Network Function Virtualization (NFV) is a new network architecture concept that uses IT virtualization technologies to decouple network functions, such as router, firewall, network address transition (NAT), and domain name service (DNS), from proprietary hardware appliances so that they can run as software on general purpose network platform. NFV aims to help telecom service providers obtain operation agility, OPEX efficiency and scale-on-demand network services.
Practical implementations of Lanner's technology in a range of environments and applications.
The increasing number of terrorist attacks to public transits has rapidly triggered the awareness of passenger safety. Public transportation like buses and trains in major cities became victimized for bombing. Mass transit operators are urging for a real-time mobile surveillance system to capture what could have been missed throughout the moving buses or subway system
SD-WAN is one of the most applied enterprise networking models among SDN applications. According to IHS market research, there will be approximately 45% of enterprises in North America to adopt SD-WAN in the next two years. The era of “software-defined everything” is happening in real-time and SD-WAN is already a booming sector.
Nowadays, small and medium enterprises are relying more and more on smart cloud services in order to stay connected anytime and anywhere. Indeed, cloud-based service solutions provide SMEs the flexibility and scalability for connections among their branches and client devices, at a lower investment in physical hardware. However, while enjoying the convenience and flexibility of cloud service solutions, the SMB communication networks are also exposed to cyber threats and are sometimes the victims to cyber attacks as well.
Since the cyber attack of Ukraine’s power grids in December, 2015, it is clear that traditional ICS, SCADA and off-the-shelf operating systems in substation present imminent vulnerabilities for cyber attack. As the OT networks in critical infrastructures and IT-based control layer devices are more and more interconnected, there have been more loopholes exposed to cyber intruders. Since the energy infrastructures are highly critical to the economic well-beings of the societies, a successfully penetrated attack would cause devastating effects to the enterprises, the government and the people. Therefore, it is necessary to implement an industrial-grade network gateway to secure the industrial communication networks and protocols as most cyber attacks come from this channel.
