Sponsored by the National Science Foundation 7 ICDCS13: July 8, 2013 The GENI Portal is… A web-based tool for experimenters to manage experimenters, projects, and slices. Includes simple tools to reserve resources. More to come in the future.

Sponsored by the National Science Foundation 8 ICDCS13: July 8, 2013 Flack is … A graphical user interface (GUI) for: –designing topologies in GENI –reserving resources in GENI

Sponsored by the National Science Foundation 9 ICDCS13: July 8, 2013 Experimenter An experimenter is a researcher who uses GENI resources Different types of experimenters have different roles and permissions: Advisor vs Grad Student Teacher vs TA vs Student Experimenter

Sponsored by the National Science Foundation 10 ICDCS13: July 8, 2013 Projects Projects organize research in GENI Project Lead Members Slice Projects contain both people and their experiments A project is led by a single responsible individual: the project lead

Sponsored by the National Science Foundation 11 ICDCS13: July 8, 2013 Creating Projects Only project leads can create projects. Project names are public, unique and permanent A project may contain many experimenters; an experimenter may be a member of many projects Projects have an optional expiration (e.g. for classes, tutorials) For today’s tutorial we will all join a project which expires in about a week

There are several ways to offer your private key to ssh. You should never be prompted for a password to log into a GENI compute node. If you are, something has always gone wrong. No password!

Today we will use tool called an ssh agent. $ ssh-add ~/.ssh/id_geni_ssh_rsa $ ssh -p You should never be prompted for a password to log into a GENI compute node.

Resource specifications are used to describe and request resources. Examples: Compute: computer vs virtual machine (VM) Wireline Network: VLAN or OpenFlow Wireless: WiMAX

Sponsored by the National Science Foundation 23 ICDCS13: July 8, 2013 Aggregate An aggregate manages a set of reservable resources Aggregates include: GENI racks OpenFlow WiMAX InstaGENI RackExoGENI Rack

Sponsored by the National Science Foundation 24 ICDCS13: July 8, 2013 Slice A slice is a container of resources used in an experiment. A slice can contain resources from one or more aggregates A slice is in a single project A slice has an expiration Slice names are public, reusable and unique
