DOCSIS is all on the cable infrastructure and the cable CPE device. Beyond that, it's all ethernet. Your router doesn't need to know squat about DOCSIS.

Routing requires a little CPU to look at each packet, modify it, figure out which direction it should go and send it on its merry way. The slowness probably has more to do with the routers CPU, often a 200MHz or slower MIPS core, than anything else. Consumer grade routers like this are often incapable of maintaining wirespeed. Manufacturers could get away with this because upstream bandwidth has been pretty limited, and in the case of wireless, the wireless layer was much slower than wired speeds. With 802.11n, that's becoming less true. Newer routers have been tending to use faster CPUs. You don't notice it so much on your local network because for local traffic your packets are hitting a relatively fast switch chip and don't have to ever talk to the underpowered CPU. -- Russell Senior, President [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
