13 T2 Network Architectures for Cloud Services Cloud-based services can be seen as three interdependent structures: 1. The user access network, which connects users to applications. 2. Extreme high-speed networks, which interconnect physical servers and the movement of their virtual machines (VM). 3. Mega pipe networks, interconnecting storage tiers. This Task will investigate and propose the best architecture for supporting the three interdependent structures that support a cloud-based service, including the distribution of very large scientific data. In addition, the results and findings should be supported by tests and/or demonstration cases.

14 T3 Network Architecture for Aggregating High-speed Mobile Networking This Task will research NREN and GÉANT core and access architectures in relation to how traffic should be aggregated from Wi-Fi-based hotspots and 3G/4G off-load that are provided by third parties Such architecture will have significant implications for how the network architecture is built compared to current network architectures. In addition, the results and findings should be supported by tests and/or demonstration cases.

15 T4 Single and Multi-Domain Network Research This Task will be the host for all Open Call initiatives in JRA1. The Open Calls have been defined as four sub-tasks: 1. Research clean-slate architecture, a concept that involves rethinking the fundamental assumptions and design decisions underlying current network architectures. 2. Investigation and tracking of the development of flexible optical networks, ensuring that the NREN community is aware of and ready to deploy such services. 3. Researching multi-domain optical modelling tools by developing a multi-domain optical modelling tool that is able to assist the multi-domain deployment of alien wavelengths. 4. Testing alien wavelengths over the GÉANT network and evaluate whether alien wavelengths should later be a service offered by GÉANT. Open Call

16 T1 Future Network Architectures This Task will research and propose how GÉANT and NRENs can build their future network architecture based on functionality from current and emerging network technologies ranging from Layer 0 to Layer 3, current architectural requirements and an accumulation of proposed architectures for emerging network services 1. Network Architectures for Cloud Services 2. Aggregating high-speed mobile traffic 3. Video processing 4. Higher-rate services 5. Lower latency 6. New emerging applications identified during the work process, with high impact on the network architecture evolution towards 2020.

17 Thank you Any Questions...

18 Video processing The Task will investigate the general architecture and network technologies that are best suited to supporting aggregation and access for the provision of video services. The challenge is that video cannot be reliably provided as a best-effort Internet service, especially in the aggregation and access part of the network; with a best-effort QoS, users using a variety of mobile devices struggle to achieve a reasonable video service. In addition, the Task will address the need for an adequate architecture for supporting point-to-multipoint video streaming, which is used for example during remote lectures and conferences, etc.

19 Higher-rate services With rates of 100G now available, the sub-task will investigate what the next service interface should be, or whether there should be a clean-slate service solution

20 Lower latency The sub-task will investigate how to address the stringent requirements for quality, low latency, high bandwidth, and high resiliency of such services as time sensitive data transport service High-performance services (lossless) such as high-capacity private services High-fidelity services (low latency, low-to-no jitter) Private line services that require restoration Services that require sub-50 ms protection Cloud services that require high-volume data transactions to support storage mobility Virtual machine migrations.

21 Emerging applications New emerging applications identified during the work process, with high impact on the network architecture evolution towards 2020.
