Roaming A Look Under The Hood
 What happens when a emulated client roams?
•
Each VeriWave test port supports a separate instance of each client
•
Roaming essentially deactivates one instance and activates another
 Realistic but repeatable roaming process
•
Controlled power & FER ramp up/down, probes before re-association, etc
WaveQoE Real-World Mix of Client Traffic

 Representative device and user
profiles for key wired & wireless

L2-L7 Stateful Behavior of Every Client
QoE test needs are fundamentally different from both
traditional packet blasting as well as transaction testing
 Each client or server maintains a full protocol stack from L2 – L7
•
MAC; TCP/IP; application layer protocols such as HTTP, FTP, SIP, MPEG-2, etc.
 Each client or server can support separate security, QoS, mobility contexts
•
Represent real users that exist and move around real networks
 Each client or server can exhibit different behavioral characteristics
•
VoIP phones, video servers, computers, RFID tags, scanners, etc. all behave differently
 LAN and wireless and TCP/IP QoS protocols are supported
•
802.1D (Ethernet), 802.11e (WLAN), DiffServ, IP TOS, etc.
 Comprehensive LAN security for both Ethernet and wireless
•
Full IEEE 802.1X protocol stack with complete EAP support (LEAP, EAP-PEAP, EAP-MSCHAPv2,
EAP-TLS, EAP-TTLS, etc.)
•
Line-rate / air-rate encryption to AES standards
