Fix a bug when processing Flow Entry notifications and updating the locally stored FlowEntries. Previously, even if a Flow Entry wasn't updated, it could trigger multiple writing of a FlowPath to the Database. Now we explicitly check whether the locally stored FlowEntry is actually updated. As a side-effect of the above fix now we have to: (1) Create a copy of a FlowEntry inside FlowManager.flowEntriesPushedToSwitch() before modifying it and pushing it into the Datagrid (2) We have to explicitly check whether all Flow Entries have been installed into the switches before writing a FlowPath to the Graph DB.
ONOS (Open Networking Operating System) is an experimental distributed SDN OS. Currently, it is under active development. ONOS was announced and demonstrated at ONS'13.
Apache 2.0
http://wiki.onlab.us/display/Eng/ONOS+Development+VM
Install custom jars and dependencies (needs to be run only once)
$ ./setup-local-maven.sh
Cleanly build ONOS
$ mvn clean $ mvn compile
NOTE: installing maven for the first time may switch java version from 1.7 to 1.6. This might prevent Cassandra to run.
Zookeeper
Download and install apache-zookeeper-3.4.5: http://zookeeper.apache.org/releases.html
Edit file (ONOS-INSTALL-DIR)/start-zk.sh and set variable "ZK_DIR" to point to the Zookeeper directory.
Cassandra
Download and install apache-cassandra-1.2.4: http://cassandra.apache.org/download/
Edit file (ONOS-INSTALL-DIR)/start-cassandra.sh and set variable "CASSANDRA_DIR" to point to the Cassandra directory.
[See below for information how to run ONOS with Embedded Cassandra]
Start Zookeeper
$ cd (ONOS-INSTALL-DIR)/ $ ./start-zk.sh start ## Confirm Zookeeper is running: $ ./start.zk.sh status
Start Cassandra
$ cd (ONOS-INSTALL-DIR)/ $ ./start-cassandra.sh start ## Confirm Cassandra is running: $ ./start-cassandra.sh status
Start ONOS
$ cd (ONOS-INSTALL-DIR)/ $ ./start-onos.sh start ## Confirm ONOS is running: $ ./start-onos.sh status
Start ONOS REST API server
$ cd (ONOS-INSTALL-DIR)/ $ ./start-rest.sh start ## Confirm the REST API server is running: $ ./start-rest.sh status
Start Zookeeper
$ cd (ONOS-INSTALL-DIR)/ $ ./start-zk.sh start ## Confirm Zookeeper is running: $ ./start.zk.sh status
Start ONOS and Cassandra embedded
$ cd (ONOS-INSTALL_DIR)/ $ ./start-onos-embedded.sh start ## Confirm ONOS is running: $ ./start-onos-embedded.sh status
Start ONOS REST API server
$ cd (ONOS-INSTALL-DIR)/ $ ./start-rest.sh start ## Confirm the REST API server is running: $ ./start-rest.sh status
Maven is used to build and run ONOS. By default, maven tries to reach the repositories. The '-o' option can be given to the 'mvn' command to suppress this behavior. The MVN environmental variable can be used to set additional options to the 'mvn' command used in ONOS.
Example: Running in offline mode
$ env MVN="mvn -o" ./start-onos.sh start
