Top1. Introduction
This network model is based on a campus network. An Application Configuration is setup with default parameters which specify 8 common applications used. Among them the ones that I will focus on are VOIP, Video and FTP (Chong & Matthews, 2004; Lindgren, Almquist, & Schelen, 2002). Voice packets are transmitted over IP-based networks. VoIP is a real-time application and transmits the voice on a Real-Time Transport Protocol (RTP), User Datagram Protocol (UDP) and Internet Protocol (IP) over networks (Cai, Ling, Shen, Mark, & Cai, 2009). Each voice packet is small in size and the voice packet has the headers: RTP (12 bytes), UDP (8 bytes), and IP (20 bytes) headers. The data-link layer Medium Access Control (MAC) has a (34 bytes) header. All these headers sum up to 74 bytes of overhead in the VoIP application. The Session Initiation Protocol (SIP) was considered to handle a multimedia call setup and H.323 is considered by ITU to allocate IP-based phones on the public telephone network to talk to a PC-based phone over IP-based networks (Ehlert, Zhang, & Magedanz, 2008). It is a standard that specifies the components, protocols and procedures for multimedia communication services such as real-time audio, video and data communications over IP-based packet networks (Hasbullah, Nisar & Said, 2009; Nisar, Said, & Hasbullah, 2010). A Profile Configuration is setup that will define the 3 applications stated. A fixed node model of 100BaseT will specify the profile configuration for each scenario and the number of work stations of each scenario. Ethernet Servers and Ethernet switches have been used linked with 100BaseT Duplex links.
The following scenarios have been implemented:
- •
FTP Traffic on a network with 2 workstations
- •
FTP Traffic on a network with 10 workstations
- •
FTP Traffic on a network with 50 workstations
- •
FTP Traffic on a network with 100 workstations
- •
VOIP Traffic on a network with 2 workstations
- •
VOIP Traffic on a network with 10 workstations
- •
VOIP Traffic on a network with 50 workstations
- •
