Re: 10Mbps versus 100Mbps Cable Modems
They probably did it because the number of subscribers has increased to the point that they need to start limiting bandwidth to ensure that everyone gets their fair share. They probably allowed subscribers to exceed their allotted max bandwidth while the number of subscribers was sufficiently low that they did not have to worry about it. Now that they have a lot of subscribers, they have to worry about it. --- Sten Daniel Soersdal [EMAIL PROTECTED] wrote: fbsd2 wrote: Comclark cable in Angeles City Philippines has changed from using 100Mbps Cable Modem to 10Mbps Cable Modem.

Re: 10Mbps versus 100Mbps Cable Modems
Yup..and it goes back to my original point. If it saves $5/box times 100,000 units and they charge you the same for the box rental/purchase, its a good business decision.

RE: 10Mbps versus 100Mbps Cable Modems
Am I missing some thing here? I though 10Mbps/100Mbps ends up controlling the max packet size traveling over the internet. So if your using 10Mbps, you end up generating 10 separate packets versus 1 packet at 100Mbps to move the same amount of data. This results in a network using 10Mbps to have more administrative overhead that a network using 100Mbps. This overhead on a heavily used network results in longer lag times in receiving replies. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The ethernet port being 10mbps is only a problem if your being sold more than 10mbps of bandwidth, in which case it would be a bottleneck. Since the cable provider is installing these modems it would seem they aren't trying to sell higher link speeds than that. -- Thanks, Josh Paetzel pgp5zutfXSGUj.pgp Description: PGP signature
Re: 10Mbps versus 100Mbps Cable Modems
Do you have more than 10Mbit/sec of cable internet bandwidth available? I dont see it as a problem if you dont, but if you have 20Mbit/sec of internet, then ya.. If it saves then $5 a unit, for 10,000 units, no harm.

RE: 10Mbps versus 100Mbps Cable Modems
Sure they have more than 10Mbps bandwidth. People who became subscribers during the first 4 years they were in business all got 100Mbps modems.

IIRC DOCSIS 2.0 only provided 30 million bps aggregate bandwidth, assuming the cable system used all available channels for data. Ethernet speed should not be confused with the cable wire speed. The obsolete 3-Com shark fin cable modem I had never delivered more than 1.5M bps out the ethernet port.
