What is SS7? An Introduction to Signaling System 7Alan Percy
SS7 or Signaling System 7 is the dominant protocol used to control the public telephone network. Call routing, number portability, caller-ID, mobile SMS and more are handled using SS7 in the public network. SS7 (along with SIGTRAN for transport), allow application to access public network resources for call control and authentication. During this session, we share some background on SS7, show how it is used in everyday communications, and provide some use cases in popular applications.

10-Gb/S Transmission of Wdm Pon for Man with 50km Reach Based On FtthIJERA Editor
The wavelength-division-multiplexed passive optical network (WDM-PON) is considered to be the next evolutionary solution for a simplified and future-proofed access system that can accommodate exponential traffic growth and bandwidth-hungry new applications. WDM-PON mitigates the complicated time-sharing and power budget issues in time division- multiplexed PON (TDM-PON) by providing virtual point-to-point optical connectivity to multiple end users through a dedicated pair of wavelengths. The objective of this paper is proposed a scheme for metropolitan area networks comprising optical components based on arrayed waveguide grating multiplexers, demultiplexers .The Arrayed waveguide gratings based multiplexers and demultiplexers for WDM applications prove to be capable of precise multiplexing and demultiplexing of a large number of channels with relatively low losses.

This presentation is based on Evolution of Passive Optical Network. We study strategies for increasing the PON’s capacity regardless of its technology: EPON (Ethernet-based PON) or GPON (Gigabit capable PON). It can also introduce other future Technologies like SCM Hybrids and Coherent PONs.
Performance analysis of Multiband - OFDM systems using LDPC coder in pulsed -...IDES Editor
In this paper, a combined approach where low density
parity check (LDPC) codes are used to reduce the complexity
and power consumption of pulsed orthogonal frequencydivision
multiplexing (pulsed-OFDM) ultra-wideband (UWB)
systems is described. The proposed system uses LDPC codes
to achieve higher code rates without using convolution
encoding and puncturing thereby reducing the complexity and
power consumption of pulsed-OFDM system. The LDPCpulsed-
OFDM system achieves channel capacity with different
code rates and has good performance in different channel
fading scenarios. The pulsed OFDM system is used where
pulsed signals could spread the frequency spectrum of the
OFDM signal. The performance of LDPC-pulsed-OFDM
system for wireless personal area networks (WPAN) is
analyzed for different UWB indoor propagation channels (CM3
and CM4) provided by the IEEE 802.15.3a Standard activity
committee. To establish this, a design of LDPC-pulsed-OFDM
system using the digital video broadcasting-satellite-second
generation (DVB-S2) standard and provide the simulation
results for the different code rates supported by LDPC codes
is presented.
analysis on design and implementation of 4×10 gb s wdm tdm pon with disparate...INFOGAIN PUBLICATION
This article presents a design of wavelength division multiplexing/ Time division Multiplexing (WDM-TDM) in passive optical network with a data rate of 10 Gbps. The implementation has been carried out for varying link distance from 40km to 100km for 4 different wavelengths with a maximum of 32 supporting users with two different receiver photodiodes. The parameters such as BER and the Q-factor for PON network is being analyzed with the link distance. The BER is decreased as the distance of the network is increased when using the APD receivers than PIN receiver. Optimal value of BER is obtained for a distance of 97 Km in APD and 96 Km in pin receiver.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
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.

42
The NGN concept takes into consideration new realities in the
telecommunication industry characterized by factors such as the
need to converge and optimize the operating networks and the
extraordinary expansion of digital traffic
(i.e. increasing demand for new multimedia services, increasing
demand for mobility, etc.)
NGN also aims to tackle important concerns raised from the use of
current IP-based services:
(i.e. QoS and security) (c) Anuradha Udunuwara
43. Definition
43
NGN is a packet-based network able to provide
Telecommunication Services to users and able to make use of
multiple broadband, QoS-enabled transport technologies and in
which service-related functions are independent of the underlying
transport-related technologies. It enables unfettered access for
users to networks and to competing service providers and
services of their choice. It supports generalized mobility which will
allow consistent and ubiquitous provision of services to users.

44. Fundamental aspects
44
Packet-based transfer
Separation of control functions among bearer capabilities, call/session, and application/service
Decoupling of service provision from transport, and provision of open interfaces
Support for a wide range of services, applications and mechanisms based on service building blocks (including real
time/streaming/non-real time services and multi-media)
Broadband capabilities with end-to-end QoS and transparency
Interworking with legacy networks via open interfaces
Generalised mobility
Unfettered access by users to different service providers
A variety of identification schemes which can be resolved to IP addresses for the purposes of routing in IP networks
Unified service characteristics for the same service as perceived by the user
Converged services between Fixed and Mobile networks
Independence of service-related functions from underlying transport technologies
Support of multiple last mile technologies
