3.2.3. Cell Loss Ratio (CLR)
3.2.3.1. CLR/Steady Load/One VCC
Objective: To determine the SUT ratio of lost cells on one VCC in a transmission in relation to the total cells sent as defined in RFC 2761 "Terminology for ATM Benchmarking". Procedure: 1) Set up the SUT and test device using the bi-directional configuration. 2) Configure the SUT and test device with one VCC. The VCC SHOULD contain one VPI/VCI. The VCC MUST be configured as either a CBR, VBR, or UBR connection. The VPI/VCI MUST not be one of the reserved ATM signaling channels (e.g., [0,5], [0,16]). 3) Send a specific number of IP packets at a specific constant rate through the SUT via the defined test VCC. Since this test is not a throughput test, the rate should not be greater than 90% of line rate. The IP PDUs MUST be encapsulated in AAL5. 4) Count the IP packets that are transmitted by the SUT to verify connectivity and load. If the count on the test device is the same on the SUT, continue the test; else lower the test device traffic rate until the counts are the same. 5) Record the number of cells transmitted and received on the test device.
