Speeding Upstream

DOCSIS 3.0 Tips

By John Downey, Cisco Systems, and Brady Volpe, Volpe Firm

The first part of this article (in CT's March 2009 issue) discussed downstream potential issues, while this one focuses on the potential issues associated with upstream deployments. In particular, this article covers the critical upstream areas that one should be aware of when getting ready to deploy or already deploying DOCSIS 3.0.

The business objective for many operators today is to provide faster speeds to compete with Verizon's FiOS. These speeds are for downstream and upstream. DOCSIS 2.0 can provide approximately 37 Mbps on the downstream and 27 Mbps on the upstream, aggregate speed. Some per-cable modem speeds are approaching these peak rates and exceeding them. The only way to offer higher rates than what DOCSIS 2.0 can offer is to upgrade to DOCSIS 3.0. Instead of reducing node sizes, which can exceed $10,000 per node split, the business case can quickly be made to migrate to DOCSIS 3.0.

Mr. Volpe has over 25 years of communications industry experience. He is focused on the cable and telecom industry with deep technical and business skills. Mr. Volpe is currently the president and chief technologist of the Volpe Firm and holds an MSEE with honors.
