Need brief explanation of some protocols

[camaro]

I need to find references to the following on the internet and submit a brief explanation of these newer protocols:

* IEEE 802.9
* IEEE 802.10
* IEEE 802.11
* IEEE 802.12

And I also need to search for sites that have installed Fast Ethernet and explain why they chose to use that protocol.

I'd appreciete any help.

IEEE 802 LAN/MAN Standards Committee should get you started w/ the references.

EDIT - This link might prove a little easier to find the info on. Just put whatever 802.xx you want to know about.

Thanks man. I think I got the explanations set.

Anyone can help me with the second part about Fast Ethernet. I've been on Google all day trying to get this done. Thanks.

I thought "Fast Ethernet" was just another term for GigabitEthernet? Is that considered a protocol?

From Intel's web site:

100BASE-T Fast Ethernet operates at ten times the speed of regular 10BASE-T Ethernet, yet can be seamlessly integrated into existing Ethernet installations to deliver high bandwidth performance where it's needed. Rapidly becoming the standard for today's LAN, Fast Ethernet provides a cost-effective solution for the network bottlenecks created by the growing volumes of data generated by today's more powerful desktop PCs and bandwidth-intensive networked applications. Fast Ethernet, together with 32-bit PCI bus architecture, extends the power of high performance desktop PCs onto the LAN.

Challenges addressed:


Compatibility and Interoperability: Adopted June 1995 by IEEE 802.3 committee, this standard has multi-vendor support and retains the familiar Carrier Sense Multiple Access/Collision Detection (CSMA/CD) protocol which enables data to move between Ethernet and Fast Ethernet nodes on the LAN without protocol translation. Fast Ethernet also retains same category 5 cabling support as Ethernet.


Performance: Helps prevent network bottlenecks by providing 10 times the bandwidth of Ethernet.


Planning, Installation & Maintenance: A technology for Evolving Networks that may be experiencing bandwidth problems. Fast Ethernet is a cost-effective migration path if you have Ethernet already. Since it is based on the Ethernet standard—you can use same category 5 cabling and do not need protocol translation between nodes to increase bandwidth by 10 times.


100BASE-T Fast Ethernet
a Natural Evolution from 10BASE-T Ethernet

To expedite development of a Fast Ethernet standard, Intel and a group of leading networking companies formed the Fast Ethernet Alliance in July, 1993. This cooperative effort included over 50 vendors representing all major categories of networking equipment, including adapters, hubs, bridges, switches, routers and management tools. As its name implies, Fast Ethernet is an extension of the proven Ethernet standard and is therefore easily integrated into existing Ethernet networks.

Fast Ethernet was officially adopted in June 1995, by the IEEE 802.3 committee, the group responsible for all Ethernet standards. The standardization and multi-vendor support guarantees a broad range of high-performance, low-cost Fast Ethernet products, ensuring that Fast Ethernet is a leading price/performance solution among high-speed networking alternatives.

Fast Ethernet uses technology that has been working reliably for more than a decade. It retains the familiar CSMA/CD (Carrier Sense Multiple Access/Collision Detection) protocol, enabling data to move between Ethernet and Fast Ethernet nodes on the LAN without protocol translation and retains the same cabling support. This makes it easy to integrate Fast Ethernet segments into an existing Ethernet network.

Fast Ethernet - When and Where You Need It
Enabling your network for high-speed bandwidth needn't involve a mammoth undertaking accomplished all at once. Fast Ethernet is an extensible networking solution that can be deployed in a flexible manner, step-by-step, as your network growth warrants. A phased approach is almost always the most cost-effective way to implement a network strategy. Fast Ethernet, as an evolutionary extension of time-proven Ethernet technology, can be integrated one step at a time, when and where it's needed.

I though fast ethernet was just meaning 100megabit, like ethernet is only 10megabit. Not sure what they call gigabit ethernet.

It's just Gigabit Ethernet as far as I've ever seen.

Well, there ya go.

802.3u, 802.12, and the defunct 100VG AnyLan have all been known as Fast Ethernet over the years. Some tutorials and specs have even dubbed 802.3z/802.3ab and 802.3ae as Fast Ethernet.

In reality, the term Fast Ethernet seems to change depending on what company or standards body you are referencing.

Thanks alot everyone!
