Millimeterwave_onos_app

A millimeterwave application based on onos

Prerequisites

• Java 8 JDK (Oracle Java recommended; OpenJDK is not as thoroughly tested)
• Apache Maven 3.3.9
• git
• bash (for packaging & testing)
• Apache Karaf 3.0.5
• ONOS (git clone https://gerrit.onosproject.org/onos)
  ----->More information you can find here

Installation

git clone https://github.com/DINGDAMU/millimeterwave-onos-app.git
cd millimeterwave-onos-app
mvn clean install
onos-app localhost reinstall! app/target/*.oar

Usage

This application can acquire the mininet's topology from different subsystems via northbound APIs, such as HostService, LinkService and DeviceService.

Show all components by default

onos>showcomponets  

Show only devices

onos>showcomponets -d  

Show only links

onos>showcomponets -l  

Show only hosts

onos>showcomponets -h  

This application can also add addtional annotations on devices, links and ports by commands.

Add additional annotations on devices

onos>annotate-devices <deviceID> <key> <value>  

Add additional annotations on links

onos>annotate-links <source-connectPoint> <destination-connectPoint> <key> <value>

Add additional annotations on ports

onos>annotate-ports <deviceID> <Port number> <Port state> <key> <value>

Get the K shortest paths with own custmized link weight

onos>mmwave-devices-paths <source DeviceId> <destination DeviceId>
onos>mmwave-hosts-path <source hostID> <source hostID>

In our case, the cost depends from the annotation value "probablity of success".
total cost = fixed cost + dynamic cost
In Ethernet case, total cost = 100 + 1; (ps = 100)
In mm-wave case, total cost = 1 + 1/(ps/100);

Conditions before choosing the shortest path

All the switches are considered as indipendent, so the total packet loss = 1 - Ps1 * Ps2 * .... (All the switches in the path).
The total packet loss should be less than the constraint which is given via RESTful API.

onos>mmwave-hosts-path -f <source hostID> <source hostID>  

Filter the K shortest paths with the packet loss constraint.

Add mm-wave intents

onos>mmwave-add-intents <hostId 1> <hostId 2>  

Add the intent between host1 and host2, the path will be the shortest path which calculated by own cost instead of the default cost by add-host-intent command.

Use JSON files to annotate millimeterwave links and port

A JSON example

{
 "apps" : {
"org.onosproject.millimeterwavelink" : {
  "links" : [{
    "src":"of:000000000000000e/5",
    "dst":"of:000000000000000f/3",
    "length": "100",
    "capacity":"100",
    "technology":"mmwave",
    "ps":"86"
  }]
},
"org.onosproject.millimeterwaveport" : {
  "ports" : [{
    "technology":"mmwave",
    "deviceID": "of:000000000000000a",
    "portnumber":"1",
    "isEnabled":"true"
  }]
 },
"org.onosproject.millimeterwaveport" : {
  "hosts" : [{
         "hostid":"mmwave",
         "packetlossconstraint": 0.2,
         "maxpaths": 10
       }]
      }
}

Configuration

 onos>onos-netcfg <ONOS's address> <path to JSON>  

MM-wave Topo overlay on WEB GUI

• Start display mode: Highlight millimeter wave links in green color.
• Cancel display mode: No more highlight millimeter wave links.
• Show all related intents
• Show previous related intent
• Show next related intent
• Monitor traffic of selected intent

In addition, the number of mm-wave and Ethernet links will be shown on the Summary panel.
