TITLE: Multi-Dimensional Challenges in Open & Agile Software Ecosystem

ABSTRACT: The emerging technology is changing communication network and system in an unprecedented pace and drive the new ecosystem with the following characteristics: open, agile, software defined, virtual, data powered, highly distributed (module powered by API and microservices), highly automated, and highly secure.  This disruptive model presents both enormous opportunities as well as challenges.  The opportunity offers better ETE service reliability than each components while challenges the researchers and engineers of reliability with multi-dimensional risks such as software resiliency over the design and architecture of such an ecosystem.  A typical well-defined and self-confined device reliability challenge now becomes a challenge for both individual software components as well as the overall open and distributed software service chain.  The reliability model extends from device to an ETE service view, multi-layer, and multi-disciplinary model where architecture design, quality and change management in an agile development/deployment mode, real time fault and performance management automation powered by new generation of data analytics, service controls, highly automated flow orchestration, fraud detection, cyber-attack prevention in an open environment, all fully integrated to provide the desired reliability.  The briefing will also attempt to highlight two specific areas, microservices and Linux Foundation’s ONAP project, and the implications to reliability challenges.

TITLE:  Why We Have to Embrace Complexity for Reliability, Availability and Serviceability of Future Networks and 5G

ABSTRACT:  The decoupling of software architectures from hardware infrastructure (SDN) and the virtualization of resources and functions (NFV) are opening several new and intertwined challenges for future networks: one of them is “Complexity”, a systemic challenge. In fact, future 5G infrastructures will assume the form of extended and distributed execution and communication environments—from fog resources (up to the smart things and terminals) to edge- (e.g., network points of presence and small/medium-sized data centers), to cloud computing (e.g., big data centers) and across a transparent and pervasive fixed-radio connectivity. On top of the 5G infrastructures will reverberate a boom of network, cloud services and user applications, enabling a scenario of Everything -as-a-service, where everything will be an instrument to provide and consume ICT services and data. So, Future Networks and 5G will be like Complex Systems of Systems. It is a commonplace conclusion in sciences today that higher order phenomena cannot be directly derived from lower order systems: emerging properties and dominant characteristics in complex systems come from the interactions between its entities, rather than from the properties of a single entity in isolation. In the talk, it is argued that Complexity management should be embraced for meeting the requirements of Reliability, Availability and Serviceability of Future Networks and 5G.

TITLE:  AI Techniques for Reliability and Performance in Softwarized Networks

ABSTRACT: The emerging Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) paradigms are accelerating the transformation of proprietary and static traditional networks towards open and programmable networks composed dynamically.  SDN builds programmable networks through abstractions, open APIs (northbound and southbound) and the separation of control and data planes.  NFV targets the virtualization of network functions and aims at reducing vendor lock-in and bringing agility in the services and resources lifecycle operation and management.  This evolution and new requirements call for efficient SLA enforcement and management.  Guaranteeing SLAs and developing means to detect SLA and SLO violations in monitored virtualized network functions become major concerns for networks and services providers.  SLA management for the combined and joint use of SDN, NFV and clouds has hardly been addressed so far.  New approaches are needed to meet changing SLA and SLO management procedures.  Recently AI approaches have been revisited to address network performance issues, due to huge progress in such techniques.  The goal and proposed approach consist in computing and processing in real time the Key Performance Indicators (KPIs) and SLOs to drive predictive models capable of learning and pointing out possible SLO breaches.  The talk will present two different neural networks solutions that can be used for addressing SLA management.  Other challenges like anomaly detection may also be addressed using these techniques and will be mentioned in the context of a European collaborative project (CogNet) aiming at developing a common Cognitive Engine.  This engine is developed so as to accommodate using a single architecture various methods to address different challenges and use cases.

