2. Modern Computer Network Technologies
Abstract
Modern network technologies provide the basic infrastructure for information and communication systems in
the hospital today. The goal to build up a universal network infrastructure which meets the broadly varied
requirements. Analysis of data communication in the hospital and the evaluation of established network
technologies, as well as new developments, leads to the switching concept as the suitable solution. Two
technologies play the major role in building enterprise networks: the Ethernet family, based on frame switching,
and ATM, based on cell switching. Orientation on established standards is the key to free system choice and
grants interoperability between systems from different manufacturers. However, the network design must meet
the application and system architecture of the information technology in order to achieve successful mapping of
the involved communication profiles. This means scaling of the bandwidth as needed, suitable segmenting of
the network and resilient links. In a further step, policy-based networking takes advantages of prioritizing
critical applications and therefore reduces interdependencies across the network.
Growing Importance of AI in Networking
Networking technologies have been in existence for many decades with a singular purpose – the improvement
of data transmission and circulation through the use of information systems. While networking technology has
been around for decades, it is changing faster than ever due to a growing emphasis on AI technology.
As newer technologies such as AI driven networks are invented, computer networking has grown to include a
wide range of services, all created to provide enhanced connectivity and speedy communication.
As such, most companies have found themselves needing to upgrade their current networking infrastructure
solutions to accommodate the mobility of evolving trends. With this backdrop, here are the latest networking
technologies that are transforming the face of the networking industry.
Internet of Things
In this digital age, people rely more on the internet to find and share information. IoT is the technology that
enhances communication by connecting network devices and collecting data. Internet of Things is a critical tool
for businesses. AI has made it even more viable than ever.
AI is leading to massive changes in the IoT market. The number of IoT devices is projected to skyrocket from
10 billion to 64 billion between 2018 and 2025. Experts project that 40% of all IoT changes will be shaped by
AI.

3. 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.
In essence, IoT is providing a much-needed balance between the real world and virtual experiences.
Artificial Intelligence
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.
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.
5G
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.
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.
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 you leverage top networking technologies, we can guarantee that your company continues to have access
to the critical information you require to keep things running smoothly and efficiently.

4. Next-Generation Wireless Technology
Without a doubt, the biggest networking technology development of the 2020s is one that’s going to be all
around us very soon – the deployment of next-generation wireless networks. In the mobile networking arena,
it’s the 5G standard that’s going to rewrite the rules of what’s possible for technology on-the-go. It’s these new
cellular networks that are going to unleash the true potential of things like augmented reality and the IoT, as
well as bringing us closer to a world filled with “smart everything“.
Indoors, the wireless revolution’s going to be led by Wi-Fi 6, the soon-to-go-mainstream standard that’s making
its way into devices right now. It will not only triple the theoretical maximum throughput of its immediate
predecessor, but will deliver better indoor signal penetration and support greater device density. In a world
where every electrical device is gaining networking capabilities, the effects of Wi-Fi 6 can’t be overstated.
SD-WAN Becoming Common
Over the course of the last decade, cloud providers, SaaS and IaaS solutions, and mobile computing have come
to challenge the traditional notion of boundary-driven networking. In the past, corporate and other private
networks were animated by the concept of fenced-off access using firewalls and other location-centric controls.
Now, as business computing assets have started to spread to remote data centers and mobile systems, a new
concept has emerged – software-defined wide area networks (SD-WAN).
This new paradigm in networking makes it possible to use a variety of network interconnections to create a
private business LAN analog consisting of assets in the cloud, data centers, and branch offices that function like
a single, seamless system. More than anything, this is made possible by continued improvements in WAN link
bandwidth, which now allow geographically disbursed resources to move data at or near LAN speeds across
vast distances. As the 2020s wear on, SD-WAN will come to replace traditional hardware-based onsite
networking approaches.
Connecting the Future
Judging by these and other trends now reshaping the world of networking, the 2020s are going to see the
technology landscape in that field change significantly. Many of the longest-held concepts and traditional
infrastructures will be replaced with more modern ones that take the needs of next-generation connected devices
into account. In many ways, the idea of data networks themselves will be updated to reflect the new reality of
border-free, seamless connectivity that we have now come to expect.
There’s sure to be plenty of hurdles to overcome and obstacles to the remaking of networking technology as
we’ve known it, but one thing is clear: networking technology, which has remained mostly unchanged for much
of its history, is due for disruption on several fronts – and it’s coming in more ways than anyone is likely to be
able to foresee. It’s going to make it an interesting time to be a networking professional, and that part is certain.
