141 | | Layer 2 Connectivity: There is currently no usable layer2 connection to the UMass Amherst lab available for GENI (this is the same lab that the [wiki:DOME] project uses). The project is investigating the possibility of installing local fiber that could enable a connection to NLR through an appropriate regional network. If installed, this fiber would support both the [wiki:DOME] and [wiki:ViSE] projects. Field locations might be accessed via IP tunnels or layer2 VLANs--investigation is ongoing. |
| 141 | Layer 2 Connectivity: In cooperation with OIT at UMass-Amherst we have provided a VLAN connection from our control plane server geni.cs.umass.edu to an Internet2 point-of-presence in Boston. An [http://groups.geni.net/geni/attachment/wiki/DOME/mou.pdf MOU] was agreed upon with the UMass Office of Information Technology (OIT) regarding connecting Internet2 to the DOME and ViSE servers, along with |
| 142 | VLAN access. The OIT contact is Rick Tuthill, tuthill email at oit.umass.edu. The agreements include:[[BR]] |
| 143 | 1) CS shall order OIT-provisioned network jacks in appropriate locations in the Computer Science building using normal OIT processes. (completed) [[BR]] |
| 144 | 2) OIT shall configure these jacks into a single VLAN that shall be extended over existing OIT-managed network infrastructure between the Computer Science building and the Northern Crossroads (NoX) Internet2 Gigapop located at 300 Bent St in Cambridge, MA.[[BR]] |
| 145 | 3) OIT agrees to provide a single VLAN for “proof-of-concept” testing and initial GENI research activities. [[BR]] |
| 146 | 4) The interconnection of the provided VLAN between the NoX termination point and other Internet2 locations remains strictly the province of the CS researchers and the GENI organization.[[BR]] |
| 147 | 5) This service shall be provided by OIT at no charge to CS for the term of one year in the interest of OIT learning more about effectively supporting network-related research efforts on campus. [[BR]] |
143 | | IT contact at UMass Amherst ? [[BR]] |
| 149 | In an email dated September 28th, 2009 Rick Tuthill of UMass-Amherst OIT updated us on the status of this connection, as follows:[[BR]] |
| 150 | 6) The two existing ports at the CS building in room 218A and room 226 and all intermediary equipment are now configured to provide layer-2 VLAN transport from these networks jacks to the UMass/Northern Crossroads(NoX) handoff at 300 Bent |
| 151 | St in Cambridge, MA. [[BR]] |
| 152 | 7) The NoX folks are not doing anything with this research VLAN at this time. They need further guidance from GENI on exactly what they’re supposed to do with the VLAN. [[BR]] |
| 153 | 8) Also, once IP addressing is clarified for this VLAN, we’ll need to configure some OIT network equipment to allow the selected address range(s) to pass through. [[BR]] |
| 154 | |
| 155 | We intend this VLAN connection to service both the ViSE and the DOME testbeds. Note that Layer 2 ethernets will not extend to the DieselNet nodes, due to limitations in the existing deployed systems, but IP tunnels to the layer 2 VLAN termination points should be feasible for connecting mobile endpoints to the GENI virtual ethernets.[[BR]] |
| 156 | |
| 157 | In the coming year, we have committed to planning with our peers in Cluster D and the GPO on how to best use this new capability. As part of this plan, and before we can send/receive traffic on this link, we will discuss the roles and capabilities of Internet2 in forwarding our traffic to its correct destination. [[BR]] |
