Packet losses

Dear All,

 

I am sharing here one of intrestining issue which i have observed in past couple of days frequently,we have observed packet losses in VC call with one of wan side endpoint but the losses could not capture by the wan side or ISP side router.

 

Can any one let us know what kind of packet losses is that whether it is CRC or else because the router only capture CRC losses(major) and is there way to make them capture any comment would be highly appriciated,

 

Thanks

GC

Re: Packet losses

I am assuming that you are talking about seeing packet loss either in the call by freezing video or fast updates, or by looking at the packet loss in the stats.

 

The packet loss in the stats shows the packets which were either not received due to network issues gerneally and would be seen on network monitoring tools, or they are packets that were received by the EP but outside of the latency buffer time.  The packets received late would be considered lost by the video EP but not with network tools as then did make it to the endpoint.

 

The latency buffer can vary and you did not give enough information to state with certainity but they are generally in the 75ms time frame.
