Introduction

RealNetworks' streaming service uses the following protocols:

• PNM (TCP on port 7070, UDP from server -> player on ports 6970-7170)
• RTSP (TCP on port 554, similar UDP as above, but often on multiple ports)
• PNM was our original, but now mostly legacy, protocol used in our versions 1 through 5.
• There's also a HTTP/TCP-only fallback mode which is (usually) on port 8080.

Architecture

Configuration Example

VS/NAT

Run the follwing script on LB Server:

ipvsadm -A -t 192.168.9.244:554  -s rr
ipvsadm -a -t 192.168.9.244:554  -r 192.168.0.150 -m
ipvsadm -a -t 192.168.9.244:554  -r 192.168.0.160 -m

Run

realplay rtsp://192.168.9.244/test.rm

for a test.
