A method, system and computer program product of prioritizing network services is provided. Such prioritization may include a better level of service, more timely system response and/or preferential treatment of traffic. In an embodiment, prioritization is controlled by defining modes and levels of prioritization typically based on criteria, such as the value of a transaction, the standing of a user, or the type of transaction. Prioritization can also be established, for example, for a length of time or for a given transaction. The modes of prioritization may include remapping TCP ports to which a communication is directed, remapping uniform resource locators and/or Internet Protocol addresses to which a communication is directed and/or tagging communications with quality of service information. The levels of prioritization define the type(s) of priority service offered to a user, such as timeliness of system response and preference of traffic treatment, and may be arbitrarily defined.
