Layer 2 Services
Internet2's Advanced Layer 2 Service delivers a strategic advantage for leaders in research and education (R&E) by providing effective and efficient wide area 100 gigabit Ethernet technology. CIOs and IT staff can now provide a turnkey solution for balancing long-term or short-term global big data science collaborations and production services.
Enabling scalable and flexible global access to an open exchange network, members can build Layer 2 circuits (VLANs) between endpoints on the Internet2 Network and beyond. The service meets the wide-ranging needs of the research and education community—both now and into the future.
AL2S allows users to create their own VLANs on the Internet2 AL2S backbone. Static or Dynamic, point-to-point or multipoint, intra-domain or inter-domain, AL2S puts control of the backbone VLANs into the users' hands for the creation of purpose-built private circuits using infrastructure already in place.
Some features of Internet2's Advanced Layer 2 Service are:
- STATIC VLANs: point-to-point or multipoint, configured on demand by the user through a portal.
- DYNAMIC VLANs: point-to-point or multipoint. The option to configure VLANs dynamically using software-defined networking (SDN) through technologies such as OpenFlow. Please see here for more details.
- INTERDOMAIN CONNECTIVITY: global R&E and Global Optical Lightpath Exchange fabrics enable Ethernet VLANs throughout the U.S. on Internet2 and around the world through partner networks to intercommunicate.
Links to an Advanced Layer 2 Network map and Infosheet can be found in the box to the right.Internet2 produces reports detailing the availability and bandwidth of the AL2S network. These reports along with spreadsheets listing the values for metrics related to Change Management and Incident Management can be found here.
A link to documentation, presentations, and copies of slides and recordings of webinars can be found here.
A list of organizations connected to AL2S at both 100GE and 10GE is available here.

How can my organization connect to AL2S?
What is the physical infrastructure of AL2S?
If my organization is behind a regional connector, who has rights to assign VLANs?
What is the advantage of AL2S?
What is OESS?
OESS is a set of software used to configure and control dynamic (user-controlled) layer 2 virtual circuit (VLAN) networks on OpenFlow enabled switches. OESS provides sub-second circuit provisioning, automatic circuit failover, per-interface permissions, and automatic per-VLAN statistics. It includes simple and user friendly web-based user interface as well as a web services API.
Please see http://globalnoc.iu.edu/sdn/oess.html for more information.
A demo of the OESS user interface is available here. Use GRNOC as the suggested selection then sign in using Login: os3e with Password: os3edemo.
Can I connect to all other AL2S ports?
How do I get permission to build a circuit to another port that I do not own?
Are multipoint vlans available?
What is SDN?
"Software-Defined Networking (SDN) is an emerging architecture that is dynamic, manageable, cost-effective, and adaptable, making it ideal for the high-bandwidth, dynamic nature of today's applications. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services."
What is the difference between SDN and OpenFlow?
"Software Defined Networking (SDN) is an emerging network architecture where network control is decoupled from forwarding and is directly programmable."
"OpenFlow is the first standard communications interface defined between the control and forwarding layers of an SDN architecture."
I have a different controller I want to try, can I do that?
Is the use of OESS software required?
How does GENI fit in?
GENI resources on campuses and in regionals can be accessed directly using AL2S, thus it can tie together multiple resources (e.g., compute instances on GENI Racks). AL2S also has four 10G connections into the GENI mesoscale backbone being operated by Internet2, to access existing resources.
I have a GENI researcher; can he or she use AL2S to get access to GENI resources?
What is the FlowSpace Firewall?
