A rational debate on Comcast traffic management

Updated 8:00 PMThe discussion on Comcast actively resetting BitTorrent connections to manage its network for its cable broadband service has gotten hot in recent weeks and there hasn't been a whole lot of accurate reporting on the subject because of the complexity of the issue. The subject of Net Neutrality has once again surfaced with Comcast's actions being the latest rallying cry of Internet "discrimination".

Microsoft Unified Communications shuns G.722 wideband interoperability

Microsoft launched its UC (Unified Communications) products this month with the intention of replacing the traditional PBX.  But before it can get to a dominant market share position if it ever gets there at all, it's going to have to interoperate with existing telephony systems on the existing standards that are in place.

AT&T DSL 1.5 mbps service = 0.3 mbps throughput

AT&T DSL 1.5 mbps service = 0.3 mbps throughput

This hasn't been a kind week to me when it comes to DSL service from AT&T as I've already gone through AT&T DSL setup hell earlier this week.  On Saturday when I set up a few extra things for my mother's home, I ran some DSL speed tests (during non busy hours at a nearby test server at 19ms away) on the 768 kbps $15/month basic DSL service.

Microsoft blocks FairUse4WM v2 after 3 months of DRM free music

Just over a year ago when hacker “Viodentia" wrote FairUse4WM and broke Microsoft's Windows Media DRM scheme wide open, Microsoft responded with record urgency in a mere 3 days.

AT&T DSL setup hell - where did my public IP go?

AT&T DSL setup hell - where did my public IP go?

One of the things I've noticed in recent years is how a lot of people I know were getting pigeon holed in to non-public IP addresses by their broadband provider.  Oh sure you can do your typical web surfing and you could probably even put up a router to share your Internet connection, but that put you in to a situation where you have to do two address translations which breaks a lot of advanced applications.
