+####2.3.3 Scalability tests
+
+  The general aim of these tests is to understand the impact of large flow table size and flow lookups on throughput.
+
+  The following list is not exhaustive but should indicate the type of tests that should be required. It is expected that more will be added.
+
+<br/>
+ - #####Test ID: LTD.Scalability.RFC2544.0PacketLoss
+
+  **Title**: RFC 2544 0% loss Scalability throughput test
+
+  **Prerequisite Test**:
+
+  **Priority**:
+
+  **Description**:
+
+  The aim of this test is to measure how throughput changes as the number of flows in the DUT increases.
+
+  For each frame size previously defined under [Default Test Parameters](#DefaultParams) and for each of the following number of flows:
+
+  - 1,000
+  - 2,000
+  - 2,000
+  - 4,000
+  - 8,000
+  - 16,000
+  - 32,000
+  - 64,000
+
+  The maximum 0% packet loss throughput should be determined in a manner identical to LTD.Throughput.RFC2544.PacketLossRatio.
+
+  **Expected Result**:
+
+  **Metrics Collected**:
+
+  The following are the metrics collected for this test:
+
+   - The maximum number of frames per second that can be forwarded at the specified number of flows and the specified frame size, with zero packet loss.
