IP RTP COMPRESSION

[patcbr600]

Hello,

I have configured ip rtp header compression on my network:

This is the output from the show command:

CE-CF-Aveiro#sh ip rtp header-compression multilink 1

RTP/UDP/IP header compression statistics:

We're compressing using MQC profiles, use the

0 dropped, 0 buffer copies, 0 buffer failures

Sent: 381379 total, 376798 compressed, 0 status msgs, 183167 not predicted

12609923 bytes saved, 10791795 bytes sent

Connect: 64 rx slots, 64 tx slots,

Does any one know what is the meaning of : 183167 not predicted

Thanks.

Do you have an RSVP enabled ? If not I guess those numbers relate to those packets which were not compressed using RSVP Predicted compression.

Hello,

I dont have rsvp enable , on a document i read that not predicted packets are packets that take a non optimal path true the compressed.
