Monday, Afternoon Session I 1330-1530
Room Name: Grand Ballroom 1 size: 300
Attendees more than 150.
Agenda
1. Administrivia and Agenda Bash - Chair (5 minutes)
2. Existing SDN Research Group Topics (10 minutes)

2.1 Cooperating Layered Architecture for SDN 
- Cooperating Layered Architecture for SDN (Presented by Carlos Jesus Bernardos Cano)
- https://tools.ietf.org/html/draft-irtf-sdnrg-layered-sdn-01

Will: go back to NFV case figure, i didn't see this figure in the draft?
Carlos Jesus Bernardos Cano: Will be put in next version.
Parvez : why mapping actions?
Carlos Jesus Bernardos Cano: multiple options
Parvez: a example not base line.

3. Special Session: Software Defined Network Telemetry and Big Data Analytics 

3.1 Network Health Assessment Using Big Data to Perform Network Diagnosis and Predict Future Issues (15 minutes)
- Presenter: Qin Wu

3.2 Enabling DNS Big Data Applications (15 minutes)
- Presenter: Moritz Muller

[Daniel King]: how to see some link are decreasing?
[Moritz Muller]: applicable at that case. you cannot see the traffic on the platform
[Naiming]: is this just for history or help to detect the future; 
[Moritz Muller]: should be active first. 
[Danking]: Good to see the work in sdnrg, please continue using the list. 


3.3 Dynamic Network Probes on Programmable Data Plane (15 minutes)
- Presenter: Haoyu song
Presenter: Motivation:
    - lack of real-time performance telemetry (?) 
    - need for network visibility despite 'big data' problem
Presenter: SQL-like API is feasible;
Presenter: Similarities between SDN architecture and Map Reduce programming model
Presenter: Dynamic Network Probes model offers 40x improvement over static programming, in terms of latency;
Presenter: Long list of challenges (security, performance, no language/model/API);
Presenter: Related work: INT, Inband OAM, gRPC;
 
[Dirk Kutscher] scope concern: only on OAM section or the whole network; 
[Presenter]: There is number of possible use cases / applications, OAM is currently the most important. 
[Dean Bogdanovic] considerations about the data plane if setting probes.
[Presenter]: Probes are passive. Trying to avoid changing forwarding behavior;
[Daniel King]: How do you intend to publish API?
[Presenter]: OpenSource may be good. Already seeing a research. Perhaps standardization organization should help.


3.4 An Architecture of Network Artificial Intelligence(NAI) (15 minutes)
- Presenter: Zhenbin Li
- https://tools.ietf.org/html/draft-li-rtgwg-network-ai-arch-00

Presenter: General AI is 7y old. Network AI not older than 1y.
Presenter: Propose to be processed in Routing/OPS area, with BoF or new WG.
[Dean Bogdanovic]: How is this different from the goals of the ANIMA WG?
[Presenter]: there is some overlap, need to investigate, research job will belong to SDNRG, and if we find any new stuff, will consider RTG/OPS std work.

3.5 gRPC features and protocol 
- Presenter: Eric J. Anderson 
- https://tools.ietf.org/html/draft-kumar-rtgwg-grpc-protocol-00

[???]: Can you have messages that are completely independent?
[Presenter]: Yes. 
[Daniel King]: Can you give us examples where gRPC is used?
[Presenter]: gRPC usage as Network Management interface available on GitHub (refer to the presentation materials)???
Dan: put the question to mailing list as we are out of time


4. Other SDN Topics

4.1 Autonomic Slice Networking-Requirements and Reference Model (15 minutes)
- Presenter: Alex Galis
- https://tools.ietf.org/html/draft-galis-anima-autonomic-slice-networking-01

Dan: put the question to mail list as out of time

4.2 Inter-Op Progress and Considerations in Abstraction Control of Transport Network (ACTN) Architecture (15 minutes)
- Presenter: Daniele Ceccarelli 
[Kohei Shiomoto] Any standard gap detected during inter-op? 
[Presenter] Not many...
Dan: put the question to mail list as out of time

4.3 SDN Security: Trust Models, Architecture Hardening and Infrastructure Deployment (15 minutes)
- Presenter: Saurabh Chattopadhyay
Dan: like to see more SDN security , continue in mailing list.

5. SDN RG State of the Nation
- Chairs and Secretary
