8 Integrated Industrial Routers

8.1 DESCRIPTION OF INTEGRATED ROUTERS Industrial integrated routers, in addition to supporting Wi-Fi, wired networks, also have support for fourth-generation integrated wireless WANs (4G LTE) and also support Machine-to-Machine (M2M) applications.

Part 1. A brief description of the Cisco IOx environment.

The Cisco IOx application environment is a combination of Cisco IOS and Linux OS to provide higher network security.

Figure 8.1 Cisco IOx application environment - source (Cisco.live, 2019) ⁵

Fog computing is a decentralized computing framework placed between the cloud and end devices. It allows users to place resources, including applications and the data they generate, in physical locations to increase performance.

In the 819 series routers, individual software components run in two CPU cores:

 in core 0 (Core 0) runs IOS,

 Core 1 runs the so-called Host OS, the so-called hypervisor, and applications.

The industrial integrated router models implemented in Packet Tracer are:

 Router 819HG-4G-IOX

 Router 819HGW

Part 4. A brief description of the 819HG-4G-IOX router.

The 819HG-4G-IOX router supports Machine-to-Machine (M2M) applications and cellular network services.

Figure 8.4 View of 819HG-4G-IOX

The 819IOX router comes standard with two antennas and non-replaceable MODULES:

 one GigabitEthernet0 interface,

 four ( FastEthernet0 – FastEthernet3 ) interfaces,

 one Serial0 serial communication interface,

 one Ethernet1 interface,

 one VirtualPortGroup0 ,

 one Cellular0 interface .

Part 5. Brief description of the 819HGW router.

The Cisco 819HGW (Integrated Services Router), is a variation of the 819 router model that supports Machine-to-Machine (M2M) applications and cellular network services.

The 819HGW router comes standard with five antennas and non-replaceable:

 one GigabitEthernet0 interface,

 four ( FastEthernet0 – FastEthernet3 ) interfaces,

 one Serial0 serial communication interface,

 one Ethernet1 interface,

 one Wlan-Gigabitethernet0 wireless interface,
