Hands On Projects 2-1

1. Access the Internet and navigate to http://standards.ieee.org/ The IEEE standards AssociationHome Page appears.

2. On the navigation bar near the upper-right side of the screen, click the PROJECT SEARCHlink. The information database – IEEE Standards Status Web Page appears. This one is set up alittle differnet now.. there is like a widget thing on the home page that has a search option forstandards.

3. In the text box below the search for prompt , type Ethernet, then click the search button.

4. Note the number of abstracts your search returned. For those abstracts that give designationnumbers(ie 802.3av), note the numbers as well. It says that about 63 results found... some of the designation numbers are 802.3.1-2011,802.3-2008, 802.3-REVam-2005, 802.1H—1995, 802.3bg-2011, 802.3bc-2009, 802.3ap-2007, 802.3ah-2004, 802.3ak-2004, 802.3-2000, 802.3av-2009, 802.3ba-2010, 802.3an-2006, 802.3aa-1998, 802.10f-1993, 802.3-1985/* there is a whole lot to this question imcoming baqck to it its driving me crazy just typing these numbers over and over again */ 

5. What was the revision date of the most recent standard beginning with 802.3 ? why do yousuppose this standard would be updated frequently ? 802.3 is the standard for Ethernet, the

most common type of network cable that I know of. This being used all the time and its wideacceptance calls for frequent updates of the standards for improvements etc. the most recentupdate was in 2011.

6. if you were to click on the standards returned by this search, you would need to enter alogon id and a password to read that standard. However, IEEE 's 802 (LAN?MAN)committee has made available its archives at no cost. To access the free online standards,point your browser to the following web pagehttp://standards.ieee.org/getieee802/portfolio.html The Get IEEE 802 portfolio of IEEEstandards Web Page Appears …

7. The list of IEEE 802 committee standards should look familiar to you. Click the link for802.3 called CSMA/CD Access Method ( This is the method of sharing a single channelthat devices use on an ethernet network , Chapter 5) The IEEE-SA GET IEEE 802.3LAN?MAN CSMA/CD Access Method Web Page Appears.

OK... I ACCEP T ALREADY !!9. WOW THIS FILE IS BIG... 671 PAGES... O MAN10. ETC ETCETC ETC /* IF THIS WERE C WE WOULD BE COMMENTING... ARE THEIR ANY

MATH PROBLEMS WE CAN DO FOR THIS CLASS ? */ 12. Suppose you want to know the maximum frame size for an Ethernet 802.3 frame To

find this information in the standard , click the small Search Icon binoculars in the Acrobat taskbar... 4.2.3.3  4.2.3.3 Minimum frame sizeThe CSMA/CD Media Access mechanism requires that a minimum frame length of minFrameSizebits be transmitted. If frameSize is less than minFrameSize, then the CSMA/CD MAC sublayer shallappend extra bits in units of octets (Pad), after the end of the MAC Client Data field but prior tocalculating and append-ing the FCS (if not provided by the MAC client). The number of extra bits shall be sufficient to ensure that the frame, from the DA field through the FCS field inclusive, is at least minFrameSize bits. If the FCS is 68 Copyright © 2008 IEEE. All rights reserved.

 IEEE Std 802.3-2008CSMA/CD(optionally) provided by the MAC client, the Pad shall also be provided by the MAC client. Thecontent of the Pad is unspecified.

ok... that's what I found...

13. In the “What word or phrase would you like to search for ? “ etc.. etc above..Next part 13 which is the parameter that indicates the minimum length for an ethernet frame.

Minimum size 64 octets so 64 bytes 64 x 8 bits = 512 bitsmaximum size 1518 octets so 1518 bytes x 8 bits = 12144 bits
