Introduction Smartbyte is a client installed software application that focuses on network traffic optimization from a client system point-of-view. It aims to prioritize critical applications over non-critical applications in terms of bandwidth and QoS. Without an application like Smartbyte, bandwidth is equally divided among all the applications that access Internet.

Dell-on-Dell advantage When a SmartBytePro enabled machine starts a Priority 1 application or a priority 2 application, it will send out an encrypted, broadcast message indicating that a high priority application needs bandwidth. It will send out this message once every N seconds while the high priority application is actively sending/receiving traffic. All other SmartBytePro systems on the same LAN will receive this message and lower the maximum bandwidth used for traffic shaping by K mbps.

There are various scenarios in which Smartbyte helps in regulating bandwidth and some scenarios where Smartbyte is not helpful. Below table summarizes those scenarios and right column indicates whether Smartbyte is helpful in that scenario.
