Introduction

• Research Goal

– Provide virtual network for fat applications

• Uncompressed 4K video needs at least 7 Gbps bandwidth. (30 frames per sec)

• Still tough to transmit them without IP packet losses.

• Background

– 100 Gbps ultra-high-speed IP networks have become familiar in NRENs.

– Shared networks are suitable for temporal use of users, but fickle.

– SDN technologies are being deployed in every networks.

• Problems

– How to secure the bandwidth required for “fat” applications like >7Gbps streaming?

– How to secure the condition of the data path continuously against congestions,

malfunctions & maintenances?

Dynamic SDN

Solution for Fat Applications using boroadband networks Anytime & Anywhere

• Build as “Overlay Network” on existing shared L3 and/or L2 networks with

multiple paths

• Defined dynamically

• Provides QoS (ex. bandwidth) required by “Application”

Dynamic SDN for Fat Applications

Network Address Translation (NAT) based overlay SDN technology.

• Multiple Path Streaming

– Carefully finding the preferred links from well-conditioned paths in shared IP networks.

– Aggregate them and virtualized into single link for the 4K streaming.

• SDN-NAT: Path Control by OpenFlow Switches on Nodes

– Routing control by changing the destination addresses of data-flows.

– Free from tagging-based (VLAN/MPLS), capsuling-based (IP-SEC/PPTP) path control.

– No IP packet loss in transition of routing reconfiguration.

• Continuous Networks Monitoring

– Initial selection of links.

– Detect the degradation of the link conditions to replace.

Lesson Learned in SC14

• Switch global path with SDN-NAT monitored traffic data

– Trial in global, multi-domain multi domain connection of NRENs.

– Alternative receive & display at SC14 venue.

– Various video format of HD (~1.5Gbps)
