Below are my questions:
1. How to determine the acceptable latency, througput in accessing an application over a WAN infrastructure?
2.How to set threshold for a certain application traversing WAN that is accessed by multiple users?
3.In capacity planning, what is the best thing to consider to anticipate network degrade?
4. What are the causes of these delays data or voice?
Any reading materials, white papers, documents you can share, appreciate that.
If you know of application performance or network tools that is best used in the market today, kindly share it to me. thanks,
