An Emperical [i.e. Empirical] Study of Video Application Performance Over ATM and Ethernet Networks

Abstract: "Over the past few years, there has been a strong and growing interest in faster network technologies such as FDDI and ATM. However, the perceived throughput at the application level has not always increased accordingly. Various performance bottlenecks have been encountered each of which has to be analysed and corrected. This paper presents a performance evaluation of continuous video data streams over ATM networks and compares them with similar experiments over Ethernet networks. The ATM LAN testbed for these experiments consists of three SG R4000 Indigos workstations connected by ATM Fore first generation interface cards and a Synoptics ATM switch. It is expected that video applications would run faster on ATM networks than Ethernet networks. A preliminary examination suggested to us that data movements through the protocol stack and the processing overheads were considerably high and that with some parameter settings, experiments with Ethernet would perform four to five times better than those with ATM. To address and explore this issue, a packetisation process has been added within the video application that would split each video frame into a number of packets. We show that by implementing a packetisation process at the application level, the end host is able to deliver cells at a faster rate. The sensitivity of these parameters, and also the overheads involved are discussed. The results are consistent over a range of video frame sizes: CIF(25 K), QCIF(101 K), and SCIF(405 K)."

History of Humanity: From the seventh to the sixteenth century

Volume IV deals with the 'Middle Ages'. It starts with the expansion of Islam and closes with the discovery of the New World. Various events during this period led to a significant expansion in communications: the rapid spread of Islam and of Gengis Khan's Mongol Empire, as well as the Crusades and the development of trans-Saharan and maritime routes around Africa to the Indian Ocean, leading to multiplied exchanges between the peoples and cultures of Africa, Asia and Europe.

When the seat of the caliphate moved to Damascus with the Umayyads, the new capital also became an important cultural centre. Muslim learning truly began with the commencement of the writing of the Qur'an in AD 650.
