What is IoX ?
Fog computing concept
Cisco IoX hosts applications in a virtual machines running on a hypervisor hosted on an IoX capable hardware called fog node. Cisco IoX is delivered with a pre-packaged Yocto Linux distribution but developpers are free to use any operating system. Yocto has been selected by Cisco because of it's various CPU architectures support, it's comprehensive SDK, and it's slim design to work on resource constraint platforms like routers.
All Cisco fog nodes have converged compute, networking and storage, which simplifies management and reduces power and space requirements and makes possible to run the same application on different kind of fog nodes without modification :
- Cisco ISR router (ISR 819HG-4G-IOX router simulated in Cisco Packet Tracer 7.0
- Cisco switch
- Cisco Unified Computing System (UCS) servers
Data and application access is protected by classical Cisco security mecanism. For example, IoX applications hosted on an ISR router benefit from Netflow to help detect anormal activity and CBAC to inspect to inspect and restrict the network flows. These two security mecanism can be simulated in Cisco Packet Tracer 7.0
Cisco IoX use cases
The main use case of IoX is local interaction with IoT industrial devices.
Example :A manufacturer could use Cisco IoX to host Rokwell Factory software on factory-floor routers. Using Cisco IoX API, the software could communicate with the factory IoT devices running any proprietary protocol. A second fog application could send IoT data to the enterprise cloud network by translating the non-standard or proprietary protocol to IP.
