Table. 1 - Modeling Approaches Advantages and Disadvantages

<font color="#e0121d"><b>Summary </b></font><br/><font color="#29313b"><b>Modeling Approaches Advantages and Disadvantages</b></font><br/><font color="#29313b">Each modeling approach presented in this addendum has its own advantages and disadvantages as shown in the table below.</font><br/><font color="#29313b"><b>Conclusions </b></font><br/><font color="#29313b">The choice of the appropriate modeling approach is at the discretion of the SID implementer.  One approach would be to explicitly model existing IPDRs that are stable and least likely to change.  As new IPDRs are added the characteristic specification approach can be used to reduce the implementation time.  These could then be explicitly modeled once the IPDR matures and stabilizes.</font><br/>
