To summarize, DiffServ provides differential forwarding treatment to traffic, thus enforcing QoS for different traffic flows. Hossam Moustafa. There are four different scenarios being tested which are: Conclusions The simulation results show that the performances of traffic engineering parameters in MPLS networks is much better as compared to traditional IP networks. Davie, S.
When used together, Diffserv provides the Standardized QoS mechanisms and MPLS provides routing techniques increasing the network resource optimization and providing traffic engineering.
In Diffserv, the ingress router classifies the packets and then marks them with the corresponding DSCP.
The intermediate routers use PHB to determine the scheduling treatment and drop probability for each packet . Figure 2, shows the network topology used in this experimental study. The experimental study was divided into two parts, first part only shows how MPLS improves the overall performance of the network and the second part inserts the DiffServ and the integration of DiffServ and MPLS together.
Network Model 5. There are two scenarios being tested which are: FTP traffic was set to low load and best effort type of service, where files are bytes and time between client request is exponentially distributed with mean seconds. Low resolution video starting at 10 fps frames per sec arrival rate and x pixels are used.
For voice traffic, the voice encoder scheme is G. Background traffic has been specified at the links. The primary purpose of the background traffic is to model the effect of general traffic in the network on selected traffic of interest. Video Simulation In this project, three classes of service are provided: The EF traffic has an optimum bandwidth guarantee with low latency, low jitter and no packet loss.
Video traffic was defined as the EF service in the simulation. The same topology used only voice station replaced by http station. FTP traffic was set to high load and best effort type of service, where files are bytes and time between client requests is exponentially distributed with mean seconds.
There are four different scenarios being tested which are: All the traffic used the shortest path A-E-D and exceeded its bandwidth capacity, while the longer path was under-utilized.
The throughput increased at the links as the voice increased its traffic rate with time. Packets get dropped and delayed as buffers overflow because the resources in the network cannot meet all traffic demand. Voice Results 6.
Figure 3: Voice Throughput 6. In MPLS, the labeling of packets has provided faster processing rate at the routers as compared to the conventional IP, where address matching procedure is carried out.
Figure 4: Figure 5: Voice Jitter 6. Video Results 6. Video throughput Figure 6 displays the video throughput of the four scenarios. And the MPLS used to distribute the traffic on the network resources. Therefore, DiffServ-MPLS demonstrated the advantage to utilize these two attributes in offering the lowest end-to-end delay for video traffic even though at high traffic flow. Video throughput Figure 7: When TCP detects network congestion, the TCP source undergoes congestion control phase and slows down the transmission rate.
Moreover, it can be seen from Fig. Figure 8: HTTP throughput 7.
Conclusions The simulation results show that the performances of traffic engineering parameters in MPLS networks is much better as compared to traditional IP networks. MPLS satisfies the first condition, i. References  M. Tanvir and A. Le-Faucheur, B. Davie, S. Davari, P. Vaananen, R. Krishnan, P. Cheval and J. Rosen, A.
