Symmetricom Adds Precision Time Protocol (PTP) Features to SyncServer® S300/S350 Network Time Servers

Business Wire
Symmetricom®, Inc. (NASDAQ:SYMM), a worldwide leader in precise
time and frequency technologies, announced today that it has
incorporated IEEE 1588 PTP (precision timing protocol) capabilities
into its SyncServer® S300 and S350 network time server products.
PTP provides the enhanced time synchronization accuracy that is
quickly becoming mandatory for latency sensitive applications found
on LANs. The new PTP features for the SyncServer devices use
hardware based, packet-time stamping for nanosecond caliber
accuracy and precision, thereby making even more accurate time
synchronization possible for PTP clients on the network.
The new capabilities of the SyncServer S300/S350 network time
servers further enhance the SyncServer’s role as a comprehensive
time source for accurate, reliable and secure network timekeeping
operations. In addition, the SyncServer has proven PTP client
interoperability with FSMLabs’ TimeKeeper software for Linux and
the new Domain Time II PTP software for Windows. IT managers can
now quickly and easily deploy both the SyncServer and PTP client
software to accurately synchronize Linux and Windows-based machines
across the network.
Paul Skoog, product marketing manager for Symmetricom, noted,
“Newer low latency applications benefit from time accuracy greater
than that provided by traditional NTP. For those network architects
who are in the process of evaluating and deploying PTP to achieve
better time stamp accuracy, the SyncServer S300/S350 provides the
essential PTP features and the smoothest transition path from NTP
to PTP for their networks.”
Skoog added, “The beauty of the new PTP feature is that every
S300 Series SyncServer ever sold has hardware time stamping built
in. A simple software upgrade enables the new PTP functionality for
existing deployments while preserving the NTP capability already in
place. The PTP option also includes a new Time Interval measurement
on the S350 that is useful to measure the accuracy of
hardware-based PTP clients on the network. This technique verifies
the time-synchronization accuracy achieved over the network between
the SyncServer and a hardware based PTP client down to five
nanoseconds resolution.”
Jeffry Dwight, president of Greyware Automation Products, the
leading provider of time synchronization, management, and auditing
software for Windows, noted, "We chose the SyncServer 350 to
develop the PTP support in the Domain Time II software. The
ease-of-use, accuracy and reliability of the S350 is ideal for our
rigorous testing under various network conditions."
Symmetricom’s S300 and S350 SyncServers with PTP provide
extremely robust hardware time stamp accuracy servicing over 4000
delay request messages per second, all with less than 25 nanosecond
time stamp accuracy. Unlike software time stamping, hardware time
stamping removes all internal asymmetric paths delays and related
errors caused by the operating system. The result is far better
time synchronization accuracy between the SyncServer and the PTP
client.
The new PTP option for the S300/S350 SyncServers delivers best
of Enterprise class performance in a single NTP/PTP grandmaster
clock. The new features interoperate with IEEE 1588 PTP version 2
software slaves. The S300/S350 provides the following key PTP
features and benefits:
- A combination Enterprise NTP/PTP Time
Server providing a single time source for the network, for both PTP
and NTP clients.
- Nanosecond accurate PTP time stamps for
better computer-to-computer time synchronization.
- Tracking of PTP slave activity on the
SyncServer for assurance that PTP slaves are synchronizing.
- Performance monitoring of PTP traffic
load on the SyncServer for assurance that the server is servicing
all requests and is not overloaded.
- For the S350, time interval
measurements and statistics for measuring hardware-based PTP slave
accuracy relative to the SyncServer.
