CoS Class of Service Definition: CoS (Class of Service) is a way to prioritize and differentiate types of network traffic by assigning different levels of service quality based on packet marking or tagging.
CoS (Class of Service) in cybersecurity refers to a method used in networking to prioritize different types of traffic based on the level of service they require. It is commonly employed in Quality of Service (QoS) mechanisms to ensure that critical data, such as voice or video traffic, receives priority over less essential data in a network environment. CoS helps in managing and controlling the flow of data across a network by assigning specific priorities to packets based on their specified class. This ensures that important and time-sensitive information is delivered efficiently and with minimal delay, enhancing the overall performance and user experience of the network.
