Oversubscription Monitor

A system for oversubscription monitoring, comprising:

• an oversubscription buffer of a network component that buffers received data for processing;
• and
• an oversubscription monitor that:
• accumulates an amount of data that arrives at the network component over an epoch of time;
• determines whether the network component is operating in an oversubscribed region of operation based on a core processing rate of the network component;
• measures at least one quality of service metric of the network component;
• and
• generates a network operation display object that includes a representation of the at least one quality of service metric of the network component and identifies whether the network component operated in the oversubscribed region over the epoch of time.

A method of oversubscription monitoring, comprising:

• accumulating an amount of data that arrives at a network component and calculating a core processing rate at which data can be processed by the network component over an epoch of time;
• when the network component is operating in an oversubscribed region of operation, measuring at least one quality of service metric of the network component;
• and
• generating a network operation display object that identifies whether the network component operated in the oversubscribed region over at least one epoch of time.
