How does the WANScaler Handle Different Header Types Common in Today's Network Environments?

Q: How does the WANScaler handle the following header types, which are common in today’s network environments?

802.1Q
1Q in 1Q (802.1Q tagging)
Multiprotocol Label Switching (MPLS) (MPLS header)
MPLS-VPN (MPLS header tagging)
IP Security (IPSec) (Encapsulating Security Payload (ESP)/Authentication Header (AH) header)

A: The WANScaler recognizes and preserves 802.Q tagging. Other header types are recognized but are not accelerated. They are sent through unaltered.
