12 WISPAPALOOZA SHOW I OCTOBER 9 – 12, 2023 www.bekabusinessmedia.com DAY 1 L Z OO 2023 Nielsen’s Law of Internet Bandwidth states that a high-end user’s connection speed grows by 50 percent per year. In looking at data from 1983 to 2023, it’s remarkable how closely the actual data fits the annualized growth stated by this law. Even with minor yearly variations, Nielsen’s Law of Internet Bandwidth has held true throughout a 40-year period. What does this mean for broadband network planning? It means a greater emphasis on network scalability, flexibility and agility. Software-based (or virtual) networks are designed for greater scalability and flexibility. This makes them ideal to deliver future-proof bandwidth speeds and capacities. And when WISPs begin to virtualize their networks, one of the first network functions they look to virtualize are broadband network gateways (BNGs). Virtual BNGs aggregate traffic from many subscribers and route it to the network of the service provider, performing subscriber management functions such as authentication, authorization and accounting of subscriber sessions. Once connected, a subscriber can access the broadband services delivered by their provider. vBNGs play a crucial role in ensuring optimal network performance. They act as a bridge between the service provider’s network and the subscriber’s devices, facilitating seamless connectivity and delivering high-speed internet services. The performance of vBNGs directly impacts overall network efficiency and the end-user experience. A high-performance vBNG can ensure lowlatency and high-speed internet services. On the other hand, poor performance can lead to network congestion, service degradation and dissatisfied customers. One key aspect of vBNG’s role in network performance is its ability to manage subscriber sessions efficiently. With an increasing number of connected devices and the growing demand for bandwidthintensive applications, vBNG plays a critical role in ensuring smooth and uninterrupted connectivity for end-users. By establishing and managing sessions between subscriber devices and the network, vBNG enables WISPs to allocate resources effectively and to prioritize traffic based on predefined policies. Given the importance of high-performing vBNGs, Intel and netElastic are working together to raise the bar on vBNG performance. In recent tests conducted by Intel, netElastic vBNG reached one terabit of throughput on a 2 RU server powered by 4th Gen Intel Xeon Scalable processors. This is a new level of performance for vBNGs. While not all WISPs may need one terabit of throughput today, given Nielsen’s Law of Internet Bandwidth, the bandwidth demands of tomorrow may require all that capacity. Intel’s recent tests prove that at these terabit performance levels, netElastic vBNG should be considered when maximum performance and scalability are needed. m To learn more, visit netElastic at booth 629 on the show floor. netElastic vBNG Helps WISPs Achieve Terabit Speeds
