Reasons why Network Automation is Important to learn for Network Engineers

Companies today are constantly pursuing greater agility and speed in their IT operations. By innovating with new technologies and adapting rapidly to changing consumer dynamics, they are seeking to seize market advantage.

In the quest for productivity, a big roadblock many companies face is that their business network is much more difficult to navigate than ever before. Distributed workloads and distributed IT resources have resulted in highly complex configurations and low environment-wide visibility.
What is network automation?

The process of automating the configuration, management, testing, implementation and operation of physical and virtual devices within a network is network automation. Network service availability increases with regular network operations and functions that are automatically monitored and handled by automated and repetitive processes.

Any type of network such as data centers, service providers, and enterprises can use network automation to increase efficiency, reduce man made errors, and lower operating expenses.

Why network automation is important?

The rise in IT costs for network operations is one of the main problems for network engineers. Data and system growth is beginning to outpace IT capacities, rendering manual approaches almost impossible.
However, up to 95% of network adjustments are made manually, resulting in maintenance costs that are 2 to 3 times higher than network costs. For companies to keep pace in the modern world, increased IT automation, centrally and remotely controlled, is important.

#1 Manual Tasks Removal: Automating the network substitutes predictable, repeatable network adjustments for manual tasks. That improves the competitiveness of IT, so you can concentrate on strategic opportunities that drive business growth.

#2 Accelerate delivery of service: A crucial advantage: delivering faster key data services, improving network performance, and speeding up the implementation of new services and applications.

#3 Templates standardize procedures: Use structured templates to drive performance and streamline network changes among network stakeholders.

#4 Enable fast improvements: Network modifications that you previously rarely performed because they were manual, time consuming, and resource intensive are more regularly implemented.

#5 Build a network that is secure: Using an infrastructure-as-code method to preserve the network’s state and configuration, from data centre to edge, in much the same way that source code is handled by developers.

#6 Gain visibility on the network: To detect performance problems, spiking resource consumption levels, and network failures, access wide-ranging performance monitoring capabilities.

#7 Analyze and fix problems: For insight into efficiency, usage, protection, and resource allocation, depend on network analytics that help solve problems much faster than through manual techniques.

Conclusion:
The number and type of devices, users and objects that are connected to the network has grown exponentially. And to satisfy this growing demand, networks are becoming more complicated and implementations are becoming huge. In addition to simplifying the Day one implementation process, Network Automation plays a very crucial role in simplifying day-to-day operations & maintenance.

These are the major reasons why enterprises are looking to hire IT professionals with network automation skills. That’s why; there is big demand of automation course for network engineers these days. You can quickly and easily plan, supply, and enforce policies across your network with network automation for your organization.

Autonomous Driving Network (ADN) On Its Way

Talking about inspiration in the networking industry, nothing more than Autonomous Driving Network (ADN). You may hear about this and wondering what this is about, and does it have anything to do with autonomous driving vehicles? Your guess is right; the ADN concept is derived from or inspired by the rapid development of the autonomous driving car in recent years.

Image for post

Driverless Car of the Future, the advertisement for “America’s Electric Light and Power Companies,” Saturday Evening Post, the 1950s.

The vision of autonomous driving has been around for more than 70 years. But engineers continuously make attempts to achieve the idea without too much success. The concept stayed as a fiction for a long time. In 2004, the US Defense Advanced Research Projects Administration (DARPA) organized the Grand Challenge for autonomous vehicles for teams to compete for the grand prize of $1 million. I remembered watching TV and saw those competing vehicles, behaved like driven by drunk man, had a really tough time to drive by itself. I thought that autonomous driving vision would still have a long way to go. To my surprise, the next year, 2005, Stanford University’s vehicles autonomously drove 131 miles in California’s Mojave desert without a scratch and took the $1 million Grand Challenge prize. How was that possible? Later I learned that the secret ingredient to make this possible was using the latest ML (Machine Learning) enabled AI (Artificial Intelligent ) technology.

