Adaptive transport interoperability
Adaptive transport is a data transport mechanism for XenApp and XenDesktop. It is faster, can scale, improves application interactivity, and is more interactive on challenging long-haul WAN and internet connections. Adaptive transport maintains high server scalability and efficient use of bandwidth. By using adaptive transport, ICA virtual channels automatically respond to changing network conditions. They intelligently switch the underlying protocol between the NetScaler protocol called Enlightened Data Transport (EDT) and TCP to deliver the best performance. By default, adaptive transport is enabled, and EDT is used when possible, with fallback to TCP.
NetScaler SD-WAN WANOP offers cross-session tokenized compression (data deduplication), including URL-based video caching. It provides significant bandwidth reduction if two or more people at the office location watch the same client-fetched video, or transfer or print significant portions of the same file or document. Furthermore, by running the processes for ICA data reduction and print job compression on the branch office appliance, WANOP offers VDA server CPU offload and enables higher XenApp and XenDesktop server scalability.
When TCP is used as the data transport protocol, NetScaler SD-WAN WANOP supports the optimization as described above. When using NetScaler SD-WAN WANOP on network connections, choose TCP and disable EDT. By using TCP flow control and congestion control, NetScaler SD-WAN WANOP ensures the equivalent interactivity to EDT at high latency and moderate packet loss.
