Network Architecture

We enforce a split between "Control", "Data", and "Infrastructure" networks. Control and Infrastructure share a common infrastructure, using VLANs to provide isolation. Together these provide services and user access to the testbed.

The Data networks operate on physically separate hardware, to preserve repeatability of experiments, and to prevent experiments from interfering with testbed services.

Networks do not span sites, with access being done via L3 tunnels, or public internet.

The Instrumentation network is special, in that it is accessible to experiments, but is managed by infrastructure services. This provides, for example, optical or RF devices that need direct L2 access to multiple domains. Access to this network is granted on a case by case basis to experiments. This is also the only L2 network that spans sites.

Currently, the only two sites are the main deployment in NYC, and the sandboxes at Rutgers, in North Brunswick NJ.

Consoles give user access from outside and communicate with services on the DMZ network, and access to the testbed devices over control.

Network Roles

Each Domain has a control network, that is statically configured, as well as two configurable data plane networks. Imaging and other configuration tasks is done via the control network, while experiment and radio traffic is passed on the data networks.

In addition, each "site" has some infrastructure networks.

• CM: used for power control of nodes, not directly accessible to users, instead is managed by services
• Inside: Private network for service traffic, VM Storage traffic, etc.
• DMZ: User accessible network for service traffic
• MGMT: Private network for control of network devices, VM Cluster synchronization, etc.
