No matter if it’s called Carrier Ethernet, Metro-Ethernet, or Business Ethernet the premise is pretty a great deal the similar. While 100-megabit Ethernet and other higher-speed networks can offer comparable bandwidth, only ATM can supply the QoS guarantees needed for true-time telephony, VCR-high quality video streaming, CD-quality sound, smooth videoconferencing, and other delay-sensitive voice and video applications.
In the instance (from Asynchronous Transfer Mode Techonology by Martin de Prycker), we see that a virtual path is established among nodes A and C. Two cells, with a VCI of three and 4 and each obtaining a VPI of 9 are routed at node A to the path leading to node C, purely by virtue of their VPI.
ATM is struggling to adapt, nonetheless, to the speed and targeted traffic-shaping specifications of convergent network technologies, specifically with respect to the complexity connected with Segmentation and Reassembly (SAR), which is the supply of a considerable performance bottleneck.
Now this convergence of technologies could lead to the very same mobility and speed that has been associated with the digital planet to the creation of physical objects, basically combining and revolutionizing the design and manufacturing process.
It is essential to note that LANE does not attempt to emulate the actual MAC protocol of the precise LAN concerned (that is, CSMA/CD for Ethernet or token passing for IEEE 802.five). LANE requires no modifications to higher-layer protocols to allow their operation more than an ATM network.
