---------------

* Roll Call  (bh526r, 13:00:38)
  * Bin Hu  (bh526r, 13:01:08)
  * Mark Shostak  (bh526r, 13:01:16)
  * Mike Fix  (bh526r, 13:01:30)
  * Dan Xu  (bh526r, 13:01:36)
  * Trevor Cooper  (trevor_intel, 13:01:56)
  * Rose  (bh526r, 13:02:11)
  * Guangzhi Yang  (bh526r, 13:02:26)
  * Greeky2  (bh526r, 13:02:40)
  * Daniel Balsiger  (bh526r, 13:02:55)

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

* AOB  (bh526r, 13:52:54)
  * Trevor will share slides with Bin, and Bin will put it into minutes
    on wiki  (bh526r, 13:53:17)
  * 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  (bh526r, 13:53:57)
  * Meeting adjourned  (bh526r, 13:54:08)



Meeting ended at 13:54:12 UTC.
