- Emerging Networking Technologies
Having fast, reliable, and secure Internet is essential to operational success. The need for increased speed in data centers and cloud services speeds is driven by many things in the continued growth of hyperscale networks from players like Google, Amazon and Facebook, but also the more distributed and mobile workloads modern networks support.
Today. Networks are undergoing transitions. Software defined networking (SDN), Network Function Virtualization (NFV) and 5G are all technology evolution which are applying pressure to existing service provider networks and causing them to adapt in multiple ways. Similarly, a transition is occurring both inside and outside the data center. Where the data and the data centers are located are becoming increasingly important. Data centers with modern infrastructure have the technology to capture these transitions.
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 Beyond
Wi-Fi 6 and Beyond refers to the latest generation of Wi-Fi technology, also known as 802.11ax, which offers significantly faster speeds, improved efficiency, and better capacity for handling multiple devices compared to older Wi-Fi standards, while Beyond indicates the continued development of even newer Wi-Fi technologies that will further enhance connectivity capabilities beyond what Wi-Fi 6 currently provides.
This could include features like utilizing the 6GHz band (Wi-Fi 6E) and potentially even faster speeds with future iterations like Wi-Fi 7.
Key characteristics about Wi-Fi 6:
- Faster speeds: Delivers significantly faster data transfer rates compared to previous Wi-Fi standards.
- Improved efficiency: Utilizes technologies like OFDMA (Orthogonal Frequency Division Multiple Access) to efficiently handle multiple devices simultaneously, reducing latency and congestion in crowded networks.
- Enhanced capacity: Allows more devices to connect to a single network without noticeable performance degradation.
- Better battery life for devices: Features power-saving mechanisms to extend battery life on connected devices.
- Wi-Fi 6E: An extension of Wi-Fi 6 that opens up access to the 6GHz frequency band, providing additional spectrum for even better performance.
- Enhanced speed and efficiency: Multiple devices can share the same channel simultaneously, increasing network efficiency and reducing latency. WiFi 6 also uses 1024 quadrature amplitude modulation (1024-QAM) to increase throughput for emerging use cases. These improvements ensure faster and more reliable connections.
- The Future of Wireless 5G and Beyond
5G and Beyond refers to the future generations of wireless communication technology that will succeed the current 5G networks, aiming to provide even faster speeds, lower latency, and greater capacity, enabling new applications and experiences that require high-quality, real-time data transfer across a massive number of connected devices, essentially paving the way for a more interconnected and immersive digital world; often referred to as 6G in discussions about the next major leap in wireless technology.
6G is expected to emerge around 2030 and will offer faster speeds, lower latency, and greater capacity than 5G. But 6G is more than just “faster 5G” — it will enable entirely new technologies and services that 5G can’t fully support.
Key aspects of 5G and Beyond:
- Higher data rates: Potentially significantly faster speeds compared to current 5G networks.

- Multi-Cloud Architecture
A Multi-Cloud Architecture refers to a cloud computing strategy where an organization utilizes services from multiple cloud providers simultaneously, allowing them to leverage the best features and capabilities of each platform to optimize workloads, reduce vendor lock-in, and enhance flexibility by distributing applications across different cloud environments.
A multicloud environment allows your cloud environments to be private, public, or a combination of both.
Key characteristics about Multi-Cloud Architecture:
- Multiple providers: Unlike a single-cloud setup, a multi-cloud architecture involves using services from different cloud providers like AWS, Microsoft Azure, and Google Cloud Platform.
- Optimized workloads: Businesses can choose the most suitable cloud service for each specific application based on factors like cost, performance, and regional availability.
- Reduced vendor lock-in: By not relying solely on one provider, companies can avoid being tied to a single vendor's pricing and features, allowing them to switch providers if needed.
- Increased resiliency: Distributing workloads across multiple clouds can improve system availability and redundancy, mitigating the impact of potential outages from a single provider.
- Management complexity: A significant challenge of multi-cloud is managing multiple cloud environments with different APIs and interfaces, requiring dedicated tools and expertise.
- Hyperconvergence and Hyperconverged Platforms
Hyperconvergence refers to an IT architecture where computing, storage, and networking capabilities are combined into a single, unified system, essentially merging all these functions into one platform, significantly reducing data center complexity and enhancing scalability.
A hyperconverged platform is a specific implementation of this architecture, typically utilizing software-defined storage, a hypervisor for virtualized computing, and virtualized networking, all managed as a single unit.
Key characteristics about hyperconvergence and hyperconverged platforms:
- Unified system: Unlike traditional infrastructure where each component (compute, storage, network) is managed separately, a hyperconverged platform integrates them all within a single system, simplifying management.
- Software-defined: Hyperconverged platforms rely heavily on software-defined technologies, meaning the infrastructure is managed and defined through software rather than physical hardware configurations.
- Scalability: A key advantage of hyperconvergence is the ability to easily scale by adding new nodes to the cluster, allowing for flexible capacity expansion as needed.
Hyperconverged platforms consist of three software components:
- Hypervisor: A software layer that enables the virtualization of computing resources, allowing multiple virtual machines to run on a single physical server.
- Software-defined storage: A software-based approach to managing storage that abstracts the underlying hardware, enabling pooled storage across multiple servers.
- Virtualized networking: Software-based network management that allows for flexible network configuration and resource allocation.
Benefits of hyperconverged platforms:
- Reduced complexity: By integrating components into a single system, management overhead is significantly reduced.
- Simplified deployment: Easier to set up and deploy new infrastructure compared to traditional, multi-component systems.
- Cost efficiency: Potentially lower capital expenditure by utilizing shared resources across the cluster.
- Agility and flexibility: Enables rapid scaling to meet changing business needs.
