Method and apparatus for packet buffering measurement

摘要

A method, apparatus and computer program product for packet buffering measurement is presented. A plurality of packets are transmitted to a packet switching device. Packets are received from the packet switching device. A determination is made, with respect to a particular time, based on packets transmitted to the packet switching device and packets received from the packet switching device, regarding a number of packets being held in a memory of the packet switching device.

1. A computer-implemented method comprising:
transmitting a plurality of packets to a packet switching device; receiving packets from said packet switching device; and determining at a particular time, based on packets transmitted to said packet switching device and packets received from said packet switching device, a number of packets being held in a memory of said packet switching device, wherein said transmitting a plurality of packets to a packet switching device includes providing a transmit timestamp for each packet transmitted, wherein said receiving packets from said packet switching device further comprises recording said transmit time stamp for each packet received and recording a receive timestamp for each packet arriving at said packet switching device wherein determining from said transmit timestamps and said receive timestamps one of: a forwarding rate for packets through said packet switching device, a number of lost packets for said packet switching device, a latency for packets through said packet switching device.
