The network interface module receives audio packets from the network, decapsulates them, determines if any packets were lost, and passes the audio data in IObufs as EVX events to the audio decompressor module. Clearly this will require addressing the issues described in 5.2.1. An important consideration as I am designing and implementing the packet aggregation adaptation will be maintaining the generality of the interface between the adaptation and the router since I will also be implementing and analyzing other adaptations later on. A Real-Time Transport Protocol , Internet Draft, July 30, 1993. In a wide area network, packets of data sent by a real time file server to remote clients must cross through network bridges, routers, and hubs, any of which could drop or delay packets, resulting in poor playback quality.
Many years are likely to pass before all nodes in the Internet are updated to run such software.
Mostly, these mechanisms have focused on regulating competition for network resources among traffic sources at the network level. The real-time transport protocol . Architecturally , the ISS is a distributed, parallel mass storage system that uses UNIX workstation technology to provide a low cost, scalable implementation. Ultimately this is limited by the parallelism inherent in the data. As long as packets within the network can be reordered or experience variable delays, isochronous applications require an end to end mechanism to reconstruct the source timing relationships between packets.
