[Live-devel] 4+ Connections ->Stream Proxy Server High Packet Loss Rate

[许凯军]

Dear, Ross,
My test environment:
Rtsp camera ip: 10.64.59.158
Live555 Proxy Server Install at :10.64.62.41
Rtsp Stream Client at: 10.64.59.27

Rtsp Client num

Rtsp Server Address

Loss Rate

1

10.64.62.41

0.000000

2

10.64.62.41

0.000000

3

10.64.62.41

0.000000

4

10.64.62.41

0.005000 +

9

10.64.62.41

0.040000 +


However, If rtsp client and proxy server install in the same computer 10.64.59.27
Rtsp Client num

Rtsp Server Address

Loss Rate

4

10.64.59.27

0.000000

10

10.64.59.27

0.000000

20

10.64.59.27

0.001000 +



rtsp client connect camera directly
Rtsp Client num

Loss Rate

4

0.000000

10

0.000000

15

0.000000



I cannot fix out the reason why if the proxy server and client run at different computer will lead to high packet loss rate?
