Intro & Motivation

• Cloud Computing

– Fast Emergence

• Research, industries and standardizations

– Enables ubiquitous and on-demand access to shared resources – Large scale applications become feasible

• Big data, HPC..

– Single central point Scalability & Availability issues

• Distributed Clouds

– Decentralized management – Resources distributed in several geo area – “Volunteer” clouds

• An example: VIFIB

VIFIB Distributed Clouds

• VIFIB: Resilient Computing

– No data center architecture:

• Micro servers located in homes, offices..
• Distributed resources More Availability: 99.99%!

– Master/Slave architecture – Resiliency

• Data is encrypted and replicated

in different locations

• Overlay Network of

Open VPN tunnels (re6st)

Re6st: Resilient Overlay Networking System

• Re6st

– Mesh network of Open VPN

• Flat and random graph

– Babel Protocol used to calculate best routes – Fast recovery!

• Issues with Re6st

– Security issues

• Bad routes flooding

– Scalability issues

• Flat topology does not scale
• Tunnels might consume

extensive resources

RINA: Recursive InterNetwork Architecture

07/10/2015 NOF 2015 6

• Inter-Process Communication (IPC) model
• Unlike TCP/IP, one single layer
• that could be

repeated recursively

• Clean separation

between mechanism and policy

• Divide and Conquer
• Scalability

• The distributed clouds is divided into groups
• Group leaders are created to interconnect nodes from

different groups and to form the inter groups

• To support scalability, multiple levels could be created

Conclusion

• SFR: new and generic routing architecture for distributed

clouds

– Hierarchical DIF architecture

• SFR achieves better results compared to current distributed

clouds networking solutions

– The forwarding table size is drastically decreased

• In future works, we plan

– Further evaluate the assets of applying RINA to distributed clouds

• Consider more evaluation metrics: latency, throughput..

– Deploy SFR within VIFIB infrastructure to compare it to re6st
