Abstract: A system and method are provided for monitoring network performance in a network controlled by a communication access method. The communication access method is modified to communicate with a network performance monitor so that the communication access method will monitor its internal processing for information units for a predetermined resource upon request of the network performance monitor. The communication access method time stamps each inbound and outbound information unit for the predetermined resource and sends formatted data regarding each information unit, including the time stamp data, to a predetermined exit from the communication access method. The network performance monitor obtains the formatted data from the performance exit and processes the formatted data to determine network performance in relation to the predetermined resource.
