capable of providing a measurement of the passage of time
    since a defined epoch.
    
    Domain:
    A logical grouping of clocks that synchronize to each other
    using the protocol, but that are not necessarily synchronized
    to clocks in another domain.
    
    End-to-end transparent clock:
    A transparent clock that supports the use of the end-to-end
    delay measurement mechanism between slave clocks and the master
    clock.  Each node must measure the residence time of PTP event
    messages and accumulate it in Correction Field.
    
    Epoch:
    The origin of a timescale.
    
    Event:
    An abstraction of the mechanism by which signals or conditions
    are generated and represented.
    
    Foreign master:
    An ordinary or boundary clock sending Announce messages to
    another clock that is not the current master recognized by the
    other clock.
    
    Grandmaster clock:
    Within a domain, a clock that is the ultimate source of time
    for clock synchronization using the protocol.
    
    Holdover:
    A clock previously synchronized/syntonized to another clock
    (normally a primary reference or a master clock) but now
    free-running based on its own internal oscillator, whose
    frequency is being adjusted using data acquired while it had
    been synchronized/syntonized to the other clock.  It is said to
    be in holdover or in the holdover mode, as long as it is within
    its accuracy requirements.
    
    Link:
    A network segment between two Precision Time Protocol ports
    supporting the peer delay mechanism of this standard.  The peer
    delay mechanism is designed to measure the propagation time
    over such a link.
    
    Management node:
    A device that configures and monitors clocks.
    
    Master clock:
    In the context of a single Precision Time Protocol
    communication path, a clock that is the source of time to which
    all other clocks on that path synchronize.
    
    Message timestamp point:
    A point within a Precision Time Protocol event message serving
    as a reference point in the message.  A timestamp is defined by
    the instant a message timestamp point passes the reference
    plane of a clock.
    
    Multicast communication:
    A communication model in which each Precision Time Protocol
    message sent from any PTP port is capable of being received and
    processed by all PTP ports on the same PTP communication path.
    
    Node:
    A device that can issue or receive Precision Time Protocol
    communications on a network.
    
    One-step clock:
    A clock that provides time information using a single event
    message.
    
    On-pass support:
    Indicates that each node in the synchronization chain from
    master to slave can support IEEE-1588.
    
    Ordinary clock:
    A clock that has a single Precision Time Protocol port in a
    domain and maintains the timescale used in the domain.  It may
    serve as a source of time, i.e., be a master clock, or may
    synchronize to another clock, i.e., be a slave clock.
    
    Parent clock:
    The master clock to which a clock is synchronized.
    
    
    Peer-to-peer transparent clock:
    A transparent clock that, in addition to providing Precision
    Time Protocol event transit time information, also provides
    corrections for the propagation delay of the link connected to
    the port receiving the PTP event message.  In the presence of
    peer-to-peer transparent clocks, delay measurements between
    slave clocks and the master clock are performed using the
    peer-to-peer delay measurement mechanism.
    
    
    Phase change rate:
    The observed rate of change in the measured time with respect
    to the reference time.  The phase change rate is equal to the
    fractional frequency offset between the measured frequency and
    the reference frequency.
    
    PortNumber:
    An index identifying a specific Precision Time Protocol port on
    a PTP node.
    
    Primary reference:
    A source of time and or frequency that is traceable to
    international standards.
    
    Profile:
    The set of allowed Precision Time Protocol features applicable
    to a device.
    
    Precision Time Protocol communication:
    Information used in the operation of the protocol, transmitted
    in a PTP message over a PTP communication path.
    
    Precision Time Protocol communication path: The signaling path
    portion of a particular network enabling direct communication
    among ordinary and boundary clocks.
    
    Precision Time Protocol node:
    PTP ordinary, boundary, or transparent clock or a device that
    generates or parses PTP messages.
    
    Precision Time Protocol port:
    A logical access point of a clock for PTP communications to the
    communications network.
    
    Recognized standard time source:
    A recognized standard time source is a source external to
    Precision Time Protocol that provides time and/or frequency as
    appropriate that is traceable to the international standards
    laboratories maintaining clocks that form the basis for the
    International Atomic Time and Universal Coordinated Time
    timescales.  Examples of these are Global Positioning System,
    NTP, and National Institute of Standards and Technology (NIST)
    timeservers.
    
    Requestor:
    The port implementing the peer-to-peer delay mechanism that
    initiates the mechanism by sending a Pdelay_Req message.
    
    Responder:
    The port responding to the receipt of a Pdelay_Req message as
    part of the operation of the peer-to-peer delay mechanism.
    
    Synchronized clocks:
    Two clocks are synchronized to a specified uncertainty if they
    have the same  epoch and their measurements of the time of a
    single event at an arbitrary time differ by no more than that
    uncertainty.
    
    Syntonized clocks:
    Two clocks are syntonized if the duration of the second is the
    same on both, which means the time as measured by each advances
    at the same rate. They may or may not share the same epoch.
    
    Time of Day:
    
    
    Timeout:
    A mechanism for terminating requested activity that, at least
    from the requester's perspective, does not complete within the
    specified time.
    
    Timescale:
    A linear measure of time from an epoch.
    
    Traceability:
    A property of the result of a measurement or the value of a
    standard whereby it can be related to stated references,
    usually national or international standards, through an unbroken
    chain of comparisons all having stated uncertainties.
    
    Translation device:
    A boundary clock or, in some cases, a transparent clock that
    translates the protocol messages between regions implementing
    different transport and messaging protocols, between different
    versions of IEEE Std 1588-2008/IEC 61588:2009, or different
    Precision Time Protocol profiles.
    
    transparent clock:
    A device that measures the time taken for a Precision Time
    Protocol event message to transit the device and provides this
    information to clocks receiving this PTP event message.
    
    Two-step clock:
    A clock that provides time information using the combination of
    an event message and a subsequent general message.
