The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

What impact does a gigabit port on a switch have in a multiple-switch topology?

Asked by MadManse in Miscellaneous Networking, Network Design & Methodology, Networking Hardware

Tags: Connecting multiple switches

Assume the following simple network:

one router
three 24-port switches
70 PCs

Assuming all 70 PCs have 10/100 NICs, here are my questions:

1. If the router has only one LAN port--no matter what its speed--then I would have to daisy chain the three switches with crossover cables. This necessarily means that the PC connected to the 2nd switch would suffer some performance loss because the traffic to them would have to get through the first switch first, and PCs in connected to the 3rd switch would suffer even more.  Is this right?

2. To correct the problem, connecting the router to a new switch and connection the original 3 switches to the new one should give all PCs a fairly even response time, right?

3. Keeping in mind that a network is only as fast as its slowest device, would there be ANY performance iimpact if all router and switch ports were 10/100/1000?

Thanks in advance for your comments...
