    54 SPP Nodes will be located at Internet2 backbone sites. SPP nodes are not being developed to support the termination of VLAN tags, thus requiring a VLAN aware switch to connect to the SPP 1Gbps I/O.

     54SPP Nodes will be located at Internet2 backbone sites.  Five sites are currently planned for GENI (see [http://groups.geni.net/geni/attachment/wiki/presentations/gec-Turner_2008-10.ppt the plan briefed at GEC3].  SPP nodes are not being developed to support the termination of VLAN tags, thus requiring a VLAN aware switch to connect to the SPP 1Gbps I/O.

    6666''IP addresses''
    6767
    68 Each SPP needs one public IP address, which is used by experimenters and others who want to access the SPP.  The virtual Ethernet interfaces do not use IP addresses.  There is a possible need for a non-advertised IP address for each SPP for debugging, console, and other types of maintenance access.  Public addresses have been requested from Internet2.
     68Each SPP needs at least one public IP address, which is used by experimenters and others who want to access the SPP.    As usage expands, up to 3 additional addresses would be needed.  The virtual Ethernet interfaces do not use IP addresses.  There is also a need for at least one non-advertised IP address for each SPP for debugging, console, and other types of maintenance access.  Public addresses have been requested from Internet2.

    7070IP connectivity between the PlanetLab clearinghouse and the SPP nodes is required.
     
    7676Although the SPP does not terminate VLANS, it is VLAN-aware (can identify tags for example), and should eventually be able to manipulate VLANs as part of the PlanetLab control framework.  Initially, we plan that Internet2 will create static virtual Ethernets with distinct tags between each pair of SPPs in the I2 core !PoPs (two SPPs are in Spiral 1).  PoP locations for GENI deployment are under discussion with I2.

    78 To supoort some kinds of end-to-end non-IP experiments, virtual ethernets through regional networks to experiment data sources and sinks will also be needed.  These will be created incrementally in the spirals, as early experimenters join the integration teams.  The endpoints and regional networks are currently TBD, but some likely early candidates will come from other project sites in the PlanetLab control framework in Spiral 1.
