AVERAGE DELAYS ASSESSMENT OF TELECOMMUNICATION INFRASTRUCTURES AND INTERCONNECTING CHANNELS OF DATA PROCESSING CENTERS IN WEB SCALE ARCHITECTURE
Abstract
In this article are considered standard architecture of the Data Centers (DC) and a tendency of their combining within the concept of Web Scale in communication by development of technologies of virtualization, "cloudy" services and requirements of more and more fast delivery of the increasing content volumes with appropriate quality of service (QoS). The proposed formulas estimates the average cross-network delay of channel interconnects for Data Centers in architecture of Web Scale and average delay of DC telecommunication infrastructure of arbitrary architecture taking into account effects of self-similarity of a traffic and loss of packets. The characteristic of the special software of Data Center Bridging (DCB) and hardware functionality of the active network equipment necessary for operation in specific operating conditions of Data Centers is also this and the appropriate models D-Link switches are provided.
