TCP Acceleration

TCP Acceleration
The TCP Acceleration Performance Enhancing Proxy (PEP) is an optional feature that can be enabled on the Wan Accelerator to significantly enhance performance when sending TCP traffic over suboptimal network conditions or to improve TCP performance of slow TCP stack implementations.

Note: The PEP TCP Accelerator is available in v.4.
Limitations of Standard TCP
Most applications such as Email, HTTP, FTP and [...]

Packet Loss Recovery


Modern TCP stacks have become more efficient at dealing with latency by adding TCP Window Scaling and Selective Acknowledgements. However TCP is still vulnerable to packet loss and this has a drastic impact on network performance. Some degree of packet loss is almost always present in every wide area network. At times it is due to link quality but at other [...]

Router Mode – Out of Path

Wanos runs in bridge mode by default. In some cases it might not be possible to place a simple bridge appliance in-line or in-path. In this scenario out of path can be used by configuring the wan optimizer in router mode or server mode. This mode needs to be manually configured.

When router mode is configured, only the physical wan0 interface [...]

Quick Start Guide:
By default Wanos runs in bridge or switch mode. In this back to back lab example, theoretically no configuration is required on the Wanos appliance to test optimization. In other words, it is plug and play, as long as the wan0 and lan0 are plugged into [...]
