00:06 so we're here to talk about openran
00:07 this is a big topic with lots of
00:09 potential i'm here with uh constantine
00:10 from juniper networks
00:12 constantine great to see you why is
00:14 juniper
00:15 active in openran hi gabriele good to
00:17 see you too
00:18 um that's a good question well juniper
00:21 has been a leader in high performance
00:23 performance networking uh focusing on
00:26 delivering sla
00:27 in very complex networking environments
00:30 now in the world of 5g
00:31 now we have a new opportunity to really
00:33 stretch the sla
00:34 and the slos across the infrastructure
00:37 in a
00:38 immense infrastructure highly
00:40 distributed infrastructure
00:41 all the way through the airwaves to the
00:43 devices right
00:44 whether these are iot devices or
00:47 smartphones
00:48 smart cars whatever and oren
00:51 gives us that opportunity because with
00:54 the disaggregation the software driven
00:57 radio think of the radio intelligent
01:00 controller
01:01 as the operating system of the of the
01:03 run
01:05 this is a green field opportunity i
01:08 believe that
01:09 with the moves that juniper did with
01:11 acquisition of natsia perhaps the most
01:14 innovative solution of the radio
01:16 intelligent control in the market today
01:19 we are now in a strong position to
01:21 really bring
01:22 the innovations that juniper is known
01:25 for
01:26 across uh through the radio as i said
01:30 uh and deliver uh strong slash to 5g
01:33 devices
01:35 yeah i think that's a great point about
01:37 bringing across you know expertise and
01:39 knowledge from from
01:40 other domains where there's really been
01:41 a focus on performance and sla and
01:44 programmability determinism everything
01:46 like that
01:47 so this um this rick this ran
01:49 intelligent controller product
01:51 um that's a kind of key part of the oran
01:54 architecture what are you kind of
01:55 expecting that to
01:56 to deliver for for operators right
02:00 um i like to call the radio intelligent
02:03 controllers the operating system of the
02:05 new
02:05 radio disaggregated radio architecture
02:08 right and if we
02:09 think about it as such which i believe
02:12 it is
02:13 then we can start thinking about the
02:15 applications we can run
02:17 on the rig right essentially
02:22 oren specifies apis on the du side that
02:26 allows us to hook into the low level uh
02:30 mac layer scheduler and be able to
02:33 modulate
02:33 how resources over the spec over the air
02:36 are allocated to competing flows
02:39 competing users competing slices
02:42 and therefore using intelligence
02:45 real-time intelligence about
02:47 how users behave how the radio addresses
02:51 demand we can modulate resource
02:55 allocation
02:56 and deliver strong sla right so
02:59 juniper is known for its transport
03:01 networks actually
03:03 it foresaw the need to address some of
03:06 the use cases of 5g in particular
03:08 network slicing
03:10 and today juniper supports network
03:12 slicing across all of its transport
03:14 products right
03:15 so this was a natural evolution for us
03:17 to move into
03:18 a green field opportunity on the radio
03:21 and provide applications
03:22 that address everything from the
03:24 well-known zone
03:26 type of optimizations to
03:29 new capabilities in the radio that have
03:31 to do with
03:32 very fine grain smart admission control
03:37 network slice sla assurance
03:41 strong visibility you know that
03:45 allows us to hook mlai type of
03:48 applications
03:49 and provide opportunities not just to do
03:52 extreme optimization from the device
03:54 perspective from the network perspective
03:56 but also to open up opportunities for
03:59 our customers our operator customers
04:01 to monetize you know the the you know
04:04 investment they have in the radios by
04:06 offering new applications like spectrum
04:08 series
04:09 massive mime optimization and on and on
04:12 and juniper innovates and
04:16 leads in that space not just by uh
04:19 being you know the first in the in the
04:22 world of
04:23 radio access optimization through the
04:26 rig
04:26 but also in terms of some of the
04:29 applications that we're bringing to the
04:30 market
04:32 okay and these these applications these
04:34 x apps and our apps
04:35 that run on the ric platform are these
04:38 being
04:39 internally developed by juniper or you
04:41 look into partners or
04:43 you know different different put it this
04:46 way independent software vendors to come
04:48 and fulfill some of that
04:49 absolutely the success of warren depends
04:51 on
04:52 enabling operators to select the best of
04:56 breed
04:57 right so uh to that end
05:00 we have to support any type of x up or
05:03 our app
05:04 no matter where it comes from so x up
05:06 and r portability is absolutely
05:08 strategic to the success
05:10 of warren and we definitely support that
05:12 through our sdk
05:15 but we're also developing our own x apps
05:18 as well
05:20 which i think bring a significant
05:22 differentiation in the overall solution
05:24 we
05:24 uh you know we bring to the market no
05:28 yeah okay i wanted to move on to you
05:30 mentioned network slicing that's
05:32 obviously like a
05:33 key capability in 5g particularly we
05:35 think about enterprise services
05:38 um just uh to talk through a little bit
