What is advanced layer 4 stateful replay?
Traffic replay is an effective way to emulate the real-world network conditions to your device under test (DUT) since all the traffic content, packet sizes, inter-packet gap, packet pattern, and burstiness are a replay of reality.
Xena solution offers layer 4 replay
Xena’s Advanced Layer 4 Replay (XAR) solution is a highly scalable solution that provides stateful Layer 4 replay based on payload data from pcap files, and preserves correlation information across TCP connections for true emulation.
Reveal true object behaviour
XAR pcap parsing allows multiple TCP connections in one pcap, which greatly increases test efficiency and flexibility.
