2. “Modern Computer Network Technologies”
Technology has become one of the most important tools today in our daily life. Today in our
daily life we have the top of the best systems and components that make every device efficient
and smarter.
A network is a connection between different devices that share information and work in real time
in harmony with software and hardware technology. Especially networks are used to connect this
devices and computers to the internet.
the list of current trends in the field of (computer) networking is long. Some of modern computer
network technologies are listed below with short description:-
❖ 5G Technology
5G is the latest in mobile internet connectivity. It not only allows for greater speed, and
a higher number of connected devices, but network slicing as well.
Network slicing is the creation of subnetworks – by separating multiple virtual networks
operating on the same network infrastructure – to fulfill specific needs required by
different applications. 5G is also designed to improve connectivity among devices and
enhance data transmission.
This has the potential to transform business models and the network industry as we
know it.
Also related to this other network technologies are:- 5G-enabled Mobile IoT
Applications, Vehicle-to-Everything (V2X) Services, SDN and NFV for 5G Mobile
Networks.
❖ Artificial intelligence (AI) and machine learning (ML)
Analyzing data with machine learning (ML) algorithms and artificial intelligence (AI)
will become the common starting point for many technology. ML can make predictions
based on network data. And in the broader sense, AI can take intelligent action based on
those predictions.
Artificial intelligence (AI) and machine learning (ML) technologies will be critical in
solving many of today's complex network and business problems in real time. These
technologies apply to use cases ranging from smart cities, transportation, and
manufacturing to security and networking.
With AI, network systems are being developed to perform enhanced analytics and
automation. By mimicking human intelligence and analyzing data with inbuilt
algorithms, this technology is revolutionizing users’ networking experience.
AI will also employ cost-effectiveness in developing and maintaining networking
systems.
With AI monitoring the algorithms within the network, we will not only guarantee faster
access to applications and platforms in your business but also troubleshoot threats at
record speed.

3. The capabilities, business opportunities, and benefits of AI and ML are growing at a
seemingly exponential rate. At the same time, the security vulnerabilities, failure modes,
and potential for adverse business impacts are seeing similar growth.
❖ Augmented Reality and Virtual Reality:
Augmented reality (AR) and virtual reality (VR) technologies increasingly empower
mainstream applications and customer experiences. They have begun to make their leap
from nascent technologies to comprehensive solutions that enable and empower many
mainstream consumer and enterprise applications, customer experiences, and various
industry workflows.
❖ Cloud Computing:
Cloud networking, or cloud-based networking, gives users access to networking
resources through a centralized third-party provider operating inter-connected servers.
This involves connecting to a Wide Area Network (WAN) or other internet-based
technology, and helps to distribute content quickly and securely.
The Cloud will continue to help companies save both space and money. Businesses of
all types and sizes will continue to adopt Cloud services. The benefits of the Cloud are
numerous in modern world and include:
• Cost Reduction
• Efficiency
• Data Security
• Scalability
• Mobility
• Disaster Recovery
• Control
Similarly it also includes other technologies like:-
Infrastructure as a Service (IaaS),SD-based CC Networking, EVPN Use for CC
Networking, Mobile CC (MCC) in 5G.
❖ Cloud Repatriation:
Cloud repatriation or unclouding is a form of reverse-migration. It involves the transfer
of applications and certain workloads from the public cloud to on-premise infrastructure.
The technology is gaining popularity amongst businesses today and it’s not unsurprising,
giving its benefits. Not only does it offer more control to organizations, but private
clouds also enhances compliance, resources management, and help reduce the risks and
frequency of cyberthreats. The cost-saving measures of this trend are an added perk.
❖ DevOps:
DevOps is most closely tied to software development and IT. But now, networks are
becoming more software-driven. DevOps can be a powerful tool for managing them,
too.

