Optical Networks Virtualization and Slicing in the 5G era

April 9, 2018

Future 5G networks will support a wide range of services and use cases arising from different vertical industries (e.g., IoT, eHealth, Industry4.0, etc.). Each of these services / business cases impose their own set of requirements to the network infrastructure, in terms of security, latency, elasticity, resiliency, and bandwidth. To deal with these challenges, the NGMN proposed the concept of network slicing (NS). Briefly, a network slice instance is formed by a set of network functions, and the resources enabling the deployment of these functions, forming a complete instantiated logical network to meet certain network characteristics for a specific service.

The Right Approach to Zero Trust for IoT Devices

whitePaper | May 3, 2022

Networking and security teams have historically relied on protections at the network perimeter to secure the entire enterprise. The internal network was deemed trusted and secure. While everything outside was considered “dirty,” everything on the internal network was considered “clean,” and application traffic would flow unrestricted. However, recent and developing shifts in enterprise working models are having a far-reaching effect on the traditionally managed network perimeter for security. The following trends are making organizations reassess their approach to security:

Virtual software platform for the car

whitePaper | October 4, 2022

Virtualization technology is gaining acceptance in the automotive industry. It makes the development process of software systems more efficient, reduces development and BOM costs, and shortens time-to-market. Especially in the cockpit, manufacturers and their direct suppliers have now been using hypervisor-based systems for several years. This first step towards a new conception of solutions is now experiencing another paradigm shift: the use of open standards. It further enhances the advantages of virtualization. The fully virtualized guest operating systems can be flexibly deployed and reused across all hardware. Only then can the full potential of virtualization technology be fully exploited
