DARPA Spectrum Challenge visualization consist of a set of HTML 5 (i.e. browser) based visualization tools that relies heavily on [http://en.wikipedia.org/wiki/WebSocket websockets] and requires access to monitoring nodes in the ORBIT infrastructure. For the end user, the only way to gain this access is through ssh tunneling. Once user has approved and current time slot, the following SSH command can be used to establish required tunnels:
{{{
ssh -L 6100:10.50.10.10:6100 -L 6101:10.50.10.10:6101 -L 6102:10.50.10.10:6102 -L 6103:10.50.10.10:6103 -L 6104:10.50.10.10:6104 -L 6105:10.50.10.10:6105 -L 6106:10.50.10.10:6106 -L 6107:10.50.10.10:6107 -L 6108:10.50.10.10:6108 -L 6109:10.50.10.10:6109 -L 6110:10.50.10.10:6110 -L 6111:10.50.10.10:6111 -L 6112:10.50.10.10:6112 -L 6113:10.50.10.10:6113 username@console.grid.orbit-lab.org

Once required tunnels are established, competitive matches can be visualized by pointing your '''Chrome''' (other browsers are not guaranteed to work) browser at: 

'''[http://www.orbit-lab.org/status/DSC/dsc-comp.html http://www.orbit-lab.org/status/DSC/dsc-comp.html]'''. 

As can be seen in Figure 1, browser window is separated into two areas: spectrum visualization on the top and packet server status at the bottom. 


Source and destination nodes spectral occupancy is shown in respective panes and color is used to distinguish the teams. In between the two panes, the match time slider is used to indicate the current match time. 

The bottom part of the browser window shows the state of the packet server. Each team has transmit and receive checkerboards of 6 x 25 fields where each field corresponds to 100 packets. Color saturation is used to indicate the fraction of 100 packets that were successfully processed (pulled by the transmitter or pushed by the receiver and successfully verified by the scoring server). The table in the lower right corner shows basic numerical stats for both teams.
