Abstract: This paper first discusses active service architecture, which is generally used in promulgating continuous media over network. In designing the controlling protocol SCACP, soft-state protocol, light-weighted session architecture are investigated, measured and adopted, some problems such as agent flood damping, controlling bandwidth restriction, error toleration and restoration, and session splitting and emerging are also discussed.
