Performance Test Scenario :
Benchmarking : Routing table

Last Update : December 2, 1999

This scenario verifies the performance characteristics of a network interconnecting device, when the target ROUTER is attached to the model network.

Then, this scenario determines about IP datagram size exclude the Ethernet header in this scenario.

• Subjects :

  Verification of router's performance about packet forwarding of ROUTER which has many entries in routing table

  Verification Points :

  - Frame loss rate

  Send a specific number of frames at a specific rate through the DUT to be tested and count the frames that are transmitted by the DUT.

  The frame loss rate at each point is calculated using the following equation:

  ( ( input_count - output_count ) * 100 ) / input_count

  - Throughput

  Send a specific number of frames at a specific rate through the DUT and then count the frames that are transmitted by the DUT.
  If the count of offered frames is equal to the count of received frames, the fewer frames are received than were transmitted, the rate of the offered stream is reduced and the test is rerun.
  The throughput is the fastest rate at which the count of test frames transmitted by the DUT is equal to the number of test frames sent to it by the test equipment.

• Detect Protocol :

  UDP

• Physical Network Configuration :

           HOST-2

• Test Machine :

• Applications :

  Performance is checked by using application program "tg".

• Performance Check :

Devices Under Test(DUT)

• Matrix :

After the trial from (1) to (10) has been finished, repeat the trial from (1) to (10) total 5 times.

• Reporting format :

  - Frame loss rate

  The X axis is the input frame rate as a percent of the theoretical rate for the media at the specific IP datagram size.
  The Y axis MUST be the percent loss at the particular input rate.

  The left end of the X axis and the bottom of the Y axis MUST be 0 percent.
  the right end of the X axis and the top of the Y axis MUST be 100 percent.

  Multiple lines on the graph MAY used to report the frame loss rate for different IP datagram sizes, protocols, and types of data streams.

  - Throughput

  the x coordinate is the IP datagram size.
  the y coordinate SHOULD be the frame rate.

  There SHOULD be one line showing the theoretical frame rate for the media at the various IP datagram sizes.
  The second line SHOULD be the plot of the test results.

• Appendix A :

  Maximum frame rates reference

Theoretical maximum pps rates for Ethernet and Fast Ethernet were calculated by adding 20 bytes to each frame size to account for 0.96 microsecond inter-frame gap (equivalent to 12 bytes) and preamble (8 bytes).

Thus, the maximum Ethernet frame rate in pps for a IP Datagram of X bytes is:

(10,000,000 Bit/s)/((8 Bits/ Byte)*(X+18+20))

and, the maximum Fast Ethernet frame rate in pps for a IP Datagram of X bytes is:

(100,000,000 Bit/s)/((8 Bits/ Byte)*(X+18+20))
