Ethernet – The Next Generation WAN Transport

Ethernet Transport and its Service Technology To understand why Ethernet is a viable transport for the WAN, it’s important to note the various technology that surrounds and supports Ethernet.   Figure 1 shows Ethernet’s circle of technology. At the core, Ethernet is supported within fiber, copper, and even wireless media. In addition, bandwidth support for [...]

10 Gigabit Ethernet Interconnection with Wide Area Networks

By far, the most widely used networking technology in Wide Area Networks (WANs) is SONET/SDH. With the growth of Ethernet now into Metropolitan Area Networks (MANs) there is a growing need to interconnect Ethernet LANs and MANs to these prevalent SONET networks. With the advent of 10 Gigabit Ethernet, the commonality of line rates between [...]

10 Gigabit Ethernet standard ( 10ge )

Under the International Standards Organization’s Open Systems Interconnection (OSI) model, Ethernet is fundamentally a Layer 2 protocol. 10 Gigabit Ethernet uses the IEEE 802.3 Ethernet Media Access Control (MAC) protocol, the IEEE 802.3 Ethernet frame format, and the minimum and maximum IEEE 802.3 frame size. Just as 1000BASE-X and 1000BASE-T (Gigabit Ethernet) remained true to [...]

TCP/IP offload Engine (TOE)

Introduction to the TCP/IP offload Engine Ethernet has become the most popular networking protocol for local area networks (LANs). It is inexpensive and offers plugandplay implementation. As networking has grown in popularity, Ethernet network link speeds have also been increasing. The growth of Ethernet from 10 Mbit/s to 10 Gbit/s has surpassed the growth of [...]

1000BASE-T

1000BASE-T – running Gigabit Ethernet over Copper INTRODUCTION  When network managers decide on a cabling system, they make a decision that is basic to the network infrastructure and long term in its horizon. With the ratification of 1000BASE-T in June 1999 (IEEE 802.3 Ethernet Standard for Gigabit Ethernet on Category 5 copper), network managers are [...]
