IEEE 1588 Time Protocol Promises More Accurate Time Synchronisation

By Jerry J. Jansen On December 7, 2009 No Comments

Despite being around for over twenty years, the current favoured time protocol by most networks, NTP (Network Time Protocol) has some competition.

Currently NTP is used to synchonise computer networks using network time servers (NTP servers). Currently NTP can synchronise a computer network to a few milliseconds.

The Precision Time Protocol (PTP) or IEEE 1588 has been developed for local systems requiring very high accuracy (to nano-second level). Currently this type of accuracy is beyond the capabilities of NTP.

PTP requires a master and slave relation ship in the network. A two-step process is required to synchronise devices using the IEEE 1588 (PTP). First, determination of which device is the master is required then the offsets and natural network delays are measured. PTP uses the Best Master Clock algorithm (BMC) to establish which clock on the network is the most accurate and it becomes the master whilst all other clocks become slaves and synchronise to this master.

IEEE (Institute of Electrical and Electronic Engineers) describes IEEE 1588 or (PTP) as 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 very high

SEO in the Web Design Process

By Jerry J. Jansen On December 7, 2009 No Comments

If you’re just starting to build your website now is the best time to start planning your search engine optimization and search engine marketing strategy. The best time to introduce the SEO planning of a website is when the web design is ready and the site is ready to be launched but there is no content yet for the site. Just before the site launches is the time to bring in an SEO consultant to provide some SEO services. After the design of the website is done an SEO consultant can give you suggestions about what keywords and key phrases you need to add into the site HTML as Meta tags and where those tags should go. Once the site is tagged and the design and navigation has been tested it’s time to add in content. Having SEO content on your site from the start will give your web site a big advantage over older websites that might already have a lot of a following but haven’t had any SEO services by a professional SEO consultant.

For a new site where that site ends up on the search engine results pages can be very important to its
