Introduction:
Asynchronous Transfer Mode (ATM) is a high speed network technology which is designed to support both voice and data communications. It was initially developed to meet the needs of the Broadband Integrated Services Digital Network, in the late 1980s and designed to combine telecommunication and computer networks. It was originally designed for use in public networks, but now has also been deployed as a major backbone technology for private networks.
ATM uses asynchronous time-division multiplexing to encode and transfer data in the form of cells or packets of a fixed size. It is normally used by Internet service providers on their private long-distance networks. It operates at the data link layer (Layer 2 in the OSI model) over either fiber or twisted-pair cable. It uses a connection-oriented model in which a virtual circuit must be established between two endpoints before the actual data exchange occurs. These virtual circuits may be dedicated connections that are usually preconfigured by the service provider, or “switched”, i.e. set up on a per-call basis using signaling and disconnected when the call is terminated.
ATM basically is a cell-relay technology which divides upper-level data units into 5...

In this lab, we used Transmission Control Protocol (TCP) which is a connection oriented protocol, to demonstrate congestion control algorithms. As the name itself describes, these algorithms are used to avoid network congestion. The algorithms were implemented in three different scenarios i.e. No Drop Scenario, Drop_Fast Scenario and Drop_NoFast Scenario.
After compression, the structure data, audio and video must be multiplexed. A number of compressed TV signals are combined by a multiplexer and put unto a shared transition medium. This is done by one of the two possible kinds of multiplexers that result in either a transport or a program stream, which is suited for secure transmission paths since it can contain large amounts of information. In addition multiplexing can be done using various methods. Time division multiplexing allocates a distinct time interval for each channel in a set; with the help of synchronization and a fixed interval order the channels take turns using the common line.
National Broadband Network is a fibre and wireless based communication that would provide a speed of about 12 MB per second. It is estimated that 93per cent of the project will be fibre to node while the remaining 7per cent will be through wireless means. Telstra is the current broadband provider and coalition Rudd government of Liberal and National party has decided to provide an open acces data network to all citizens so that the fixed line customers of Telstra will migrate to the Local Access Network of NBN Co Limited. It is expected that after the establishment of NBN, the government will keep upgrading the services. The first goal of the setting of NBN is to be the only broadband provider in Australia. The Layer 2 wholesale will be the broadband for personal and professional customers. According to the financial agreement between the NBN Co and Telstra, NBN is ...
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
Last phase is data exchange. In data exchange, client and server exchanges the data by creating one or more data channels. In each channel, flow is control using window space available. There are 3 stages of the life of the channel: open channel, data transfer and close channel. One the channel is open by either of the party, data is transferred and then channel is closed by either of the party [3].
ADC Telecommunications (ADCT) is a communication equipment manufacturer located in Minneapolis, Minnesota, USA. Since 1952, the company has successfully weathered the tumultuous transformation process of technology. Today, ADC Telecommunications exclusively focuses on manufacturing computer-networking equipment. Increasing demand for fiber optic transmission systems like asynchronous transfer mode (ATM), synchronous optical networks (SONET) and most wireless communications systems, provide significant opportunities for ADCT. The company currently focuses on enabling communications service providers to deliver high-speed services to residential and commercial customers. The following is an annual analysis of ADCT's financial ratios of years 1995-1999.

In telecommunication signaling within a network or between networks, synchronous signals are those that occur at the same clock rate when all clocks are based on a single reference clock. Synchronous communication requires that each end of an exchange of communication respond in turn without initiating a new communication.
Asynchronous Transfer Mode (ATM) is the mostly implemented in high speed networks. ATM is the transmission system for CCITT's next-generation ISDN, Broadband ISDN (B-ISDN). B-ISDN is designed to provide subscriber communication services over a wide range of bit rates from megabits to several gigabits.
Nortel Networks' state-of-the-art DMS-100 Wireless product is a multi-functional switching system that integrates the industry's most respected DMS-100/200 (local/toll) wireline and DMS Mobile Telephone Exchange (MTX) digital wireless switching systems onto a single hardware platform. The DMS-100 Wireless offers a flexible and cost effective way for a service provider to establish a single point of presence in both traditional wireline and wireless markets, as well as new data and internet telephony markets. And, by delivering new integrated customer services such as a single voice mail box, one number capabilities, and feature transparency, service providers can pursue new revenue opportunities, increase customer satisfaction, and establish a market presence as a technology leader.
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
