“Edge is the next infrastructure paradigm for delivering applications and services closer to the user. Edge allows efficient processing and delivery of time sensitive data”

“Edge refers to the geographic distribution of compute nodes in the network”

“Edge is a distributing computing paradigm in which computation is largely performed on distributed devices sitting closer to end users”

Edge is● Independent● Elastic/Optimized● Massive scale

Edge must be● Automated● Resilient● Be built using public, private or hybrid cloud

Edge is about building ultra-reliable experiences for people and objects when and where it matters

Edge is anything that sits between the Subscriber / User / Endpoint and regional or core data center

What Does Edge Mean?

Distributed RAN

http://xhaul.eu/wp-content/uploads/2015/10/workshop-FSAN-09-2015-atlanta-orange.pdf

Full base station functionality distributed on each antenna sites -> expensive, no scalability, radio interference control challenges, etc ...

BaseBand Units @ Antenna Site BaseBand Units @ Central Office (Cloud)

Part of base station functionality (BaseBand Units, BBU) centralized (base station split).

X2: “fast” handover protocol between base stationsD-RoF: Digital Radio over Fibre

Target for NFV, (virtualization or

containers) + Edge Compute
