  1. SFI Tutorial Tony Mack

  2. What is SFI SFI: the the command line client for SFA interfaces. SFA: minimal set of interfaces and data types that permit the federation of slice-based network components. • Registry Interface • Slice Interface • Component • Aggregate • Slice Manager

  3. SFA Interfaces Registry Interface - Manage Records • Add • Update • Remove • Show • List Slice Interface - Manage Slices • Resources • Create • Delete • Start • Stop

  4. Current Aggregates PlanetLab (PLC) PlanetLab Europe (PLE) PlanetLab Japan (PLJ) VINI GpENI

  5. Installing SFI [myplc] name= MyPLC  baseurl=http://build.planet-lab.org/planetlab/f8/pl-f8-i386-4.3-k22-latest/RPMS/ enabled=1 gpgcheck=0 Fedora RPM Installation • Add yum repository • Install sfa-client $ yum install sfa-client Install from source $ svn export http://svn.planet-lab.org/svn/sfa/trunk sfa  $ cd sfa/trunk/sfa && python setup.py install

  6. Configuring SFI $ mkdir ~/.sfi • Create sfi directory • Install private key  # username is email without domain  $ cp ~/.ssh/id_rsa ~/.sfi/<username>.pkey  # remove passphrase from key  $ ssh-keygen -p -f ~/.sfi/<username>.pkey • create config file ~/.sfi/sfi_config SFI_AUTH='plc.princeton'  SFI_USER='plc.princeton.tmack'  SFI_REGISTRY='http://www.planet-lab.org:12345/'  SFI_SM='http://www.planet-lab.org:12347/'

  7. Registry Interface

  8.  Add Record <record    description="Test description"    hrn="plc.princeton.tmacktestslice"    type="slice" url="http://planet-lab.org/"              <researcher>plc.princeton.tmack</researcher>          <researcher>plc.princeton.llp</researcher>  </record> • Slice record template • Add the record to the Registry $ sfi.py add slice-record.xml

  9. Update Record $ sfi.py update slice-record.xml

  10. Display Record $ sfi.py show plc.princeton.tmacktestslice • Show detailed record information peer_authority: None      hrn: plc.princeton.tmacktestslice      last_updated: 20100625T18:42:41      authority: plc.princeton      gid:           hrn: plc.princeton.tmacktestslice           urn: urn:publicid:IDN+plc:princeton+None+tmacktestslice          uuid: 98680966165612911378858199233917520628      date_created: 20100625T18:42:41      type: slice      researcher: ['plc.princeton.tmack']

  11. Listing Records $ sfi.py list plc • List all records at a specific level in the hierarchy  plc.iss (authority)  plc.cesnet (authority)  plc.princeton (authority) $ sfi.py list plc.princeton plc.princeton.planetlab-01 (node)  plc.princeton.tmack (slice)  plc.princeton.tmacktestslice (slice)

  12. Slice Interface

  13. Get Available Resources $ sfi.py resources -o nodes.rspec <?xml version='1.0' encoding='ASCII'?> <RSpec type="SFA">     <network name="plc">         <site id="s13">             <name>Princeton</name>             <node id="n10025">                 <hostname>alice.cs.princeton.edu</hostname>                 <bw_limit units="kbps">10000</bw_limit>             </node>             <node id="n10328">                 <hostname>planetlab-9.cs.princeton.edu</hostname>                 <bw_limit units="kbps">10000</bw_limit>             </node>            ...

  14. Get Allocated Resources $ sfi.py resources plc.princeton.testslice -o slice-nodes <?xml version='1.0' encoding='ASCII'?> <RSpec type="SFA">     <network name="plc">         <site id="s13">             <name>Princeton</name>             <node id="n10025">                 <hostname>alice.cs.princeton.edu</hostname>                 <bw_limit units="kbps">10000</bw_limit>                 </sliver>             </node>             <node id="n10328">                 <hostname>planetlab-9.cs.princeton.edu</hostname>                 <bw_limit units="kbps">10000</bw_limit>             </node>            ...

  15. Allocate Resources Pt. 1 • Modify RSpec by hand (adding the <sliver/> tag) • Use client tools Using Client Tools • Get available resources $ sfi.py resources -o nodes.rspec • Create a text file of hostnames $ sfiListNodes.py -i nodes.rspec -o nodes.txt • Remove/Add nodes to/from text file • Create an RSpec with requested resource allocations $ sfiAddSliver.py -i nodes.rspec -n nodes.txt -o mynodes.rspec

  16. Allocate Resources Pt.2  $ sfi.py create plc.princeton.slice mynodes.rspec • Create the slice on the specified resources • Check it $ sfi.py resources plc.princeton.slice • You can use 'sfi.py create' to deallocate resources as well. Just create an RSpec with only the resources you want and execute create again.

  17. Deallocate All Resources $ sfi.py delete plc.princeton.slice

  18. Other Calls • Stop a slice $ sfi.py stop plc.princeton.tmacktestslice • Start a slice $ sfi.py start plc.princeton.tmacktestslice
