11 Transformation To Unified Triple Play Service Delivery2 Triple Play Service Delivery Requirements Services Separated, Packet Forwarding Voice 1 Optimal Cost Structure 2 Triple Play Legacy HSI Service Reach, Bandwidth 3 “Always-on” Guaranteed QoS 4 IPTV & Video

12 Transformation To Unified Triple Play Service Delivery2 The utilization of distinct transport architectures per service necessitates the usage of different encapsulations and packet forwarding. Therefore isolation can be translated as separate packet forwarding and routing per service type. That can be enable through the use of distinct IEEE (VLAN) for the different services. 1 Services Separated and Packet Forwarding Solution

14 Transformation To Unified Triple Play Service Delivery2 This can, however, be solved by widening the bandwidth of access networks Service Reach, Bandwidth Solution 3

15 Transformation To Unified Triple Play Service Delivery2 Bandwidth is optimized by performing multicast packet replication throughout the network Service Reach, Bandwidth Solution 3

16 Transformation To Unified Triple Play Service Delivery2 IPTV and VoD services need high bandwidth. Depending on the compression and coding technology. More compression means less bandwidth requirement, but also less details for the image. Here is the Trade-off Service Reach, Bandwidth Solution 3

17 Transformation To Unified Triple Play Service Delivery2 Nowadays there are several mechanisms available. The most common QoS techniques include the following . IEEE 802.1p/Q standards, MPLS (Multi-Protocol Label Switching). DiffServ (Differentiated Services), RSVP (Resource Reservation Protocol). The Differentiated Service (DiffServ) architecture is preferred over “Hard Quality of Service” (QoS) architecture. Moreover it applies perfectly to triple play, as it satisfies differing QoS requirements. DiffServ functionality that is to classify packets by means of a DiffServ code point (DSCP) and implement corresponding per-hop behavior. 4 “Always-on” Guaranteed QoS Solution

38 5 Conclusion

39 In this project, it is found from the initial system test that the efficient transmitting is achieved by using multicast technology with use the more active compression formatting MPEG-4. Also, the link congestion must be avoided at all costs, and links should operate at 75% of their total capacity (25% availability), in order to avoid Triple Play services degradation, then they should program ADSL network upgrade, in order to decrease their network bandwidth availability and maintain QoS. In order to maintain a standard quality for delivering Triple Play services to customer and keeping his satisfaction with the current recommendations follow ITU-T G.114 and the Y.1541 QoS for PLR, end-to end delay and jitter, the channel bandwidth for system performance over WiMax at 3.5GHz frequency bands should be chosen between 10 and 20MHz. The work shows the variation in the WiMax network performance with varying pathloss models deployed over suburban areas of terrain types varying from hilly terrain with moderate to heavy tree density and then to flat terrain with light tree density for Triple Play services. 5

40 Today, Wi-Fi network offers mobility, while WiMax offers a long-distance backhaul and last-mile solution. The best solution is combination of the two. From our simulation results, it is observed that the scenarios in which the Triple Play services are deployed will affect the performance of the applications when the number of users increase and the overall WiFi link performance degrades. Finally, the work has been done over NGA networks to open a new area of future research. Whereas it is expected wired broadband access networks to continue to evolve toward common general-purpose platform architecture. Therefore, it is expected wireless networks to remain heterogeneous. The inherent scarcity of radio frequency spectrum emerges as the key reason for this prediction. 5
