<p>A system and method for the optimized storage and retrieval of video data at distributed sites calls for the deployment of 'Smart Mirror' sites throughout a network, each of which maintains a copy of certain data managed by the system. User addresses are assigned to specific delivery sites based on an analysis of network performance with respect to each of the available delivery sites. Generalized network performance data is collected and stored to facilitate the selection of additional delivery sites and to ensure the preservation of improved performance in comparison to traditional networks.</p> |
