Type of network service the application uses.
If the application uses enhanced network service, for instance Integrated Services or Differentiated Services, it has not to ensure fair competition with TCP, provided that the requested service is actually being delivered. Whenever the application uses best-effort service or the requested enhanced service is not actually being delivered, it has to ensure fair competition with TCP. By default, best-effot is assumed.

Get the clock rate in RTP clock units (for instance, 8000 units per second for PCMU, or 90000 units per second for MP2T).

Get the timestamp that should be given for a packet whose payload sampling instant corresponds to the current system time.
The timestamp applications should provide for each packet represents the sampling instant of its payload and should not be a reading of the system clock. Nevertheless, the internal operation of the RTP stack relies on the accuracy of the provided timestamp, since several computations assume that there is a certain degree of correspondence between the timestamp and the system clock.
It is recommended that applications use this method in order to periodically adjust the RTP timestamp.
In particular, it is advisable getting the timestamp corresponding to the first sampling instant or any instant after a period of inactivity through a call to this method.
Applications should use the nominal sampling or any other value provided by the coder in order to compute the next timestamps with minimum computational requirement.
For instance, an application using an RTP profile that specifies a fixed sampling rate of 8 Khz with eight bits per sample, continuously transmitting audio blocks 80 octets long, would transmit 100 packets every second. Every packet would carry a timestamp 80 units greater than the previous one. So, the first timestamp would be obtained from this method, whereas the following ones would be computed adding 80 every time. Also the timestamp should be increased for every block whether it is put in the queue or dropped.
The aforementioned increment can be obtained from the RTPDataQueue::getTimestampIncrement() method rather than computing it by hand in the application.

Perform NAT table lookup for this socket.
Used to allow an application to know the original ip:port pair the the client "thinks" it is connecting to. Used mostly to transparently impersonate a remote server/service.
On error, 0.0.0.0:0 is returned and one of the following error codes is set: errServiceUnavailable - if nat is not supported on the current platform or if it was not compiled; errLookupFail - if the nat syscall failed for some reason (extended error code); errSearchErr - if the socket does not have nat information (i.e. is not nated).
NAT lookup is supported on NetFilter for ipv4 and ipv6 (Linux), IPFilter for ipv4 (Solaris, *BSD except OpenBSD, HP-UX, etc.) and Packet Filter for ipv4 and ipv6 (OpenBSD). When using IPFilter or Packet Filter, the first NAT lookup must be performed as root (the NAT device is read only for root and is opened once, unless an error occurs). Permissions on the nat device may be changed to solve this.
