Quality of service 编辑

The network between office locations and the data center or cloud must transport a multitude of applications and data, including high quality video or real-time voice. Bandwidth sensitive applications stretch the network’s capabilities and resources. Citrix SD-WAN provides guaranteed, secure, measurable, and predictable network services. This is achieved by managing the delay, jitter, bandwidth, and packet loss on the network.

The Citrix SD-WAN solution includes a sophisticated application Quality-of-Service (QoS) engine that accesses the application traffic and prioritizes critical applications. It also understands the requirements for 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.
