Hi All,

Below, please find the minutes from our first meeting.  I sent them to the attendees before this list was created, but I thought it would be good to send them here for archiving purposes and wider distribution.

> 
> Bandwidth Aggregation Discussion Minutes -- July 24, 2015 in Prague
> 
> Discussed use of term "bandwidth aggregation" to describe this problem space, to avoid collision with BBF use of the term "hybrid access".  While BBF discussion is DSL/LTE-specific, IETF bandwidth aggregation solutions are unlikely to be specific to DSL/LTE.
> 
> Attendees:
> Dirk Hugo from Telekom Labs -- interested in use cases
> Roland Shott -- Telekom Labs -- interested in this problem space
> Alex Petrescu -- CEA? -- MIP-based solution, but mechanisms could be used with other type of tunneling
> 	Working on solution in lab that gets high aggregate bandwidth, but no draft for that yet.
> Nicolai Leymann -- Deutsche Telekom -- have tunneling solution draft  (GRE tunneling solution + framework),
> 	spoke about bandwidth aggregation between users in multi-tenant dwellings.
> DENG Hui -- China Mobile -- has no draft, interested in problem statement
> Sri Gundavelli -- Cisco -- Deployed MIP-based solution, doesn't want one IETF solution -- different for different scenarios
> Charlie Perkins -- Huawei -- Mobility management is important part of the problem, want to learn about problem.
> ZHANG Mingui -- Huawei -- Author on GRE tunnel binding, open to other solutions
> GENG Liang -- China Mobile -- Have devices with LTE and PON uplink, methods used there might be interesting here.
> 	Has a draft on how MIF PVDs relate to bandwidth aggregation.
> Margaret Cullen -- Painless Security -- Author on GRE tunnel binding, open to other solutions
> Praveen Muley -- Alcatel/Lucent -- Have deployed solution, not in IETF draft.  Work in BBF and 3GPP and on iPhone.
> 
> List of Solutions:
> Alcatel/Lucent solution
> GRE Bonding solution
> MIP-based solution
> LISP solution
> MP-TCP solution
> IEEE, LWA or other Layer 2 bonding solution (not represented here)
> 
> Margaret:  Interested in forming mailing list to discuss this.  Produce document or wiki-page describing existing solutions and relationship between them.  Work together on different layers (encapsulation, signaling, traffic split/recombination) to come up with solution(s) that are better than existing parts.
> 
> Denghui:  Would like to see us write and IETF problem statement and document scenarios.
> 
> Alex:  How has BBF progressed since last presentation here?
> 
> Sri:  No major progress.  Only one or two companies serious about the work, not progressing quickly.
> 
> Nicolai:  Thinks that BBF people realize that most of work needed is here, in standards, not in the BBF.
> 
> Sri:  Solution space is fragmented.  BBF has not actually asked the IETF to do anything in this space.
> 
> Margaret:  IETF does not need BBF problem statement to understand this problem.  MIP solution is deployed, GRE tunnel solution is deployed.  We can do good work bringing together multiple vendor solutions into a best-of-all-parts solution.
> 
> Nikolai:  Would like to see description of different solutions, properties, differences, etc.  Much of the "magic" is in load balancing, queueing, etc.  Can we combine learning from different approaches to have a common solution?  How much should be put into protocol drafts, and how much should be implementation-specific?
> 
> Charlie/Margaret:  General discussion of what problem we are discussing and why we are here.  Not captured in notes.
> 
> Margaret:  I will make there be a mailing list for this group.
> 
> Denghui:  Who would like to work on problem statement?  Hands:  Nicolai, Gengliang, Mingui, Denghui, Sri.  Sri will start this work.
> 
> Sri/Margaret:  Agreement to use google docs to collect information on different solutions.  Margaret will start google doc ad distribute to the group.  If we want a draft of this info later, we will cut-and-paste then.
> 
> Charlie:  May be distinction between bonding two similar media (both IEEE, etc.)
> 
> Nicolai:  We should at least have a Bar BOF at the next IETF.  General agreement.
> 
> Goals for next IETF:
> - Form mailing list 
> - Hold a better/earlier-organized bar BOF, at least (maybe a real BOF, if we have enough to share)
> - Have a first draft of the problem statement
> - Collect information about all solutions in a Google doc
