Topic: Telco-grade Availability from an IT-grade Cloud
Abstract
No current cloud solutions promise better than 99.95% availability, but network operators deploying virtualized network functions are, quite reasonably, unwilling to relax their traditional requirement that services they deliver from their virtualized network should achieve five-nines availability. In this session, Martin Taylor explores the different dimensions of network service availability requirements and explains how those requirements can be met using IT-grade cloud technology with the right approach to VNF design, cloud design, deployment practice and orchestration.

Topic: Leveraging the New change to meet with the Carrier Grade Requirements of NFV
Abstract
NFV introduced new technologies into telecom industry, such as COTS, Virtualization, decoupling, etc. these new changes will bring big challenges for network and service reliability while bring dramatic benefit for industry.

Topic: Performance and Resiliency Considerations while scaling Virtualized Network Functions
Abstract:
Performance and resiliency have been cornerstone requirements for carrier grade network functions. SDN controlled cloud platform architectural principles of open source use, homogeneity, reusability and optimal asset utilization complement the traditional carrier grade network principles. To comply with all these objectives, VNF software design needs to take into consideration several new criteria. This criteria includes deterministic workload categorization, disaggregation or microservice support in VNFs, VNF software efficiency estimation and measurability. This talk will cover some of the foundational steps in scaling VNFs for performance and resiliency.

Topic: Airbus Fly-By-Wire Computers: A320-A350
Abstract
Airbus develops the first commercial airplane fly-by-wire (FBW) computers in the 1980th with certification of A320 airplane in 1988. The Airbus FBW computers design philosophy can be stated below:
-
Active-Standby control of an actuator for a control surface with multiple actuators, other actuators in By-Pass Mode
-
Active-Passive control of an actuator among Flight Control Computer channels: upon detecting loss of an active computer channel commands, the passive computer will become active
-
Self Monitor computer channel, with Command Lane and Monitor Lane
The A320 FBW Computers are evolved to A330/A340, A380, and A350, with similar design philosophy, while with changes of microprocessors, compilers, programming languages, design tools, and data networks.
Readers can appreciate that with same certification requirements, there are much different between two competing FBW (Computers) Systems – Airbus vs Boeing.

Topics: New Reliability and Performance Challenges in Rearrangeable Networks
Abstract:
Telecom networks are no longer fixed structures. Software-defined networking (SDN) causes deliberate rearrangements in response to changing traffic or other network management demands. Failures and repairs cause changes in capacity of network elements (routers and transport links). Recognizing that packet delay and packet loss are the primary drivers of service reliability, it is necessary to understand how network rearrangements affect the flow of packets. This talk discusses new reliability and performance challenges posed by rearrangeability and introduces some ideas for quantitative modeling of flows in rearrangeable networks. We review flows in transportation networks as a simple introduction and move on to discuss briefly queueing network models and the Gale-Hoffman theorem in this context.

Topic:
Reliability Challenges of Cloud-based Networks Used for World-Class Events
(Study
Case:
The first-ever, cloud-based network used for the 2015 European Games in Baku,
Azerbaijan)
Abstract
There is a growing concern within the telecom community and especially the Organizing Committees of world-class events (e.g., Olympic Games, European/Asian/Pan-American Games, etc.) regarding the reliability of cloud-based telecommunications networks, including the services provided under failure conditions. This presentation will give a high-level description and the reliability challenges of the first-ever, cloud-based network used for the 2015 European Games in Baku, Azerbaijan. After all, it served as a "network experiment" to see if it is a viable network design for future world-class events.
