Networking fundamentals required for ITOM

[KhasimKhanP]

Hi folks,

Which networking fundamentals are essential before starting in IT Operations Management (ITOM)?

[Nikhil Bajaj9]

Hi @KhasimKhanP ,

For IT operations management (ITOM), essential networking fundamentals include understanding core devices like routers and switches, data communication concepts, and various network protocols such as HTTP, TCP, and SNMP. A grasp of the OSI model, TCP/IP, NAT, load balancing, and VPNs is crucial for managing network infrastructure, ensuring reliability, and facilitating communication between devices and external networks like the internet.

@KhasimKhanP 

Basic Computing & Networking fundamentals would help you with ServiceNow ITOM especially with Discovery and Service Mapping modules. 

Networking background is not mandatory for implementation of ServiceNow ITOM but would definitely be an added advantage to discuss with Client Stakeholders to understand their network architecture and provide recommendations for placement of MID Servers for Discovery and Service Mapping, network and firewall pre-requisites for implementation and configuration.

As per community guidelines, you can accept more than one answer as accepted solution. If my response helped to answer your query, please mark it helpful & accept the solution.

Thanks,

Hi @KhasimKhanP You should required basic knowledge 

Core Networking Concepts

• Routers and Switches:

  Understand the basic functions of these essential devices, which facilitate communication within a network and with external networks like the internet. 
• OSI Model:

  Learn the 7-layer model to understand the various functions of network communication, from physical connections to application-level services. 
• TCP/IP Model:

  This model is a practical implementation of network communication, and knowledge of its protocols is crucial for data transfer and network management. 

Essential Protocols and Technologies

• HTTP:

  Understand how this protocol facilitates communication between web browsers and servers, essential for managing web-based services. 
• TCP:

  Learn about the Transmission Control Protocol, a key component of the TCP/IP suite, which provides reliable, ordered, and error-checked delivery of data. 
• SNMP:

  Know how the Simple Network Management Protocol is used to monitor and manage network devices and services. 
• NAT (Network Address Translation):

  Understand this technology, which is used to translate private IP addresses to public ones, a fundamental aspect of internet connectivity. 
• Load Balancing:

  Be familiar with load balancing to distribute network traffic across multiple servers or resources, ensuring high availability and optimal performance. 
• VPNs (Virtual Private Networks):

  Learn how VPNs create secure, encrypted connections for remote access or to connect different networks, vital for a hybrid workforce
