"Automatisierung im DWH" war das Thema unserer Experten Marian Strüby und Dr. Jens Bleiholder zusammen mit Ulf Jeffke, Manager Voice & Data Anlalyst - Vodafone Kabel Deutschland, bei der DOAG 2015 Konferenz und Ausstellung.
Modularisierung, Standardisierung, Automatisierung. Mit diesen drei Stichworten kann man die Vorteile des ODI 12c als ETL-Tool im eigenen DWH-Projekt auf den Punkt bringen. Der ODI eröffnet hier eine ganze Reihe an Möglichkeiten, die Entwicklung eines DWH zu beschleunigen, dem Entwickler Arbeit abzunehmen und gleichzeitig die Entwicklung zuverlässiger und fehlerfreier zu machen. Dabei wird die Entwicklung noch wesentlich effizienter, wenn man auch bei Datenmodellierung und Architektur auf Modularisierung, Standardisierung und Automatisierung achtet und z.B. Data Vault verwendet. Anhand von Beispielen aus einem Kundenprojekt stellen wir unsere Erfahrungen auf diesem Gebiet vor und zeigen, wie der ODI 12c im Projekt dabei hilft und ein DWH größtmöglich automatisiert, aufzubauen: Generieren von Datenmodellen und zugehörigen Mappings, automatisches Deployment, Anpassung von Knowledge-Modulen etc. Den Kunden freut es, bekommt er nun mehr DWH für sein Geld. Den Entwickler freut es, muss er nun nicht mehr die langweiligen immer gleichen Arbeiten erledigen. Den Endanwender freut es, bleibt nun mehr Zeit übrig, um auf seine Probleme und Businesslogik einzugehen.

Ethernet technology has emerged as a cost-effective, mature, robust, high-speed, and versatile choice for MAN/WAN networking of critical defense establishments and military installations – for e.g., army, navy, and air force bases, mission commands, remote war centers, the Pentagon, and other security agencies. Intelligent Ethernet helps to achieve IP-centric service requirements, while enabling wireless and fixed-line networks to evolve to a fast, economical, packet-switched infrastructure. The last few years have seen tremendous advancements in Ethernet architecture, its features, switch/router system design, and its integration with optical technologies. This tutorial provides a clear conceptual overview of optical Ethernet technology advances, network architectures, and benefits for military and defense network planners, network architects, and system engineers.
Packet-Optical Integration: The Key to Evolving Towards Packet Enabled Agile ...Vishal Sharma, Ph.D.
The operator's paradox, for the past several years now, has been that while there is an explosion in data traffic volumes to the tune of 45-65% yearly, the corresponding revenue growth is in the single digits at best. To bridge this gap between rising operating costs (spurred by increased network capacity demands) and relatively flat revenues, providers must assess how to better architect their...
A fundamental problem before carriers today is to optimize network cost
and performance by better resource allocation to traffic demands. This is especially
important with the packet infrastructure becoming a critical business resource.
The key to achieving this is traffic engineering (TE), the process of
systematically putting traffic where there is capacity, and backbone
capacity management, the process of ensuring that there is enough network
capacity to meet demand, even at peak times and under failure conditions,
without significant queue buildups.
In this talk, we first focus on the TE techniques and approaches used
in the networks of two large carriers: Global Crossing and
Sprint, which represent the two ends of the traffic engineering spectrum.
We do so by presenting a snapshot of their TE philosophy, deployment strategy,
and network design principles and operation.
We then present the results of an empirical study of backbone traffic
characteristics that suggests that Internet traffic is not self-similar at
timescales relevant to QoS. Our non-parametric approach requires minimal
assumptions (unlike much of the previous work), and allows
us to formulate a practical process for ensuring QoS using backbone
capacity management.

A New Analysis for Wavelength Translation in Regular WDM NetworksVishal Sharma, Ph.D.
We present a new analysis of wavelength translation in
regular, all-optical WDM networks, that is simple, computationally
inexpensive, and accurate for both low and high
network loads. In a network with
k
wavelengths per link,
we model the output link by an auxiliary
M/M/k/k
queueing
system. We then obtain a closed-form expression for
the probability
P succ
that a session arriving at a node at a
random time successfully establishes a connection from its
source node to its destination node. Unlike previous analyses,
which use the link independence blocking assumption,
we account for the dependence between the acquisition of
wavelengths on successive links of the session’s path. Based
on the success probability, we show that the throughput per
wavelength increases superlinearly (as expected) as we increase
the number of wavelengths per link; however, the
extent of this superlinear increase in throughput saturates
rather quickly. This suggests some interesting possibilities
for network provisioning in an all-optical network. We verify the accuracy of our analysis via simulations for the torus
and hypercube networks.

