Network Time Protocol (NTP) is one of the oldest Internet protocols currently in use. NTP was developed to disseminate accurate time to clients around a computer network. Simple Network Time Protocol (SNTP) is a much less complex implementation of NTP. SNTP lacks many complex synchronisation algorithms used by NTP which makes it ideal for implementation on small computers.
This article describes the differences between NTP and SNTP. The article also describes when the SNTP protocol can be safely implemented in place of NTP. The article also descibes the differences between a NTP server and a SNTP server.
NTP protocol packets transferred between a NTP server and client are identical to SNTP packets. Each field in a NTP packet of information has a corresponding field in a SNTP packet. NTP protocol packets are entirely interchangeable with SNTP protocol packets. Infact a NTP server has no way of telling if a time request originated from a NTP or SNTP client.
The difference between the NTP and SNTP protocols is contained within the sophisticated routines used to implement the protocols. NTP has sophisticated routines designed to monitor multiple time references and decide which is the optimal reference. NTP constantly monitors multiple time references for jitter and offset and decides which is the best one to synchronise. NTP corrects time by slewing the system clock. The host's system clock is accelerated or decelerated to slowly bring it into line with an accurate external time reference. Large stepped time adjustments are avoided. NTP has complex synchronisation algorithms that calibrate the system clock to match the frequency of an accurate reference clock.
SNTP is a simplified sub-set of the algorithms used by the NTP protocol. SNTP steps the host computers system time rather than slowly slewing it towards the correct time. Adjusting the system time in steps can cause time critical applications problems. SNTP also lacks the functionality to monitor multiple NTP server reference clocks and decide on the optimal source of time. Instead it utilises a list of references and in the event of failure of a reference it moves on to the next.
The SNTP protocol is best suited to synchronizing computers at the extremities of a computer network. It is ideally suited to less powerful processors, such as micro-controllers and embedded systems, which do not require the accuracy of NTP. The complex algorithms of NTP may not be practically implemented on small computers. NTP is ideal for use in dedicated NTP server systems and synchronising large networks of computers. Here, accurate time may be of the utmost importance and the sophisticated routines employed by NTP will help maintain synchronization.
I will tell you now that building a business takes work. Yes, you know that, but do you really. Are you struggling right now, trying to make a success of what you are doing. Do you realize that there are simple things that you can do everyday to create a successful business? The same tactics do not work for everyone, so first you need to figure out what your strong points are and what your weak points are. The sooner you figure that out the better.
It is important that you develop success habits now. It isn't to late or to early, but develop them now because they mean ongoing success for the life of your business. The key to figuring out what these habits are is to know what your goals are. Envision them, don't just say you want to be a success, how do you want to be a success. What part of your business do you want to be successful at?
Talk to new people about what you do every chance you get. This is the simplest thing that you can do and it can pay off really big. This is what is known as networking. Networking doesn't just limit you to talking to people that are in your line of work, it is branching out. There isn't one person that you will ever meet that doesn't know someone that could use what it is you are doing. There have been a couple times that a client was referred to me by someone that I had met and talked with once or twice and that lead to this encounter where I just made a few thousand dollars.
Along with your business, talk about your product, seems to only make sense but many people skip this part. Thinking that talking about their business is enough. For example, say you work with a prepaid legal company. You can tell people everything in the world about the company and what it does and why it is important to have that type of coverage- but what do you sell. What products do you have that are going to fill a need for a person? That need can be real or created that all depends on how well you talk about your product and how well you know your product.
That is another key right there, know your product. You can be selling or working with the greatest product in the world, but if you can't tell a person about it intelligently you just killed that product and any hope that you had from making a sale.
You have a down line, people that you brought into the business to help you make more money. What are you doing to help them make money and become a success in the company. You have to give in order to receive, and really there is no greater sense of success then helping another person meet and achieve their goals. I have worked "with" many different MLMs and Networking companies and all of those people were great recruiters. They convinced me to come on board- but when I needed help to make a success of what I was doing, they were no where to be found. So why would I waste my time trying to make a business work, where those people got paid off what I was doing and they weren't there to help me.
I had no motivation to be a success with those people. I advise you take a moment and figure out how you are helping those people you brought on board. What motivation are you giving them to make the business work? Help them and it helps you. This may take some personal development and further education on your part, but it will pay off greatly in the end.
Yes, education and personal development. As that none of us are perfect or know everything, you can never turn your back on the opportunity to improve your self. Go to seminars, read books, read the literature that you receive from the different networking groups that you have joined. What, you haven't joined any networking groups. I suggest you stop reading now and find some to join. You are missing out on a wonderful success habit that will build ongoing success for you.
Most if not all companies hold weekly conference calls. Participate in them. How can you work for a company that you have no clue about what it going on in. Yes, it may take a few moments of your time, maybe an hour, but that time can help you increase your business. If you are serious about making your business a success then you will take the time and attend those calls.
The only person that can make your business a success is you. You have to put in the time and the effort. That time and effort is ongoing. Leave no leaf unturned. Try as many things as you can to improve your business. Remember that what worked for your co-worker won't necessarily work for you.
