Asynchronous Transfer Mode (ATM) is a switching technique that uses fixed-sized cells to encode data for transmission over telecommunication networks. ATM can handle both traditional high-speed data traffic as well as real-time, low-latency content like voice and video. It provides services at the data link layer and has similarities to both circuit switching and packet switching. ATM is commonly used for wide area networks and some DSL implementations also use ATM technology.
ATM is a packet-oriented transfer mode. It allows multiple logical connections to be multiplexed over a single physical interface. The information flow on each logical connection is organized into fixed-size packets, called cells. As with frame relay, there is no link-by-link error control or flow control.

Asynchronous Transfer Mode ATM is the cell relay protocol designed by ATM Forum and adopted by the ITU-T. Cell, a small fixed size block of information with asynchronous TDM ensures high speed real time transmission with efficient and cheaper technology. Instead of user addresses, it uses virtual circuit identifier and virtual path identifier, which can be repeated at unrelated locations. This technology ensures connectivity to much more users than normal packet switching networks.
ATM and ISDN-B combination allows high-speed interconnection of world's network.
Although the OSI reference model is universally recognized, the historical and technical open standard of the Internet is Transmission Control Protocol / Internet Protocol (TCP/IP).
The TCP/IP reference model and the TCP/IP protocol stack make data communication possible between any two computers, anywhere in the world, at nearly the speed of light.
Carrier-sense multiple access with collision detection (CSMA/CD) is a media access control method used most notably in early Ethernet technology for local area networking.Carrier-sense multiple access with collision detection is a media access control method used most notably in early Ethernet technology for local area networking. It uses carrier-sensing to defer transmissions until no other stations are transmitting.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

1. Asynchronous Transfer Mode (ATM) By- Agreeta Sharma A1000810010 AMITY INSTITUTE OF INFORMATION TECHNOLOGY
2. Asynchronous Transfer Mode (ATM) is a switching technique for telecommunication networks. It uses asynchronous time-division multiplexing , [1] [2] and it encodes data into small, fixed-sized cells . ATM differs from networks such as the Internet or Ethernet LANs that use variable sized packets or frames . ATM provides data link layer services that run over OSI Layer 1 physical links. ATM has functional similarity with both circuit switched networking and small packet switched networking. This makes it a good choice for a network that must handle both traditional high-speed data traffic (e.g., file transfers), and real-time , low-latency content such as voice and video . Asynchronous Transfer Mode
3.
4. Asynchronous Transfer Mode is a set of protocols used for computer networks . It is mostly used for Wide Area Networks . It splits the data, and encodes it into packets of a fixed size. Each packet can be routed differently, along virtual paths set up in the network. ATM has been very successful in WANs, as well as in LANs . Today, many ADSL implementations use ATM technology.

6. permanent virtual circuit , a virtual circuit that is permanently available. The only difference between a PVC and a switched virtual circuit (SVC) is that an SVC must be reestablished each time data is to be sent. Once the data has been sent, the SVC disappears. PVCs are more efficient for connections between hosts that communicate frequently switched virtual circuit , a temporary virtual circuit that is set up and used only as long as data is being transmitted. Once the communication between the two hosts is complete, the SVC disappears. In contrast, a permanent virtual circuit (PVC) remains available at all times.
9. ATM is more complex, but this complexity allows to give guarantees as to data rate , maximum delay, and jitter . These are usually called Quality of Service . Quality of Service or QoS is a method of providing better service for selected traffic types over various types of packet-switched networks.
