About Me

I will introduce myself, and we’ll go around and learn a bit about everyone. This will be your favorite part of the class.
Course

The purpose of this course is to provide a baseline level of knowledge for success in industry and preparation for networking certifications, including the MCSA, MCSE, CNA and CCNA designations. Students are exposed to new industry topics such as Networked Attached Storage (NAS), Cable Installation and Management, as well as Fixed and Mobile WiMAX. With a focus on networking operating systems, this course provides up-to-date coverage of Microsoft Windows XP and Server 2003 technologies along with UNIX, Red Hat Linux, and Novell Netware operating systems.

Specific topic coverage includes:

• Introduction to Networks and Networking Concepts
• Network Design Essentials
• Networking Media
• Network Interface Cards
• Making Networks Work
• Network Communications and Protocols
• Network Architectures
• Simple Network Operations
• Understanding Complex Networks
• Introduction to Network Security
• Supporting a Small Business Network
• Network Administration and Support
• Enterprise and Wide Area Networks
• Solving Network Problems

Course requirements include three exams (including a comprehensive final) and a presentation to the class.

The amount of material in this field is immense and there are so many opportunities for further study. Consequently, one of the final requirements is to create a presentation covering some aspect of communications or networks that we have not covered, or to expand on a topic we have, with my permission and your choosing.

Subject to change, but this is the general idea.

Course format:

Every week will include the following sections (excluding exam weeks):

We will begin with a short (5-10 minute) review of material presented the previous week. You are expected to read the section of the book mentioned at the end of every week. I’ll discuss the topics for that week (roughly ½ hr. to 45 minutes), with you asking questions as necessary (and appropriate, hopefully).

Then I will do a real world example (marked RWE below) each week if possible so you see applications of the technology, and we will delve deeper into the details of both theory and practice. This will be an activity that you will participate in.

I will assign you appropriate RWEs , including a report to post in the discussion boards (for example, “Download PGP and encrypt a message, post it in the message board with your public key”, or “Configure a router to allow inbound FTP and Web access, and outbound web traffic. Include screenshots”).

I want to balance lectures with RWEs both in class and in your grade.
We will recap in the last 15 minutes of class, discuss what you should pick out of the homework reading, and conclude. The text book has enough information to fill 3 or 4 semesters. I will not expect you to be tested on all of it.

Exam weeks will include a longer Q&A session if needed, and no demonstration, as that will be the exam time.

Note: there will be extra material on CourseWeb and the blog, expanding upon what is taught in class (tutorials, links, interesting articles). These are to help round out your understanding, and hopefully give you more to chew on for subjects you like. Extra credit questions on exams may be culled from this material.

Chapter 14 – Solving Network ProblemsRWE: The Tale of the SQL Server NightmarePresentation week: You pick a topic that I approve before October 1st. Your presentation to the class will be 10-15 minutes, and will discuss a popular issue in networking, or a new protocol available, or a new encryption algorithm available, a theoretical product, or an application with source code you have worked on (or, another topic you get approved with me). The point of the presentation is to give you a chance to explore a networking topic in depth, and should not be a 10 minute talking head report, but a demonstration of the use of your topic (bring a laptop and do something, or have a PowerPoint with screenshots if need be). You will have to submit a 1-2 page Microsoft Word document detailing your presentation in a written form (such that someone who missed class could understand it). Extra credit can be applied here.

Review – The Quiz Show: I will script a review lecture of roughly 45 minutes with questions to you. Extra credit could be awarded to those who answer correctly. You will have time to ask me and each other questions also. Unfortunately I cannot receive extra credit, but if you can stump me, you may get some. Attendance and participation is mandatory.
15

Final Day of class: I will mark off 45 minutes for your last chance to ask questions before the final exam. I do not want to be responding to questions 45 seconds before the final starts.
This class will also have a guest lecturer and demonstration*. I am leaving this day flexible based on how the semester goes.

The final exam is scheduled for our normal class time. PLEASE NOTE: This date is known many months in advance and should be taken as scheduled. Any activities such as work schedules, vacations, trips, etc. must be planned around this date. Let me know soon if you have issues.

Class Policies

NOTE: ALL OF MY POLICIES are superseded and overrode by Pitt’s policies if in conflict.

1. I will not have questions on exams and quizzes that I have not talked about directly, or are not in the book explicitly. I will not include trick questions that are out of left field. That is not fair to you.

2. All persons are responsible for the coding of their own program and writing of their own assignments. Copying is plagiarism and will be dealt with. I do not plan on assigning programming tasks, however in projects and small homework assignments referencing and using open source code is fine. It is a good idea. If you take an open source project and attempt to crib the whole work as your own, I will be able to tell. Remember this for your other classes.

