Abstract
In shared media communication systems, such as an Ethernet network, certain quality of service guarantees, such as a bandwidth “reservation,” are negotiated between a source node, a destination node, and every intervening node that will facilitate the transport of a packet. A packet scheduler insures that a node operates in accordance with the previously negotiated resource guarantee. In order to test the performance of a packet scheduler, a capture of packets is started, and while the capture is proceeding, intermittent triggering packets are inserted into the capture. After terminating the capture, the extensible network monitoring software will analyze the packets and transfer interpretative control to extensible modules, such as a DLL, based on packet type. When a special triggering packet is encountered, the corresponding triggering DLL is called and will access a file defining the various packet flows of interest. Each packet will be analyzed until the next triggering packet is encountered and the performance statistics will be summarized on a per-flow basis using the extensible network monitoring software interface to display such statistics on a user interface.
