Interactive video on demand over high speed networks

摘要

Interactive Video on Demand with Instantaneous Access (IVoD-i) can offer users with VCR like functions by sending requests to video servers. Earlier work has shown that the Available Bit Rate Service of ATM networks can be effectively used for interactive video on demand. However, non optimal values of the connection setup parameters can affect the Quality of Service (QoS) at the user. This is because the ABR service only provides minimum bandwidth guarantee for a connection. The objective of this paper is to provide QoS to IVoD-i over the ABR service of ATM. To achieve this objective, we have developed an analytical framework to determine the ABR connection parameters to guarantee QoS to IVoD-i users. Our proposed framework has been tested with real life MPEG video traces. Results show that our framework can provide QoS to IVoD-i users. Moreover, our framework outperforms previous schemes in terms of startup delay, user buffer requirement, and jitter.
