Mike Tennent of Tavcom Training responds to “Dont go hybrid” by Mark Harraway of Controlware.
A simple analogy is that TCP resembles the sending of a registered envelope to a customer who must acknowledge receipt of the consignment with a signature. UDP is like sending an ordinary letter … you never really know if it arrives! So, in essence, this is really no different, in transmission terms, from coaxial cable, optical fibre, twisted pair, microwave, laser or other free space methods.
I suppose cynically-minded people would identify IP as Beauty and the Beast rolled into one! The beauties of IP are that today’s world is increasingly computer-based, the infrastructure of cable is built in, the young people of today are largely computer literate and the transfer of information from computer to computer is so much easier and quicker to perform than old, traditional methods of tape. The beastly part of the analogy is the inability to get a picture from A to B as quickly as you can on many other other forms of transmission. IP produces some form of latency (delay) across the newtwork. This may be perfectly acceptable to many but totally inappropriate in other cases. There is also an issue as to how many cameras can be used on one system at a time.
