Abstract
A method of collecting consistent flow statistics through multiple congestion points within a multi-service switch/router is enabled by computing a payload length of each traffic unit received from a fabric of the switch/router. A PHY-level header containing the payload length, a class of service and a service ID is appended to the switch-internal encapsulated payload. Information associated with the PHY-level header is used at physical level congestion points to collect consistent flow statistics.
