Cisco Systems is offering greater flexibility to users by improving the IOS (Internetwork Operating System) software...
used in its enterprise Catalyst 6500 core switch line.
The new IOS can separate core processes by allowing them to reside in their own memory space, to allow network traffic flow to continue even when other switch processes are down or are being worked on.
Such operating system modularity was first promised by Cisco 18 months ago, and will replace the current situation where network managers have to reboot their switches when upgrading them.
Cisco’s core switches sold to telcos and service providers already have modularity built into them.
