pom:match:rtp

match_rtp

This module match RTP packets. RTP packets are most of the time encapsulated in UDP datagrams. Because of this, it's impossible to determine that a UDP datagram contains a RTP packet. You have to tell packet-o-matic that a packet contains RTP packet or it won't be able to find it out. This is done simply by creating a rule that containes the RTP layer. For example, the following rule assume that all UDP datagrams from 10.0.0.0/8 are RTP packets :

ethernet | ipv4.src == 10.0.0.0/8 | udp | rtp

This module has the following fields :

Field name Field type Description
payload_type uint8 Payload type, see RTP parameter number assignement for a list of value
ssrc uint32 Syncronization source
seq uint16 Sequence number
ts uint32 Timestamp of the packet
