     3SB9 is dedicated to [http://www.openflow.org OpenFlow] experimentation (NOTE: Nodes in SB9 don't have wireless interfaces!).
     4As show in Figure 1, Sanbox 9 is built around an !OpenFlow capable switch with 9 nodes 7 of which are equipped with [http://www.netfpga.org NetFPGA] cards and 2 general purpose ORBIT nodes and a sandbox console.

     9The switch labeled 'sw-sb-09', a [http://www.prontosys.net/pronto3290.htm Pronto 3290],  provides the central connectivity backplane for 'DATA' interface of all hosts/NetFPGAs in the sandbox. Each host (node1-1..node1-7, node1-10..node1-11) is connected to the sw-sb-09 switch through one 1GbE data connection on the interface 'eth0' or 'exp0'. As is the case with the rest of ORBIT nodes, a second GbE interface ('eth1' or 'control') of each node,  that is used exclusively for experiment control (incl. ssh/telnet sessions), is connected to an external control switch outside of sandbox.

     11The first 7 hosts (node1-1..node1-7) each contain a 4x1GbE NetFPGA installed on a PCI slot. Each NetFPGA has 4 connections to the top switch, corresponding to its 4-GbE ports nf2c0-nf2c3.

     13The Pronto switch is a !OpenFlow enabled switch and can be run in native or !OpenFlow mode by controlling its boot configuration. When in native mode, it runs the Pica8 Xorplus switch software while when it is in !OpenFlow mode it can run either stock Indigo firmware or experimenter provided !OpenFlow image for Pronto switches. The mode of operation is controlled by the [wiki:Software/AM/Network network aggregate manager] service.
