Asynchronous Transfer Mode Description and Development Essay

Asynchronous Transfer Mode Description and training - Essay Example automated teller was originally conceived as a solution for completely integrating the inbuilt set of communication technologies, starting from the Local Area Network to the IP based systems and the broad spate voice and data communication systems. automatic teller machine was proposed as the final and ultimate protocol to take lot of all the requirements of all communication systems in the world. However, it was found that automated teller could satisfy only some of these interchangeable ADSL could take away full use of it. ATM was not used in its original form on the other devices. The best features and proposals of ATM were incorporated in a number of other standards that came about, typically, MPLS kind of systems. However, ATM has taken a rebirth in terms of the standards that are currently being developed IEC 62365 which provides for twain audio and video over IP using ATM technologies.The aim of this paper is to present the asynchronous transfer mode as a standard protocol, its description and development over a catch of time. The paper will also look at the places were this is being employed and to what extent these were successful in implementing the systems that are needed for the exploiters.Asynchronous Transfer mode systems integrate Voice, Video and Data. Since it is connected oriented technology, iodine packet with the same source and destination will travel through the same route. This employs best grounds delivery system which would enable performance and bandwidth on demand. Figure 1 Aimed at providing best helping (IEC, 2005)ATM as per the standards defined would employ connection oriented, packet-like makeing and multiplexing model. It starts by defining the fixed size cellular phone that comprises of 48 bytes of data and 5 bytes of header together making up the 53 bytes of cell information. ATM is fundamentally connection oriented. Therefore, it does multiple xing and reserves a route for a specific user on getting a request from the user. Multiplexing such lines over a network either from a user to a destination or from one switch to another would optimize the usage of the network to a great extent. This would save the cost of switching when requests are made one after the other and switch keeps changing the route. ATM also specifies a number of standards on how an user would get connected to an ATM network depending upon the upper berth of the network. ATM to User interface standards are governed by the ATM UNI standards.ATM has the interest three grades1. The physical layer2. ATM Layer3. ATM adaptation layerThe physical layer consists of various media that make up the transmission system, which would eventually add from kilo small-arms per second to gigabits per second. The ATM layer defines the cells that make up the data transfer along with the other components multiplexer that would switch the cell to the specific route that it should take, switches that would transmit data over a high speed switching hardware so that the transmission speed is achieved and finally have necessary software or hardware to take care of the issues that concern the commerce and do traffic management. In the ATM adaptation layer, four different types of data transfer is provided for the ATM system.AAL Type 1Constant bit rate servicesAAL Type 2Variable bit rate servicesAAL Type 3 / 4Connectionless services and data protocolsAAL Type 5 steep Speed
