We have modified the charter after Prague and the June interim meeting. Item2 in scope: Identify potential benefits to these networks from innetwork functionality, including but not limited to compute, cache, manage, control, etc. Item3: Research on novel architectures, data-plane abstractions and new network/transport protocol designs Item4: Research on potential new transport protocol, new privacy and security mechanisms required or enabled by in-network compute. COINRG Milestones Dec 2019 (post 106) Articulate COIN challenges Related drafts: draft-kutscher-coinrg-dir, draft-liu-coinrg-requirement Capture the SoTA of the COIN landscape Related draft: draft-kutscher-coinrg-dir Apr 2020 Target COIN case studies, from architecture, implementation and use case standpoints Related drafts: draft-he-coin-managed-networks, draft-kunze-coin-industrial-use-cases, draftmontpetit-coin-xr

Identify COIN network-related eco-system dependencies Related drafts: draft-mcbride-edge-data-discovery-overview Discuss/catalog COIN requirements and implications for network elements (including network services, network SW stacks, network HW design, etc.) Related drafts: draft-mcbride-edge-data-discovery-overview , draft-he-coin-managednetworks , draft-kunze-coin-industrial-use-cases Nov 2020 Work toward defining a COIN scope appropriate for the IRTF, within which new architectures, mechanisms and protocols can be proposed 6 Existing IDs New Drafts: draft-kunze-coin-industrial-use-cases-00 draft-kutscher-coinrg-dir-00 draft-liu-coinrg-requirement-00

Emile Stephan, Orange Diego Lopez, Telefonica Andrew Alston, Liquid Telecom Sara Al-Kokhon, U. Toronto Thomas Sheffler, Hochschule fr Technik und Wirtschaft Berlin Rmi Pellan, Pierre-Louis CaronAuger and Marc Leclerc, Noviflow COIN co-chairs Jeffrey He, Huawei Eve Schooler, Intel Marie-Jos Montpetit, MIT Hemant Singh (remote) Invaluable support from Noviflow P4 experts Pierre-Louis & Rmi!!! Thank you! 8 Hackathon Summary (2) What we did: Basic examples to get everyone onboard IPV6 Switch ML from the remote participant Relates to Scaling Distributed Machine Learning with In-Network Aggregation (IPv4)

p4-16 code checked into repo: There is a discussion on the list about this work P4 to Golang Packet Filtering Store a packet compare any new packet to this one and an action is performed Link to alerting, ML, decision systems Ideas gathering for future projects (picture to be uploaded) What we learned: The need to come prepared (VMs install/config take time) The usefulness of experts in a field still expanding You can get participants the same day You do a lot in 2 days The teamwork is great! Next Hackathon: Singapore now that the team is well organised!

9 Presentations Instructions to presenters: please try to link your work to the charter and highlight where changes are necessary! 10 Next Meetings Virtual interim meeting in October 7 (date TBD in e-mail poll) to address the charter and first set of milestones Meet at IETF 106 in Singapore (November 16-22) 11
