NYT today - Streaming protocols hijacking the web: Most text and graphics on WWW use TCP protocol, which is polite. On the other hand, streaming protocols use UDP protocol, which was designed more for short 'emergency' messages and therefore gets higher priority on a channel which carries both TCP and UDP traffic (both TCP and UDP ride on top of the IP protocol). The future crunch of undisciplined audio and video IP will cause a lot of problems. The answer (of course) is ATM, but ATM running right to the desktop, or at least to the home end of the cable modem or ADSL line. This is happening with the adoption of the G-Lite protocol (which bolts onto ATM). But there is a lot of IP hardware/software installed and still shipping. It is a bit like the controversy between DC power and AC power around 1880. As you may recall, the later technology - AC - had so many advantages that it won out in the end, but it was a battle. ------ polite: yes, but since it rides on top of IP, dumb. ----- From today's NYT business section: nytimes.com <<August 23, 1999 Multimedia Transmissions Drive Net Toward Gridlock By SARA ROBINSON Like a nation's highway system, the Internet has traffic rules that prevent chaos and gridlock. But an increasingly popular type of multimedia traffic is turning out to be a cyber road hog that flouts the rules and creates traffic jams. This scofflaw traffic, known as streaming media, is widely hailed as the future of home entertainment, capable of eventually delivering high-quality audio and video programming over the Internet. Unfortunately, network experts warn, it may drive everyone else off the road. >> <<Even elbowing all other data aside, today's streaming media produces a very low quality of entertainment most of the time. Much of that lack of quality today is a result of slow modems at the user's end. In three to five years, when cable modems and souped-up digital telephone lines are expected to be common, most Internet users may be listening to live Webcasts or playing high-quality radio on their computers. In 10 years, movies and commercial television might very well be carried over Internet channels. This increasing demand will add vast amounts of streaming traffic to the Internet and could lead to what Jacobson calls "congestion collapse" -- the Internet equivalent of gridlock. Internet service providers are also concerned.>>
