Instrumentation Aggregate Manager

This service controls the RF test system that is the core of Sandbox 4. It is used to control attenuation values between pairs of ports (ie. the eight (8) nodes and wimax BS) through the standard OMF URL based services. The service also controls selection of which devices (eg. node or basestation) are connected to the RF test system on a per port basis. Current state of SB4 is available at ​visualization page.

set: Set a single attenuator value

Set the attenuation value on given port pairs:

set

  <service name="set">
     <info>This service sets attenuation for ports pair.</info>
     <args>
       <arg name="portA" isRequired="true" value="port">
         <info>Port number </info>
       <arg name="portB" isRequired="true" value="port">
         <info>Port number </info>
       </arg>
       <arg name="att" isRequired="true" value="att">
         <info>attenuation </info>
       </arg>
      </arg>
    </args>
  </service>

Example: set the attenuation value between node1-1 and node1-2 to 20 dB

$ wget -O status http://internal2dmz.orbit-lab.org:5054/instr/set?portA=1\&portB=2\&att=20

get: Get a single attenuation value

Get the attenuation between a given pair of ports

get

  <service name="get">
    <info>This service gets attenuation for ports pair.</info>
    <args>
       <arg name="portB" isRequired="true" value="port">
         <info>Port number </info>
       </arg>
       <arg name="portA" isRequired="true" value="port">
         <info>Port number </info>
       </arg>
    </args>
  </service>

Example: get the attenuation between node1-1 and node1-8

$ wget -O status http://internal2dmz.orbit-lab.org:5054/instr/get?portA=1\&portB=8

default: Set all attenuators to default values

default

  <service name="default">
     <info>This service load default configuration.</info>
  </service>

The default configuration sets all attenuators to 0 dB attenuation (i.e. full connectivity between all of the nodes including the WiMAX basestation).

status: Get all attenuator values

Get attenuation values on all port pairs

status

  <service name="status">
     <info>This service outputs attenuation for all pairs.</info>
  </service>

$ wget -O status http://internal2dmz.orbit-lab.org:5054/instr/status 

list: List all stored configurations

list

  <service name="list">

      </arg>
    </args>
  </service>

save: Save current attenuator settings

Store current attenuator settings under with the name into internal database .
