2 What can we learn from Cloud Computing? Page 2

3 How much Data is generated? Source: DOMO, data never sleeps 3.0 Page 3

4 IT Centres need a new Network Architecture in Software and Hardware Google, Microsoft, Facebook etc. broke the wave Google Net has now 1-2 Mio. servers running on SDN Microsoft just hit 1 Mio. server barrier Why? Different network part need different policies (VLAN,ACLs) Storage grid versus computing grid Data centre networks are rapidly growing: Huge scaling issues Could not scale up to bigger and bigger devices, needed to grow via continuously adding standard hardware Source: Microsoft Page 4

10 Trend in ITC: Evolution towards Open Architecture PC/Smart Phone/Server/Switches/MSAN In the past: proprietary software with the proprietary northbound interface Now: Open Architecture with Linux allowing for better customization PAST PRESENT Closed SW Closed HW Open SW Closed HW Open SW Open HW Standard, open APIs Page 10

11 KEYMILE R&D: ADDONAS Project Active Distributed & Dynamic Optical Network Access Systems Project duration: Sponsored within the Piano+ initiative (EU FP7) Consortium Poznan Supercomputing and Networking Center (PSNC) Intune Networks Belfast University of Bristol (UNIVBRIS) Compound Semiconductor Technologies Global (CSTG) KEYMILE Web page: Page 11

12 On Demand Service Provisioning Active Distributed & Dynamic Optical Network Access Systems Page 12

13 ADDONAS Goal Add Flexibility and Automation to access network Virtualization of network resources for multiple service operators Guaranteed quality of experience for end user Multiple services of any type coexisting on the same infrastructure Allows users to gain access to (any) Service Provider present in the joint metro/access architecture Allows service providers to offer services through multiple Virtual Service Operators (market-like approach) Page 13

14 Cloud Computing Architecture based on Open Software Openstack allows to manage Compute, Networking and Storage at the same time Your Applications APIs Horizon Compute Networking Storage Openstack Shared Software Services Source: Standard Hardware Page 14

16 Key Concepts Public Networks as a Cloud Service Openstack running on a control server Bare-metal switch running Cumulus Linux MileGate blade running Linux and OvS Multi-play solution HSI IPTV VoD VOIP Bare-metal Switch Switch Bare-metal MSAN MSAN Functions Control Storage CPU Bare-metal MSAN MSAN CPE CPE CPE CPE CPE CPE CPE CPE CPE CPE CPE CPE CPE CPE IPTV/Internet/VOIP IPTV/Internet/VOIP Page 16

17 Key Features Public Network as a Cloud Service Cloud-driven solution Open-Access Networks Open approach Linux-enabled network devices (no vendor lock-in) Open hardware Open standard API Community-driven OpenStack Cloud Orchestrator (easily extendible) Simplicity and rapidity of provisioning (mass-provisioning) Network automation Network topology abstraction (1 to 10k mapping) Page 17

18 Public Network as a Cloud Service: Network Abstraction Network abstraction Organized according to services Element Aggregator Aggregation of logical entities Service template Template driven provisioning Network wide profile Page 18

19 Openstack Network Topology A Network per Service A VLAN per Service High Speed Internet Voice Over Video IP on Demand Page 19

20 Open Source Adaptations in Progress Openstack Enhanced Horizon Adapted ML2 Neutron OvS driver MileGate/Linux Blade Unmodified Linux from Open Modular Packages Open vswitch (OvS) Edge-Core Core Cumulus Linux Page 20

21 Next Steps Extend Open vswitch to MSAN access subscriber units Add Interfaces xdsl FTTH Open Software Open Linux kernel drivers for above interfaces Open vswitch interworking with switching ASIC Openstack contributions Performance/Openstack scalability Acceleration engine Openstack Enhanced Platform Awareness (EPA) Neutron network driver SDN controller integration Network telemetry Page 21
