Bufferbloat: Dark Buffers in the Internet

CowboyRobot (671517) writes | more than 2 years ago

The Internet 1

CowboyRobot writes "Jim Gettys at Bell Labs makes the case that the Internet is in danger of collapse due to 'bufferbloat', "the existence of excessively large and frequently full buffers inside the network"
Part of the blame is due to overbuffering; in an effort to protect ourselves we make things worse. But the problem rusn deeper than that.
Gettys solution is AQM (active queue management) which is not deployed as widely as it should be.
"We are flying on an Internet airplane in which we are constantly swapping the wings, the engines, and the fuselage, with most of the cockpit instruments removed but only a few new instruments reinstalled. It crashed before; will it crash again?""

Windows XP vs modern operating systems (1)

urbanheretic (1138845) | more than 2 years ago | (#38232928)

At the end of the article, the author mentions "Windows XP does not enable TCP window scaling, so it never has more than 64 KB in flight at once", while implying that modern operating systems do not have this constraint. This reminded me of some of the complaints that came out when Windows Vista was released. There were widespread complaints that a previously functional network would immediately start to move to about 10% of it's speed when Vista was installed. This article makes me think that maybe Microsoft wasn't to blame for this behaviour. Pity the most annoying problems are generally the ones that are nested very deeply.
