For Carrier Ethernet, why is tagging packets alone not adequate for bandwidth management?

Tagging packets alone is not sufficient for effective bandwidth management because common carriers handle an immense volume of data, often processing trillions of packets per day. While tagging provides a mechanism to identify and classify traffic types within a network, it does not inherently provide the granular control required to manage bandwidth allocation dynamically. Bandwidth management involves understanding traffic patterns, monitoring usage, and making real-time adjustments to ensure that network resources are allocated efficiently, which is necessary given the scale at which these carriers operate.

Tagging can help in identifying the type of traffic but does not equate to the ability to manage the bandwidth according to that traffic's requirements. This highlights the need for more comprehensive mechanisms beyond just packet tagging to ensure effective bandwidth utilization, especially in high-demand environments.
