| Zusammenfassung: | A hierarchical multi-rate multi-precedence policer is disclosed. The policer discards packets based on assigned precedence levels. When traffic exceeds an available service rate, the policer drops packets of lower precedence levels to make room for packets of higher precedence levels. In certain implementations, the policer also guarantees bandwidth to each level, thus preventing complete loss of lower precedence traffic when there is a large amount of higher precedence traffic. |
