Margaret, GRE is one thing, but on top is the deliverables as outlined in the charter. In a situation like this we should first do requirements and check gaps with existing protocols to ensure we go down the right direction. Given the scope is specified as multi-operator OTT deployment we need to ensure we understand all these implications. Referring to this: Milestones • Apr 2018 Adopt WG draft for provisioning/configuration mechanism • Apr 2018 Adopt WG draft for signaling protocol • Apr 2018 Adopt WG draft(s) for tunnel encapsulation(s) • Feb 2019 WGLC on provisioning/configuration mechanism • Feb 2019 WGLC on signaling protocol • Feb 2019 WGLC on tunnel encapsulation(s) • Aug 2019 Send provisioning/configuration mechanism to the IESG • Aug 2019 Send signalling protocol to the IESG • Aug 2019 Send tunnel encapsulation(s) to the IESG On 15/09/2017, 17:25, "Margaret Cullen" <mrcullen42@gmail.com> wrote: Given the concerns about GRE and NATs, perhaps it would make sense to remove the explicit mention of GRE from the charter and add some wording about traversal of NATs and other middle boxes? Maybe something along these lines? OLD: The Bandwidth Aggregation solutions developed in this group will be designed to work in multi-provider scenarios (i.e. they will not depend on all of the aggregated links being provided by a single Internet access provider). NEW: The Bandwidth Aggregation solutions developed in this group will be designed to work in multi-provider scenarios (i.e. they will not depend on all of the aggregated links being provided by a single Internet access provider, and they will be designed to work across NATs and other middle boxes, as needed). OLD: Select (and extend, if necessary) an existing tunneling encapsulation (e.g. GRE) for sending traffic between BANANA Boxes. NEW: Select (and extend, if necessary) an existing tunneling encapsulation for sending traffic between BANANA boxes. Do people think these changes would be an improvement to the existing charter text? If there are no objections over the next few days, I will make these changes to the online charter text.

The first thing that should happen is look at the requirements and more importantly look at the algorithms we would need to accommodate these requirements. After do gap analysis for the existing protocols and then define the potential extensions.
