What is Cable Broadband?
The cap on the downstream speed was introduced to allow for a better distribution of traffic and ensure that all our subscribers enjoy optimal performance from their cable modems. Cable Broadband's upstream limit is well above 56Kbps and is comparable to an ISDN service. This move is consistent with the residential cable modem services offered by many major operators in the world, including AT&T@Home in the US, and NTL in the UK.
The lower upstream limit of the cable modem is the result of its technological design as an asymmetric connectivity device and is not meant to run server-based applications. The caps are necessary for network operators to ensure that network usage will be at a consistent service level for all subscribers. Otherwise, a few ''heavy'' users could consume a lot more bandwidth at the expense of other users.
We assign dynamic IP addresses because these have a limited lifespan. Your IP address will automatically be renewed from time to time.
Yes. Your machine will be given a host name. It will be based on the IP address assigned to your computer, so in effect, it will also be dynamic.
Setting up of servers using cable modem is not allowed. This is because the DOCSIS 3.0 compliant cable modem is designed for home surfing and is not made for server hosting applications. Major operators like @Home in the U.S. similarly do not endorse connecting servers to their residential cable modem service.
It is safe to use as a LAN concept. However, users are responsible for implementing their own precautionary measures on their own computers.
Users are also advised to take the following added precautions:
- Disable their file and printer sharing options in their operating system.
- Do not software programmes which already have security problems.
- Be well-informed of security loopholes by subscribing to security sites on the Internet. Most of these subscriptions are free.
- Install a firewall on the computer. Free firewall software like Zonealarm can be easily downloaded from ZoneLabs. For more firewall reviews, please refer to zdnet to install anti-virus software and update the software regularly.
