Claim:
1. A method for storing data associated with packet related metrics, the method comprising: generating a test packet including a port tuple sequence number (PTSN), wherein the PTSN is generated using port or path awareness information and indicates a position of the test packet within a sequence of packets associated with a same port tuple, wherein the sequence of packets includes packets from different flows, wherein the port tuple indicates an ingress port and an egress port that the test packet traverses at a device under test (DUT); storing the PTSN in an entry of a data structure, wherein the entry is indexed by the port tuple; sending, to the ingress port of the DUT, the test packet; receiving, from the egress port of the DUT, the test packet; analyzing, using information in the test packet and information stored in the data structure, the test packet, wherein analyzing the test packet includes identifying, using the port tuple associated with the test packet, the entry associated with the test packet and determining, using a PTSN stored in the data structure entry and the PTSN in the test packet, whether the test packet is an expected packet in the sequence of packets associated with the same port tuple; and generating one or more packet related metrics using the analyzing.
