OpenFlow in AL2S Today: Considerations…

• Review AL2S constraints/requirements• Single VLAN slice: no translation required• Multiple VLAN slice: translation• AL2S default action: drop all flows

• Get topo from I2 folks• Proactively install flows to point traffic to controller

• Ensure controller handles wildcards properly• Remove “delete all flows on ctrl startup” component• On AL2S you have no access to your controller • L2/L3 mode…• Topology discovery? request VLAN

• Review AL2S questionnaire

• Review AL2S “operational readiness” docs• Package RPM for CentOS/RedHat• Init script• Syslog• Daemonize• Versioning• Operational documentation• Ticketing

GeniSiteMon Process Review…

• Download pox from public repo• Develop controller on CentOS

• Inert logging info• Init• Daemonize• Package

• Trac: ticketing, Git repo, bug reports • Contact I2 folks and complete “Questionnaire”• Email package to I2 folks

GeniSiteMon Process Review

• Test controller on iDREAM• Get approvals from I2 to deploy on AL2S• I2 folks will reserve AL2S resources for you• Reserve GENI resources • Deploy experiment

Next Steps…• Increase GENI AL2S OF experiments• Automate resource allocation

• Service abstraction• Given RSpec with siteA, siteB, # paths• Stitcher+SCS+OF_OESS

• Edgelist/Adjacency Matrix• Expand research audience:

• optimization, • graph theory, • complex networks
