Todo List
 Section 8.2 needs to be pared down to the right level of detail to
be consistent with the rest of the doc [Done]
 Section on capabilities [Done]
 We need to look into section 9 further. It seems very sspm-
oriented. [Nearly done]
 Section on control tables [In Progress]
 The diagram really needs more work. [In Progress]
 Address whether we should add common usage examples and
rename the doc to something like "Introduction to the RMON
Family of MIBs".
 Overall proofreading, etc.

 Metric Layers
– Application Performance Metric:
• Application Response Time
– Data-Link Performance Metric
• FCS Errors
 Application Layer Bucketization:
– FCS Errors for HTTP Traffic vs. SAP/R3 traffic
Change to 2 tables?

Scope and Title
 Should we add:
– Tips and techniques for problem solving with RMON
– common usage examples
– probe placement strategies
 Should we change the title?
– E.g., "Introduction to the RMON Family of MIBs".
