| | 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 ? |
| | 24 | |
| | 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. |
