The recent Quality of Service (QoS) architecture proposed by the Internet Engineering Task Force (IETF) enables a set of new network services providing possible solutions to improve the quality of the Internet-based services. The interest of this research is to find a customizable QoS network solution for the Internet based share trading business by deploying these QoS architectures in order to address the quality issues in the Internet Share Trading Business. The construction of the QoS theoretical framework begins with the identification of the Internet service capabilities required by the Internet share trading business through a case study. The appropriate QoS architectural design is selected through matching the existing QoS architectures with the identified service capabilities. The QoS technological strategies and QoS capabilities are thus derived from the selected QoS architectural design. Additionally, the effectiveness of the proposed QoS architectural design is evaluated against the current implementation by using computer simulation.
