The Small PC-Network model consists of two routers connected via abottleneck link, which can transmit 20 packets per second. Eachrouters serves several hosts (from 18 to 22) which are Poissonsources with a rate of 1 packet per second. So the inter-arrival timeof the sent packets are exponentially distributed.
Both routers have a limited queue size, which is configurable and part of theevaluation. The queues are simple FIFO queues, where packets receivedwhile the queue is full, are simply dropped. The packet loss should beevaluated over various queue sizes and various host numbers (18, 20,22). All packets are assumed to have the same size, so that servicetime is also constant.
OMNet++ is a public-source simulation environment, which main goal isthe simulation of communication networks. However its design is quiteopen, which enables also other target applications. It has asophisticated GUI support and common used models like IPv4, IPv6,Ethernet, MPLS etc. are available. OMNet++ is free for academic andnon-profit use, however for commercial use a license must be obtained.
The network simulator 2 (ns-2) is a frequently used discrete eventsimulator mainly for networking research. For implementing the model,the object orientated extension of TCL, OTcl is used. Thefunctionality of modules can also be coded in OTcl or for speedoptimizations in C++. ns-2 includes the most common networktechnologies and applications, for very easy and fast networkspecification and simulations.
QualNet is the first commercial simulator in this comparison. It isbased on GloMoSim developed at the University of California, LosAngeles (UCLA). GloMoSim uses the Parallel Simulation Enviroment forComplex Systems (PARSEC) for basic operations.
QualNet alsohas a graphical user interface for creating the model and itsspecification. So it is by far easier to specify small to mediumnetworks by using the GUI compared to specifying all connections in aspecial model file manually.
QualNet is a network simulator targeting at wireless solutions,however it also has support for wired networks. Its environment andlibrary is very sophisticated, which makes it very easy to simulate areal network with QualNet. This however makes the simulation oflogical networks a little bit more difficulty, but it is possible aswell.
SimPy is an extension for the script language Python for easydiscrete event simulation. The advantage is a easy modifiable languagefor discrete event simulation without any restrictions, however thesimulation performance is lower, since Python is still a scriptlanguage, which is interpreted.
It is released under the GNU Library or LGPL license, which enableseveryone free use of the package. Since its an extension for Python,its available on every system, where Python is running which includesLinux and Windows.
Entprise Dynamics is a simulator for industrial processes. It has avery nice GUI for developing the model as well as simulating itafterwards. The core modules can be extended by using the ownscripting language 4DScript. Since its main target is not networksimulation, its performance is not well optimized for this task, butit is still possible.
AnyLogic is another commercial product. However it is the onlysimulator here, which supports discrete, continous and hybridsimulation methods. However only the discrete part was used for thisevaluation. The GUI is very sophisticated enabling fast model designas well as interactive experimentation.
The model in OMNet++ was designed modular. So a router module wascreated consisting of a FIFO-queue with n input values and one output,and a sink for incoming messages over the bottleneck. Then a networkwas created consisting of 18-22 hosts and one router, and twoinstances of this network was connected over the bottleneck link.
The modules for the FIFO-queue, the random traffic generator and thesink were derived from modules of the OMNet++ examples. The FIFO-queuewas made finite with counters for incoming and dropped packets. Thesending functions of the FIFO-queue was also modified, to send only,if the bottleneck link is not currently busy.
Overall this were small and easy changes, however it needed quite sometime to work into the system of the simulator, to understand all partsof it. Overall it maybe took the longest to develop model for OMNet++but the comfort of the TK GUI then was one of the best.
The implementation was taken from [1]. Thisimplementation did not result in the right values, since theimplementation of a ns-2 queue is somewhat weird. Effectively ns-2 queueswith one element can never hold any item, and will always produce 100%packet loss, which is not the correct behavior. A look into the ns-2sources revealed, that the queue size in ns-2 always need to be onebigger than usual, to result in the same behavior.
The hosts were simulated by using UDP-agents directly connected to therouter. This agent produces Poisson traffic by using theTraffic/Expoon module. The queue monitors collect the statistic of thetwo router queues, and about received and dropped packets. With thisvalues the packet loss will be computed after finishing the simulation.
Here in QualNet only one side of the Small PC-Network wassimulated. Actually 22 hosts were modeled, with two routers. All 22hosts are connected to the first router, and between the two routersthere is the bottleneck link. Depending on the number of hosts toparticipate, 18, 20 or 22 traffic generators are used as applications,which sends fixed sized packets from the hosts to the secondrouter. The link between the hosts and the first router where modeledas 100 MBit/s links, while the bottleneck link had a bandwidth of80040 Bit/s. The additional 40 Bit/s were needed since QualNetrequires a link level header to be used (with greater than 0 bits). Atwo bit link level header was used over the bottleneck link. So for 20 Packets/s this results in additional 40 Bit/s.
