<p><span>Wireless local area networks (WLAN) has been used recently due to their benefits which exhibits outstanding mobility with easier and faster configurations. The wireless local area network performance is much influenced by both network topology and hardware specifications and thus will impact the quality of service (QoS) parameters which are delay, load, and response time. This works estimated the performance of WLAN in enterprise WAN based on the OPNET modeler. Three scenarios have been suggested which are FDDI scenario, FDDI Hybrid Star scenario, and FDDI hybrid ring scenario involving web browsing (HTTP) and file transfer protocol (FTP). Hardware objects and software configurations kept the same for all proposed scenarios. Different types of links and topologies have been applied among WLAN subnets as well as the involved gateway has been changed to measure parameters of quality of services (QoS) for all scenarios used. The findings confirmed that the FDDI Hybrid Ring scenario presents better performance than the FDDI Hybrid Star Scenario and FDDI scenario in terms of WLAN delay, WLAN load, FTP download response time, and HTTP object response time.</span></p>

“…Quality of Service on the LAN represents a major challenge, not so much during the predictable processes of compressing the voice streams and splitting them into packets which are mathematically predictable, the real challenge is of sharing the connectionless transmission media with other users in a predictable and quantifiable way. As soon as voice/video traffic reaches the IP network, it must compete with electronic mail traffic, database applications and file transfers [13], [17], [18].…”

The present paper relates to performance and quality of service evaluation for VoIP (Voice over IP) and desktop videoconferencing services in IP networks. Simulation-based performance measurements consist in the generation of performance statistics obtained by measurements realized by simulation on the subscriber interface. They include detailed measurement of call quality, call setup quality and availability. The tests are accomplished by emission of non-disturbing additional test traffic. The real-time QoS monitoring is based on non-intrusive analysis of real call parameters. The advantage of this method is the exhaustiveness of the analyzed call. The QoS measurements are mainly service availability and call setup quality. Performance Measurement Methodologies and Quality of Service Evaluation 93 convert network layer performance (ATM, AAL) to transport layer performance, according to the selected services: telephony over IP, file transfer over IP and videoconferencing over IP [12], [14]. 1.1 QoS Characterization The used TCP/IP model can be described as follows: telephony over IP file transfer video conferencing overIP WAN RTC LAN Ethernet ATM AAL5 copper, xDSL UTP, fiber 10M STM1 155M IP protocols + extensions

“…Since the Internet was opened to commercial traffic, it has grown rapidly from an experimental research network to an extensive public data network [1]. Demand is pushing the capabilities of today's Internet in several dimensions including, but not limited to, transmission bandwidth, number of hosts, QoS, geographic size and traffic volume [4]. At the same time, the Internet is evolving from best-effort service towards a service framework with QoS assurances, which will be necessary for many new applications such as voice over IP (VoIP), videoconferencing, and multimedia, adapting to the needs of its users and incorporating new technologies as it has been developed.…”

New technologies based on Label Switching, recently proposed, have been developed as a result of various motives. These approaches represent the next generation switching networks. The most popular ones are the Cell Switching Router (CSR) from Toshiba, IP Switching from Ipsilon, Tag Switching from Cisco and Aggregate Route Based IP Switching (ARIS) from IBM. All of them are based on the switching mechanism called Label Swapping, but each implementation is quite different from the others. They all enable Network Service Providers to solve many of the issues that they struggle today. These issues include the explosive growth of the Internet and the requisite scalability of service provider networks, the ability to offer Quality of Service (QoS) to enable voice, video, and multimedia applications over IP, and to offer differentiated services such as Virtual Private Networks (VPNs). This paper aims to show some of the main characteristics of Label Switching, in addition, it presents a global view of all approaches mentioned above, differences and comparisons among their key aspects.Label Swapping, the same technique that, not coincidentally, is used to forward data in ATM switches.Unlike ATM, all Label Switching techniques strive to maintain the control paradigm of the IP (Figure 1). They use the IP addresses and standard Internet routing protocols. Thus, in many aspects, they combine the best of ATM with the best of IP, like it was mentioned above. There are also many significant differences among the approaches, such as the use of either data or control traffic to drive the establishment of forwarding state.The standard in this area, which has been defined by the IETF, is called MPLS (MultiProtocol Label Switching). It is a neutral term to refer to these techniques.
