Currently for the CMTS & Node Cable modems interact with a device called a cable modem termination system (CMTS). The CMTS is a router that speaks with all the cable modems and paths their traffic to the internet or the MOS’s foundation. There are a couple of different suppliers in the CMTS market but one of the most recognized is Cisco Systems.
Cable settings are commonly organized into regional nodes. A node is more than likely your neighborhood but could however a smaller or ale area the MSO utilizes to sustain all your services. The node is a fiber to RF converter which allows the MOS to send services to your location through fiber approximately the factor of your neighborhood service location and the solutions are sent over coax.

What does a router do What this means is that if you remain in a greatly crammed node and every person is downloading data you solution can reduce some. With how affordable the ISP company is most MSO’s will try to not oversubscribe nodes too much without including more nodes or splitting them.
Other things to watch out for is the security of the node. Make sure various other subscribers in your node are unable to see your computer and its web traffic.
