4 .Future of the Internet
Trying to predict the future of the Internet is not an easy task . Few would have imagined even say ,three years ago ,the extent to which the Internet has now become a part of everyday life in business ,homes and schools .There are a number of things ,however ,about which we can be fairly certain.
Bandwidth requirement will continue to increase at increase at massive rates ;not only is the number of Internet users growing rapidly ,but the applications being used are becoming more advanced and therefore need more bandwidth .this is the reason why the number of core(backbone)service providers has grown from four in 1995 to around 48 today (whereas the number of Internet connection providers has grown only moderately).However ,new technologies such as Dense Wave Division Multiplexing (DWDM)will help to get the most bandwidth from currently installed fiber.
Today it is possible to hear radio stations from almost any part of the globe via the Internet .Today this is at around AM quality. Soon FM-quality radio and video-on-demand will be driving the bandwidth requirement.
Many businesses have already completed an experimental period of Internet access and are moving towards using the Internet for serious business use both intra- and inter-company.
This has been made possible by the rapid advances in TCP/IP security technologies made in only the last one to two years. In the not too distant future ,the availability of private ,secure high bandwidth networking from Internet providers may well make many companies question the feasibility of their current in-house wide area networks.
Today we already have Voice over IP technology .As this technology matures we are almost certain to see a sharing of bandwidth between voice and data across the Internet. This raises some interesting questions for phone companies .The cost to a user of an Internet connection between New York and Japan is the same as a connection within New York-not so a phone connection .This ,and the fact that the Internet is deregulated ,will raise many interesting questions in the years to come.
