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
| VIP/EXT IP | 192.168.9.244 |
| GATEWAY IP | 192.168.0.1 |
| RS1 | 192.168.0.150 |
| RS2 | 192.168.0.160 |
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.
VS/DR
| VIP/eth0:0 | 192.168.9.200/24 |
| LB/eth0 | 192.168.9.244 |
| RS1 | 192.168.9.150 with lo0:0 192.168.9.244/32 noarp |
| RS2 | 192.168.9.160 with lo0:0 192.168.9.244/32 noarp |
Run the follwing script on LB Server:
ipvsadm -C ipvsadm -A -t 192.168.9.200:554 -s rr ipvsadm -a -t 192.168.9.200:554 -r 192.168.9.150 -g ipvsadm -a -t 192.168.9.200:554 -r 192.168.9.160 -g
Run
realplay rtsp://192.168.9.200/test.rm
for a test.
