5G-TRANSFORMER Overview

5G-TRANSFORMER aims to to transform rigid id mobile transport networks in into an an SDN/NFV-based 5G Mobile Transport and and Computing Pla latform (MTP)

Technical approach:

• Enable Vertical Industries to meet their service requirements

within customized MTP slices

• Aggregate and Federate transport networking and computing

fabric, from the edge up to the core and cloud, to create and manage MTP slices throughout a federated virtualized infrastructure

5G TRANSFORMER Concept

▪ Vert rtical Sli Slicer (5 (5GT-VS)

• logical entry point for

verticals to support the creation of their transport slices in a short time-scale

▪ Se Service Orc rchestrator (5 (5GT-SO)

• federation of transport

networking and computing resources from multiple domains and allocation to slices

▪ Mobile Tra ransport and Computing Platform (5GT-MTP)

• underlying unified transport

stratum for integrated fronthaul and backhaul networks, including compute resources

From Vertical Service to Network Slice to NFV Network Service Instantiation

15 April 2018 5

Verticals, MVNOs 5GT-SO 5GT-VS Vertical Services (VSB) NFV Network Service (NSD and flavors)

Defining and Managing Vertical Services:

(1) Defining vertical services (VSB->VSD) (2) VSD/NSD translator: maps vertical’s requirements to NFV-NS NSD deployment (3) Mapping vertical services to network slices, in turn mapped to NFV Network Services

VSB->VSD->NSD Vertical Slice -> Network Slice Network Slice -> NFV Network Service NFV Network Service Instance (NFV-NSI ) 5GT-MTP

NFV Network Service Orchestration/Federation:

• Service Orchestration

(NFVO-NSO)

• Resource orchestration

(NFVO-RO)

Request resource allocation and instantiation

• Allocation of resources over

the infrastructure

• Providing abstractions

Architecture in 3GPP and ETSI NFV

15 April 2018 6

• 3GPP TR 28.801 – Architecture
• CSMF: Translates the communication

service requirements to network slice requirements

• NSMF: Manages the NSIs, including their

lifecycle and their mapping with the NSSIs that compose them

• NSSMF: Manages the NSSIs and their

lifecycle

• Map to NFV architecture
• CSMF, NSMF and NSSMF are part of the

OSS/BSS

• An additi

itiona

SO Key Functionalities

• Service

vice Orche chest strati ration

• Orchestration of E2E NFV Network services to fulfill the requirements of the

vertical services requested through the VS

• De-composition of NFV network services to multiple segments, deployed in

different technical or administrative domains

• Provisioning of E2E NFV networks service
• Resource

rce Orch chest estrat ration ion - optimum decisions on

• VNF(s) Placement
• Resource to be allocated
• Federat

ration ion with other administrative domains through EBI/WBI

• Resource federation (NFVIaaS)
• Service federation (NSaaS)

15 April 2018 9

Use case 1: NFVIaaS

15 April 2018 10

• The NFVIaaS consumer is a service

provider that wants to run VNF instances inside an NFVI provided as a service by a different administrative entity: the NFVIaaS provider

• The NFVIaaS consumer has the control of the

VNF instances and virtual resources

• NFVIaaS consumer and NFVIaaS provider

belong to different administrative domains

• The NFVI of the NFVIaaS provider is

structured in several VIMs

Use case 2: Network services over multiple administrative domains

15 April 2018 11

• Each administrative domain

includes one or more NFVI PoPs, VIMs, VNFMs and an NFVO

• Distinct specific sets of

Network Services are instantiated on each administrative domain

Hierarchical interaction between NFVOs

15 April 2018 12

• ETSI IFA 028 proposes a hierarchical architecture:
• The NFVO of the administrative domain offering the composite NS interacts

with the NFVOs of the administrative domains offering the constituent nested NSs through a new reference point, called Or-Or, based on IFA013

5G-TRANSFORMER architecture based on hierarchical paradigm

15 April 2018 13

5G-TRANSFORMER architecture based on peer-to-peer paradigm

15 April 2018 14

Federation

• Defined on the SO-SO interface for sharing of resources and/or

services

• Can be formed as
• Pre-established federation
• Relationship agreement is previously established (offline) as a business

agreement

• Open federation
• Established between entities that advertise their resources publicly
• Key difference is level of abstraction applied to

resources/services

15 April 2018 15

Conclusions

15 April 2018 16

• 5G-TRANSFORMER architecture is based on SDN-NFV
• 5GT-VS:
• Logical entry point for verticals to support the creation of vertical services
• Creation of network slicing tailored to specific needs of vertical industries
• 5GT-SO: Service/resource orchestration and federation
• 5GT-MTP: Evolved Mobile Transport and Computing Platform plus MEC
• 5G-T architecture mapping to 3GPP/ETSI NFV
• SO architecture options
• NFVIaaS
• Network services over multiple administrative domains (hierarchical and P2P)
