= GENI layer1transport service =

== Introduction ==
These pages explain how to install and use the layer1transport service.  This service is used to implement layer-1-style forwarding through OpenFlow-enabled switches using user-defined match criteria.  Think along the lines of an operator-facing service that sets up and maintains pseudowires based on some combination of ingress-port/egress-port, DPID, VLAN ID, subnet, etc.  The flows for forwarding this traffic are statically defined in files for the service to manage.

The GPO wants to provide GENI experimenters with a view of a pure !OpenFlow network on the mesoscale VLANs, and the layer1transport package is one tool that administrators can use to provide such a view of the network to experimenters. MAC address learning on point-to-point VLANs that pass through non-OF switches can interfere with certain forwarding patterns that are possible in pure !OpenFlow network. One specific place we see this problem is on non-OF VLANs that are used for VLAN translation on the !OpenFlow Backbone switches. 

== Current version ==
The current available version of the layer1transport service is: 1.0.0.

This version of the layer1transport service uses [http://www.projectfloodlight.org/ Floodlight] and the [http://docs.projectfloodlight.org/display/floodlightcontroller/Static+Flow+Pusher+API Static Flow Pusher] service that is distributed with Floodlight.
