-## PLRsearch Tests
-
-### Description
-
-Probabilistic Loss Ratio search (PLRsearch) tests discovers a packet
-throughput rate associated with configured Packet Loss Ratio (PLR)
-criteria for tests run over an extended period of time a.k.a. soak
-testing. PLRsearch assumes that system under test is probabilistic in
-nature, and not deterministic.
-
-### Usage
-
-PLRsearch are run to discover a sustained throughput for PLR=10^-7
-(close to NDR) for VPP release covered by CSIT report. Results for small
-frame sizes (64b/78B) are presented in packet throughput graphs (Box
-Plots) for a small subset of baseline tests.
-
-Each soak test lasts 30 minutes and is executed at least twice. Results are
-compared against NDR and PDR rates discovered with MLRsearch.
-
-### Details
-
-See [PLRSearch]({{< ref "plrsearch/#PLRsearch" >}}) methodology section for
-more detail. PLRsearch is being standardized in IETF in
-[draft-vpolak-bmwg-plrsearch](https://tools.ietf.org/html/draft-vpolak-bmwg-plrsearch).
