Measurement of OSPF-MPLS-TE-FRR Line Transitions and Data Losses

—In this paper, when using Open Shortest Path First (OSPF) and Multi Protocol Lable Switching-Traffic Engineering (MPLS-TE) in Internet Protocol (IP) packet switching networks recover time was tested and compared and during that time amount of data lost in case of the link overload and failure. For the accuracy of measurements, two different traffic generators were used and the differences were compared. One of them is Simena device and the other one is a Hping3 program working with Linux platforms. Line transitions and data losses were measured seperately with Simena and Hping3, calculations were performed and results were compared
