Addendum

Some of the Web sites have changes or have been removed from the Internet. If you canít get to a site, go to a search engine like www.altavista.com and search for the name of the site given in the book.

Figure V-2 on page 1030 is incorrect. You can view an entire update for the topic with new pictures by going to the following Web site:
L2TP and Modems.

One of my favorite sites, Prof. Jeff MacKie-Masonís Telecom links has moved. Change the link on page 1114 to http://china.si.umich.edu/telecom/telecom-info.html, then add it to your Web browser favorites. Here are two other good sites for linking to all sorts of networking technologies:

http://www.hojmark.org/networking.html

http://rtlab.kaist.ac.kr/~sikang/soho/soho.html#soho

Other changes:

Page 900: the year 1977 in the second paragraph should be 1997.

Page 852: the last line (related to the bullet list on the next page) should read:

"The following information is used to set the metrics that the Dijkstra algorithm uses to calculate the shortest path."

Here is some additional information on this topic:

Note that automatic cost settings are usually based on bandwidth (or the cost is set to a default value), which may not be appropriate for some links, so administrators should closely evaluate links costs in order to obtain the most accurate path calculations."

 

How to copy pictures:

To copy text, you first highlight the text you want by dragging through it with the mouse. Then you choose Copy Selection from the Edit menu. But if a picture is included in the selection, it is not copied with the text. You must copy pictures in a separate step as follows. First, click the figure to open it in an expanded window. Now press Alt+PrintScreen to capture the figure onto the Clipboard. Next, paste it into another document by clicking at the position where you want to paste and then pressing Ctrl+V to paste it.

Tip: If you make the Encyclopedia of Networking window full-screen before you capture an image, the image you capture will be much larger.
