Abstract Increased efficiency is the key ingredient to surviving in today's rapid paced environment. Electronic mail has become a mainstay to both government and business operations. However, to maintain a competitive edge, organizations must move past today's electronic messaging into an integrated data environment where large data files, and video are passed rapidly through the network in a seamless fashion. Organizations must continuously monitor their capability to participate in the...

Abstract This work investigates and studies the performance of voice quality when sent over the ABR service in ATM networks. Sources can modify the rate at which they send traffic to the network based on the feedback carried by the Resource Management (RM) cells. This is achieved by changing the encoding level. As the contention increases in the network resources, (bandwith in this case), sources start to reduce the rate at which they generate and send traffic. The efficiency of the scheme under...

Abstract This thesis proposes new methodologies for the design and performance evaluation of Storage Area Networks (SANs) infrastructures. Designing a storage area network (SAN) fabric requires devising a set of fiber channel switches and links to connect hosts to their storage devices. The network must be capable of simultaneously meeting specified data flow requirements between multiple host-device pairs. We have presented a detailed analytical view of the key architectural switch...
