Future Computer Networking and The Internet

(Stanford University - Jaclyn Chen)

- The Role of The Network In Digital Transformation

Digital Transformation can be described as the changes associated with the application of digital technologies in all aspects of business and society. Today, Digital Transformation extends much further and far deeper into the organisation, crossing and intersecting with a great many more business functions, processes and boundaries. And with the increase in mobile connectivity, social media, cloud computing and big data analytics, organisations need new ways of dealing with the customer experience and market opportunities.

In technology, networking is connecting a system of computers to share information. The Internet is just that type of service. Technology is advancing everyday. Because networks operate behind the scenes in our homes and businesses, we usually don’t think about them unless something goes wrong. Yet computer network technology is continuing to develop in new and interesting ways.

In Today’s constantly evolving, on-demand world, the network still needs to scale for massive capacity growth, but it now also needs to be more agile and programmable to better respond and handle unpredictable traffic requirements associated with cloud connectivity and the proliferation of mobile devices.

As customers are now typically global, data workflows have become ever more complex and applications increasingly more sophisticated, the network infrastructure therefore has to prevent any disconnect throughout the organisation, especially in terms of access to data or operational processes across the business, or regional boundaries.


- Emerging Networking Technologies

Emerging networking technologies focus on research in the areas of Mobile 5G and Beyond, Wi-Fi 6 and Beyond, Information Centric Networking, Cloud and Edge Computing, Smart Grid Communications, Wireless Sensor Networks, and Localization with the goal of developing and applying measurement science techniques for their performance evaluation. Some of these techniques include Network Sampling and Measurement, Congestion Control Algorithms, Learning of Network Topology, Modeling and Estimation of Network Dynamics, and Network Robustness and Vulnerability.

Today’s networks are very complex and run a large set of network protocols where implementation bugs can be very costly when gone undetected. Emerging networking technologies also look at formal methods and ways to exploit runtime network verification techniques.


- Wi-Fi 6 and Beond

Wi-Fi 6, also called 802.11ax, is an upgrade on the current highest-speed Wi-Fi protocol in wide use, 802.11ac. Wi-Fi 6 brings a dramatic improvement in efficiency across all existing Wi-Fi bands, including older 2.4GHz frequencies. Wi-Fi 6 will also likely get new spectrum in the 6GHz band, further improving its speed. The biggest improvement that comes with Wi-Fi 6 is that it increases the density of devices that can co-exist in a single space, further increasing the speed of all devices when there is more than one.

Beyond 2019, mobile 5G will bring improved speed and battery life to smartphones, as well as the growth of fixed wireless for residences, competing with wired broadband for some communities. 5G fixed wireless will be a convenient option as a WAN connection for getting branch offices online. It may have the performance (high speed and low latency) to compete with wired connections.

5G’s wireless technology will also make it into corporate local-area networks: An extension of the licensed 5G spectrum into a new, lightly-licensed band, CBRS (Citizens Broadband Radio Service), will allow businesses to set up their own, completely private 5G data networks. For some IoT installations, this could be a compelling solution. Wi-Fi 6 and 5G will coexist as critical wireless technologies for the enterprise.
