What is class of service in networking?
Class of Service (CoS) is a way of managing traffic in a network by grouping similar types of traffic — such as email, streaming video, voice over IP and large document file transfer — together and treating each type as a class with its own level of network service priority.
What is class of service in QoS?
Class of Service (CoS) or Quality of Service (QoS) is a way to manage multiple traffic profiles over a network by giving certain types of traffic priority over others. For example you can give Voice traffic priority over email or http traffic.
What is set when using CoS to mark an Ethernet frame?
The frames leaving the IP phone toward the workgroup (access) switch have the voice VLAN number in the VLAN ID field, and their priority (CoS) field is usually set to 5 (decimal), which is equal to 101 binary, interpreted as critical or voice bearer.
