Question
manages different types of network traffic by classes.
Solution
This statement seems to be referring to Quality of Service (QoS). QoS is a technology that manages different types of network traffic by classes to enhance user experiences. Here are the steps it follows:
-
Identification: The first step in managing network traffic is identifying the different types of traffic. This could be email, VoIP, video, etc. Each type of traffic is then assigned to a specific class.
-
Classification: After identifying, the traffic is then classified into different classes. Each class represents a type of service. For example, VoIP might be one class, video another, and so on.
-
Policing: This step involves monitoring the traffic in each class. If a class is using more than its allocated bandwidth, the excess packets can be dropped or marked for later dropping.
-
Queuing: In this step, packets are stored in queues while they wait to be processed. Different classes can have different queue lengths, depending on their priority.
-
Scheduling: This is the final step where packets are sent from the queues to their destinations. The scheduling can be done based on priority, with higher priority classes being sent first.
By managing network traffic in this way, QoS ensures that all types of traffic get the necessary bandwidth and reduces the chances of network congestion.
