Abstract: Applications executed out of router memory may acquire additional bandwidth that is not being used by other applications, in order to speed up network traffic. Scavenging may occur up to a point where current congestion is detected, at which point any scavenged bandwidth is relinquished and the application returns to its prescribed limit. After current congestion is mitigated, scavenging may occur up to a limit below the point where congestion was detected. After a predetermined interval, additional scavenging may occur beyond this limit until a preset bandwidth limit is reached.
