Abstract
Methods and apparatus for assigning bandwidth to a network based on two or more different service levels. In an exemplary embodiment, video on-demand (VOD) session requests within a service group of an HFC cable network are assigned bandwidth such that maximum opportunity is given to grant HD VOD request among SD VOD requests, while meeting the goal of minimizing service disruption by spreading the sessions over multiple QAM channels, and limiting the maximum number of active VOD sessions of any kind.
