A key architectural question for GENI has been how to connect the resources provided by multiple aggregates into a coherent network. The key objective is to enable automated and realtime network stitching for slices which span multiple aggregates. Connecting resources across aggregates remains a significant challenge and requirement for GENI.

During this meeting, we will demonstrate a common RSpec element to describe stitching resources, and progress on dynamic VLAN instantiation between ProtoGENI and MAX via ION. We will then try to agree on the schema for that RSpec element, and then discuss APIs for coordinating network stitching across GENI aggregates.
