IETF 124 SAVNET Minutes

0. Chair's Slide

1.      Presenter: Lancheng Qin
Title: Source Address Validation in Intra-domain Networks: Gap Analysis, Problem Statement, and Requirements 

Lancheng: Ask for reissuing WGLC
Xueyan: Current draft reflects the consensus. Support progressing the draft.
Shengnan: The draft is fully discussed and issues addressed. Support moving forward.

2.      Presenter: Lancheng Qin
Title: Intra-domain Source Address Validation (SAVNET) Architecture

No question asked.

3.      Presenter: Mingqing Huang
Title: Updates on General Source Address Validation Capabilities

Aijun: Think the document is stable and will consider LC.

4.      Presenter: Amir Herzberg
Title: Simulations of BAR-SAV and of Different uRPF Variants

No time for question

5.      Presenter: Lancheng Qin
Title: Source Prefix Advertisement for Intra-domain SAVNET

Peter: Complex to do what you want to do. Don't think the prefix change so often today. Use configurations instead.
Lancheng: We want to automate the process.

6.      Presenter: Mingqing Huang
Title: Provider Interface SAV for Customer Cone Sources

Amir: Having some solution is important. First, some existing mechanisms should be mentioned. Second, TE caused false positive should be considered. Recommend to do some simulations. Third, May want to consider identifying topologically the ASes that are appropriate for the technique.
Igor: Another algorithm (name uncaught) is quite similar which should be looked at.
Mingqing: Will follow up offline.


7.      Presenter: Xueyan Song
Title: Path Computation Element Communication Protocol for Source Address Validation 

Lancheng: Question about use cases for intra- or inter-domain SAV or both?
Xueyan: PCE can act as a central controller. This draft it is used in inter-domain mainly but not limited to it.
Libin: How does this work meet the requirements in the inter-domain problem statement draft?
Xueyan: Requirements raised in this problem statement draft include dynamic policy update and incremental deployment. PCE as a dynamic control plane protocol can support these requirements

8.      Presenter: Lancheng Qin
Title: A Profile for Traffic Origin Authorizations (TOAs)

Amir: Is there a real scenario? Motivation should be made strong to justify the price.
Igor: BAR-SAV authors are aware of this. Easy to use TOA as a signal. Why ROA can be a threat?  
Lancheng: Please follow up with the open discussion in the mailing list.

9.      Presenter: Jing Zhao
Title: Advertisement of Multi-Sourced SAV Rules using BGP Link-State

Mingqing: This is also talked in IDR. Why bring it to SAVNET?
Jing: Just want to make sure the scenario is meaningful.
Peter: Need to go to IDR. Personally don't believe it's the right method.


10.     Presenter: Cao Qian
Title: Export of Source Address Validation (SAV) Information in IPFIX

Joel: (hat off) Is it simpler to just export the rule ID?
Qian: No mechanism to assign ID to rule. We just want to show the full content in real time.


11.     Presenter: Haiyang Zhang
Title: YANG Data Model for Intra-domain and Inter-domain Source Address Validation (SAVNET) 

Joel: (hat on) Looks like a reasonable approach but WG is not ready to adopt YANG model at this stage.
Aijun: Currently focus on architecture.
Haiyang: Just involve the basic configuration so we want the WG to adopt it.

12.     Presenter: Libin Liu
Title: The Updates on the Benchmarking Methodology for Intra-domain and Inter-domain Source Address Validation 

Ron: (hat off) Not sure what SAV mechanism will be so it's premature to talk about benchmarking. We do know SAV will rely on ACL, any benchmark on it?
Libin: For the first part of the question. This is a general benchmarking mechanism which including the existing ones but not the new ones.
