What Is Asynchronous Transfer Mode - Definition, Application And Examples.
Well ATM particularly stands for asynchronous transfer mode and can be defined as a typically cell based switching technique which specifically makes the use of asynchronous time division multiplexing that enables encoding of specific data into definite sized cells or cell relay and provides particular data link layer services which specifically run on OSI Layer 1 physical links. Well most often people confuse it with packet switched networks like the Internet Protocol or Ethernet where different sized small packets are used for data transfer.
ATM or asynchronous transfer mode typically possesses properties of both types of networking, meaning it can be used in both circuit switched as well as packet switched networking which may act as the best means of a wide range of data transfer. Asynchronous transfer mode-technology can easily be used for both LAN and WAN connections. It has the potential of providing a data transfer speed of up to 2.5 GBps which easily helps to enable high bandwidth distributed applications. It easily provides high transmissions seeds for both LAN and WAN connections by simply enabling distributed applications of high power which previously could only be used in LAN connection but failed to work on WAN networks.
It uses the basic techniques to switch between single integrated switching mechanisms. As far as traffic is concerned asynchronous transfer mode specifically uses virtual network for driving traffic within different locations.
A Guide to Asynchronous Transfer Mode.
The asynchronous transfer mode, sometimes also known as ATM, is a transferring technique based on cell. This comprises loads of terrific features and is compatible with both local area and wide area network connections.
Asynchronous transfer mode might be described as a characteristically cell based transferring system that exclusively takes advantage of multiplexing by asynchronous division of time. This makes it possible to encode the specific information into specific sized cells and cell relays and offer an exclusive data linkage layer service that expressly rely on an OSI Layer 1 physical connection. But, more often than not, people mistake asynchronous transfer mode for a packet switched system such as the IP or Ethernet, which basically rely on small packets of different sizes for transfer of data.
This means that it can be utilized in a switched circuit mode in addition to the packet switched system, which might double up as an ideal way of transfer for a wide variety of data. Asynchronous transfer mode is also really appropriate for an instantaneous and synchronized media transfer. The system that is mainly utilized in this particular method of data transport largely relies on the connection. Asynchronous transfer mode technology can be utilized without difficulty in both local and wide area network connections. This has many unique features and applications. It can be possibly used to provide a data transfer rate of around 2.5 GB/s which helps in effortless running of distributed functions on high bandwidths. This is mostly helpful in video streaming methods used for video conferencing.
The asynchronous transfer mode offers better transfer seeds for LAN or WAN links easily by merely enabling the distribution of high powered applications. It draws on the essential systems to alternate between various switching systems. This generally makes use of virtual networks to gain more traffic.
In conclusion, asynchronous transfer mode is a mode of data transfer.
Security of Asynchronous Transfer Mode and Multi Protocol Label Switching.
Security has several interpretations. There is another interpretation of security that relates to how well a network ensures that only those parties who are configured to exchange certain information can in fact do so. Both ATM and MPLS rely on this security by configuration paradigm. For example, when properly configured, only the source and destination interfaces in a provider network for an ATM virtual connection can receive cells sent by customer devices sent on these interfaces.
Within a service provider network, it may be possible to tap into an information stream, and even to modify it. Here, MPLS and ATM rely on the physical site security of a provider or enterprise to make such actions difficult, if not impossible. Since configuration and physical site security have the potential for human error and compromise, this is why security experts recommend cryptographic protection for sensitive information.
When used as an infrastructure for support of other services, MPLS and ATM have an additional level of configuration security. By not opening up the routing function, the network is protected from external sources of instability. In a permanent connection service, excluding signaling add further protection as well.
Finally, there is an aspect of security regarding how resilient a network and its management system(s) are to attacks by those who would strive to disrupt or deny service. This begins with configuration security, and restriction of routing, and in some cases signaling, interfaces to only those network elements that are trusted. However, management systems for asynchronous transfer mode (ATM) as well as MPLS based networks are often Transmission Control Protocol/Internet Protocol based, and hence the problem of securing the network in these cases centers on securing access to the management network and not the network elements themselves.
