Class PortRange

Class to manage port allocation for Rtp Ports. Ports are always even, because due Rtp data and control ports are always with data on even port and control (if any) on data_port + 1

There are two operation modes:

  • The sequential mode which hands out all ports within the assigned range and wraps around if the last port was assigned
  • The shuffled mode: Ports are handed out evenly distributed within the assigned port range.
