摘要： A method and system for measuring a convergence time of a network. Test traffic including a plurality of packet groups may be transmitted and received via the network. The network may be instructed to redirect packets belonging to a selected packet group from a first port of the network to a second port of the network. A first test port unit coupled to the first port may determine an arrival rate for the selected packet group and store a below threshold timestamp when the arrival rate first falls below a predetermined threshold rate. A second test port unit coupled to the second port may determine an arrival rate for the selected packet group and store an above threshold timestamp when the arrival rate first equals or exceeds the predetermined threshold rate. The convergence time may be determined based on the below threshold timestamp and the above threshold timestamp.

摘要： Methods, traffic receivers, and computer readable storage media for testing network connections are disclosed. A traffic receiver coupled to a network under test may receive a packet. A packet group identification number (PGID and a sequence number (SN) may be extracted from the received packet. Data associated with the PGID may be retrieved from a memory, the data including a next expected sequence number (NESN), a start of run (SOR), a number of in-order packets (NIO) and a number of duplicate packets (NDP). When SN is equal to NESN, NESN and NIO may be incremented. When SN is less than NESN and SN is greater than or equal to SOR, NDP may be incremented. When SN is greater than NESN, SOR may be set to SN, NESN may be set to SN plus one, and NIO maybe incremented. Updated data may be stored in the memory.
