     7==== Description ====
     9  This meeting will strive for consensus on a software architecture
     10  for network stitching in GENI.  A key architectural question for
     11  GENI has been how to connect the resources provided by multiple
     12  aggregates into a coherent network.  The key objective is to enable
     13  automated and realtime network stitching for slices which span
     14  multiple aggregates.  Ethernet VLANs have been identified as the
     15  initial network technology to provide slice level inter-aggregate
     16  connections and isolation.  However, there are many architecture and
     17  design decisions still required.  These include, how do you select
     18  the VLAN IDs to use and inform all necessary aggregates?  How do you
     19  handle external networks which may be in between two GENI Aggregates
     20  of interest?  Is the network stitching service a shared service
     21  which coordinates across aggregates, or are aggregates responsible
     22  for coordinating amongst themselves, or a hybrid model?  How is
     23  stitching related information described and shared ?
     25  Over the years the community has discussed this in various forums,
     26  and multiple implementations are in use in the community.  However,
     27  it is now critical to define an architecture and design which will
     28  enable networking stitching to be generally available within GENI.
     29  In recent weeks that discussion has become more focused and several
     30  key stakeholders have debated various alternatives.  This meeting
     31  will include a presentation of a proposed GENI network stitching
     32  architecture and alternatives, and an open community discussion on
     33  these issues.
