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!

computer Networking (TCP segment question)

I have these two questions and I don't know how to answer them:
-Suppose that a TCP segment has a lifetime of 2 minutes in the network. Calculate the maximum transmission speed (bits/second) at which a host can send out 1460-byte, TCP segments so that there will not be two TCP segments from the same sender with the same sequence number in the network, i.e., without having the TCP sequence numbers wrap around?
-calculate the maximum payload size (i.e., data portion) of a TCP segment given that the network layer (i.e., IP layer) datagram has a minimum 20 bytes of header and the maximum length of an IP datagram can be up to (2^16) - 1 bytes.

Is this a homework question, it sounds like one.  If so you should have the question closed as that is not what this site is for.
 
02.26.2008 at 07:50AM PST, ID: 20985352
yes it's a homework question but I don't know how to get the answer I need someone to explain to me how to do it!

I'm sorry but you will find very few experts who will answer homework questions...

I'm sure the answer is in your book somewhere

I couldn' find it any where in the book, I already submitted the HW but don't understand how to calculate these, and I can't understand the instructor.
 
03.02.2008 at 01:11PM PST, ID: 21027600
I found the answer for the second question:
max. Payload size = (2^16)-20-20

but I am still looking for the first question

I would prefer that you either accept your last comment as the answer or delete the question as apposed to giving me a C grade.

Please contact the site administrators and ask for assistance in what ever path you choose.
