Packet delay analysis in operational network

Based on the previous work carried out on experimental validation of theory on fundamental bounds in communication network by J Y Le Boudec and Patrick Thiran in the context of networked control systems, steps are taken to define an algorithm enabling to automatically associate a time constraint requirement with a priority level and a weighted value. More advanced optimization algorithms are also studied for the determination of the weights. A test bed scenario is created on existing automation system. End to end packet delay for different flows and Jitters for the periodic flow is calculated on master server using packet sniffer “Wireshark” while backlog and packet loss of the switch port using Switch Port Analysis (SPAN) and Packet Flow/ SNMP Results obtained are recorded and compared with that of analytical model of WRR for tuning to tighten the bounds.
