05 Nov 09 Comcast's New Throttling Plan Uses Trigger Conditions, Not Silent Blocking

clang_jangle writes with this excerpt from The Inquirer outlining Comcast's new traffic-throttling scheme, based on information from Comcast's latest FCC filing. "Its network throttling implements a two-tier packet queueing system at the routers, driven by two trigger conditions. Comcast's first traffic throttling trigger is tripped by using more than 70 per cent of your maximum downstream or upstream bandwidth for more than 15 minutes. Its second traffic throttling trigger is tripped when the Cable Modem Termination System you're hooked-up to – along with up to 15,000 other Comcast subscribers – gets congested, and your traffic is somehow identified as being responsible. Tripping either of Comcast's high bandwidth usage rate triggers results in throttling for at least 15 minutes, or until your average bandwidth utilisation rate drops below 50 per cent for 15 minutes."

19 Dec 09 WiMax In 2010 — Too Little, Too Late?

CWmike writes "By the end of 2010, users in more than 80 US cities may be able to ditch their cable modems, T1 setups and DSL lines — and the Wi-Fi routers that go with them — in favor of WiMax wireless technology. Wait, haven't we heard that before? WiMax has been promised 'any day now' for years, but WiMax vendors such as Clearwire Communications LLC have suffered numerous delays in rolling out services. A recent ramp-up in Clearwire deployments bodes well for WiMax, but it may not have the chance to fully get off the ground before a competing technology called Long-Term Evolution (LTE) does it in. Craig Mathias, principal analyst at Farpoint Group and a Computerworld columnist, sees WiMax taking a minority stake in the wireless broadband future. 'LTE will eventually be a combined broadband voice/data solution that can do everything that WiMax can and more,' he said. Mathias believes that LTE could get up to 80% of the global market share in future cellular installations. 'This leaves WiMax with a potential market share that cannot exceed 20% — but that's still a huge number, assuming 4 billion users around 2020 or so," he said. 'You do the math. The opportunity is nothing to sneeze at.'"
