Remote Procedure Call in Distributed SystemPoojaBele1
Presentation to give description about the remote procedure call in distributed systems
Presentation covers some points on remote procedure call in distributed systems
Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers)..
Virtualization is a proved technology that makes it possible to run multiple operating system and applications on the same server at same time.
Virtualization is the process of creating a logical(virtual) version of a server operating system, a storage device, or network services.
The technology that work behind virtualization is known as a virtual machine monitor(VM), or virtual manager which separates compute environments from the actual physical infrastructure.
Universal mobile telecommunication System (UMTS) is actually the third generation mobile, which uses WCDMA. The Dream was that 2G and 2.5G systems are incompatible around the world.
-Worldwide devices need to have multiple technologies inside of them, i.e. tri-band phones, dual-mode phones
To develop a single standard that would be accepted around the world.
-One device should be able to work anywhere.
Increased data rate.
- Maximum 2048Kbps
UMTS is developed by 3GPP (3 Generation Partnership Project) a joint venture of several organization
3G UMTS is a third-generation (3G): broadband, packet-based transmission of text, digitized voice, video, multimedia at data rates up to 2 Mbps
Also referred to as wideband code division multiple access(WCDMA)
Allows many more applications to be introduce to a worldwide
Also provide new services like alternative billing methods or calling plans.
The higher bandwidth also enables video conferencing or IPTV.
Once UMTS is fully available, computer and phone users can be constantly attached to the Internet wherever they travel and, as they roam, will have the same set of capabilities.
Difference between OSI Layer & TCP/IP LayerNetwax Lab
Difference between OSI Layer & TCP/IP Layer
TCP/IP OSI
It has 4 layers. It has 7 layers.
TCP/IP Protocols are considered to be standards
around which the internet has developed.
OSI Model however is a "generic, protocolindependent standard."
Follows Vertical Approach Follows Horizontal Approach
In TCP/IP Model, Transport Layer does not
Guarantees delivery of packets.
In OSI Model, Transport Layer Guarantees
delivery of packets.
Learn what the Open Systems Interconnection (OSI) reference model is and how its seven layers of functions provide vendors and developers with a common language for discussing how messages should be transmitted between any two points in a telecommunication network.
: Instead of serving as protocol, the OSI model has become a teaching tool that shows how different tasks within a network should be handled in order to promote error-free data transmission.
An Introduction to the OSI ModelSource: Flickr/jonjohnson
The open system interconnection model, better known as the OSI model, is a network map that was originally developed as a universal standard for creating networks. But instead of serving as a model with agreed-upon protocols that would be used worldwide, the OSI model has become a teaching tool that shows how different tasks within a network should be handled in order to promote error-free data transmission.
These jobs are split into seven layers, each of which depends on the function’s “handed-off” from other layers. As a result, the OSI model also provides a guide for troubleshooting network problems by tracking them down to a specific layer. Here we’ll take a look at the layers of the OSI model and what functions they perform within a network.
MQTT - MQ Telemetry Transport for Message QueueingPeter R. Egli
Description of message queueing (MQ) protocol for the transport of telemetry data (MQTT - MQ Telemetry Transport).
MQTT is a protocol designed to fit the needs of Internet of Things scenarios. It is lightweight and efficient, but still affords all the features required for reliable messaging between wireless sensor / actor nodes and applications. MQTT decouples producer and consumer of data (sensors, actors and applications) through message brokers with publish / subscribe message queues called topics. MQTT supports different levels of quality of service thus providing the flexibility to adapt to the different needs of applications.
Further features like will and retain messages make MQTT well suited for sensor network scenarios as well as for lightweight enterprise messaging applications.
Open source implementations like Eclipse paho provide ample code for integrating MQTT in your own applications.

Even though the U.S. Department of Defense budget is shrinking and the country's military footprint worldwide is receding the need for the warfighter to have accurate and actionable intelligence has never been more critical. Data from Intelligence, Surveillance, and Reconnaissance (C4ISR) systems such as radar, image processing payloads on Unmanned Aerial Vehicles, and more will be used and fused together to provide commanders with real-time situational awareness. Each system will also need to embrace open architectures and the latest commercial standards to meet the DoD's performance, size, and cost requirements. This e-cast will discuss how embedded defense suppliers are meeting these challenges.

Docker now provides several building blocks, combining engine, clustering, and componentization, while the new networking and service features enable many new usecases such as multi-tenancy. In this session, you will first discover the new experimental networking and service features expected soon, and then drift rapidly to software architecture, explaining how a complete Docker stack unleashes microservices paradigms.
The first part of the talk will introduce what SDNs and service registries are to the audience and will cover corresponding network & service experimental features of docker accordingly, with a technical focus. For instance, it explains how to create an overlay network of top of a swarm cluster or how to publish services.
The second part of the talk moves from infrastructure to application concerns, explaining that application architecture paradigms are shifting. In particular, we discuss the growing porosity of companies’s IS (especially due to massive use of cloud services) drifting security boundaries from the global IS perimeter, to the application shape. We also remind that traditional SOA patterns leveraging on buses (ie. ESBs & ETLs) are being replaced by microservices promoting more direct, full-mesh, interactions. To get the picture really complete, we’ll also rapidely remind other trends and shifts which are already covered by other docker components: scalability & resiliency to be supported by the apps themselves, fine-grained applications, or even infrastructure commoditization…
Most of all, the last part depicts a concrete, state-of-the-art application, applying all the properties discussed previously, and leveraging on a multi-tenant docker full stack using new networking and services features, in addition to traditional swarm, compose, and engine components. And just because we say it doesn’t mean it’s true, we’ll be happy to demonstrate this live !
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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.
