TITLE: Intelligent Resiliency for A Converged World

ABSTRACT: Network traffic is growing exponentially, driven by the insatiable hunger for data consumption and the introduction of new technologies like AR/VR, massive IoT and 5G.  Supporting this growth, as well as the tremendous architecture challenges posed by greater complexity, faster speeds and enhanced reliability necessitates a transition from a hardware-based network to an intelligent, flexible, software-defined network.  AT&T will share how we are using a DevOps approach to build a highly scalable, agile configuration validation and proactive change management de-confliction, as well as network cloud site traffic migration and recovery automation.

TITLE: Impact of Virtualization on Telecom Network Reliability

ABSTRACT: Virtualization of Network Functions has some profound impacts on reliability management, planning, testing, and analysis.  Along adaptation of 5G, telecom networks are used in some mission-critical applications, where ultra-reliability is requested.  At the same time, the change of focus from hardware to software has some impact on the methodologies that are applied in reliability analysis.  Therefore, it is important that reliability engineers adapt at least some basic understanding of software and software reliability.  Until now, the usual background for reliability engineers has quite often been on hardware.

Machine learning and artificial intelligence provide some new methods to run preventive maintenance procedures. However, it is important that subject matter experts are involved when these methodologies are implemented to telecom networks equipment and systems.

TITLE:  Establishing Customer Experience Aspects in Mobile Network Serviceability

ABSTRACT: During the past decades, the traditional Performance Management Process in mobile networks has been gradually transforming to a customer-centric one, promoting the visibility of the customer aspect for the Quality of Service (QoS) they are enjoying.  This has been driven by the fierce competition in the mobile communications market regarding price and quality. Superior customer experience is now considered as one of the most powerful leverages to reduce the churn and increase the Average Revenue Per User (ARPU).  The technological advances in the Big Data & Analytics technologies have been a key enabler that helped collect, process, and provide the relevant insights for the customer experience.  This process now involves many stakeholders such as Strategy, Customer Care, CRM, SQM, SoC, etc.  In this talk, we will focus on the key ingredients for enabling this transformation.

TITLE:  A holistic model driven approach for addressing safety and security early design challenges of complex critical infrastructures

ABSTRACT:  Security and reliability of complex critical infrastructures is very important for economic, environmental and social reasons throughout their lifecycle (design, operation, maintenance, decommission). The interdisciplinary and inter-system dependencies in these systems introduce difficulties in the identification of safety and security risks that emerge from emerging behavior. Late discovery of safety and security design weaknesses can lead to increased costs, additional system complexity and delays to the deployment of the system. 5G network technologies promise a new level and scope of networking, ranging from high speed connections to low power Internet of Things applications. With this high level of integration and connectivity, there is an increased need for methods and tools for early high level security and safety assessment. These assessments focus on concepts like resilience/survivability (e.g. defense in depth capabilities) and not on specific security or reliability/security technologies. It is assumed that regardless of the perceived level of security measures in place, a determined (motivated, capable and/or well-funded) attacker can find ways to penetrate a layer of defense and then the defense goal is transformed to how fast the attack can be detected, isolated, mitigated and tracked. In a similar way, regardless of a low calculated failure probability of a device based on known failure modes, there is always a risk that remains and unexpected interdisciplinary interactions can also contribute to this risk. This presentation will focus on a model-driven approach for early safety and security assessment of complex critical infrastructures.
