Folks, can you help me here:
Imagine I have a MPLS network, currently with:
3825 router(headquarter)--- 3xT1--MPLS
2851 router(1 branch office)--3xT1--MPLS
Now I want to evaluate how many future branch offices I can handle with this 3xT1 in my headquarter.
I will ask clients in the branch office to perform tasks from multiple client machine so that I have a chance to analyze the load, network throuhgput, peak load, etc.
Which tool(s) I should use to monitor network throughput, usage, etc? I believe I should monitor the headquarter router and circuit usage and the branch office usage as well.
