HNQueue

HNQueue component is intended for buffering and synchronized multithreaded packets processing. The basic element of the queue is the HNPacket object.

The queue consists of two categories of elements:

• Free - empty HNPacket objects, free for using in packets processing;
• Full - HNPacket objects, awaiting for processing.

So, the queue contains two synchronyzed lists, and while HNQueue works the HNPacket objects from one list are moved to another one:

Get_FullItem Get_FullItems Return_FreeItem Return_FreeItems Return_FullItem Return_FullItems Get_FreeItem Get_FreeItems

HNQueue component can interchange with HNAdapter component by using ReceiveQueue property. This way you can achieve the traffic processing with very high performance because HNAdapter component uses queue items directly, without additional copying of them.
