# QoS-Slicing
The QoSlicing application provides network slicing with performance isolation to netwrk slices created with the VPLS ONOS application.
The folders/file contain:
* `ONOS File`: contains the files that you have to change in the onos master repository for utilizing the QoS-Slicing application.
* `target`: contains compiled QoS-Slicing application, i.e. the oar file. The compiled file is needed to install the application on ONOS.
* `src`: contains the application java source code.
* `topology`: is a python script for creating a mininet network.
## Changes in ONOS master repository
The folder `ONOS File` contains the files that you have to sobstitute in the ONOS master folder. The files in the `ONOS File` folder
have the same name of the files in the onos master folder. So you have to simply copy/paste it in the right folder.
## Steps to install QoS-Slice in Onos
Before to install QoS-Slice you have to activate the VPLS application, that is included in the ONOS master distribution. To install and activate the QoS-Slicing app you have to run this command in the the Qos-Slicing folder:
onos-app localhost install! org.qosslice.app target/qosslice-app-2.3.0-rc3.oar
Once you have activated the QoS-Slicing you can configure the slices, via CLI or REST interface.
## Example steps to configure QoS-Slice app using the ONOS Command Line Interface
To define a `slice` without performance isolation form host h1 to host h2, you have to run these commands in the onos CLI:
interface-add of:0000000000000001/1 h1
interface-add of:0000000000000004/1 h2
vpls create VPLS-1
vpls add-if VPLS-1 h1
vpls add-if VPLS-1 h2
To add/enrich a `slice` with performance isolation using the "elastic bandwidth isolation" solution, you have to run these commands in the onos CLI:
band -br -uk -b 1000 -dp 1 -nb band1 add-band
qos-slice create SLICE-1 VPLS-1
qos-slice add-band SLICE-1 band1
qos-slice add-meter SLICE-1
With these commands a number REMARK meters are installed in the switches belonging to the slice `SLICE-1` to remark the packets exceeding 1 Mbps. Moreover, a drop meter is installed for each output port used by `SLICE-1` to limit the total excess traffic while allowing bandwidth borrowing with other defined slices. Finally, the flow rules originally installed by the VPLS app are updated to use the created meters.
