Advent Networks Ultraband Boosts Cable IP Performance
Startup Advent Networks on Wednesday announced a line of Ultraband switches that promise business customers 40 percent more bandwidth than a T1 line at a little more than half the cost.ANAHEIM, CALIF.Corporations looking for alternatives to expensive T1 service may soon get benefits from an unlikely placecable TV operators. At the cable industrys Western Show 2003 here on Wednesday, networking startup Advent Networks Inc. of Austin, Texas, showed off its new Ultraband line of switch routers, designed to let cable operators increase cable modem bandwidth from 2 to 10 or more megabits per second. Advents new Ultraband 8800 works by layering time-division multiplexing on top of a standard DOCSIS-based cable plant. According to President and CEO Geoffrey Tudor, that provides more bandwidth for each user by eliminating overhead, as well as guaranteeing packet delivery.
"Our latency is never over 1.5 milliseconds", Tudor said, which is much better than traditional cable modem plants. Guaranteeing packet delivery will let services such as IP telephony and even HDTV video be delivered via IP, rather than through traditional means.
