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!

more ICMP packets than http packets

Asked by jemal93 in Miscellaneous Networking, Network Switches & Hubs, Network Auditing Software

Tags: packet, block, icmp_unreachable

Hello everybody! this is my favourite place to get expert assistance. So i have come up with a question.
I work for an ISP(about 10K customers). The problem we face more frequently is that there are more ICMP packets coming from the customer premise. With the outbreak of the blaster worm this was dealt by applying worm removal tools on the customer device and by blocking the tcp ports that the worm uses.
But the more and more customers are facing network congestion due to this. When we use the "sh ip nbar protocol-discovery" command on our distribution routers, most of the packets are ICMP packets..
So what I want to know is that what can be judged about the customer device if more ICMP packets flow into our routers??
