EdgeHaulTM System Architecture

EdgeHaul is a centrally controlled multi-hop mesh network of mmWavebackhaul nodes

Clusters of initially ~10 nodes each areconnected by mesh to Gateway

System scales by replicating clusters

Key System Components

EdgeHaul nodes contain virtual switch(OpenVSwitch) and mmWave MAC/PHY/RF air

interface

Mesh Controller Software built on SDNframework (OpenDayLight) for flexibility

O&M Software run on cloud server with a web-based interface for remote O&M

The 5G Integrated Fronthaul/Backhaul

*TM Tec

The Context

The drivers: An ambitious set of 5G KPIs (e.g. capacity, latencat a time network operators are challenged to reduce cost

expand their service offer!

SDN, NFV and the Cloud are instrumental tools to help opetheir 5G network requirements.

However, these tools cannot be deployed independently,jointly in an optimized way to meet the 5G network infrastru

at a given time and in a given service area.

The transport network (interconnecting the access and the cpart of the overall network infrastructure, and hence shall ewith the access and the core to meet the 5G requirements.

The Challenges

High level ofdensification foreseen in 5G, raises the challenge ofsmallwhere fiber-like capacity over wireless is needed.

Macro backhaul is (carrier-grade) packet-switching and embracing theconcepts to lower costs and improve flexibility.

Fronthaul is evolving too, from fixed and costly CPRI PTP links to Etherfor scalability and lower cost, but not yet resolving the challenges of blatency.

The RAN is embracing virtualization too, with new functional splitrelaxing the bandwidth requirement of CPRI (and CPRI-like) fronthaulthe latency.

This calls for a unifying transport solution that integrates the fronthautraffic mixture, in a common-haul packet switching under a common-hacontrol. This is the aim of the 5G-Crosshaul project!

RAN Function Splits Challenge

Centralization of RAN functionsyield benefits from hardware

consolidation and advanced signalprocessing (e.g. COMP)

Cost and availability of transport(e.g. fiber) may prohibit fullcentralizations

Example Motivation for Unifying Transp Diverse data transport systems exist at

network edge, especially for indoorwireless

Limitations No common management system

No flexibility for evolving network architecture

MEC in 5G-Crosshaul

5G-Crosshaul project has set its focus on 5 key use cases, 3 vespeed train, media distribution, dense urban society) and 2

(multi-tenancy, and mobile edge computing).

MEC schemes are envisaged in the application plane of the 5infrastructure, with benefits to the end user (QoE) and operatmanaged backhaul capacity, service differentiation)

5G-Crosshaul focus areas on MEC use case include:

Mobile edge computing in the architecture

MEC Requirements on the NBI/SBI

Optimization of network and computing resources
