Internet2 GENI Core Networks

GENI Sites can be connected directly, or indirectly via a Regional network, to the Internt2 core networks Advanced Layer2 Service (AL2S) and/or Interoperable On-demand Network (ION). The AL2S network provides scalable and flexible access to short or long-term Layer 2 circuits between GENI endpoints on the I2 Network and beyond. GENI core networks AL2S and ION are run by ​Internet2 a community of research, academia, industry and government technology contributors. For detailed information about the AL2S and ION networks see the ​Internet2 Advanced Networking page. Please note that the ION service is being phased out. For details on connection for GENI Sites see the GENI Connectivity page.

Some tools are available for operators to debug I2 Core Network connectivity issues:

• ​I2 AL2S Router Proxy tool
• ​I2 ION Router Proxy tool

To submit questions, issues, connection requests send email to ​noc@net.internet2.edu. Problem reports can also be directly submitted via the ​problem report page.

GENI AL2S

​AL2S is part of the Internet2 ​Advanced Networks Service offerings. GENI AL2S allows experimenters to create their own backbone point-to-point VLANs using infrastructure already in place. For a list of research and educational organizations connecting directly to the Internet2 Network see the list of ​Network Connectors.

GENI Network Stitching experiments in AL2S

Most GENI sites connected to AL2S support GENI Network Stitching. See the AL2S GENI aggregate page for a list of sites that support stitching via AL2S. The AL2S GENI aggregate supports the GENI AM API which enables experimenters to request GENI Network Stitching connections via the ​Omni tools or the ​GENI portal. Experimenters do not interact with AL2S directly, the GENI tools determine the required connection and make the request to the AL2S aggregate.

ExoGENI Stitching experiments in AL2S

ExoGENI sites are also connected to AL2S and support stitching via the ExoGENI Service Manager (ExoSM). These connections are supported by the ExoGENI team and issues or questions relating to these types of connections should be submitted to the mail list ​geni-orca-users@googlegroups.com.

GENI OpenFlow Experiments in AL2S

OpenFlow experiments will soon be possible with the GENI Learning Switch controller or with an experimenter developed controller. Controllers are validated by Internet2 before being allowed to control I2 Core switches.

The GENI AL2S Controller is a simple applications that:

• floods all traffic until the path is learned
• learns MAC addresses
• reacts to network traffic by installing new flow rules (“learning”) allowing end‐to‐end communication

GENI ION

Internet2 ION is a network service that allows experimenters to create dedicated point-to-point optical circuits via the GENI AM API interface. Some GENI sites connected to ION support GENI Network Stitching. See the ION GENI aggregate page for a list of sites that support stitching via ION.

OpenFlow Experiment in ION

The GENI OFI2 Internet2 project page give insight into the original plans for an OF deployment. The Internet2 ION OpenFlow Aggregate (i2-of) include these DPIDs in the OpenFlow core:
