In traditional switched LANs, the physical topology is closely related to the logical topology. • Generally, workstations must be grouped by their physical proximity to a switch. • To communicate among LANs, each segment must have a separate port on the backbone device or a connection to a common backbone.

In 1985, the Computer Society of the IEEE started a project, called Project 802, to set standards to enable intercommunication among equipment from a variety of manufacturers. Project 802 is a way of specifying functions of the physical layer and the data link layer of major LAN protocols.

In random access or contention methods, no station is superior to another station and none is assigned the control over another. No station permits, or does not permit, another station to send. At each instance, a station that has data to send uses a procedure defined by the protocol to make a decision on whether or not to send.

The data link layer needs to pack bits into frames, so that each frame is distinguishable from another. Our postal system practices a type of framing. The simple act of inserting a letter into an envelope separates one piece of information from another; the envelope serves as the delimiter.

Laser-Optimized Fiber: Built for Price, Bandwidth, and Distance to Make the Most of Your Investment Over the past 25 years, Ethernet standards have evolved from 10 Mbps and 100 Mbps to Gigabit and now 10 Gigabit. The rapid growth of Internet use and bandwidth-intensive applications combined with routine transmission of large files is driving the need for 10 Gigabit Ethernet (10GbE) in many network backbone and data center connections. Implementation is happening all around us. Sales of 10GbE switch ports are increasing dramatically, and will continue to grow over the next decade.
