Hi,
Looking at the link you provided it says:
Assume that Wowza can only serve only 5 Gbps,
Some of our customers have been able to get up to 10Gbps of streaming performance for both live and on-demand on multi-threaded, multi-CPU machines that were finely tuned at the kernel level. On standard servers with dual quad-core processors and multiple NICs, up to 5Gbps of streaming performance can be achieved if the server is properly tuned. Tuning guidance is available in our Performance Tuning Guide.
Going off the stream bitrate (600 Kbps) and the concurrent connections at peak time (50,000 users), you will need around 8 servers at this specification.
600 Kbps x 50,000 users = 30 Gbps which is impossible with one server limited a maximum of 5 Gbps.
Realistically you’re looking at 6,650 connections per server assuming a 5 Gbps connection is available, giving a 20% overhead.
600 Kbps x 6,650 = 3.99 Gbps
50,000 /6,650 = 7.51
50,000 = Total users, 6,650 = Connections per server and 7.51 = Servers needed.
