The document provides an introduction to networking and local area networks (LANs). It discusses network fundamentals including different types of networks such as WANs, MANs, LANs and PANs. It also covers common LAN topologies like star, ring, bus and mesh. The document then describes various LAN hardware components including cables, connectors, repeaters, hubs, bridges, switches and routers.
A network consists of two or more computers that are linked together in order to share
the resources, such as printers, exchange files among computers, with the help of electronic
communications. The computers on a network may be linked by cables, telephone lines,
radio waves, satellites, or infrared light beams etc.
EFFICIENT REAL-TIME VIDEO TRANSMISSION IN WIRELESS MESH NETWORK IJORCS
We are experiencing rapid improvement in video transmission and picture quality. The technologies are supporting us with real-time video transmissions such as video conferences and webinars. Soon reliable, simple, low cost real-time video will become essential, providing its extensive support to mobiles; PDA’s etc. These enhancements are going to affect the consumer behaviour, business culture. Video transmission includes transmitting packets through Wireless Mesh Network (WMN), which turned out to be a challenging scenario for real-time video services. Due to the existing nature of wireless networks include the presence of unpredictable delays and high packet error rates due to the error-prone nature of the wireless links. In this paper, we will propose a model which provides high capacity data transfer with reduced delay. We have simulated and achieved results with higher throughput.
UMTS Long Term Evolution (LTE) has emerged as the favored next step on the road for both 3GPP-based networks and for operators using a variety of cellular standards around the world. Among its many attractions are improved capacity, reduced latency, easier integration with packet-based networks that use internet protocol (IP), and lower cost-per-bit.
We conclude that LTE will benefit from the use of femtocells from the outset.

MOBILE IP ON MOBILE AD HOC NETWORKS: AN IMPLEMENTATION AND PERFORMANCE EVALUA...acijjournal
Mobile computing devices equipped with transceivers form Mobile Ad Hoc Networks (MANET), when two
or more of these devices find themselves within transmission range. MANETs are stand-alone (no existing
infrastructure needed), autonomous networks that utilise multi-hop communication to reach nodes out of
transmitter range. Unlike infrastructure networks e.g. the Internet with fixed topology, MANETs are
dynamic. Despite the heterogeneous nature of these two networks, integrating MANETs with the Internet
extends the network coverage area of the Internet, and adds to the application domain of MANETs. One of
the many ways of combining MANETs with the Internet, is the use of Mobile Internet Protocol (Mobile IP)
alongside a MANET routing protocol, to route packets between the Internet and the MANET, via Gateway
agents. In this paper, we evaluate the performance of Mobile IP on MANET in Network Simulator 2 (NS2).
We have implemented Mobile IP on Ad hoc On-demand Distance Vector (AODV), Ad hoc On-demand
Multiple Distance Vector (AOMDV) and Destination-Sequenced Distance Vector (DSDV) routing
protocols, and compared performances based on Throughput, End-to-End Delay (E2ED), Packet Delivery
Ratio (PDR) and Normalized Packet Ratio (NPR). The simulation results suggest that, on-demand routing
within the MANET better serves Mobile IP on MANETs.

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.
