Ever wondered what the difference is between NTP and SNTP? Want to know why you should choose one over the other? You’ll find the answers to these, and other questions, right here.
An in-depth insight into stratum levels and their connection with Network Time Protocol (NTP).
The importance of Network Time Protocol (NTP) is often underestimated, yet critical systems rely on it every day to function properly. Discover the 5 reasons why your computer network needs NTP.
Why is everyone raving about NTP? Because accurate time can safeguard your computer network and improve business efficiency. Discover six valid reasons for NTP time server use.
Accurate time is more crucial now that it has ever been before. While decades ago, having a wall clock a few minutes fast or slow was no big deal, however, in the modern age, with the internet and global communication, knowing the exact time is crucial for all sorts of organisations. Computer networks, for instance, need to be accurately synchronised to enable communication with other networks, and failing to do so can lead to all sorts of potential errors and problems. (more…)
Hospitals are large organisations. Hundreds of different health professionals work in the average hospital, and part of the good running and ability to provide care is to ensure good coordination. Because health care is based on multi-disciplinary teams, treatments, meetings, operations and procedures often require strict coordination to prevent wasting time and provide an efficient service. Making sure everybody has access to a synchronised and accurate time is part of this process, which is what makes precise and reliable digital wall clocks for hospitals so important. (more…)
Most of us know how useful the GPS network is. The Global Positioning System has changed the way we navigate on the road, and most modern cars are sold complete with some form of satellite navigation system already installed. However, the Global Positioning System is not only useful for satellite navigation; it has other uses too, especially as a source of accurate time for synchronising a computer network and other such technologies with the aid of a GPS network time server.
Need for Synchronisation
Time synchronisation is vital for all sorts of technologies, especially computer networks. Having different machines with a different time can lead to all sorts of untold problems, from data getting lost to simple things such as emails arriving before they were technically sent. Without accurate synchronisation or a network time server, it is nearly impossible to keep a network running smoothly and pinpoint errors and bugs.
Other technologies too need complete synchronicity. CCTV cameras, cash machines and safety systems such as air traffic control all have to be precisely synchronised. Imagine the chaos if your local cash machine told a different time from the one next to it. In effect, you could withdraw money from one machine, while the one next to it would consider a transaction that hadn’t happened yet, allowing you to withdraw the same amount again.
The Global Positioning System doesn’t actually transmit any positioning information. The reason that satellite navigational systems can work out accurate positioning is due to the time signals that the GPS satellites transmit. Onboard each GPS satellite is a couple of atomic clocks. These clocks transmit their times and exact position of the satellite and it’s this information, triangulated from three or more satellites that a navigational system uses to work out exactly where it is in the world.
Atomic clocks have to be used for this process because the signals are travelling at the speed of light. A one-second inaccuracy in the time signal would lead a satellite navigational system to be in error of over 300,000 km. And it’s a testament to the atomic clocks on GPS satellites that most sat nav systems are accurate to within a few metres.
GPS Network Time Server
Because of the accuracy of the GPS time signals, and the fact that the signal are available anywhere on the planet, the GPS network is ideal for use as a master time source for computer network time synchronisation. To synchronise a computer network or other technology systems to GPS time, all that is required is a GPS network time server.
GPS network time servers do all the work for you. By use of a rooftop antenna, the time server receives the GPS signal and distributes it around a network of machines. By use of time synchronisation protocols such as NTP (Network Time Protocol), all devices can be kept within a few milliseconds of the original GPS time source. And you don’t need multiple time servers for large networks either. A single device can synchronise hundreds of devices to GPS time.
GPS network time servers are simple to install, simple to use and can maintain millisecond accuracy for all sorts of technologies. Used by organisations as diverse as stock exchanges, air traffic control and banking systems, GPS time servers provide an efficient and cost effective solution to maintain network synchronicity.
Cloud computing has been foreseen as being the next big step in the development of information technology with more and more businesses and IT networks becoming cloud reliant and doing away with traditional methods.
The term ‘Cloud Computing’ refers to the use of on demand programs and services online including the storing of information over the internet, and using applications not installed on host machines.
Cloud computing mean that users no longer need to own, install and run software in individual machines, and doesn’t require large capacity storage. It also allows remote computing, enabling users to use the same services, work on the same documents, or access the network at any workstation able to log onto the cloud service.
While these advantages are appealing to businesses enabling them to lower IT costs while providing the same network capabilities, there are disadvantages to cloud computing.
Firstly, to work on the cloud you are reliant on a working network connection. If there is a problem with the line, whether in your locale or with the cloud service provider, you can’t work—even offline.
Secondly, peripherals such as printers and back up drives may not work properly on a cloud-orientated machine, and if you are using a non-specified computer, you won’t be able to access any network hardware unless the specific drivers and software are installed on the machine.
Lack of control is another issue. Being part of a cloud service means that you have to adhere to the terms and conditions of the cloud host, which may affect all sorts of issues such as data ownership and the number of users that can access the system.
Time synchronisation is essential for cloud services, with precise and accurate time needed to ensure that every device that connects to the cloud is logged accurately. Failure to ensure precise time could lead to data getting lost or the wrong version of a job overriding new versions.
To ensure precise time for cloud services, NTP time servers, receiving the time from an atomic clock, are used to maintain accurate and reliable time. A cloud service will essentially be governed by an atomic clock once it is synchronised to an NTP server, so no matter where users are in the world, the cloud service can ensure the correct time is logged preventing data loss and errors.
Leading providers of time synchronisation equipment and Network Time Protocol Products, Galleon Systems, have released a compact new 1U rackmountable dual time server.
Galleon’s new NTS 6001 1U rackmountable NTP time server can receive atomic clock timing signals from both the Global Positioning System (GPS) and national time and frequency radio transmissions.
