Blocking monitoring, message flow control in blocking network involves comparing packet, acknowledgement circulation time with defined time for no blocking or known degree of blocking

摘要

The method involves sending a packet into the network, recording a first time stamp on the basis of sending the packet and recording a second time stamp when an acknowledgement is received back via the network in response to the packet. The circulation time of the packet and acknowledgement is determined from the time stamps and used to assess the degree of blocking in the network by comparing it with a defined time for no blocking or form a known degree of blocking. Independent claims are also included for a system of monitoring blocking in a network, for a machine-readable program memory and for a processing system.
