Abstract
Broadband access is the buzzword of today, the market is for fast Internet access, distance learning, multimedia downloads, interactive gaming and video services which can be provided by wire line and wireless broadband technologies. With this the hunt for killer services comes into act i.e., TRIPLE PLAY. These services will also help corporates in cutting costs and improving bottom lines. This presentation is about the Triple Play—VOIP, IMS, FMC, WiMAX and IPTV.


Introduction of Triple Play

Triple play technology is nowadays considered as an indisputable trend. The differentiated service architecture is preferred over "hard quality of service" (QoS) integrated service architecture. Moreover it applies perfectly to triple play, as it satisfies differing QoS requirements. In addition, latest developments in the area of video and audio encoding impose new challenges in content delivery systems. The combination of these three technologies is expected to raise additional QoS related issues. Problems such as full exploitation of available bandwidth and providing adequate QoS to subscribed users by meeting the requirements of all three supported services (video, voice and data) must be addressed. Within this context, the particular paper examines the performance of common packet scheduling techniques used in differentiated service triple play architecture. The performance of priority queuing (PQ), weight fair queuing (WFQ) and weight fair low latency queuing (WFQ-LLQ) schemes is assessed, in order to find the most appropriate solution for the underlying network. The evaluation of the schedulers is based on simulations designed upon real triple play networks, while trace files are used for the simulation of video flows.

We could clearly knew the need for uprising technologies like triple play from the fact that the revenues of the companies which delayed in using these technologies have come down.
• British Telecom
• Retail revenues down 2.5%
• Retail profits down 10%
• Deutsche Telecom
• Domestic revenues down 1.6%
• Broadband/fixed revenues down 3.6%
• France Telecom
• Domestic residential revenues down 1.2%
• Domestic enterprise revenues down 5.4%
• KPN
• Fixed network revenues down 4%
• Business revenues down 9%

Voice over IP (VoIP)

In past the communication process was done by the means of electric circuits which was expensive and took more time for connecting to the respective user. So this VoIP came into existence.
Voice over Internet Protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other packet switched networks. Voice over IP protocols carry telephony signals as digital audio, typically reduced in data rate using speech data compression techniques, encapsulated in a data packet stream over IP.
The ability of VoIP is to transmit more than one telephone call down the same broadband connected telephone line. It’s also a location independent, just by having internet connection we can avail this service.

This is a wonderful information and for me it is really worthy and I also like the information on Triple Play which seems to be very interesting. I am a student of It and I basically need to write different topic every day for my class. You know to go online search topic and again write it in your own words will not be easy. So I am looking for a reading software which can be installed and and feed my topics itself. There are many software but you know to get the best one for me is my goal. I have now come to know about rfid reader which seems to cover my demand, but as my friend told me using feed readers will be no use cause sometimes it gives us too much of feed which is of no use and above all it also let's the virus into your computer. So please do let me know I would be more than happy to know about feed readers and it's advantages and dis-advantages. Here I also knew about triple play technology which is a very important topic for me to share in my class.
