Review of draft-ietf-monami6-multiplecoa-10.txt I've reviewed this document as part of the transport area directorate's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors for their information and to allow them to address any issues raised. The authors should consider this review together with any other last-call comments they receive. Please always CC tsv-dir@xxxxxxxx if you reply to or forward this review. In general, I did not find any transport issues that need to be addressed within this document. As noted in the abstract, this document enables the use of multiple care of addresses within MIPv6. MIPv6 (and mobility in general) can have considerable impact on transport layer performance in that handovers frequently result in substantial changes in transport parameters. However, these issues are typically handled in other documents, not within the MIPv6 documents themselves. While the use of multiple CoAs may make the problem more serious, it does not appear to change the problem fundamentally in a way that would require that the issue be addressed in this document. >From a point of view of congestion control, there are situations in which faulty lower layer indications (e.g. jittery NICs) could result in a large amount of mobility-related traffic. However, these situations are not unique to multiple CoA configurations, and so addressing this potential issue is also probably not the responsibility of this document. I did not notice any potential problems with ECN functionality. |
