Hi Friends, I am facing video buffering issue in video streaming device. as my internet speed is fine and when i check internet speed test its shows good speed .i have allocated bandwidth for the device and given 30 mpbs bandwidth to the device. after that also video is buffering a lot . i need to find the cause of the issue . when i take packet capture of the device ip address from my firewall . It show more tcp previous segment not captured followed by tcp out of order. i need to find, is the issue is from internet service provider or its from inside lan network configuration or its device issue. Can anyone help me

Hi,

TCP segment not capture may be normal if they are seen at the beginning of a capture or at least if you started capturing packets after the TCP conversation had begun. It can also mean there are dropped packets either on the network or on the capture device. Check Statistics -> Capture File Properties (CTRL+ALT+SHIFT+C) to see if there were drops. (The capture device may not support populating that field.)

Out of order means you are receiving segments in the "wrong" order. Put simply, you ideally want to get segment 1-2-3-4-5 in sequence but you got 1-3-2-5-4. You have them all but just not it the right order. You are not missing data but the host may need to buffer the data and use more CPU to put everything in order for the software. (Again simply put)

You mentioned a firewall and allocating bandwidth to the streaming device but maybe you could try temporarily bypassing the firewall?

Hope this helps.

Cheers,

JF
