    7 This meeting was held to investigate how to best integrate network components and aggregates into Cluster B.

     9A 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 
     10supported by the Cluster B GENI control plane in Spiral 1.  Key technical 
     11contributors for the !PlanetLab and Enterprise GENI projects attended, along with 
     12representatives from other networking projects in Cluster B, and the SPP (server) 
     13project.  The PI from the !ProtoGENI project also attended, since !ProtoGENI must 
     14support networking and interoperate with !PlanetLab.  See below for copies of slides and related 
     15documents.

    11 Slides and Documents:
     17The Cluster B control framework is based on !PlanetLab, which has well established 
     18arrangements for interfacing with nodes (servers) that can include links.  The 
     19!PlanetLab GENI project has provided “GENIwrapper ” code that could be used to 
     20independently develop an Aggregate Manager for a networking entity;  currently the 
     21GpENI project intends to use this interface design approach.

    13   Goals for This Meeting.  -  Aaron Falk, GPO
     23However, the Enterprise GENI project examined the !PlanetLab code and expressed 
     24concerns about the time and effort it may take to integrate !OpenFlow equipment 
     25and meet their deployment goals given the current state of the code and interfaces.  
     26Instead, they suggested the introduction of a “lightweight” protocol, fully defined by 
     27a WSDL, for use between a modified Cluster B Slice Manager (SM) and a new 
     28“lightweight” Aggregate Manager (AM) that would be part of the !OpenFlow 
     29equipment.  Guido Appenzeller presented a detailed proposal of their approach at 
     30the meeting.   
     31
     32After a lively and candid discussion among all parties, an approach was formulated 
     33and agreed upon to allow the introduction of a “lightweight” protocol into Cluster B, 
     34and support it alongside existing protocols.  This seems to have the lowest risk in 
     35meeting Spiral 1 integration goals.  A “starter kit” of code for the new AM and a 
     36modified SM will be provided by the Enterprise GENI project (Guido Appenzeller).  
     37In particular, Enterprise GENI proposed to write the first revision of the WSDL file 
     38to define the Web Services interface.  Then, the !PlanetLab GENI project (Larry 
     39Peterson) will integrate this code into their SM so that both approaches would be 
     40supported during Spiral 1, on a project by project basis.  This should allow the 
     41Enterprise GENI project to meet their ambitious deployment goals, and it will 
     42exercise a “lightweight” protocol within Cluster B and GENI. 
     43
     44Other topics were discussed durithat GENI should begin to focus RSpec for resource description.
