What is the common usage of the MPLS EXP bits?
The MPLS EXP bits, also known as the Traffic Class field, are commonly used to carry Quality of Service (QoS) classification. This helps manage network traffic by assigning priority levels, ensuring that critical data can be transmitted with the necessary performance. This usage is standardized and widely implemented to facilitate efficient traffic management in MPLS networks.
The Traffic Class field was renamed from the Experimental (EXP) field in RFC 5462. It was always intended for carrying quality of service (QoS) information