A Survey of Recent Advances in Network Planning/Traffic Engineering (TE) ToolsVishal Sharma, Ph.D.
Designing & managing operational IP networks is a complex, multi-dimensional
task. A fundamental problem before carriers today
is to optimize network performance by better resource allocation to traffic demands.
This requires a systematic evaluation of options, a thorough scenario analysis,
and foolproof verification of network designs, all of which are increasingly
possible only with help from automated TE and planning tools.
In the past few years, significant advances have been made in enhancing existing
tools and developing new ones that help providers rapidly identify potential
performance problems, experiment with solutions, and develop robust designs.
Several techniques from optimization theory, linear programming, and
models of effective bandwidth calculation have been incorporated in such
tools, as have detailed models of several vendor systems.
We present a comparative analysis and an overview of key features of some key
commercially available network planning/TE tools, and outline how
they could be leveraged by carrier network engineering/planning
organizations to perform detailed network analysis, proactive/reactive
TE, and network design.
We first give an overview of the architecture, design philosophy, and canonical
features of modern design tools, and then focus on new enhancements to some
popular tools
as well as key distinguishing features of some newly developed ones.
In particular, we focus on decision support tools for IP network planning
and network analysis, including the latest versions from
WANDL, OPNET, Cariden..
We also present a perspective on current outstanding carrier requirements
for TE/planning tools that was synthesized by our conversations with
several leading Tier 1 and Tier 2 carriers.
With the rapid growth of IP networks in South-Asia in the past
few years, and the advent of new services and applications -- be they
wireless/wireline broadband Internet access, cable telephony, VoIP, remote
teleconferencing, e-governance, or mobile entertainment -- a key
issue before carriers is how to design and operate their networks as
methodically and as efficiently as possible to maximize both customer
retention and profits.
While several best practices typically emerge from each provider\'s
unique situation and cumulative experience (the "art" of network design), there
are certain operational precepts that systematize and streamline the
complex, multi-dimensional task of designing and managing modern, operational
IP networks (the "science" of network design).
In this talk, we first discuss the overall network design process and the
manner in which control over the network must be exercised at varying
timescales to achieve efficient operation. Next we discuss the
functions that the operational, engineering, and planning teams at a
carrier must typically execute, their inter-relationships, and
the importance/rationale for performing them to optimize network
performance.
We then outline some network design best practices that have evolved
over the past decade, drawing upon examples of carriers such as
Sprint, Global Crossing, AT&T, NTT, and Reliance. We conclude with
a look at some automated traffic engineering and planning tools,
and how they enable carriers to rapidly identify potential
performance problems, rigorously experiment with/evaluate design
options, perform thorough scenario and network analysis, and
develop robust designs.
Multi-Protocol Label Switching has become by far one of the most important Internet technologies of the last 15 years. From humble beginnings back in 1996-97, it is literally the defacto standard in a large majority of service provider networks today. This presentation, delivered to executives at MTNL, Mumbai (a large regional carrier in India), explains the key operational principles behind MPLS, and its significant applications.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

My goal is simply to recap some salient points that we’d want to keep at the back of our minds during the course. I’ll then highlight some fundamental switching notions. These are important because we’ll see that a lot of the effort in the design of architectures and algorithms for switch/routers is directed at addressing these basic notions. Finally, I’ll look at the basic architectural components of a packet router and a circuit switch or TDM cross-connect

My goal is simply to recap some salient points that we’d want to keep at the back of our minds during the course. I’ll then highlight some fundamental switching notions. These are important because we’ll see that a lot of the effort in the design of architectures and algorithms for switch/routers is directed at addressing these basic notions.

Get up to 1TB of data per day per POP! Timestamp have 2us accuracy, header has 44 bytes.
Where does traffic come from or which sources/links/customers contribute to traffic and how much? POPs: What is the variaton of traffic per time of day? What is the distribution of traffic across aggregate flows? That is, what information on routing and traffic flow between POPs. Obtain information for traffic in both time and space. Matrix design: Is there a better way to spread the traffic across the paths between POPs? At what granularity should this be done. We look at this in the techniques lecture.
Transmit time through a router is critical, since it is Critical for delay-sensitive application Adds to e2e delay Is useful to control QoS
Observations: This histogram shows that the most common assumption that traffic from a source is uniformly distributed to all destinations does not match Internet behavior at all! This is because: Some POPs sink larger traffic than others – based simply on geography, based on where international trunks terminate, etc. The traffic distribution between POPs exhibits a significant degree of variation – the vol. Of traffic that an egress POP receives depends on the number and type of customers attached to the egress POP. Likewise, the amount of traffic an ingress POP generates depends on the no. and type of customers, access links, their speeds etc.
TE: If a new POP/link is added, can they predict where in the network they need to add new bandwidth? Conversely, where do they need an additional POP/link to tackle congestion or growing traffic demands? BGP peering: Are we carrying unwanted IP traffic? Are our peers’ announcements consistent with our BGP announcements? Intra-domain routing: verify load balancing? Design adaptive policies SLAs: Can use info. on how much traffic is exchanged between peers and how it varies to see what guarantees can be offered for delay, throughput, etc. Reports: Can use to generate reports for customers that verify that customer traffic is being correctly and consistently routed
I’ll now highlight a few switching phenomena that one must contend with in both circuit and packet switching. The reason for considering them here is that all architectures are ultimately designed to overcome these phenomena. The first of these is output contention, which occurs when the sources transmit at rates whose aggregate exceeds the capacity of one or more outputs. Circuit and packet switches handle output contention differently. In circuit switching of course no new circuit can be setup on a link that is full. So the moment there is output contention, one must reject any new circuit. In packet switching, the contention handling differs depending on the nature of the contention. For example, short-term congestion can be tackled by buffering data and transmitting it a short while later when resources become available. Long-term or sustained congestion can be handled in one of three ways: dropping excess data (the question here is whom to drop), by applying admission control at the source (the question here is whom to throttle), or by using flow control and sending feedback to the source (the question here is whom to reduce and by how much). The sizing of the buffers at various points in a switch/router is critically related to the nature and type of contention the switch is designed to handle.
