Topic: Reliability Challenges for Emerging Technologies Based Networks - A Long Road to Standardization


There is a growing concern from the telecom community about the reliability of Emerging Technologies based (IP-based) telecommunications networks, including the services provided under failure condition. This presentation will give a quick historic perspective of the standardization efforts regarding the reliability of telecom networks from the conceptual perspective (from component to system to network level). Then, it will discuss the reliability issues for the Emerging Technologies (e.g., SDN, NFV, Cloud Computing, etc.) based networks and the industry’s challenge to maintain the momentum on by avoiding a protracted Reliability Standards’ effort.

Topic: Reliability Challenges in the Wireless/Mobility Networks


The following areas will be covered

Dr. Ying Chin (Bob) Yeh, IEEE Fellow; Technical Fellow, Boeing Commercial Airplanes

Ying Chin (Bob) Yeh joined Boeing Commercial Airplanes  in 1981, and has been on Boeing Fly-By-Wire (FBW) computers development programs (FFM, 7J7, 777, 7E7, 787, 777X) since 1984, more specifically computer architectures and redundancy management scheme to achieve/certify safety critical electronics systems with E-10 per hour functional integrity and availability.

He received his Ph.D. from University of Ottawa in 1973; M.S. from National Taiwan University, Taiwan, in 1970; B.S. from National Cheng Kung University, Taiwan, in 1967, all in Electrical Engineering.

Bob is an IEEE Fellow for contributions to ultra-reliable real-time embedded system, and a member of IFIP (international federation for information processing) Working Group 10.4: Dependability and Fault Tolerance.

Topic: Ultra-Reliable Fly-By-Wire Computers for Commercial Airplanes’ Flight Controls Systems


This presentation begins with the fundamental concept of dependability developed by the dependability and fault-tolerance technical community. It is followed by the 777 FBW design philosophy for safety covering the common mode failure/single point failure, and the dissimilarity.

The command/monitoring concept for the self-monitoring computing channel of 777 Primary Flight Computer (PFC) is elaborated. The closed loop (monitoring) concept of 777 Actuation Control Electronics (ACE) is depicted. It is concluded by the concept and feature for fail-passiveness of the 777 PFC-ACE data paths.

With building blocks of fail-passive electronics, extremely high functional integrity and availability systems can be configured via hardware redundancy.

Professor Chunming Qiao, IEEE Fellow, the State University of New York (SUNY) at Buffalo

Topic: Challenges and Opportunities in Improving Cloud Service Reliability and Availability


Cloud services may be disrupted by various failures ranging from very frequent small scale failures (such as a few isolated individual server/switch failures) to less frequent, yet non-negligible, large-scale failures (such as rack or cluster failures). With our growing dependence on cloud services for both commercial and personal use, their reliability and availability have become increasingly critical. Despite existing (mostly ad hoc) approaches to improving the cloud service reliability and availability, a recent report found that on average, a service outage lasts about 134 minutes, and these service outages cost about $426 billion of loss worldwide annually. In addition, existing SLAs are often loosely defined, and lack of reliability/availability guarantees has been cited as the top concern over cloud services among IT professionals in a 2012 global survey. In this talk, I will discuss both the challenges and opportunities related to service availability prediction, resource provisioning, and SLA contract design from the perspective of cloud service providers, and present our work on cost-effective solutions to problems ranging from creating survivable virtual infrastructures in a distributed multi-datacenter environment, to availability-aware VM placement/allocation.

 Dr. Michael Tortorella, Research Professor, Rutgers, the State University of New Jersey

Dr. Tortorella is a leading communications industry expert in reliability management, engineering, modeling, and life data analysis.  Over a 26-year career at Bell Laboratories he was responsible for research and implementations in fundamental system, network, and service reliability engineering methodologies as well as for management of reliability in such critical projects as the SL-280 undersea cable system, the world's first application of fiber-optic technology in an intercontinental, undersea system.  He played a major role in many AT&T and Lucent product reliability studies, culminating in the creation of CADRE, a reliability modeling system for circuit packs that encompasses circuit simulation, thermal analysis, and uncertainty modeling in a single package that is fully integrated with computer-aided design systems used for circuit pack creation.

Formerly a Distinguished Member of Technical Staff in the Design for Reliability Processes and Technologies Group in Bell Laboratories, Dr. Tortorella is now Managing Director of Assured Networks, LLC, a consultancy focused on network and service reliability and performance improvement.  He is concurrently a research professor of industrial and systems engineering at Rutgers University and an adjunct professor at Stevens Institute of Technology.  In addition to teaching courses in industrial engineering, operations research, and statistics, he maintains a robust research program that has direct impact on the concerns of the CQR.  This program includes investigations into how stochastic flows in an IP network determine the performance and reliability of services carried on those networks, modeling frameworks for control of IP networks under stressed conditions, and foundational issues in queueing theory.  Additional current research interests include stochastic flows, network performance, management, and control, stochastic processes and their applications to reliability, life data analysis, and next-generation networks, as well as design for reliability methods and technologies.  Dr. Tortorella has published extensively in these areas.  At Bell Labs, his responsibilities included systems and reliability engineering for next-generation networks.  He is Advisory Editor for Quality Technology and Quantitative Management, where he has worked to increase the number of publications pertaining to the communications industry.  He was formerly Area Editor for Reliability Modeling and Optimization for the IIE Transactions on Reliability and Quality Engineering and was Guest Editor of a recent issue on Reliability Economics.  He also served an Associate Editor of Naval Research Logistics and was Guest Editor for a recent issue on Computations in Networks.

Dr. Tortorella received his Ph. D. in mathematics from Purdue University.

Topic: Demystifying Reliability Engineering and Management for Cloud Services


Cloud services, including computing, data backup, file sharing, etc., are a major source of revenue for telecom providers.  They are often advertised as higher-reliability, safer, and more-secure alternatives to local storage and computing.  Service providers need to understand how their customers perceive the reliability of these services so that they can back up their claims and sensibly offer SLAs.  This presentation offers a practical perspective on how reliability of cloud services can be evaluated and managed through straightforward quantitative models.  We also point out some challenging problems that remain.
