Quality of service

The network between the data center and branch offices transports a multitude of applications and data, such as high quality video or real-time voice. The network capabilities and resources are stretched by bandwidth sensitive applications. The SD-WAN network provides guaranteed, secure, measurable, and predictable services. This is achieved by managing the delay, jitter, bandwidth, and packet loss on the network.

NetScaler SD-WAN solution has a sophisticated application QoS engine that accesses the application traffic and prioritize it against other applications. It also understands the requirements for the WAN network quality, and picks a network path based on the quality characteristics in real time.

The topics in the following sections discuss QoS classes, IP rules, application QoS rules, and other components that are required to define application QoS.
