+# Lighty-TransportPCE Controller
+
+This project starts [TransportPCE](https://git.opendaylight.org/gerrit/#/admin/projects/transportpce) without karaf framework.
+
+## Build & Run
+* Make sure you have JDK8 or later installed
+* Make sure you have [maven 3.5.0](https://maven.apache.org/download.cgi) or later installed.
+* Make sure you have proper [settings.xml](https://github.com/opendaylight/odlparent/blob/master/settings.xml) in your ``~/.m2`` directory.
+
+#### Before compiling Lighty-TransportPCE
+Make sure upstream projects are compiled locally and stored in local ``~/.m2/repository``:
+1. compile __transportpce/master__
+```
+git clone https://git.opendaylight.org/gerrit/transportpce && (cd transportpce && curl -kLo `git rev-parse --git-dir`/hooks/commit-msg https://git.opendaylight.org/gerrit/tools/hooks/commit-msg; chmod +x `git rev-parse --git-dir`/hooks/commit-msg)
+cd transportpce
+```
+Before compilation, make sure that deviations are not present in models:
+```
+transportpce/ordmodels/network/src/main/yang/org-openroadm-otn-network-topology@2018-11-30.yang
+transportpce/ordmodels/network/src/main/yang/org-openroadm-network-topology@2018-11-30.yang
+transportpce/ordmodels/network/src/main/yang/org-openroadm-network@2018-11-30.yang
+```
+After deviations are removed from models, compile the project.
+```
+mvn clean install -DskipTests
+```
+2. compile __lighty-core/10.0.x__
+```
+git clone https://github.com/PantheonTechnologies/lighty-core.git
+cd lighty-core
+git checkout 10.0.x
+mvn clean install -DskipTests
+```
+#### Compile Lighty-TransportPCE
+* Project is build using maven command:
+```
+cd ../lighty
+mvn clean install
+```
+* After project build is done, use binary package to run the TransportPCE controller.
+```
+cd target
+unzip lighty-transportpce-10.0.1-SNAPSHOT-bin.zip
+cd lighty-transportpce-10.0.1-SNAPSHOT
+./start-controller.sh
+```
+
+## TransportPCE lighty.io - karaf comparison
+
+### Application Boot test
+This test compares TransportPCE application on lighty.io and karaf.
+After TransportPCE is started, performance is measured using [visualvm](https://visualvm.github.io/) tool.
