Remote 1800 router has L2L VPN back to headquarter. The bandwidth in 1800 router is 1.5 MB. However, sometime the traffic may reach the limitation of bandwidth, and the application will be dropped.
Here are the followings we did:
1. Check the L2L- okay
2. adjust tcp mss - no improvement
3. Change the router - no improvement
We suspect the ISP may be dropping our traffic, rather than queuing it when we saturate the pipe. Understand that get more bandiwith will be the best solution.
Is it possible for us to shape and queue the traffic on the router 1800? if it does, how it works? or are there any ways to handle this issue?
