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.

How to resolve a network bottleneck

Asked by b_lick in Network Design & Methodology, Miscellaneous Networking, Network Switches & Hubs

Tags: Network Bottleneck, switches, one port

Hey there,
I am having a bottlenecking issue with the way my network is set up. I am hoping for some advice and clarification on a couple things.
The network is setup like this.
D-Marc
Modem
Firewall
8 port Gigabit Switch.
Connected to this 8 port switch is:
our SBS server
1 16 port switch for a smaller network that does not access the sbs server
1 24 port switch that is located 250 ft away.
Connected to the one 24 port switch is another 24 port switch. So two 24 port switches connected in sequence.
Most of the bandwidth is being used by the two 24 port switches located at the front of the building and this is where I am having a bottleneck.

Mainly the only data that is being used is standard email, internet access, and file server access (all files are stored on the server). There is some larger files being transferred by graphics design and sometimes uploaded to FTP servers.

There is about 35 users with internet access. Is this bottleneck expected with this type of setup?
I am thinking my best option would to be running another cable from the server room 250ft up to the front wiring closet and connect both 24 port switches directly to the 8 port switch. Should this resolve the bottleneck?

I realize that the two 24 port switches should not be connected in sequence but it's the only option with the wiring available. Would i better off to put in another switch in the front closet and connected the two 24 port switches to a new gigabit switch?

Any other options to improve the bottleneck?

I have attached a photo.. Hi-Res to better show the setup.

Incase it helps Cisco PIX firewall,
Linksys 8 port managed switch
Dlink 16 and 24 unmanaged Gbps switches.
and Cat5e cable all around.

Your advice is appreciated!
