Other example: 5GinFire

5GinFIRE Reference Model Architecture

• Based on existing Open Source projects– e.g. Openstack, Opendaylight

• Based on ETSI reference architecture of MANO functionality – Open Source MANO

• Introducing and integrating infrastructures from verticals

• Generalizing the concept of VNFs into accounting for functionalities other than network, namely, for verticals, aka VxFs– universal management of virtual

functions

• Automated deployment of VxFsand creation of VxF stores

Ongoing - Two main verticals

addressed• Transportation

• Use Case 1: Critical and safe communications for Railway signaling

• Use Case 2: Non-critical and safe communications for Railway signaling

• Energy

• Use Case 1: Monitoring and Maintenance of Power Substations

• Use Case 2: Critical signaling and data exchange across smart metering

Use Case 2: Critical signaling and data exchange across smart metering infrastructure• Last Gasp information reads transmission

• Device (meters and sensors) synchronization

• Dispatch of information to teams and control sensors

• Minimize duration of issue

Support Infrastructure

33

IT Datacenter• 500+ physical cores

• 7+ Terabyte of RAM

• 350+ Terabyte of storage space

• Supported by 4 Gigabit switches and 5 10Gigabit switches

• The platform is running OpenStack Cloud Platform (Ocata release)

• Orchestrated via OSM (release FOUR)

• High speed fiber optic links

• OpenFlow-enabled switching (currently with HPE, Aruba and Pica8 switches) and OpenDaylight controllers

• Access wireless testbed, composed by 24 fixed and controllable nodes located at the rooftop of IT Aveiro with a mobile robot

Innovative Vertical-orientedInterdomain CapabilitiesObjective

• Automated network service provisioning to verticals…

• …Composed by slices slices belonging to different domains

• Example

Objective• Automated network service provisioning to verticals…

• …Composed by slices slices belonging to different domains

• Example

Operator A Operator B

End to end slice


Current approach

38

Single operator handles inter-domain slicing and stitching on behalf of the vertical

- Vertical Slicer entity


Current approach

39

Single operator handles inter-domain slicing and stitching on behalf of the vertical

- Vertical Slicer entity

Pros:

- Simplicity for the vertical

- Leverage existing inter-operator interactions

Cons:

- Vertical is billed a final price

- Vertical has no direct saying on inter-operator details

- Vertical has no choice!


Our approach

40

Provide the vertical with simple, yet powerful, means to select service provisioning from different domains and stitch them

Network Slice

Sub-slice A Sub-slice B


Our approach

41


• Split the VS into

• CSMF

• NSMF

• Vertical has a CSMF

• Purchased from a telco manufacturer

• It interfaces with the operators

NSMF


Our approach

42


• Current challenges

• NSMF Location Discovery

• SLA dissemination from vertical to the

operators

• Slice stitching

Important aspects

• 5G – besides NR – will rely heavily in SDN, NFV and overall

cloud concepts, as the only way to support multiple

verticals

• This core is a technology that promises to address a large

set of problems, presenting cost effective solutions for

multiplexing at different layers, and to integrate different

vertical models.

• Large-scale solutions in open environments require still a

large set of developments both at fundamental concepts

and in standardization

(non) Conclusions

• 5G is a work in progress– We even do not need to talk about 6G

for that

• Promises, promises….– For verticals, for telcos…

– Still unfulfilled

• Work ahead– In all areas!