TITLE: Handling of uncertainty for reliable Information-driven Networks

ABSTRACT: The design of reliable engineered systems requires considering the uncertainty due to the lack of knowledge (epistemic uncertainty) or probabilistic variability (aleatory uncertainty).  Uncertainty, in e.g., the spatio-temporal properties of demands, the topology dynamics, has become the central notion to capture for the optimal solving of reliable network design, location, allocation, scheduling and routing problems as well as their combinations.  For instance, the model used for the joint server/cache placement, demand and flow assignment in information-driven networks removes the demand allocation independence property of due to strongly interrelated placement and assignment decisions.  Hence, preserving information accessibility, and more generally continuity of correct service, requires to capture demand uncertainty as part of the model.  For this purpose, optimization under uncertainty has been approached by math.programming paradigms that differ mainly in the definition and representation of uncertainty, e.g., known probability distributions, uncertainty sets.  The concept of strict robust optimization (RO) seeks at minimizing the worst-case cost under all possible uncertainty realizations.  Set-induced RO constructs solutions that are deterministically immune against any realization of the parameters/model data uncertainty in some compact sets.  Less conservative set-induced RO methods rely on the assumption that it is unlikely that all uncertain parameters reach simultaneously their worst-case value by limiting the cardinality of the uncertainty sets or by budgeting the total deviation from their nominal value.  In set-induced RO, all variables represent “here and now” decisions; they must be determined before the realization of the uncertain parameters becomes known.  In contrast, Adjustable RO (ARO) enables to choose a subset of variables (referred to as adjustable) after the realization of the uncertain data while the subset of nonadjustable variables must be determined before its realization.  The former variables represent “wait and see” decisions that can be made when revealing part of the uncertain data and that can adjust to the corresponding part of the data.  ARO yields solutions that are less conservative though computationally harder to produce than their nonadjustable robust counterpart.  Nevertheless, set-induced RO methods ignore all distributional information and are unable to evaluate expectations including probability measure; they also require domain knowledge for the specification of uncertainty sets. Instead, Distributionally Robust Optimization (DRO) represents model data as random variables over a family of probability distributions characterized by its descriptive statistics that can be derived from the data.  DRO aims at minimizing a worst-case probability functional, e.g., the worst-case expectation, where the worst case is taken with respect to an ambiguity set defined as a family of distributions consistent with the given prior information on the uncertainty.  The main advantage of this data-driven method is that it produces -by means of tractable approximations- solutions that are robust to distributional assumptions, less conservative than their (A)RO counterpart while enabling to compute bounds on expectations.  The motivation of using this technique for the solving of reliable design, location, allocation, scheduling and routing problems which sit at the core of information-driven networks/dependable information systems stems from the ambiguity in characterizing the probability distribution of demands in space (origin) and size which drives related decisions.  For instance, a data-driven DRO model which produces decisions that are robust with respect to the ambiguity set of all demand distributions -fulfilling prescribed statistical hypothesis tests- yields a computationally attractive approach for addressing demand uncertainty.

TITLE:  Improved Reliability for NFVI

ABSTRACT:  Especially with stateful telecom virtual network functions (VNFs), OpenStack “out of the box” does not meet reliability requirements for those applications running in a Cloud. Improvements to detection and triggering actions for infrastructure faults combined the recovery mechanisms for applications running in a Cloud have provided the service reliability needed.  In Ericsson, “Continuous Monitoring – High Availability (CM-HA) uses a ‘recreation’ automatic recovery action to ensure that the configured VM availability level is met.  Collaborating in OPNFV Project Doctor, Ericsson along with various groups are aligning on a solution to upstream to OpenStack. This presentation will cover additions to work with OpenStack components to deliver high availability for VNFs as well as the summary of the current work in OPNFV.

TITLE: Flexible softwarized networks: A RAS Perspective

ABSTRACT: Software Defined Networks (SDN), Network Function Virtualization (NFV) and Service Function Chaining (SFC) are part of the current evolution taking place in communication networks. These technologies promise several improvements such as shorter time-to-market, automatic scaling / elastic network services, etc.  The purpose of this presentation is to touch upon different aspects impacting not only availability but also reliability and serviceability.  In a first part of this presentation we look to the current / past situation and how the context is changing towards one subject to emerging services.  In the second part SDN, NFV and SFC are briefly introduced and the benefits highlighted.  The third part touches upon different aspects of SDN/NFV/SFC impacting RAS mainly from a technical point of view. This includes how to implement protection in a NFV/SFC context (availability improvement) up to performance profiling in order to meet SLAs (reliability rather than availability perspective).  The last part will touch upon DevOps and its relation to RAS: in contrast to the third part, DevOps requires a cultural change in order to have the potential to become a success.  The automation in the DevOps process will impact the servicability significantly
