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

15 April 2018 4

▪ 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

  • nal «mapping

ing funct ction»

  • n» is

required to translate between Network Slices and Network Services and interact with the NFVO

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)

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

slide-11
SLIDE 11

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

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
