13:04:11 <bh526r> #topic Continue Discussion on How to Support CNTT in OPNFV
13:05:02 <bh526r> #info Trevor Cooper prepared a few slides of NFVI Infrastructure Abstraction
13:06:07 <bh526r> #info It covers (1) Abstract NFVI from VNFs (2) Define Standard Capabilities and Metrics (3) Define Infrastructure Profiles
13:06:36 <bh526r> #info Cedric Ollivier
13:06:53 <bh526r> #info Rex Lee
13:07:53 <bh526r> #info and the rationale why we need the abstraction and profiles
13:08:29 <bh526r> #info Trevor Cooper then introduced details of Infrastructure Profiles Catalogue
13:09:20 <bh526r> #info Then different types of VNFs (from ETSI specs)
13:09:52 <bh526r> #info 3 VNF categories are described
13:10:17 <bh526r> #info Those are Basic, Network Intensive and Compute Intensive
13:11:01 <bh526r> #info Network-intensive needs high throughput and low latency requirements of handling network traffic
13:11:56 <bh526r> #info Then Trevor Cooper described layers of instance types
13:12:45 <bh526r> #info i.e Profiles -> Options (compute options and virtual interface options) -> Extensions
13:13:07 <bh526r> #info Georg Kunz
13:13:14 <bh526r> #info Manuel Buil
13:13:46 <bh526r> #info Murtuza Khan
13:15:57 <bh526r> #info Compute Option Metrics are introduced as an example, such as number of vCPUs (e.g. 16), size of RAM (e.g. 2GB), size of local disk (e.g. 160GB), and bandwidth of management interface (e.g. 1 Gbps)
13:16:33 <bh526r> #info And an AWS instance example
13:17:10 <bh526r> #info George Yang
13:19:57 <bh526r> #info Then Trevor Cooper gave an example of vendor-defined spec for compute option for a network-intensive hardware profile
13:25:19 <bh526r> #info Trevor clarified that hardware vendor should give input to hardware specifications
13:26:28 <bh526r> #info Mark Shostak indicates that in CNTT spec, there is hardware profiles to capture hardware capabilities and metrics.
13:26:54 <bh526r> #info It is very close to what Trevor introduced here
13:27:33 <bh526r> #info Trevor agreed that it is about how to specify hardware profile in CNTT as well
13:28:02 <bh526r> #info Mark asked if it is for capability or for performance
13:28:20 <bh526r> #info Trevor clarified that it means both capability and performance
13:28:41 <bh526r> #info Mark wanted to separate capability from performance
13:29:46 <bh526r> #info Trevor indicated that we cannot completely separate capability from performance, either absolute performance or relative performance
13:30:59 <bh526r> ##info Mark said it is a level of compromise what to put in abstract level and what to put in more specific level
13:33:29 <bh526r> #undo
13:33:29 <collabot`> Removing item from minutes: <MeetBot.ircmeeting.items.Info object at 0x1e81e10>
13:33:51 <bh526r> #info Mark said it is a level of compromise what to put in abstract level and what to put in more specific level
13:35:39 <bh526r> #info Mark said that he owns the chapter of hardware profile in CNTT spec. He can put it on the agenda and Trevor can give input to the chapter
13:36:01 <bh526r> #info Trevor said there is another aspect of benchmarks
13:38:27 <bh526r> #info Sunku Ranganath
13:41:34 <bh526r> #info Mark said he really liked Trevor's slides. He suggested to discuss it in more details on Wednesday's CNTT call.
13:42:40 <bh526r> #info Mike Fix and Mark S asked for a copy of slides
13:44:09 <bh526r> #info Mike thinks it is very good, and he would like to incorporate some into Chapter 8
13:44:31 <bh526r> #info Trevor will email Bin the slides, and put into minutes on wiki
13:45:50 <bh526r> #info George Yang asked that on page 7 and page 6, if specified in Intel CPU, it may not be applicable to ARM
13:46:42 <bh526r> #info Trevor clarified that it is really up to manufacturer to decide what they think to meet the profile.
13:47:17 <bh526r> #info The spec will not say what to buy to meet the profile. Spec is just a guidance
13:52:54 <bh526r> #topic AOB
13:53:17 <bh526r> #info Trevor will share slides with Bin, and Bin will put it into minutes on wiki
13:53:57 <bh526r> #info Mark will put it into CNTT agenda, and Trevor will present it in CNTT meeting. Important is to have enough time for Trevor to go over the details of proposal
13:54:08 <bh526r> #info Meeting adjourned
