This document summarizes the OF@TEIN SDN-Cloud Playground project. It introduces the TEIN and OF@TEIN networks and describes the SmartX Box hardware and software used for the SDN-Cloud testbed deployment. Key components include OpenStack, Open vSwitch, and OpenDaylight controllers. The testbed allows for centralized management of distributed cloud resources across multiple regions. It demonstrates programmable virtual networking between clouds and datacenters using SDN and VXLAN tunneling.

4. Introduction
• TEIN (Trans-Eurasia Information Network) is a high
speed network for research and education which
connect Europe and Asia
• TEIN4 enable 55 million users and 1000 R&E center to
participate project across Europe and Asia
• OF@TEIN is initially as OpenFlow-SDN enabled Testbed
across TEIN infrastructure
• OF@TEIN planned for Open Federation SDN-Cloud
Testbed across TEIN infrastructure (OF@TEIN+)

16. SDN for Inter-Cloud-DC Connectivity Requirements
1. Providing cloud provider and tenant user to control and manage
their applications as well as their connectivity
2. The connectivity requirements including creating virtual topology
and construct network layer information for each tenant
3. Allowing finer-grained control over network paths between
distributed cloud services to provide fast-failover and traffic
prioritization
4. Integrating different model and application programming
interface (API) between cloud (orchestration) controller and SDN-
based virtual network services