4. It improves the relationship between network service designers and the engineers who
need to make the actual operational changes to the services. It also puts responsibility
for automating network operations straight into the hands of the engineers. These are the
people with the most knowledge and experience of the network.
❖ Digital Transformation:
Digital transformation is disrupting businesses in every industry by breaking down
barriers between people, businesses, and things. Organizations of all types, in every
industry, are experiencing digital transformation. And they share a theme: Create new
customer experiences, transform business models, and empower workforce innovation.
❖ Intent-Based Networking (IBN):
An intent-based network bridges the gap between business and IT. It captures business
intent and continuously aligns the end-to-end network with that intent. Intent can apply
to application service levels, security policies, compliance, operational processes, and
other business needs.
❖ Internet of Things (IoT):
A major technology shift is happening in our world, and it is centered on the Internet of
Things (IoT). In this digital age, people rely more on the internet to find and share
information. Internet of Things is a critical tool for businesses. IoT is the technology that
enhances communication by connecting network devices and collecting data.
The collected information helps organizations analyze and predict consumer behavior.
With this information, they can improve the quality of their products, resulting in higher
returns, more profits, and brand expansion.
IoT is about connecting the unconnected. Most objects in the world are not connected to
computer networks, but that paradigm is changing rapidly. Previously unconnected
objects all around us are acquiring the ability to communicate with other objects and with
people, resulting in new services and efficiencies in our daily lives.
Because of the far-reaching benefits IoT can deliver, some theorize that it will be as
transformative as the Industrial Revolution.
AI has made it even more viable than ever.
In essence, IoT is providing a much-needed balance between the real world and virtual
experiences.
There are also other modern technologies include IoT , such as: Industrial Internet of
Things (IIoT), Internet of Robotic Things (IoRT), Industrial of Vehicels (IoV).
❖ Edge Computing:
This is another networking technology that has the potential to improve operational
efficiency in businesses and organizations. Edge computing is a consumer-focused
technology that is used to optimize data collection and processing.

5. If utilized effectively, it can improve the performance of business platforms by reducing
traffic loads and eliminating latency for speedy data analysis and better security.
Once we leverage top networking technologies, it can guarantee that our company
continues to have access to the critical information we require to keep things running
smoothly and efficiently.
❖ Network Security/Data Security:
Network and data security are designed to protect the usability and integrity of our
network and data. This includes both hardware and software technologies. Effective
network security manages access to the network. It targets a variety of threats and stops
them from entering or spreading on your network.
❖ SD-WAN:
SD-WAN is a software-defined approach to managing WANs. This new approach to
network connectivity can lower operational costs and improve resource usage for
multisite deployments. With SD-WAN, network administrators can use bandwidth more
efficiently and can help ensure enhanced performance for critical applications without
sacrificing security or data privacy.
SD-WAN is a software-defined approach to managing the WAN.
Key advantages include:
Reducing costs with transport independence across MPLS, 4G/5G LTE, and other
connection types.
Improving application performance and increasing agility.
Optimizing user experience and efficiency for software-as-a-service (SaaS) and public-
cloud applications.
Simplifying operations with automation and cloud-based management.
Like SD-WAN there is also technologies like:- Software-Defined LAN (SD-LAN),
Software-Defined Data Center (SDDC)
❖ Software-Defined Networking (SDN):
SDN delivers speed and agility when you deploy new applications and business
services. Flexibility, policy, and programmability are the hallmarks of our SDN
solutionsProvision, manage, and program networks more rapidly with software-defined
networking. In this centralized approach to network management, the underlying
network infrastructure is abstracted from applications. SDN provides choice in
automation and programmability across data centers, campuses, and wide-area networks.
❖ Wi-Fi 6:
The next generation of the Wi-Fi standard is Wi-Fi 6, also known as 802.11ax, the latest
step in a journey of nonstop innovation. The standard builds on the strengths of 802.11ac

6. while adding efficiency, flexibility, and scalability that allow new and existing networks
increased speed and capacity with next-generation applications.
The Institute of Electrical and Electronics Engineers (IEEE) proposed the Wi-Fi 6
standard so it can couple the freedom and high speed of Gigabit Ethernet wireless with
the reliability and predictability found in licensed radio.
So at last it can be said that, In today’s digital world, networking technology is
everything. It’s what makes the internet possible & with these technologies our daily to
daily life is becoming more easier and connected.
