Software defined network access for endpoint
Multiple types of lines are made simultaneously available, including a Wi-Fi link, a cell link and a wired link. A list of running cloud applications is identified by monitoring A quality of each available link for each running cloud application is periodically tested, including measurements of latency, jitter and packet loss. A first link is selected for a first application and a second link is selected for a second application. Data packets related to the first application are transmitted over a first link and data packets related to the second application over the second link.
