Performance evaluation of a portable PABX system through developing new bandwidth optimization technique

Now is the age of information technology. World is advancing day by day. At present in this progressing world communication from one place to another has become so easy, less costly, and faster. This modern life is almost impossible with the help of these communication technologies. People need to talk, need to share data, need to express their emotion from long distance. So they need to use technologies to communicate with one another. But nowadays people prefer video calling more than voice calling. They often used video calling most instead of voice calling. Some software like Skype, Yahoo, Gtalk, Msn is used for voice and video call. But these software uses high capacity of bandwidth and a big amount of internet speed. Thinking of this, a flexible portable video calling PABX PC to PC and PC through different smart phone system established that operates with local LAN bandwidth consist of three limited equipments- 1)Server 2)Soft phone 3)Web cam through the network nodes. This system can be implemented on telecommunication sectors like call center, mobile phone customer care center etc. It can also be implemented on security issues like CCTV cameras. The system is implemented through new BW optimization technique which is more efficient in terms of time delay, number of packets and memory complexity. After evaluating the simulation, it is assured that this system is better than other existing systems which are available in market.
