And if you trust the people on this site, then you know the the Splunk CEO is taking over from Chuck and will sell off parts of Cisco until it's gone.
They've been saying for many years that each layoff would cause everyone else to quit and the company has more employees than ever, so no, I don't trust them.
For all the speculation there hasn't been a hint of an explanation for why Cisco is significantly more valuable in parts. Cisco has already sold parts they couldn't execute on (all of Linksys, home cable routers, etc...) so I could see some smaller bits being split off to have a better chance in the market, but the core of the company is IOS-XE (which encompasses IOS,) IOS-XR, NX-OS and the associated hardware and services. Competitors likely won't want to support an entirely new OS, customers looking to starve out their competitors won't be able to manage the software maintenance and I don't see an entity entirely outside the networking market who would be able to radically improve the financial performance of any of those operating system ecosystems. Trying more fine grain sales with non-exclusive licensing opens up massive maintenance and legal problems.
IBM still does mainframes, HP still does printers, Oracle still does databases and there is a good chance Cisco will continue to do network plumbing parts well into the future.
