Emerging multiple service broadband networks will support applications with diverse performance objectives and traffic characteristics. The evolution from the current "Best Effort" service, to QoS-enabled IP services should be performed in a smooth and scalable way. MUSE architecture exploits the combination of class-based forwarding and per-flow admittance in order to yield a promising, effective and scalable solution. In order to support also migration scenarios, the proposed architecture is generic enough to cover different access technologies with multiple link rates. Although multiple mechanisms on different planes should be incorporated, the goal is the same; to provide service provisioning with quantitative and qualitative measures for customers' satisfaction. Our attention is focused on data plane and especially on the behavior of the Residential Gateway (RGW). This paper gives a simulative performance analysis of the proposed traffic differentiation and buffer settings effects when applied on the QoS block of the RGW. Performance results are derived from real network traffic simulations on a model based on the proposed architecture and functionality of the gateway for relatively slow access lines. The results will show the special features of the applied MUSE architecture and will highlight its capability to provide predefined qualitative metrics on the RGW node so that the operators could build a well-engineered network, achieving QoS provisioning in the access network.

I. INTERNET QUALITY OF SERVICEReal-time networked applications depend on network parameters such as bandwidth, delay, jitter (interpacket delay variation), and loss for their correct operation. The degree of tolerance or sensitivity to each of these parameters varies widely from one application to another. Critical applications, such as remote surgery and online trading systems, require reliability of such parameters as well as guaranteed delivery. Emerging applications such as home networking, intelligent appliances, factory supply-chain networks, as well as the vast majority of multimedia applications also require different levels of service quality from the underlying network in terms of these parameters. In traditional circuit-switched networks such as the telephone system, the quality of a connection can be measured and guaranteed in terms of connection setup delays, media quality (e.g., voice or video quality), and trunk availability. On the other hand, packet-switched networks, such as the current Internet, were not designed to provide per-connection service guarantees. As a result, packets of a particular flow can reach their destination via different paths and experience different amounts of delay, jitter, and loss along the way. This is a critical problem on the current Internet as more and more applications, originally developed for circuit-switched networks, are being migrated onto the Internet.The current Internet architecture is based on the "best-effort" service model, which has worked well for traditional applications such as e-mail, file transfer protocol (FTP), telnet, and hypertext transfer protocol (HTTP). Most of these applications are based on the transmission control protocol (TCP) suite, which provides reliable data delivery service without guaranteeing any delay and jitter bounds. On the other hand, supporting real-time and business-critical applications over a wide-area network requires classification of the application traffic and service-level guarantees from the underlying network for each class of traffic based on a number of factors. A number of proposals have been put forward to enhance the reliability and efficiency of the current Internet. A major objective of these proposals is to provide multiple service classes for either individual flows or flow aggregates with a quality that is suitable for these flows. Once implemented, such service classes will enable
