Quality of service, or QoS, is an essential aspect when mixing real-time and bulk traffic. Once you add big data applications, the challenge grows. There are a few strategies that can be used to protect real-time traffic in hybrid environments where end-to-end QoS may not be implemented. Let’s dive in.
Hybrid is a combination of an on-premise Cloud Desktop Service and remote cloud services provided by any cloud hosting provider. The on-premise systems support platforms delivered as an as-a-service model, while the vendor system could offer a variety of services, such as infrastructure, platform, data center, or software. With a hybrid cloud, some components of an application might be located on-premises or externally. An application with real-time communications between sites must be prioritized over non-real-time traffic.
You may have software service, such as VoIP, that offers real-time components. To voice control of your system service, you must connect the endpoints within the organization. Call control services have less critical timing constraints than the real-time streams located in the cloud provider’s infrastructure.
No QoS over the internet
With QoS, you can prioritize different types of traffic. This can be done by marking the packets with either a class-of-service (CoS) or Differentiated Services Code Point (DSCP) identifier. After the packets are marked, the network utilizes the embedded CoS/DSCP identifier to perform limiting and prioritizing. Prioritized packets are transferred before the rest. A QoS has four, eight, or twelve different classes.
