Viptela vEdge versus NetScaler SD-WAN
Criteria Viptela vEdge NetScaler SD-WAN NetScaler SD-WAN Advantage
Device-managed Device-managed approach provides faster failover and
Failover Methodology Routing table changes
Seamless to application operational simplicity.
Packet-based path selection is more bandwidth efficient
Path Selection By applicatlon flow By packet
and provides a better user experience
Path Measurement & Recovery NetScaler SD-WAN can react to brown out and black out
Sub-second to seconds Milliseconds
Speed issues in less than a second
Bandwidth bonding ensures efficient bandwidth usage,
Bandwidth Bonding No Yes
while vEdge must statically map to a WAN link
Dual-ended QoS is a requirement for reliable application
Dual-ended QoS No Yes
delivery over Internet-based connections
Assigns apps to links / no Applications are not symmetric, same as broadband. So
Unidirectional selection Yes
assymetric routing measurement and selection shouldn’t be symmetrical
NetScaler SD-WAN can ensure lossless deliver for VoIP or
Packet Duplication No Yes
other mission critical applications
With Enterprise Edition, NetScaler SD-WAN provides data
Data compression & Reduction No Yes
compression and de-duplication
With Enterprise Edition, NetScaler SD-WAN provides
Protocol Acceleration No Yes
protocol acceleration
Despite a similar level of configuration complexity,
Configuration complexity Simple Simple
NetScaler SD-WAN provides much more value
