Cisco over the next five years plans to radically change how it sells and delivers router and switch software, in part by making that software more virtualized and modular.

Cisco’s intention is to decouple IOS software from the hardware it sells, which could let users add enhancements such as security or VoIP more quickly, without having to reinstall IOS images on routers and switches. The vendor also plans to virtualize many of its network services and applications, which currently are tied to hardware-specific modules or appliances.

This shift would make network gear operate more like a virtualized server, running multiple operating systems and applications on top of a VMware-like layer, as opposed to a router with a closed operating system, in which applications are run on hardware-based blades and modules. Ultimately, these changes will make it less expensive to deploy and manage services that run on top of IP networks, such as security, VoIP and management features, Cisco says.

High-level details of the road map were delivered in a session at Cisco’s C-Scape analyst conference last week in San Jose by Cliff Metzler, senior vice president of the company’s Network Management Technology Group.
