2 Uncompressed UHD Video Streaming over Multiple Virtual Paths Dynamically Configured by OpenFlow/SDN switches CONTENTS Dynamic SDN for Fat Streaming Application, NTT labs/japan AL3S for Demo and Network Virtualization, Internet2 Remarks about 4K Contents, RNP/Brazil AmLight, FIU [ 2 ]

3 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?

4 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 [ 4 ] (c) Copyright: Nippon Telegraph and Telephone 2015

5 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. [ 5 ] (c) Copyright: Nippon Telegraph and Telephone 2015

11 Summary (NTT part) Trial to provide virtual network for fat applications. Ultra high definition video streaming, Huge amount data transfer between clouds. Dynamic SDN Multipath streaming for bandwidth aggregation. Path selection by SDN-NAT to use preferred/well-conditioned links. We confirmed, Construct proposed Dynamic SDN over the combination of existing NRENs. Switch global parallel path dynamically with multi-location OF-sw and NW monitoring. Future Work Virtualization calculation resources in networks connected by Dynamic-SDN. Continue evaluating Dynamic-SDN with various fat applications Please see our demo!!
