A1 - Everyone wants higher bandwidth speeds. Security is on everyone's mind. And over the top OOT. #Ciscochat x.com/LeslieEllisEdi…

The 187 page WP was on DOCSIS 3.0, which is coming to the world this year and next. Gigabit to the home! #Ciscochat x.com/LeslieEllisEdi…

Hi Ray, Broadband is becoming the number 1 service in popularity and revenue instead of video. Big change #Ciscochat x.com/CiscoSP360/sta…

DOCSIS 3.0 systems this year deliver 300 - 500 Mbps this year. DOCSIS 3.1 takes us over 1 Gbps. #Ciscochat x.com/rmota/status/5…

Virtualization - where physical networking products are replaced by SW on servers - will be huge. #Ciscochat x.com/rmota/status/5…

IoE focuses alot on low bandwidth, low cost and lots of connectivity. Opposite of the power user at home #Ciscochat x.com/LeslieEllisEdi…

There is a lot of buzz in the Cable Market about getting to a gigabit to customers. competition. #Ciscochat. x.com/LeslieEllisEdi…

With Agile DC, service creation will be quicker, more creative, and customized. Lots of value created #Ciscochat x.com/rmota/status/5…

The technology is here. The challenge is profitable deployment for operators and value for customers. #Ciscochat x.com/rgruia/status/…

You are right. Many countries are smaller and have government funding. Here we need to do it ourselves. #Ciscochat x.com/rgruia/status/…

A deeper fiber solution with incremental investment and returns could have a better ROI than a rebuild. #Ciscochat x.com/rgruia/status/…

Agreed. Wireless is now a dominant in-home connectivity for data/voice/video. Drop to the home is next. #Ciscochat x.com/mpreath/status…
