OMNET++ SDN PROJECTS
SOFTWARE DEFINED NETWORKING PROJECTS USING OMNET++ SIMULATOR
OMNET++ SDN PROJECTS approach to networking that eliminates the complex and static nature of legacy distributed network architectures. This is achieved through the use of a standards-based software abstraction between the network control plane and underlying data forwarding plane in software defined networking projects, including both physical and virtual devices.
- Completed OMNeT++ SDN PROJECTS 67%
- On-Going OMNeT++ SDN PROJECTS 31%
Features of SDN:
- A centralized controller and view of the network.
- Separation of the control plane from the data plane.
- Programmability of the network by external applications.
Advantages of SDN;
- Reduced downtimes.
- Cost reduction.
- Managing virtual packet forwarding.
- Isolation and traffic control.
- Central networking management tool.
- Overhead reduction.
- Physical vs virtual networking management.
Research challenges on SDN:
- Controller placement.
- Improve network performance.
- Low level interfaces.
- Scalability
- ASIC and CPU limitations.
Sample code for SDN:
void OFA_controller::handleMessage(cMessage *msg)
{
if (msg->isSelfMessage())
{
cMessage *data_msg = (cMessage *) msg->getContextPointer();
delete msg;
processQueuedMsg(data_msg);
if (msg_list.empty())
{
busy = false;
}
else
{
cMessage *msgfromlist = msg_list.front();
msg_list.pop_front();
char buf[80];
sprintf(buf, ” %d pakets in queue”, msg_list.size());
getParentModule()->getDisplayString().setTagArg(“t”, 0, buf);
std::list::iterator i = msg_list.begin();
while (i!=msg_list.end())
{
EV << (*i)->getFullPath() << endl; i++; } cMessage *event = new cMessage(“event”); event->setContextPointer(msgfromlist);
scheduleAt(simTime()+serviceTime, event);
} }
else
{
if (busy) {
msg_list.push_back(msg);
}
else
{
busy = true;
cMessage *event = new cMessage(“event”);
event->setContextPointer(msg);
scheduleAt(simTime()+serviceTime, event);
}
}}
