About WAN optimization on the Velocity physical appliance

The Velocity Appliance includes wide-area network (WAN) optimization technology to improve outbound network traffic to remote locations and/or slower networks. WAN optimization operates on individual TCP connections. The appliance evaluates each outbound network connection to determine whether the performance can be improved.

You can enable or disable WAN optimization for individual network interfaces and network interface port bonds from the Velocity shell menu.

WAN optimization can provide the following benefits:

• Improved network performance with minimal dependency on the outbound network traffic.

  Networks that have latency greater than 20 milliseconds and packet loss rates greater than 0.01% (1 in 10,0000) can greatly benefit from enabling this feature.

• Improved network performance of optimized ingests.

• Improved network performance of restores to remote hosts.

• Imposes no network overhead.

  WAN optimization is non-intrusive, as it does not impose any network overhead in situations where the overall network data transfers are high. In some scenarios, when the overall network data transfer is high, the connection speed may not be optimized despite this feature being enabled.
