COMCAST, the second-largest US cable television and Internet communications service provider, has a new broadband traffic throttling scheme installed and operating in all of its markets.
The ISP's new regime for restricting its customers' bandwidth utilisation replaces its former stealthy practice of arbitrarily blocking subscribers' peer-to-peer (P2P) upload traffic, which was criticised by the FCC last year after it was exposed by the Associated Press and others.
Comcast's filing with FCC (PDF) says it has put in new hardware and software technology at its Regional Network Routers locations to effect this cunning traffic management plan.
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.
