Topic: A Scalable Networking Architecture for Improving Performability Within and Across Data Centers
As data centers are scaling in size and across multiple geographic locations, some goals include improving performance, high availability, data locality, and disaster recovery. A scalable networking architecture is proposed with a hybrid combination of the Spline/Leaf architecture with optical switching (OCS) to provide dynamic low-latency communication. Advancements in OCS technology combined with the control plane of Software Defined Networking (SDN) technology provides a more dynamic approach than has been available in the past. Stochastic models are starting to be explored as an evaluation method with initial interest in the composite Performability metric.

Topic: The Service Reliability Ecosystem
Telecommunications services have developed widely and rapidly away from the simple, ubiquitous POTS of decades past. The current environment is characterized by a vast diversity of new services, many service providers, and compelling trends in new infrastructures for service delivery. We aim to provide clarity for service users and service providers in the vital area of service reliability so that the telecommunications industry may effectively and profitably deliver services meeting service customer requirements for reliability. Our key points are that (1) service reliability is different from product reliability, (2) it is necessary to abstract the requirements for service reliability from the reliability requirements for the service delivery infrastructure (SDI) and its elements, and (3) the SDI network reliability requirements must arranged so that the end-user (service purchaser) service reliability requirements will be met.

Topic: Operations Aspects of Reliability: Measurements and Network Management - Applying Legacy Principles to New & Emerging Technology
This discussion will focus on Network Management Principles and data collection which have been utilized by the TDM Switching Network Management community for decades. Examples of Network data measurements and standards for providing this data in vendor generic Operations Support Systems (OSS) will be discussed, along with a comparison to emerging technologies traffic flow. Although new technology offers a significant shift from the architecture of existing TDM networks, the Principles of Network Management and existing data measurements should still be the driving factor to jumpstart Network Management capabilities for protecting the Network and ensuring the best possible traffic completions.
