Safeguards IoT devices using a zero-trust network Helps in complying with the cybersecurity framework of the National Institute of Standards and Technology (NIST). Ways SD-WAN Can Help Businesses Boost their Bottom Line Boosts Security Digital transformation is a double-edged sword. It can increase consumer satisfaction and market reach, but can pose security threats. According to the U.S. State of Cybercrime study, 41% of respondents stated more cybersecurity occurrences in 2017. The good news is that many SD-WAN solutions provide built-in security. Most SD-WAN systems only offer basic firewall and VPN functionalities, requiring IT teams to add security to elastic and dynamic SD-WAN connections after the fact. SD-WAN solutions with NGFW, IPS, encryption, AV, and sandboxing can avoid data loss, downtime, regulatory violations, and legal liability. Enables Cloud Usage Cloud services are rapidly being used by businesses. The great news is that SD-WAN enables direct cloud access at the remote branch, removing backhauling traffic – which routes all cloud and branch office traffic through the data center – allowing workers to directly access cloud applications irrespective of location without burdening the core network with additional traffic to manage and secure. Furthermore, SD-WAN enhances cloud application performance by prioritizing vital business apps and allowing branches to interact directly with the Internet. Reduces Costs As businesses deploy a growing number of cloud-based services, the volume of data traveling across a WAN rises dramatically, driving up operational expenses. SD-WAN, thankfully, can minimize this cost by utilizing low-cost local Internet connectivity, offering direct cloud access, and lowering traffic via the backbone WAN. According to an IDC poll (prediction), over a quarter of survey respondents anticipate SD-WAN cost reductions of up to 39%, with the other two-thirds anticipating more modest savings of 5–19%. Improves performance Data transfer over a network isn't created equal. Fortunately, SD-WAN can be set up to prioritize business-critical traffic and real-time services such as Voice over Internet Protocol (VoIP) and then successfully guide it over the most efficient path. IT teams can help decrease packet loss and latency concerns by supporting important applications over dependable, high-performance connections, increasing employee productivity and morale. This is business-impacting performance. Closing Note Indeed, SD-WAN evolved and flourished in the data center over the first few years of development. However, the time has arrived to take it seriously as a tool for managing your wide area network. There are currently several vendors on the market, as well as several mature solutions to choose from. More significantly, the business cases for SD-WAN are expanding on a daily basis.

What is 5G SA? 2.1 Characteristics of SA Architecture 2.2 Benefits of SA Architecture 3. What is 5G NSA? 3.1 Characteristics of NSA Architecture 3.2 Benefits of NSA Architecture 4. Factors to Consider When Choosing Between SA and NSA 4.1 Cost Implications of Each Architecture 4.2 Future Implications of Each Architecture 5. Conclusion 1. Introduction to 5G Network Architectures Widespread implementation of 5G is transforming how businesses across verticals operate, providing enhanced speed, low latency, and massive connectivity. The advancements in 5G system architecture enable new use cases, from autonomous vehicles to smart cities. There are currently two types of 5G network architecture, namely 5G standalone (5G SA) and 5G non-standalone (5G NSA). These two architectures differ in how they connect to the existing 4G infrastructure, the type of equipment required, and the level of network independence. Therefore, understanding the difference between SA and NSA is crucial for companies and organizations implementing 5G architecture. 2. What is 5G SA? 5G SA architecture is an entirely new technology that uses 5G core network architecture, independent of the current 4G LTE network. It has various use cases, such as combining 5G with AI and edge use cases. 2.1 Characteristics of SA Architecture Independent Network: All components of the architecture, including the 5G core architecture, radio access network, and user equipment, are not reliant on any 4G technology. High Performance: 5G SA architecture is optimized for high performance and low latency, enabling fast data transfer rates and near-instantaneous response times. Distributed Architecture: This allows efficient resource allocation and dynamic management of network resources. End-to-End Encryption: It provides end-to-end encryption, which ensures that data is secure and protected from unauthorized access. Higher Cost: 5G SA architecture is more expensive to implement than NSA architecture due to the need for a fully independent 5G network infrastructure. 2.2 Benefits of SA Architecture Low Latency: Applications of 5G that require real-time processing are only possible with SA architecture. Customization: As SA does not depend on existing network architecture, it can be tailored to company requirements. It also enables network slicing for 5G enterprise private network use cases. Security: End-to-end encryptions ensure a more secure network, and 5G network slicing keeps various access levels separate. Scalability: 5G architecture is designed to be highly scalable and handle large volumes of data and devices. Future-proofing: SA architecture will be able to support upcoming 5G features and capabilities by design. 3. What is 5G NSA? 5G NSA provides a transition into 'true' 5G architecture by incorporating 4G network infrastructure for deployment. 3.1 Characteristics of NSA Architecture Non-Independent Network: 5G NSA architecture is designed to leverage the existing 4G infrastructure to deliver 5G services. Transition to SA: NSA offers lower latencies and faster speeds than 4G LTE without deploying 5G architecture.

The promise of Open vRAN is to give back to mobile operators some form of control over their networks. The “open” refers to the opening of RAN interfaces. It is critical because it gives operators the possibility to buy the radio unit and the baseband unit from different vendors, rather than having to buy an integrated system, and therefore helps them diversify their suppliers and reduce their dependence on traditional vendors. The “v” refers to virtual. Virtualization is about disaggregating hardware and software and enabling the use of commercial off-the-shelf servers, instead of the usual purpose-built hardware, to run network functions in order to increase flexibility and reduce costs. Across Asia-Pacific, the announcements and activities from operators including Airtel, Axiata, NTT Docomo, Rakuten Mobile, Smartfren and Telkomsel indicate a growing appetite for open and virtualized radio access networks. In countries like India, Indonesia, Malaysia and Thailand, open RAN can for example help to address the challenges of remote connectivity and to deploy a network in places where it has been traditionally difficult to achieve a satisfactory return on investment.
