Ethernet-over-Sonet Tutorial In order to support increasing data traffic levels‚ equipment developers must build systems that map Ethernet packets over Sonet/SDH links. In this two-part series we’ll lay out the encapsulation techniques required to make Ethernet-over-Sonet come to life. Today’s incumbent service providers are seeking to accommodate increasing demands for bandwidth‚ security and service level management resulting from the proliferation of LAN-based applications. According to RHK

concept of Power over Ethernet (PoE) was born. This paper provides a research of PoE and its advantages‚ and the fundamental changes brought about by this technology to commercial and industrial applications. An overview of the advancements on the technology is provided as well. The Story behind the success Power over Ethernet or PoE technology describes a system to safely transfer electrical power‚ along with data‚ to remote devices over standard data cables in an Ethernet network (Cat 3/Cat5/Cat5e/Cat6)

ABSTRACT In this paper‚ we will conduct a comparison on Fast Ethernet Network Switches and Gigabit Ethernet Network Switches offered by 3COM. We will review a few specific components‚ as well as compare features‚ pricing and preferred usage. DEFINITION In order to have a greater understanding of the terminology and descriptions offered in this paper‚ we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network

Ethernet Systems communicating over Ethernet divide a stream of data into shorter pieces called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. The Ethernet provides services up to and including the data link layer. Since its commercial release‚ Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols

STANDARD DEVIATION The standard deviation is a popular measure of variability. It is used both as a separate entity and as a part of other analyses‚ such as computing confidence intervals and in hypothesis testing. The standard deviation is the square root of the variance. The population standard devia¬tion is denoted by σ. Like the variance‚ the standard deviation utilizes the sum of the squared deviations about the mean (SSx). It is computed by averaging these squared deviations (SSX/N) and
