ABSTRACT

Our Project is to implement and study server load balancing in the Software Defined Networking (SDN) environment using Round Robin and Random Policy. The load balancing Policies are run at the SDN Controller. Load balancing is very important concept in Data centers where high availability as well as performance is required.

In this Project we used open source Opendaylight Controller which provides the North Bound interface to

implement the load balancing Policies and also provides the south bound interface to communicate with OpenFlow switches. The entire data center is emulated in the Mininet platform.

During our work on this project we learned about Software defined networking, how it is different from

traditional Networking, we got a greater insight about ODL, Mininet, and OpenFlow vSwitch.

1.10 Server Load Balancing

The main idea of using load balancing is to implement the following three things:- Scalability: Load can be distributed to different servers Manageability: Application can be transferred from one server to another within same

cluster (server group). Availability: To reduce downtime in Production Systems. In our case load balancer service is running on controller which acts as a reverse proxy to distributes network traffic across a number of servers based on predefined polices: Round Robin or Random. Load Balancing in servers can be implemented by two methods:- Stateless: The controller does not keep track of state of servers and will send the information based on policy to server even the particular server is down. State-full: The controller keeps track of state of servers and monitors the state of the related servers.

The sixth flow between H9and a virtual server uses S7-S1-S4-H6; And so on Study if this is the case. If not, record the paths taken. Use iperf traffic generator to generate TCP traffic and measure the delay and throughput. Generate 32 flows with data rate of 20Mbps each. Compare the results with only two servers (says H1 and H2). The idea here is to show that by using more servers, we can use more available network bandwidth, thus reduce the delay and increase the throughput. Compare the delay and throughput between the round-robin and random policies. To accomplish our desired project, we use the following devices and tools:

2.2 Setup 1. Two Virtual Machines each one with Ubuntu 14.04 32 bit 2. Oracle VirtualBox 3. GIT 4. Apache Maven 5. MobaXterm 6. VBox Guest Addition for Linux 7. WireShark 8. Mininet 9. ODL Controller Code

2.2.1: Two Virtual Machines each one with Ubuntu 14.04 32 bit: We need to download Ubuntu with version 14.04 version 32bit and configure it as virtual Machine. We need two machines for our project, one will be used as controller and other will be used for Mininet.

2.2.2: Oracle VirtualBox We have installed our Virtual machines using Oracle Virtual Box. 2.2.3: GIT GIT is open source version control tool; we have used git to get the current version from ODL repository. 2.2.4: Apache Maven.

Apache Maven is the tool used to build Java projects; we have used Apache Maven to build ODL OSGI bundles after downloading them, details are in the installation appendix.

2.2.5: MobaXterm We have used this tool as our ssh client .

2.2.6: VBox Guest Addition: This is an ISO which is helpful to maximize the size of Linux OS while working in Windows 2.2.7: WireShark:



We have used wireshark to analyze open flow packets. This can be configured on Linux and windows both. We have installed version which includes openflow plugin. 2.2.8: MiniNet: This tool is used to emulate the network. 2.2.9: ODL : We downloaded opendaylight(ODL) OSGI bundles using Git and compiled them locally using Maven.

3.2 Implementation: Software tools requirements to install Opendaylight and Mininet. Opendaylight can be installed in more than one way depending on the intention of the future use; also it can be installed on Linux, UNIX and Windows machine. Opendaylight has 03 major releases for now, Hydrogen, Helium and Lithium, we have used current Stable release which is Helium. Also we need to have Java JDK, git and Maven installed on the box before one begins installation of the ODL. Here are the 03 methods one can use to install ODL: 1. Using Karaf 2. Pulling the code from CLI and build locally using Maven. (We have used this method for our Project) 3. Import Code into Eclipse and re-compiling using Maven. 1) Installation Using Karaf This is the easiest way one can install ODL, one needs to be familiar with Karaf commands, this link provides nice introduction to karaf. http://www.liquid-reality.de/display/liquid/2011/02/15/Karaf+Tutorial+Part+1+-+Installation+and+First+application To install ODL on Ubuntu, Opendaylight wiki provides step by step procedure. https://wiki.opendaylight.org/view/Install_On_Ubuntu_14.04 2) Pulling the code from CLI and build locally using Maven. We have followed this procedure in our installation; following are the steps we have followed in our ODL setup. This is specific to Ubuntu. The detailed Procedure is in the Appendix. 3) Eclipse Installation and build the code in Eclipse using Maven. This method is used if one is developer and wants to see the code of all the packages or needs to write new custom application this method should be used; we have imported code in the Eclipse, but havent used it for the Project. Following references can be used to use Eclipse:- https://wiki.opendaylight.org/view/Getting_Started:Eclipse:Installing_Eclipse_on_Ubuntu https://wiki.opendaylight.org/view/GettingStarted:_Eclipse http://networkstatic.net/importing-opendaylight-into-eclipse/ 3.4 Load Balancing Methods Used and VIP VIP (Virtual IP), in server load balancing: VIP acts as the proxy between the external world and the server group. We have demonstrated opendaylight controller load Balancer bundle (org.opendaylight.controller.samples.loadbalancer.internal) two features round robin and random policies. RoundRobin policy: This policy will send traffic to group of servers in orderly manner one after the other Random policy: This policy will select servers randomly based on random algorithm

IListenDataPacket looking at the ARP conversation between an host and the controller. This is an application that show case a possible host tracking mechanism, especially useful in the cases like OpenFlow where the controller can see all the packets if instructed to.

org.opendaylight.controller.forwarding.staticrouting.internal IForwardingStaticRouting ICacheUpdateAware IfNewHostNotify IConfigurationContainerAware

Provide the necessary hooks to inject in the area controlled by the controller, routes to reach traditional IP networks.

org.opendaylight.controller.forwardingrulesmanager.internal IContainerListener ISwitchManagerAware IForwardingRulesManager IInventoryListener ICacheUpdateAware IConfigurationContainerAware IFlowProgrammerListener

Manager of all the Forwarding Rules, this component take case of forwarding rules and is the one that manage conflicts between them.

org.opendaylight.controller.hosttracker.internal ISwitchManagerAware IInventoryListener IfIptoHost IfHostListener ITopologyManagerAware

Track the location of the host relatively to the SDN network.

org.opendaylight.controller.protocol_plugin.openflow.internal IContainerListener IController IDataPacketListen IDataPacketMux IDiscoveryService IFlowProgrammerNotifier IInventoryShimExternalListener IMessageListener

Protocol plugin for OpenFlow 1.0. Include the openflow J library as well the necessary glue logic to adapt to SAL layer along with a discovery mechanism for learning the graph of the OpenFlow network portion.

Pull in our setup. Following are the steps:

Move the desired directory, in our case it is user $HOME

git clone https://git.opendaylight.org/gerrit/p/controller.git

saif@saif-SDN:~$ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/master/settings.xml > ~/.m2/settings.xml

saif@saif-SDN:~$ cd controller/

saif@saif-SDN:~/controller$ sudo git checkout stable/helium

Checking out files: 100% (3975/3975), done.

Branch stable/helium set up to track remote branch stable/helium from origin.

Switched to a new branch 'stable/helium'

saif@saif-SDN:~/controller$

mvn clean install DskipTests
