Ok. Lets quickly review the PS document that was used for this
discussions, draft-zhang-banana-problem-statement-03.txt ("Problem
Statement: Bandwidth Aggregation for Internet Access²)

"
1. Introduction

   Use cases of BANdwidth Aggregation for interNet Access (BANANA,
   a.k.a., Hybrid Access) are described in the Technical Report [TR-348]
   published by Broadband Forum: by providing Hybrid Access, Service

³

Your use-cases are what BBF has defined per your PS. I assumed its clearly
about DSL + LTE aggregation, that is driving this work. Now, if the
argument is we need DSL + SATRAN, please point me to one RG that has
support for DSL and Satellite, or a deployment where an RG uses Wi-Fi as a
WAN link. Sure, I also saw the comment from Margaret that "one person on
this thread mentioned wanted to aggregate two WiFi links, another person
has talked about aggregating VPN links².  I wonder, if we have we made it
so easy that we can create IETG WG¹s so easily, based on such individual
wishes, with no details on how and where its used. Its well understood
that link-aggregation has value and nothing new there. But, please present
very specific use-cases beyond BBF use-case.





Regards
Sri
