[ninux-not-wireless] [Ninux-Wireless] Cisco nel Networking (was: Una nuova tecnologia che suona interessante)

Mon Apr 23 02:33:30 CEST 2012

O, se pensi che l'email sia troppo lunga e complottisticamente
complessa... beh... wikipediati:

"For Cisco's first product, Bosack adapted multiple-protocol router
software originally written some years before by William Yeager,
another Stanford employee who later joined Sun Microsystems." (
http://en.wikipedia.org/wiki/Cisco_Systems )

Che ricorda tanto quell'altra:

"Microsoft entered the OS business in 1980 with its own version of
Unix, called Xenix."
"Xenix is a discontinued version of the Unix operating system,
licensed by Microsoft from AT&T in the late 1970s."
"For this deal, Microsoft purchased a CP/M clone called 86-DOS from
Seattle Computer Products, branding it as MS-DOS, which IBM rebranded
to PC-DOS."

Non sono inventori. Sono droghieri. Pizzicagnoli. Pescivendoli.
Baracconari. Maneggiatori. La sola differenza tra loro e gli altri e'
aver avuto la benevolenza di chi gestiva le c.d. Ragioni di Stato.

ciao

P.s.: con tutto il rispetto, ovviamente, per i pescivendoli. Non per
niente ma sto a fa' il pescivendolo... e non c'ho le ragioni di stato
dalla mia...

> IP Traffic Direction: IETF Multiprotocol Label Switching
> Multiprotocol Label Switching (MPLS) is a highly scalable, Data Link
> Layer–independent delivery mechanism that directs and carries data from one
> network node to the next. Standards work commenced in 1996, and large-scale
> deployments of MPLS began in 2001. Cisco’s Tag Switching technology (first
> shipped in 1997) developed into Label Switching in collaboration with IBM
> Research. Label Switching then drove the final MPLS standard: a standard

> enterprise networks. Owing to this vital role MPLS plays within public and
> private networks, Cisco has released a number of books promoting the
> effective and secure use of MPLS.

> groundwork for the 802.3af PoE standard that was ratified in 2003. Cisco was
