Abstract

A system, apparatus, and method are disclosed for providing quality of service (QoS) for a network data connection. The network data connection uses a network protocol selectable from a plurality of network protocols. A QoS module can receive a request for a generic QoS and apply this to the network protocol using a specific QoS associated with the protocol. The QoS module may include features for automatic management of QoS and a user interface for changing data connection parameters.
