The current Internet provides a best effort service and doesn't guarantee the quality of service. In the Internet telephony, the application level control mechanism is required to support the transmission of real-time audio. Most FEC-Based error control algorithms, which add redundant information to audio packets, were proposed to minimize the effects of packet loss. Because these algorithms don't consider the end-to-end delay resulted from the redundancy, increasing the amount of redundancy may exceed the acceptable maximum delay. This paper proposes an Adaptive FEC Error Control algorithm using both loss and delay to control the amount of redundancy and not to exceed the maximum delay. The performance tool and real Internet is able to maintain the end-to-end delay below the maximum delay and lower loss rate than the existing algorithms.
