Thanks for eveyone's time today. @rmota @mpreath @rgruia #Ciscochat

[John T. Chapman @JChapmanCisco]

@mpreath Matt, we fully agree! Deliver customer value and make thie business plans work . #Ciscochat

[John T. Chapman @JChapmanCisco]

@rgruia Ronald, do you have a pointer to that study? #Ciscochat

[John T. Chapman @JChapmanCisco]

@mpreath Agreed. LTE-U may be a big enabler. #Ciscochat

[John T. Chapman @JChapmanCisco]

@rgruia @rmota With DOCSIS, we could create a gaming tier with lower latency. Not sure if anyone would pay for it.

[John T. Chapman @JChapmanCisco]

@LeslieEllisEdit @rmota Video loading is okay at the home (10-50 Mbps) but it is a big change for the IP backbone (Terabits!) #Ciscochat

[John T. Chapman @JChapmanCisco]

Agreed. Wireless is now a dominant in-home connectivity for data/voice/video. Drop to the home is next. #Ciscochat https://t.co/89axseEv1f

[John T. Chapman @JChapmanCisco]

A deeper fiber solution with incremental investment and returns could have a better ROI than a rebuild. #Ciscochat https://t.co/XoDMW7Trhl

[Ronald Gruia @rgruia]

We need a much better #broadband competitive environment (both in the US and Canada) in order to improve our global standing #CiscoChat

[John T. Chapman @JChapmanCisco]

After 50 Mbps, it is all about latency. Hard Disks run at 6 Gbps. Makes 50 Mbps look slow. #Ciscochat https://t.co/V1gvU6q46t

[John T. Chapman @JChapmanCisco]

Maybe we need Broadband over drones. New grass roots SP opportunity. #Ciscochat https://t.co/J4nECspEF4

[John T. Chapman @JChapmanCisco]

You are right. Many countries are smaller and have government funding. Here we need to do it ourselves. #Ciscochat https://t.co/NYsIkFT3dm

[Ronald Gruia @rgruia]

The US stats are not that great (26th globally in #BB download throughputs & 44th in upload speeds). #CiscoChat

[John T. Chapman @JChapmanCisco]

The technology is here. The challenge is profitable deployment for operators and value for customers. #Ciscochat https://t.co/XoDMW7Trhl

[John T. Chapman @JChapmanCisco]

With Agile DC, service creation will be quicker, more creative, and customized. Lots of value created #Ciscochat https://t.co/j69O0Y1wLj

[ray mota @rmota]

#Broadband offering from SPs are still about higher capacities and they look for bump in ARPU until DC's transform to more agile #CiscoChat

[John T. Chapman @JChapmanCisco]

There is a lot of buzz in the Cable Market about getting to a gigabit to customers. competition. #Ciscochat. https://t.co/09tmJZcj1T

[John T. Chapman @JChapmanCisco]

IoE focuses alot on low bandwidth, low cost and lots of connectivity. Opposite of the power user at home #Ciscochat https://t.co/Y985LLPJuu

[John T. Chapman @JChapmanCisco]

Virtualization - where physical networking products are replaced by SW on servers - will be huge. #Ciscochat https://t.co/AjVpTmhE8m

[ray mota @rmota]

As vCPE for enterprise and residential picks up #Broadband with higher speeds will be required since features are moving to DC #CiscoChat

[John T. Chapman @JChapmanCisco]

DOCSIS 3.0 systems this year deliver 300 - 500 Mbps this year. DOCSIS 3.1 takes us over 1 Gbps. #Ciscochat https://t.co/AjVpTmhE8m

[John T. Chapman @JChapmanCisco]

Hi Ray, Broadband is becoming the number 1 service in popularity and revenue instead of video. Big change #Ciscochat https://t.co/oaDSPcjuXv

[Cisco Service Provider @CiscoSP360]

@rmota would love to hear your thoughts on #broadband. Join us for our #CiscoChat now!

[John T. Chapman @JChapmanCisco]

The 187 page WP was on DOCSIS 3.0, which is coming to the world this year and next. Gigabit to the home! #Ciscochat https://t.co/zAnRrkLf88

[John T. Chapman @JChapmanCisco]

This year a 50 page white paper on the new Remote PHY architecture. Soon to be released by CableLabs. #Ciscochat. https://t.co/zAnRrkLf88
