Cable vs DSL

Posts: 44 · Posted: Mon Jul 07, 2003 2:40 am Post subject:

I'll add my 2 pennys worth to the discussion
I have 2 cable modems and a DSL line at home - I've used the Vonage on both.

Cable line #1 - 2048/256
Cable line #2 - 512/128
Cable line #3 - 512/256

I've tried the Vonage on all - and it seems great regardless of which it's on.

My traceroutes look as follows

Pretty similar regardless of which connection is used. Over here (I'm in the UK if you didnt catch on all ready) - cable has much less latency than Cable - I guess thats because all our cable networks have been put in within the past 5 years pretty much - so most, if not all are fibre right up to the neighbourhood level.

Incidentially - most of the latency you see above comes from level3 - on the transatlantic side of things.
On my ISP in london - we have a 100mb link to Level3 - and traces look like this...

Anyhow - hope someone can make sense of all that Smile
