        •       Welcome, Agenda Bashing, Minutes taker, Blue sheets, Status -
        Chairs (10 min) ◦       Administrivia ◦       Progress report on
        current, finalized and new work ◦ •       Report from the interim
        meeting on Sunday - Chairs (10 min) ◦       See notes and presentations
        on the wiki ◦       Summary of the presentations including the live
        demo ◦ •       TODAY’s Presentations

        •       New draft defining the IPoC (IP over CCN) protocol: "Internet
        Protocol Tunneling over Content Centric Mobile Networks" :
        https://datatracker.ietf.org/doc/draft-white-icnrg-ipoc/ - Greg White
        (20 min) ◦       Q&A: ◦       Oran: Will you address congestion
        control and how to avoid silly windows effects in TCP ◦       Greg:
        Yes, in later slides. if you have more questions, ask then ◦      
        Thomas: Reference to Stanford NDN - can you make the addressing simpler
        because of the nesting of addresses IP/ICN ◦       Greg: support
        applications that are not aware of ICN ◦       Thomas: how about
        aggregation ◦       Greg: system supports unicast only, each client
        sends unique interests; interest aggregation is only important during
        handovers ◦       Cedric: Hard vs. soft handover? Buffering etc. ◦     
         Greg: Resending the interest from the PIT either after radio link
        break/make or via a new link in make/break ◦       Cedric: Scalability
        of solution? ◦       Greg: Network can have many Gateways, each
        supporting an IP subnet of some size (could be small or large) ◦      
        Alan: PIT time-out/ refresh time for the PIT entries? Is the protocol
        excessively chatty during idle periods? ◦       Greg: no real consensus
        on the refresh of PIT seconds; 300ms in experiments. We currently use
        min_CIT=10, so minimum 10 pkts per PIT refresh time. ◦       Alan: IP
        fragmentation? ◦       Greg: We don’t support IP fragmentation; MTU for
        IPOC is sufficient

        •       Breaking out of the Cloud: Local Trust Management and
        Rendezvous in Named Data Networking of Things? - Lixia Zhang (20 min) -
        how get a better IOT that uses less layering than the current cloud
        implementation less prone to failures and easier to use with NDN (no
        time for questions)

        •       Deployment of ICN stacks and NDN in particular by leveraging
        NFV - Guillaume Doyen (20 min) (no time for questions)

        •       Revised draft: "ICN Adaptation to LowPAN Networks (ICN LoWPAN)"

        •       Revised draft : "Enabling ICN in 3GPP's 5G NextGen Core
        Architecture" :
        https://datatracker.ietf.org/doc/draft-ravi-icnrg-5gc-icn/ - Ravi
        Ravindran (10 min) - An INC architecture embedded in 5G - ran out of
        time - last slides not presented. ◦       Q&A: no time for
        questions ◦ ◦       New draft: "Consideration on Applying ICN to Edge
        Computing" :
        https://datatracker.ietf.org/doc/draft-wang-icnrg-icn-edge/- Lei Wang
        (15 min) Combining EC and ICN and show how it helps both. ◦      
        Q&A: ◦       Dirk: a quick reaction from the people doing edge and
        ICN? ◦       Eve: Yes! ◦       Luca: What are the definitions on ICN
        and edge in the draft? ◦       Lei: Edge can be wifi can be anything. ◦
              Luca: But for ICN is it CCNx, NDN, other? ◦       Lei: Broad for
        now next steps will be more detailed

        •       Revised draft: "Native Deployment of ICN in LTE, 4G Mobile

        Stolic (10 min) Lab trials in next steps. ◦       Q&A: ◦       Eve:
