| 5 | Period: GEC9 - GEC10 |
| 6 | |
| 7 | '''Note:''' This is a "comprehensive" report for the three GENI subcontracts |
| 8 | held by the University of Utah. For concrete accomplishments, milestones, etc. |
| 9 | I have marked major items in this report with '''''P''''' (for ProtoGENI), '''''A''''', |
| 10 | (for PGAugmentation), or '''''T''''' (for PGTools) to make it clear which activities |
| 11 | were conducted under which subcontract. |
| 12 | |
| 13 | == I. Major accomplishments == |
| 14 | |
| 15 | === A. Milestones achieved === |
| 16 | |
| 17 | '''''T'' PGTools: S3.a:''' User guide for map interface |
| 18 | |
| 19 | Created a new guide for the Map interface to ProtoGENI (and other GENI) resources, which |
| 20 | can be found at: [http://www.protogeni.net/trac/protogeni/wiki/MapClientManual]. The map |
| 21 | interface itself has been greatly improved (more on this below), and is now on the |
| 22 | front page of [http://www.protogeni.net/] |
| 23 | |
| 24 | '''''T'' PGTools: S3.b:''' Prepare tools for export to other Emulab sites |
| 25 | |
| 26 | The Emulab frontend to ProtoGENI has been cleaned up an generalized, so that other Emulab |
| 27 | sites participating in ProtoGENI can enable it for their users. The University of Kentucky |
| 28 | has been the first external site to test this feature. |
| 29 | |
| 30 | Though not originally part of this milestone, we have also made changes to the map client |
| 31 | to make it easier to host it on sites other than protogeni.net . |
| 32 | |
| 33 | '''''T'' PGTools: S3.c:''' Read-Only mode for map interface |
| 34 | |
| 35 | There is now a "read only mode" for the map interface, which gives anyone an interactive |
| 36 | veiw of GENI resources, without the need for an account at any GENI aggregate. This uses |
| 37 | a set of advertisement RSpecs that are hosted on the ProtoGENI webserver, and which are |
| 38 | updated nightly from all participating aggregates. |
| 39 | |
| 40 | The map interface is able to run complete in "read only" mode, start read-only but include |
| 41 | a "log in" button, or to present the user with a selection screen when it starts at to whether |
| 42 | they want to run in authenticated or read-only mode. |
| 43 | |
| 44 | We have made many more improvements to our map interface than anticipated when we set the |
| 45 | milestones; see below for more details. |
| 46 | |
| 47 | '''''P'' ProtoGENI.S2.h:''' Deploy 3 additional backbone network nodes |
| 48 | |
| 49 | Working with HP and Internet, we deployed 3 more backbone sites in Los Angeles, Houston, |
| 50 | and Atlanta. These are connected to each other and the previously existing sites at |
| 51 | Layer 2, and are available for experimenters to use. |
| 52 | |
| 53 | '''''P'' ProtoGENI.S3.a:''' Improved experimenter support |
| 54 | |
| 55 | We have significantly re-worked the status codes returned by the ProtoGENI API in order |
| 56 | to improve the user experience: users now have much more information about why calls they |
| 57 | make may have failed (previously, they usually had to ask the ProtoGENI administrators for |
| 58 | this information). |
| 59 | |
| 60 | '''''P'' ProtoGENI: S3.b:''' Demonstration and Outreach at GEC10 |
| 61 | |
| 62 | We presented our map interface in the GEC demo session and status reports sessions, showing |
| 63 | both ProtoGENI and PlanetLab resources. |
| 64 | |
| 65 | We also made presentation materials that we had used for tutorials at other GECs to groups |
| 66 | doing tutorials at GEC10. We did not produce new materials, as these groups founding the |
| 67 | existing materials to be sufficient. |
| 68 | |
| 69 | '''''A'' PGINTEGRN: S3.a:''' API for AM<->AM coordination during stitching |
| 70 | |
| 71 | We described an API for stitching between aggregates; a description of our design can be |
| 72 | found here: |
| 73 | |
| 74 | [http://www.protogeni.net/trac/protogeni/wiki/Stitching] |
| 75 | |
| 76 | We also participated in extensive discussions regarding an eventual GENI-wide stitching API. |
| 77 | |
| 78 | '''''A'' PGINTEGRN: S3.b:''' Implement AM <-> AM coordination API |
| 79 | |
| 80 | We implemented the API described above, and demonstrated it at GEC10, to create Layer 2 |
| 81 | connections from the University of Utah Emulab site to the University of Kentucky and the |
| 82 | University of Wisconsin. |
| 83 | |
| 84 | === B. Deliverables made === |
| 85 | |
| 86 | * Software releases: ''P, T, A'' We have continued to make all software that we develop |
| 87 | available to the public via our git repository at git-public.flux.utah.edu . |
| 88 | * Documentation: ''P, A, T'' in addition to the documentation listed above, we |
| 89 | have documented many of our APIs, data structures, and design decisions |
| 90 | at [http://www.protogeni.net] |
| 91 | * Example code and RSpecs: ''A, T'' In addition to the main source snapshots |