05:41 how
05:41 how the ric will help
05:45 kind of enable operators to offer
05:46 network slicing and over-the-air
05:48 uh kind of service guarantees and things
05:50 like that
05:52 right i like to use
05:55 an analogy that may sound a little
05:57 preposterous
05:58 when it comes to network slicing right
06:00 what is network slicing
06:02 it can be anything from the familiar
06:06 service training on one end of the
06:09 spectrum
06:10 to uh what i call an mvno
06:14 on top of a you know highly distributed
06:17 you know tier one operator including
06:19 public cloud so
06:21 my goal and our goal at juniper is to be
06:24 able to
06:25 programmatically declaratively bring up
06:27 an mvno
06:29 planet scale in a matter of a few hours
06:32 not months and years that's a slice
06:35 that's the other end of the spectrum
06:37 so slice covers pretty much anything
06:41 that you can think of right tenancy so
06:44 you need to have
06:45 separate uh you know different tenants
06:48 uh
06:49 you know with a strong sla per tenant in
06:51 terms of dimensioning
06:53 how many users each tenant what type of
06:56 connection
06:57 is that going to be an emv or a massive
07:01 machine to machine communication type of
07:05 slice or the familiar
07:08 ultra low latency high reliability
07:12 type of slice and everything in between
07:14 those uh
07:15 3gpp defined use cases right so a slice
07:19 can be anything and we need to address
07:20 segmentation
07:21 security and above all sla
07:25 and having the ability to do so in an
07:27 end-to-end
07:29 fashion uh is you know
07:32 uh makes the rick an absolutely
07:35 necessary component to be able to
07:36 stretch the sla to
07:38 deliver the sla over the spectrum um
07:41 so we're taking a very you know broad
07:44 view of
07:45 network slicing and as you're i'm sure
07:48 you know
07:49 uh network slicing has been deemed to be
07:51 the perhaps
07:52 the most important use case in 5g
07:57 and several analysts have attributed or
07:59 have attached
08:00 you know hundreds of billions of dollars
08:03 of monetization
08:05 that will come through the benefit of
08:07 network slicing networks
08:09 for the operators in particular
08:12 yeah yeah i mean um the we
08:15 saw a great example recently actually we
08:17 had a we had an event on openran and one
08:19 of the keynote speakers was from a
08:21 japanese operator
08:22 kddi and they showed a a proof of
08:25 concept they've been running with ram
08:27 slicing using uh
08:28 using a rick and i had a camera on um
08:32 on the front of a train running through
08:33 this really deep kind of urban canyon in
08:35 in tokyo with gantries and metal and
08:38 different moving trains on the one hand
08:40 they showed performance
08:42 you know just on best effort and it was
08:44 up and down every time you went past a
08:45 train came by the
08:47 the performance was dropping and
08:49 bursting all over the place
08:51 they ran the same line the same camera
08:53 on the same train with a with a rick
08:54 enabled
08:55 application and it was just a solid 30
08:57 megabits per second downlink you know
08:59 barely any variation just a proof of
09:02 concept but but a really interesting one
09:04 you
09:04 think what that could mean in in future
09:08 so in the o-ram we have this uh service
09:10 management and orchestration layer
09:12 um i guess what i'm interested in is how
09:14 when you talk about these slas and
09:16 and kind of supporting them end-to-end
09:19 how does the smo
09:20 tying with the wider network
09:22 orchestration picture
09:24 the smo is critical in being able to
09:27 realize to provision
09:28 a slice across across the three semantic
09:31 domains which is the radio the transport
09:33 and the core
09:34 and we have multiple incarnations of the
09:36 transport for example we have the
09:38 you know mid hall front hall backhoe
09:41 we can have multiple instances of the
09:43 core um
09:44 and of course the radio you know can be
09:47 realized
09:48 through the edge cloud a lot of the
09:49 radio components and we count there
09:52 probably in the
09:52 thousands maybe for tier one tens of
09:55 thousands of clouds you know it's clouds
09:57 that uh
09:58 host the duc etc so how do you bring
10:02 the benefit of network slicing across
10:04 such an immense infrastructure
10:06 and uh bring the locality aspect of it
10:09 because you may want to have a slice
10:11 that is local to a particular region or
10:13 it can be across the entire
10:14 infrastructure
10:16 you need to deliver the sla that ties
10:19 how the rick works with a transport to
10:22 ensure that
10:23 you know sla the latency and the
10:25 throughput are delivered across the
10:27 infrastructure
10:28 you need to be able to provision again
10:31 the core network functions to cope with
10:33 the traffic and the dimensionality of
10:35 the
10:36 of the slice so all of that comes
10:38 together
10:39 under the smo uh which is a fairly
10:42 complex problem
10:43 right and you know activity yeah across
10:47 yeah yeah fantastic i look forward to
10:48 seeing how this how this all evolves as
10:50 you know
10:50 as as juniper and your operator
10:53 customers and whole industry works
10:54 through
10:55 uh some of the challenges and puts this
10:57 to work um constantine with juniper
10:59 networks thanks very much
