A method and apparatus generate a forward error correcting code for use with a plurality of source packets to be transmitted over a network. In one exemplary embodiment, the method comprises identifying a plurality of candidate packet masks and selecting that one of the masks that has the lowest expected residual packet loss value ("RPL"). RPL is calculated using an effective recovery rate, which in turn is a function of at least one network performance parameter (such as packet loss) and one or more channel code parameters such as the number of source packets and/or FEC packets. The error correcting code can be generated using the selected packet mask and at least one of the source packets. |
