  1. Supporting the development of distributed systemsCS606, Xiaoyan HongUniversity of Alabama

  2. outline Using virtualization and federation • Example of PlanetLab • Example of EmuLab • Example of ProtoGENI

  3. EmulabSystem Setup

  4. An Example of Emulab Site

  5. Emulab’s Administrative Structure • Emulab has a two level administrative structure: “Projects”, and “Groups” • Plus “ElabAdmins” on top, and “Users” on the bottom • E.g., a class project with multiple, isolated groups (created by the project leader) • Administrative control is delegated to “leaders” at each level • Project gets its own disk space/tree • Users may join multiple projects • Groups are independent • Files/experiments are protected from each other • Groups can share • Share the common project file hierarchy

  6. Account • Obtain an account : • clicking "Request Account" and then  "Join an Existing Project" on the new page. • You will need to join the project UA-cs606. https://www.emulab.net/reqaccount.php3

  7. outline • Virtualization and federation • Example of PlanetLab • Example of EmuLab • Example of ProtoGENI

  8. GENI Introduction • The Global Environment for Network Innovations (GENI) • a virtual lab for at-scale networking experimentations • It provides computing and networking resources that are geographically distributed and federated through control frameworks running by different owners • Extremely challenging to achieve security due to many unique GENI features: • Distributed ownerships/user groups • Deep programmability • Super Flexibility of configurability • Large-scale connectivity to Internet • Vast of variety of network patterns

  9. User examples - slices

  10. GENI Development • Hardware • build on mature testbed technologies • Clusters: Planetlab, ProtoGENI (Emulab), ORCA, Orbit, DETER • Develop new hardware for the clusters and connectivity • Software: • Developing control framework as GENI prototyping • Each cluster own control framework. • Federation • Tools to help experiments • Operation and management • Security

  11. ProtoGENI Introduction • What is ProtoGENI? • A prototype GENI • Ahardware facility providing computing and networking resources based on Emulab • A software application defining a control framework • www.protogeni.net
