Vasona Networks announced Version 2.1 of the company’s flagship Vasona SmartAIR, which builds on dynamic rate control with feedback (DRCF), adding Mobile Packet Assurance. This new feature enhances application performance when data packets are lost in the network not only as a result of bandwidth congestion, but also from weak signal strength or other performance-impacting events. Mobile Packet Assurance leverages Vasona Networks’ ability to take real-time action based on intelligence about all traffic in individual cells at any moment.
Based on its visibility of mobile data traffic globally, Vasona Networks estimates that when a typical high-quality video is streamed, packets are dropped every 5-10 seconds, hurting the viewing experience. Other types of traffic, such as mobile browsing or gaming, also suffer when packets are dropped, becoming slow or stalling completely. This degrades application performance, and contributes to network congestion and disruption of the mobile experience. Vasona Networks is positioned to address this common phenomenon as the network edge-based SmartAIR can assess and act on packet losses more quickly than devices in the mobile network core or those serving the data via the Internet.
“When a mobile operator can get out in front of packet loss problems and resend lost data more quickly, less packets have to be resent and the subscriber experience is improved,” says John Reister, VP of Marketing and Product, Vasona Networks. “Vasona Networks is raising the bar for speed of overcoming data loss based on current network conditions, resending lost packets the moment that cells can accommodate them.”
Alternative approaches are farther from the point of packet loss, and lack insight into what is happening on a cell-by-cell basis in real-time at the application level. This leads to longer detection delays and slower responses to problems, leaving users with more ‘spinning hourglass’ experiences. SmartAIR combines Mobile Packet Assurance with Vasona Networks’ DRCF functionality that monitors each cell and maintains a real-time congestion state for all flows. As a result, Vasona can avoid making a bad situation worse with constant resending of lost packets to an over-crowded cell that is momentarily incapable of handling the barrage of additional traffic. It also ensures that flows continue at the highest bitrate that the network can support, improving utilization at all times.
Version 2.1 of SmartAIR will be released mid-summer, with Mobile Packet Assurance as an added feature.
