Comcast Upskills U on Gigabit & DOCSIS 3.1Comcast Upskills U on Gigabit & DOCSIS 3.1
Comcast's Ty Pearman and Saif Rahman tackle the challenges and benefits of DOCSIS 3.1 in a live session at Upskill U.
October 7, 2016
As the cable industry ramps up to gigabit speeds with DOCSIS 3.1 deployments, cable providers continue to grapple with challenges to these deployments, including HFC network upgrades, splitting nodes, switching RF optics, OSS and lack of spectrum.
In the final course in Upskill U's Gigabit series, "Gigabit & DOCSIS 3.1," Upskill U will cover the benefits and challenges of DOCSIS 3.1 deployments in a live session today at 1:00 p.m. ET. Ty Pearman, director of access architecture for Comcast Corp. (Nasdaq: CMCSA, CMCSK); Saifur Rahman, distinguished engineer at Comcast Cable; and Alan Breznick, Cable/Video Practice Leader at Light Reading, will examine the pros and cons of DOCSIS 3.1, and address the impact of SDN/NFV and software-based networking on the cable industry. (Register for Gigabit & DOCSIS 3.1.) Figure 1: Ty Pearman, director of access architecture for Comcast, delivers the final course in Upskill U's Gigabit series with co-presenters Saifur Rahman, distinguished engineer at Comcast Cable, and Alan Breznick, cable/video practice leader at Light Reading (not pictured). On Wednesday, Joe Kochan, COO and co-founder of US Ignite , addressed the impact of advanced networks on the emergence of smart cities in the Upskill U course "Gigabit & Smart Cities." Kochan explained how advanced networks are fundamental to supporting growth in public and private arenas in smart communities by leveraging new technologies that advance power management, VR, transportation, academics and more. (Listen to Gigabit & Smart Cities.) "Underlying this whole thing, the cornerstone, the foundation of it all, is an advanced network. What we found at US Ignite is that without an advanced network it is very difficult to imagine that you could just go buy a bunch of sensors off a shelf, have an analytic engine and storage engine locally and get the data from those sensors to the storage and back again with the qualities that you need to really have a smart city." Kochan highlighted three key technologies or factors foundational to a smart city, which include ubiquitous, small sensors connected via local storage and compute, and supported by a low latency, highly reliable broadband network. These factors support "smart, adaptive, responsive systems" where data is rapidly gathered and analyzed for faster decision-making, said Kochan.
