Primary goals of OF@TEIN+:
1. Gather and Learn Together: Expanding the OF@TEIN Community and Sharing the Knowledge about Open and Federated (i.e., shared) SDN/NFV/Cloud-integrated Playground amongst the Members.
2. Build and Upgrade Together: Deployment and Upgrade of Open/Federated Playground with Distributed SmartX Box Playground Resources and Centralized Data Lake/Analytics Hardware.
3. Operate and Automate Together: Collaborate among Leading Members to enable Automated DevOps-style Operation of Playground Resources and Platforms.
4. Play and Visualize Together: Collaborate with All Members in Experimenting (i.e., Playing) and Visualizing “Plays over Playground”.
5. Investigate and Enrich Together: Investigate selected building-block topics on Future Network technology and attempt to enhance the playground capability/agility by applying the investigation outcomes.

Different Levels of Federation toward Building Open Federated Playground
▪ Resources Federation is a concept to share resources beyond the administrative domain where at least one resource manager is associated with more than one physical resources for providing a logical aggregate view of all resources of the federation.
▪ Workload Federation/Federation of Workload is an illustration of resultant topology between all the users service request with specific service level agreement (SLA) and providers resource provisioning results in optimistic resources reservation scheme.
▪ ID Federation is a set of agreements, standards and technologies which enable users to use their digital identities and attributes to access group of services within a federated domain regardless of organizational borders.
▪ Federated Playground is a group of open playgrounds whose owners choose freely to share resources across their user communities, according to mutually agreed rules and limits, and it intentionally to implement an open resource hardware with open source software and shareable set of configurations.

Multi-tenant Network Slicing Technique over SDN MPLS Networks
17
MULTI-TENANT USING SAME IP SPACE
Challenge:
Design
▪ Proposed Idea
• Utilize existing MPLS as slicing technique
• Larger label size (20 bits) available
▪ Proposed Method
• Every tenant hosts are assigned a unique MPLS label at the network edge
• Construction of Label Switched Paths (LSP) for end-to-end communication
• Labels are distributed throughout the network by SDN controller, intermediate switches act as “Label Switched Routers (LSR)”
LSP Construction Method
The SDN Controller…1. Register host per switch port per tenant .
2. Maintains a Virtual Routing and Forwarding Table (VRF) per
tenant for the network.
3. End-to-end path computation for all possible paths between
tenant hosts.
4. Optimum path selection.
5. Distributes label along selected path switches

For Tenant A• Register A1 and A2 ports with IP info to VRF Tenant A on controller• Connection SW1:F1 – SW2:F2 and SW2:F0 – SW2:F0 are multi-tenant
ports (non-registration active ports)• Path computation and path selection per tenant by controller when
needed• Labels assignment and distribution by controller
