The distribution of frame sizes of VDI traffic handled by the S6000 is shown below. Because the
VMware default frame size is 1300 bytes, the frame size of 1024-1518 is the largest portion of
the pie chart that shows distribution of traffic by frame size.
Figure 7: Frame Size Distribution, 200-User Quality of Experience Testing
This was the frame-size distribution in the Quality of Experience testing for 200 users. Note that large
packets, 1024-1518 bytes, make up nearly half of the distribution. This distribution was used in to construct
the frame distribution used in scalability testing for 10,000 users.
Then, the Ixia XM12 was utilized to inject fully meshed, custom IMIX traffic that was equal to or
more than that needed to support 10,000 VDI sessions. The distribution of frame sizes was
similar to that utilized in initial testing of end-user QoE for 200 users.
Figure 8: Fully Meshed Traffic Generated by Ixia XM12
This diagram shows the path of fully meshed traffic between the Ixia XM12 traffic generation test and a
generic Device under Test (DUT).
