Abstract
Embodiments are directed towards improving the performance of network traffic management devices by optimizing the management of hot connection flows. A packet traffic management device ('PTMD') employs a data flow segment ('DFS') and control segment (“CS”). The CS performs high-level control functions and per-flow policy enforcement for connection flows maintained at the DFS, while the DFS performs statistics gathering, and per-packet policy enforcement, on connection flows maintained at the DFS. The DFS may include high-speed flow caches and other high-speed components. Making efficient use of the high speed flow cache capacity may be improved by maximizing the number of hot connection flows based on unique service and network traffic characteristics through adaptive feedback pattern learning together with administrator configurable service preferences that may have flow control data for most bandwidth hungry and desired hot services offloaded to the high-speed flow cache, at appropriate time.
