Standard Features
The VB6000 WM Appliance supports approximately 40 Mbits/sec total throughput via the
Ethernet/IP connection. This bandwidth can be used for any of the standard features shown
in Table 1 but the overall performance of any one of these features can be affected by the
sum total. For example, you can download more content from the hard drive when the
encoder(s) are not streaming, pushing, and/or multicasting. In a typical scenario, the hard
drive will support the progressive download of a video file to a maximum of 20 simultaneous
viewers, or 20 MBits/sec—whichever comes first.
