• Provide PrrtCodingConfiguration.__eq__() method.
• Add PrrtCodingConfiguration.ri(channelParameters) method that yields how much redundancy this coding configuration causes, given a certain channel.
• Add is_valid_for(applicationParameters, channelParameters, systemParameters) method to check if it is able to fulfill application parameters given channel and system parameters.
  • Add is_maximum_latency_fulfilled(applicationParameters, channelParameters, systemParameters)
  • Add is_maximum_loss_fulfilled(applicationParameters, channelParameters, systemParameters)
