SUMMARY

This discussion focuses on download speeds across various internet connections, specifically comparing ADSL, T1, and OC lines. Users report maximum speeds of 60KB/s on ADSL 512K, 100KB/s on a burstable T1, and up to 400KB/s on college LANs. The formula for converting kilobits to kilobytes is clarified as Bits/8 = Bytes, exemplified by the calculation of 512kb yielding 60kB. Notably, users experienced speeds up to 1MB/s while connected to high-speed academic networks.

PREREQUISITES
  • Understanding of ADSL 512K and its limitations
  • Familiarity with T1 and OC line connections
  • Knowledge of data transfer units (bits vs. bytes)
  • Basic mathematical skills for speed calculations
NEXT STEPS
  • Research the differences between ADSL and fiber-optic connections
  • Learn about T1 and OC line specifications and performance
  • Explore the impact of network congestion on download speeds
  • Investigate high-speed academic networks and their infrastructure
USEFUL FOR

This discussion is beneficial for network engineers, IT professionals, and anyone interested in understanding internet connection speeds and performance optimization.

i know on ADSL 512K, which i am on now i get 60K a second maximum. I was just wondering what other connections people got and their download speed. i know it depends on traffic, and the servers, i mean what is the fastest download speed you got so far?

mine downloading from microsoft i think i got 75K a second and it stayed there at that speed for along time.
 
Computer science news on Phys.org
512K is kiloBITS (usually abbreviated kb), 60K is kiloBYTES (kB). So you are getting 480kB, which is very close to your max speed.
 
Russ...what is the formula that you use to get those figures? I can never remember how it works

18...I use a burstable T1 here at work and see up to 100kps. However, in my travels I have been to colleges that use different speed OC lines, and I've downloaded at up to 320kps.

Bits/8 = Bytes

512kb / 8kb/kB = 60kB

I was also on a good college lan and I once got 400kB (kilobytes/sec) in a download. Thats 2.4mb (megabits/sec). Smoking.
 
When I was an undergrad living on-campus, our dorms were part of the nice campus academic network... as such we automatically got routed through things like vBNS (hi-speed dedicated academic network) when contacting computers at other big universities. There were a few times I was downloading stuff from like Berkeley or MIT and getting speeds of around a megabyte/second -- could tell it was saturating the local 10BaseT ethernet. Pretty damn cool. ;)
