Recent Technology in Data Communication
- 1. Amity School of Engineering & Technology 1 EMERGING TECHNOLOGIES IN DATA COMMUNICATION PRESENTED BY: Maaz Hasan Priyanka Yadav Shivani Dubey Kovid Singh
- 2. Amity School of Engineering & Technology CONTENTS 2 • Technology in terms of Data Communication • Cloud Computing • Voice Over IP • 4G LTE • Fibre Distributed Data Interface (FDDI)
- 3. Amity School of Engineering & Technology • Technology in communication can be broadly defined as the use of techniques that can make transfer of data from one node to other in a viable, secure, quick and economically sound manner. • This need can be satisfied by introducing a new technology in the market or improving the prevailing Technology. 2 TECHNOLOGY IN TERMS OF DATA COMMUNICATION
- 4. Amity School of Engineering & Technology CLOUD COMPUTING 4
- 5. Amity School of Engineering & Technology CLOUD COMPUTING 3 • In computer networking, Cloud Computing is computing that involves a large number of computers connected through a communication network such as the Internet, similar to utility computing.
- 6. Amity School of Engineering & Technology CLOUD APPLICATIONS 6
- 7. Amity School of Engineering & Technology 7 • Controlled Cloud • Public Cloud • Hybrid Cloud • Distributed Cloud • Community Cloud • Private Cloud DEPLOYMENT MODELS OF CLOUD COMPUTING
- 8. Amity School of Engineering & Technology 8 • Several deterrents to the widespread adoption of cloud computing remain. Among them, are: reliability, data security, costs, regulations and legal issues, performance, migration and issues of privacy. • The cloud offers many strong points: infrastructure flexibility, faster deployment of applications and data, cost control, improved productivity, etc. THREATS AND OPPORTUNITIES TO CLOUD COMPUTING
- 9. Amity School of Engineering & Technology CLOUD COMPUTING: A CASE STUDY 9
- 10. Amity School of Engineering & Technology VOICE OVER INTERNET PROTOCOL(VoIP) 10
- 11. Amity School of Engineering & Technology VOICE OVER IP 11 • Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks. • Components of VoIP: IP telephone. Media gateway controller.
- 12. Amity School of Engineering & Technology BASIC IDEA BEHIND VoIP 12 • Continuously sample audio. • Convert each sample to digital form. • Send the resulting digitized stream across an IP network in packets. • Convert the stream back to analog for playback. • Before the procedure above, the system must handle call setup.
- 13. Amity School of Engineering & Technology NEED FOR IP TELEPHONY 13 • Economic (uses internet, IP routers). • Further savings. • Not only voice but also video is transmitted using similar concepts. • Spreads at a fast pace. • Independent – no geographical restriction.
- 14. Amity School of Engineering & Technology 14 VoIP: A CASE STUDY Tabarka studio saves with Nextiva’s VoIP phone systems: • With Tabarka legacy systems only two employees could be on the phone at a time. • Nextiva stepped in to offer it’s hosted services which not only reduced phone call cost by 60 per cent.
- 15. Amity School of Engineering & Technology 15 4G LTE
- 16. Amity School of Engineering & Technology LTE refers to Long Term Evolution. 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. 16 4G LTE 4G LTE 3G 2G 1G 0G
- 17. Amity School of Engineering & Technology FEATURES OF 4G LTE 17 • Enhanced mobile gaming. • Faster browsing and downloading rates. • Low data transfer latencies. • Broadband access in remote locations. • Simplified architecture. • LTE infrastructure can deliver services such as mobile and can prove to a competitor to DTH based TV broadcast.

- 19. Amity School of Engineering & Technology 19 HOW 4G LTE WORKS
- 20. Amity School of Engineering & Technology FIBER DISTIBUTED DATA INTERFACE(FDDI) 20
- 21. Amity School of Engineering & Technology FIBER DISTRIBUTED DATA INTERFACE 21 • A Ring Network. • Consists of two Rings i.e. Primary and Secondary. • FDDI local area networks can support thousands of users. • Capacity extended to 200Mbps.
- 22. Amity School of Engineering & Technology COMPONENTS OF FDDI 22 Concentrator Ring Optical Fibre Cables
- 23. Amity School of Engineering & Technology ADVANTAGES OF FDDI • Real-time allocation of network bandwidth. • Wide array of different types of traffic. • Fault-tolerant. • Wrap, when the wiring fails. • Prevent ring segmentation. 23
- 24. Amity School of Engineering & Technology APPLICATIONS OF FDDI • Office automation at the Desktop. • Backbone for Factory Automation. • Backend data center Applications. • Campus LAN interconnection. • Interconnection of Private Branch Exchanges(PBXS). • Integrated transport for Multimedia Applications. 24
- 25. Amity School of Engineering & Technology 25 CONCLUSION • Technology in Data Communication should meet 4 standard conditions i.e. viable, quick, secure and Economically sound. • Cloud Computing is a computing by which data can be retrieved by any device connected on the cloud. It is platform independent and ensure easy way of Data Communication. • VoIP refers to delivery of voice and multimedia sessions through Internet Protocols. It has can reduce call costs by 60%. • 4G LTE is high speed communication that is used in market to provide ultra broadband internet access. • FDDI is a Dual Ring Network that is used for communication over LAN with data rates within 100-200 Mbps.