Since then, AI technologies advanced rapidly and been implemented in all verticals. Around the 2016 time frame, the concept of Autonomous Driving Network started to emerge by combining AI and network to achieve network operational autonomy. The automation concept is nothing new in the networking industry; network operations are continually being automated here and there. But this time, ADN is beyond automating mundane tasks; it reaches a whole new level. With the help of AI technologies and other critical ingredients advancement like SDN (Software Defined Network), autonomous networking has a great chance from a vision to future reality.

In this article, we will examine some critical components of the ADN, current landscape, and factors that are important for ADN to be a success.

The Vision

At the current stage, there are different terminologies to describe ADN vision by various organizations.
Image for post

Even though slightly different terminologies, the industry is moving towards some common terms and consensus called autonomous networks, e.g. TMF, ETSI, ITU-T, GSMA. The core vision includes business and network aspects. The autonomous network delivers the “hyper-loop” from business requirements all the way to network and device layers.

On the network layer, it contains the below critical aspects:

  • Intent-Driven: Understand the operator’s business intent and automatically translate it into necessary network operations. The operation can be a one-time operation like disconnect a connection service or continuous operations like maintaining a specified SLA (Service Level Agreement) at the all-time.
  • **Self-Discover: **Automatically discover hardware/software changes in the network and populate the changes to the necessary subsystems to maintain always-sync state.
  • **Self-Config/Self-Organize: **Whenever network changes happen, automatically configure corresponding hardware/software parameters such that the network is at the pre-defined target states.
  • **Self-Monitor: **Constantly monitor networks/services operation states and health conditions automatically.
  • Auto-Detect: Detect network faults, abnormalities, and intrusions automatically.
  • **Self-Diagnose: **Automatically conduct an inference process to figure out the root causes of issues.
  • **Self-Healing: **Automatically take necessary actions to address issues and bring the networks/services back to the desired state.
  • **Self-Report: **Automatically communicate with its environment and exchange necessary information.
  • Automated common operational scenarios: Automatically perform operations like network planning, customer and service onboarding, network change management.

On top of those, these capabilities need to be across multiple services, multiple domains, and the entire lifecycle(TMF, 2019).

No doubt, this is the most ambitious goal that the networking industry has ever aimed at. It has been described as the “end-state” and“ultimate goal” of networking evolution. This is not just a vision on PPT, the networking industry already on the move toward the goal.

David Wang, Huawei’s Executive Director of the Board and President of Products & Solutions, said in his 2018 Ultra-Broadband Forum(UBBF) keynote speech. (David W. 2018):

“In a fully connected and intelligent era, autonomous driving is becoming a reality. Industries like automotive, aerospace, and manufacturing are modernizing and renewing themselves by introducing autonomous technologies. However, the telecom sector is facing a major structural problem: Networks are growing year by year, but OPEX is growing faster than revenue. What’s more, it takes 100 times more effort for telecom operators to maintain their networks than OTT players. Therefore, it’s imperative that telecom operators build autonomous driving networks.”

Juniper CEO Rami Rahim said in his keynote at the company’s virtual AI event: (CRN, 2020)

“The goal now is a self-driving network. The call to action is to embrace the change. We can all benefit from putting more time into higher-layer activities, like keeping distributors out of the business. The future, I truly believe, is about getting the network out of the way. It is time for the infrastructure to take a back seat to the self-driving network.”

Is This Vision Achievable?

If you asked me this question 15 years ago, my answer would be “no chance” as I could not imagine an autonomous driving vehicle was possible then. But now, the vision is not far-fetch anymore not only because of ML/AI technology rapid advancement but other key building blocks are made significant progress, just name a few key building blocks:

  • software-defined networking (SDN) control
  • industry-standard models and open APIs
  • Real-time analytics/telemetry
  • big data processing
  • cross-domain orchestration
  • programmable infrastructure
  • cloud-native virtualized network functions (VNF)
  • DevOps agile development process
  • everything-as-service design paradigm
  • intelligent process automation
  • edge computing
  • cloud infrastructure
  • programing paradigm suitable for building an autonomous system . i.e., teleo-reactive programs, which is a set of reactive rules that continuously sense the environment and trigger actions whose continuous execution eventually leads the system to satisfy a goal. (Nils Nilsson, 1996)
  • open-source solutions
