Cluster B Integration Meeting on February 13, 2009

​Invitation

A Cluster B integration meeting was organized by the GPO and held in Denver on February 13, 2009, to review and agree on how networking aggregates will be  supported by the Cluster B GENI control plane in Spiral 1.  Key technical  contributors for the PlanetLab and Enterprise GENI projects attended, along with  representatives from other networking projects in Cluster B, and the SPP (server)  project.  The PI from the !ProtoGENI project also attended, since !ProtoGENI must  support networking and interoperate with PlanetLab.  See below for copies of slides and related  documents. 

The Cluster B control framework is based on PlanetLab, which has well established  arrangements for interfacing with nodes (servers) that can include links.  The  PlanetLab GENI project has provided “GENIwrapper ” code that could be used to  independently develop an Aggregate Manager for a networking entity;  currently the  GpENI project intends to use this interface design approach. 

However, the Enterprise GENI project examined the PlanetLab code and expressed  concerns about the time and effort it may take to integrate OpenFlow equipment  and meet their deployment goals given the current state of the code and interfaces.   Instead, they suggested the introduction of a “lightweight” protocol, fully defined by  a WSDL, for use between a modified Cluster B Slice Manager (SM) and a new  “lightweight” Aggregate Manager (AM) that would be part of the OpenFlow  equipment.  Guido Appenzeller presented a detailed proposal of their approach at  the meeting.   

After a lively and candid discussion among all parties, an approach was formulated  and agreed upon to allow the introduction of a “lightweight” protocol into Cluster B,  and support it alongside existing protocols.  This seems to have the lowest risk in  meeting Spiral 1 integration goals.  A “starter kit” of code for the new AM and a  modified SM will be provided by the Enterprise GENI project (Guido Appenzeller).   In particular, Enterprise GENI proposed to write the first revision of the WSDL file  to define the Web Services interface.  Then, the PlanetLab GENI project (Larry  Peterson) will integrate this code into their SM so that both approaches would be  supported during Spiral 1, on a project by project basis.  This should allow the  Enterprise GENI project to meet their ambitious deployment goals, and it will  exercise a “lightweight” protocol within Cluster B and GENI. 

Other topics were discussed durithat GENI should begin to focus RSpec for resource description.
