Packet Tracer for young advanced admins - ebook
The book: “PACKET TRACER FOR YOUNG ADVANCED ADMINS” is a collection of scenarios and network simulations for users who already have at least basic knowledge of computer networks and experience in the work associated with the administration of basic devices, as well as management of network architecture. The simulations were prepared in such a way as to develop the knowledge already presented in the previous books of Our Publishing House by Jerzy Kluczewski. The second goal, is to popularize the world-famous Packet Tracer program. This book is an excellent resource for students, undergraduates, and participants and graduates of CISCO CCNA networking courses. The themes of the book are very extensive and varied. Multiuser mode visualization, Bluetooth connections, cellular networks, WLAN controllers, industrial routers, IPV6 protocol, are just a few selected issues for which the author has prepared scenarios and ready-made simulation files that can be downloaded from the publisher's website. We encourage you to open the book and browse the table of contents for a broad overview of this book. The author of the publication is Jerzy Kluczewski, a long-time CISCO CCNA Academy instructor. He already has an extensive body of work in the form of published books on information technology. He gained his experience working in industry, and is currently a lecturer at the Gdansk School of Banking. Translation: Agata Skutela an experienced English teacher in Complex of Technical and General Schools in Tarnowskie Góry. Apart from English language she has also been teaching technical English. She is really into teaching and eager to expand her knowledge and workshop to be able to teach the best as she can.

FRAGMENT KSIĄŻKI
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.
Integrated Industrial Routers
Figure 8.2 Fog computing IOx - source (Cisco.live, 2019) ⁶
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.
