Both CPU and SW need to be considered
Hi Prayson,

Interesting article. One area that must be discussed as well is the amount of SW that needs to be loaded on these uCPEs. Between OTT VNFs and NFVI OS stacks, performance take a hit and the ability of the Carriers to add differentiaing, revenue generating, functionality is limited. The ARM approach to uCPE alleviates this situation in two ways :

1) More effecient offload of "plumbing level" loads (packet processing, Crypto\IPSEC, etc.) to dedicated HW accelerators on the SoC, freeing up uCPE cores for real revenue-generating functionality.

2) Ability to cost effectively scale in core count - while the relative portion of a 4 cores CPU in the total uCPE BOM might be small, it is not necessarily the case when moving to 8 cores. ARM architecure allows you to do just that without taking a big CAPEX hit.

As 5G networks begin to roll out, it is worth looking at how service providers can deliver high-value, high-margin security services in a way that no one else in the IoT ecosystem can match.
Operators that mainly serve prepaid customers must figure out a strategy for tackling churn.
The optical networking industry is at another inflection point, writes James Kisner, and the chalice some companies drink from next could point the way to everlasting revenue growth.
Like Lucy always does to Charlie Brown, 5G is likely another new technology that teased optical networking vendors with massive, sustained spending, then quickly yanked back expectations.
More acquisition activity in the optical space is inevitable, but it might not happen for a while until some newly coupled companies get to know each other just a little bit more.
