The Root Cause: WAN Limitations

� Applications and video work well on LAN:

High bandwidth

Low latency

Reliability

Round Trip Time ~ 0mS

Client LAN Switch Server


� But not on WAN:

Low bandwidth

Application chattiness

High latency

Frequent packet loss

Round Trip Time ~ hundreds of milliseconds

WAN limitations cause poor application and video performance, and keep servers and storage in branch offices

Data Redundancy Elimination

TCP Optimization

App-Specific Acceleration

Video delivery optimization

Accelerates TCP performance over the WAN

Redundant data does not need to transit the WAN – reduces overall bandwidth usage

Optimizes application protocols, such as MAPI, CIFS, NFS, HTTP, Print – eliminates protocol inefficiencies

Streamlined video delivery ensures one copy of live streaming transits the WAN

� Core WAE acts as a Trusted Intermediary Node for SSL requests by client.

� Private Key and Server Certificate are stored on the Core WAE device.

� Core WAE participates in SSL Handshake to derive “session key”

� Distributes the “session key” securely in-band to the Edge WAE over the established connection between the Edge WAE and Core WAE.
