I tested WAN circuit bandwidth from a central site to two remote locations by using FTP test. WAN circuits to both remote locations have the same bandwidth. WAN circuit to remote location A is being used more than WAN circuit to remote location B; however, WAN circuit to remote location A was not heavily utilized during the tests. Test results to remote location B is always better than the ones to remote location A. Nonetheless, test results from both remote locations are far less than the provider's guaranteed bandwidth. My questions are as follow:
- I believe my results are based on a test of a single TCP connection. Is there a way to test the circuit actual bandwidth?
- What is the best tool for testing circuit bandwidth?
- Why is it that my test result to remote location B is always better than test result to remote location A (Same circuit bandwidth, and same test condition)?
Any additional advise is greatly appreciated. Thank you in advance.