3. If you miss any exams, and I have no notice, you will receive a 0 for that exam. However, if you have a legitimate conflict with a scheduled exam, arrangements can be made to take it some other time and such arrangements MUST be made prior to the original exam date. Same for the final.

4. If you miss a day of class, it is your responsibility to obtain the notes for that day. I will have some items online, but I am not your secretary.

5. I am not planning on providing opportunities for extra credit work beyond the 5 points listed. It’s been my experience that those who ask for extra credit work haven’t even done the required work. If you have a bad grade on an assignment or exam, put your efforts towards the remaining work that must be done. High scores in later assignments and exams can offset lower scores in earlier work and I WILL take that into account if appropriate.

6. I will be taking attendance in class. Missing more than one full class is worth 2 points on your final grade. Again if there is a legitimate reason that is OK. Being tired or engrossed in EverQuest is not legitimate.

7. Everything is optional – even passing.

Introduction to SONET

2007-09-18T08:15:00.000-07:00

The Synchronous Optical NETwork (SONET) standard for fiber optic networks was developed in the mid-1980s. It remains in widespread use today. In a nutshell, SONET allows multiple technologies and vendor products to interoperate by defining standard physical network interfaces.

Check out this WiFi radio :

Sangean intros WFR-20 tabletop WiFi radio - Engadget

It's been nearly a year since we've heard from Sangean, but the company is hitting back with a swank new WiFi internet radio that's shaped a good deal like its past units. The WFR-20 offers up 'direct access to over 6,000 Internet Radio stations (and 21,242 on-demand streams) in 250 locations from 60 genres,' and you can organize your favorites in the My Stations folder. Additionally, it's designed to operate with or without a PC, and if you have a networked computer nearby with Windows Media Player, you can have 'full access to your digital media library using the UPnP Server.' Furthermore, you'll find a three-line display, four alarms, an aux input, dual five-watt speakers, and a wireless remote to boot, but there's no word on a price or release date just yet.

Slashdot: News for nerds, stuff that matters:

An example of standards organizations being used:

"If This Was a Month Ago, OOXML Would Be Over Posted by ScuttleMonkey on Monday September 03, @06:28PM from the games-of-corporate-chess dept. Microsoft Andy Updegrove writes 'Public announcements of how Participating members of ISO have voted on OOXML are now rolling in one at a time, and the trend thus far is meaningfully weighted towards 'No with comments.' By my count, there are now four announced Yes votes, with comments, two abstentions, and seven public No with comments votes for OOXML in ISO/IEC JT1. Korea has reportedly voted no as well, and I expect at least Canada, Japan and the United Kingdom to announce 'No with comments' today or tomorrow. There will be more no votes on the roster when the final results are announced in a day or two. But even if the 11 votes I know of now were the only votes, the vote would now have failed — but for the 11 countries that upgraded their status from Observer to Participating member status in the last few weeks. Without those extra 11 'P' countries, it would only require 10 votes to block OOXML from immediate approval. If most or all of those additional 'P' members vote 'yes' as expected, it will confirm suspicions that Microsoft has promoted extra votes in favor of OOXML not only within National Bodies, but within ISO itself.'"

Standards organizations

International Organization for Standardization (ISO): Probably the biggest standards organization in the world, the ISO is really a federation of standards organizations from dozens of nations. In the networking world, the ISO is best known for its OSI Reference Model.

American National Standards Institute (ANSI): ANSI is the main organization responsible for coordinating and publishing computer and information technology standards in the United States. While they are commonly thought of as developing and maintaining standards, they do neither. Instead, they oversee and accredit the organizations that actually create the standards, qualifying them as Standards Developing Organizations or SDOs. ANSI also publishes the standards documents created by the SDOs, and serves as the United States' representative to the ISO.
Information Technology Industry Council (ITIC): ITIC is a group of several dozen companies in the information technology (computer) industry. ITIC is the SDO approved by ANSI to develop and process standards related to many computer-related topics. It was formerly known as the Computer and Business Equipment Manufacturers Association (CBEMA).
Institute of Electrical and Electronics Engineers (IEEE): The IEEE (pronounced “eye-triple-ee”) is a well-known professional organization for those in the electrical or electronics fields, including computers and networking. IEEE's main claim to fame in the networking industry is the IEEE 802 Project, which encompasses many popular networking technologies including Ethernet.
Electronic Industries Alliance (EIA): The EIA is an international industry association that is best known for publishing electrical wiring and transmission standards.
