=== Live analysis === | |||
In live analysis mode, the packets are either gathered from the local device and a configured remote Allegro Network Multimeter, or from two different sources on the same local devices (different interfaces, different VLAN tags, or similar parameters available through virtual link group configuration). | |||
=== PCAP analysis === | |||
In PCAP mode, two PCAP files are processed the matching packets are used to determine the delay and possible loss between both files. For best results, the file should be recorded on the same device (by running two captures simultaneously from different sources), or from two devices with good time synchronization. | |||
