The present disclosure discloses a method and network device for dynamically prioritizing user connections on network. The disclosed system identifies a priority class associated with a client device prior to an initial connection from the client device to a network, and reserves access to a network resource for the client device based on the priority class prior to the initial connection. Specifically, the system evaluates a total capacity of the network resource and an anticipated usage of the network resource by the client device associated with the priority level. Then, the system will reject requests for accessing the network resource received from other client devices prior to the client device associated with the priority level accesses the network resource.
