Abstract

In-sequence media packets that arrive at a media server are processed immediately, and a buffer at the media server is checked for packets whose processing was previously deferred due to out-of-sequence arrival. Any in-sequence packets in the buffer are also processed and forwarded immediately after the processing and forwarding of the received in-sequence packet. Processing and forwarding are deferred for out-of-sequence packets, i.e., packets that are higher in the sequence than the next expected packet, by placing the out-of-sequence packets in the buffer. When a packet is placed in the buffer, a timer is initiated for the missing packet(s). If a pre-determined time passes without the receipt of a missing packet, the missing packet is declared lost and the next-in-sequence received packet is processed and forwarded toward the destination.