| 92 | and documentation listed above, we have released sample code, RSpecs, NS |
| 93 | files, and more on [http://www.protogeni.net] |
| 94 | |
| 95 | == II. Description of work performed during last quarter == |
| 96 | |
| 97 | === A. Activities and findings === |
| 98 | |
| 99 | We made significant improvements this quarter to our flash map-based interface |
| 100 | (which we will be renaming to "Flack", since 'flash map-based interface' is not |
| 101 | a very catchy name. Many of these improvements are above and beyond the ones |
| 102 | that were listed in our milestones. In particular, we re-worked its communication |
| 103 | with aggregate managers, and added PlanetLab support. |
| 104 | |
| 105 | Previously, the interface used the browser's native https support to contact aggregate |
| 106 | managers, slice authorities, etc. This had a number of drawback, chief among them the |
| 107 | fact that excessive user work was required to add CA certificates and user certificates |
| 108 | to their browser. We have replaced the browser's connection mechanisms with Forge, and |
| 109 | open-source SSL library implemented in Javascript and Flash. This enables us to load |
| 110 | (without user intervention) the same CA bundle used by the ProtoGENI sites, and allows |
| 111 | us to automatically fetch user certificates for users who have an Emulab account. The |
| 112 | result is a much smoother user experience. |
| 113 | |
| 114 | The map interface had also previously used the ProtoGENI API to contact aggregates; we |
| 115 | added support for the new GENI AM API, so that it can contact non-ProtoGENI aggregates. |
| 116 | We verified that this work with PlanetLab aggregates. Since there is not yet a standard |
| 117 | GENI RSpec (though it appears that one is coming), we had to add support for the PlanetLab |
| 118 | RSpec to the interface. This, along with the AM API, allows us to display PlanetLab |
| 119 | resources, and create slivers on them. As more aggregates implement the standard APIs and |
| 120 | a common RSpec is implemented, this will put more and more of GENI "on the map." |
| 121 | |
| 122 | We spend a large amount of time during this period contributing to very useful discussions |
| 123 | with GPO personnel, representatives from other CFs, and other GENI community members, |
| 124 | regarding GENI issues of GENI-wide importance. These culminated in four sessions at GEC10, |
| 125 | regarding identity, authorization, stitching, and RSpecs. The proposals for these four |
| 126 | areas, all of which we provided feedback on, were accepted. |
| 127 | |
| 128 | We also did a significant amount of work on ProtoGENI under funding directly |
| 129 | from the NSF. That work will be detailed in our NSF annual report rather than |
| 130 | this report. |
| 131 | |
| 132 | === B. Project participants === |
| 133 | |
| 134 | The following personnel from Utah worked on these projects: |
| 135 | * Robert Ricci (Research Assistant Professor) |
| 136 | * Leigh Stoller (Research Staff) |
| 137 | * Jon Duerig (Research Staff) |
| 138 | * Gary Wong (Research Staff) |
| 139 | * Dan Reading (System Administrator) |
| 140 | * Matt Strum (Undergraduate Student) |
| 141 | |
| 142 | Others participated in ProtoGENI under direct funding from NSF. |
| 143 | |
| 144 | === C. Publications (individual and organizational) === |
| 145 | |
| 146 | No publications were funded by these projects during this time period. |
| 147 | |
| 148 | === D. Outreach activities === |
| 149 | |
| 150 | * We have been in contact with groups in Korea (KISTI), Taiwan (TWISC), |
| 151 | and China (Tsinghua U.) which are not currently part of GENI, but which are |
| 152 | interested in joining the ProtoGENI federation |
| 153 | |
| 154 | === E. Collaborations === |
| 155 | |
| 156 | We have worked extensively with other projects, both within our cluster and |
| 157 | with other clusters as well. A significant amount of our work, particularly |
| 158 | for the PGAugmentation contract, has involved coordinating with cluster |
| 159 | members, projects outside of the cluster, and users. |
| 160 | |
| 161 | Interaction within the cluster has taken place in the following ways: |
| 162 | * Bi-weekly cluster conference calls, which we lead with the help of our |
| 163 | GPO system engineer, Vic Thomas |
| 164 | * The geni-users@emulab.net and geni-dev@emulab.net mailing lists, which |
| 165 | are used for cluster-wide coordination and development discussions |
| 166 | * Cluster meetings at GECs |
| 167 | * Occasional email exchanges and phone calls with cluster members |
| 168 | |
| 169 | === F. Other Contributions === |
| 170 | |
| 171 | * Robert Ricci is currently served as co-chair of the Control Framework |
| 172 | Working Group, up until GEC10 when the WGs were dissolved |
