Under the auspices of the IEEE 802.3 Working Group, Ethernet has developed into one of the most widely deployed networking technologies in the world. Ethernet’s unrelenting advances have allowed it to become the dominant technology for Enterprise networking. Data rates have increased from 10Mbps to Gigabit speeds. Links have gone from half to full duplex. [...]

Introduction to iSCSI As Ethernet begins to enter into the Storage world a new protocol has been getting a lot of attention. The Internet Small Computer Systems Interface or iSCSI, is an end-to-end protocol for transporting storage I/O block data over an IP network. The protocol is used on servers (initiators), storage devices (targets), and [...]

XAUI, the 10 Gigabit Attachment Unit Interface, is a technical innovation that dramatically improves and simplifies the routing of electrical interconnections. Developed by the IEEE 802.3ae 10 Gigabit Ethernet Task Force, XAUI delivers 10 Gb/s of data throughput using four differential signal pairs in each direction. Its compact nature and robust performance makes it ideal [...]

Please note this paper may be partially outdated (Revision 2, Draft A • April 2002) whitepaper continued below 10 Gigabit Ethernet Technology Overview From its origin more than 25 years ago, Ethernet has evolved to meet the increasing demands of packet-switched networks. Due to its proven low implementation cost, its known reliability, and relative simplicity [...]

Gigabit Ethernet (GigE) is becoming more and more popular. The accelerating growth of LAN traffic is pushing network administrators to look to higher-speed network technologies to solve the bandwidth crunch. These administrators—who typically have either Ethernet or FDDI backbones today—have several alternatives to choose from. Although each network faces different issues, Gigabit Ethernet meets several [...]

This is the second page of the whitepaper Optical Fiber and 10 Gigabit Ethernet. Part1: here MultiMode Fiber Multimode fiber is used extensively in the campus LAN environment where distances between buildings are 2 km or less. The broad market penetration and acceptance of 62.5/125 micron multimode fiber was initiated by its inclusion in the [...]

Introduction As 10 Gigabit Ethernet (10GbE) is introduced into networks the physical limitations and properties of optical fiber introduce new challenges for a network designer. Due to the increased data rate, fiber effects, such as dispersion (intermodal, chromatic or polarization), become a factor in the achievable distances of 10GbE links. This leaves the network designer [...]

Introduction Two different testing philosophies have evolved in our communications networks: a "perfection" approach, under which the Device Under Test (DUT) is subjected to signals produced by test equipment whose performance exceeds the DUT’s required specifications and a "worst-case" approach that subjects the DUT to signals that simulate those likely to be encountered in the [...]
