A Quality of Service (QoS) policy must be implemented to provide preferred treatment for Command and Control (C2) real-time services and control plane traffic.
An XCCDF Rule
Description
Different applications have unique requirements and toleration levels for delay, jitter, packet loss, and availability. To manage the multitude of applications and services, a network requires a Quality of Service (QoS) framework to differentiate traffic and provide a method to manage network congestion. The Differentiated Services Model (DiffServ) is based on per-hop behavior by categorizing traffic into different classes and enabling each node to enforce a forwarding treatment to each packet as dictated by a service policy. Packet markings such as IP Precedence and its successor, Differentiated Services Code Points (DSCP), were defined along with specific per-hop behaviors for key traffic types to enable a scalable QoS solution. DiffServ QoS categorizes network traffic, prioritizes it according to its relative importance, and provides priority treatment based on the classification. It is imperative that end-to-end QoS is implemented to guarantee the required bandwidth for control plane traffic and C2 real-time services during periods of congestion within the JIE WAN IP network.
