Agenda Details: "Use Cases (5G/Edge Computing)" - Dilip Krishnaswamy (Reliance Jio, India) Abstract: Emerging 5G network architecture will consist of a large number of distributed "clouds" with dynamically varying resource availability in terms of compute, or storage, or network bandwidth, or energy, and with support for edge computing/services. The ability to serve users with dynamic requirements across geographies using such distributed resources will require learning and prediction of distributed models across users and infrastructure to dynamically and efficiently allocate resources. This talk will cover different use-cases that drive the need for such distributed architecture, and motivate the need for building distributed models of users and infrastructure, and the need for dynamic resource optimization across these distributed and edge clouds. "Architecture and Benefits" - Sastry Isukapalli (AT&T, New Jersey, USA) Abstract: This talk focuses on the Open Network Automation Platform (ONAP) Optimization Framework (OOF) open source effort, which is a declarative framework based on a Policy- and Model-driven, architecture with AI assists. While the core design framework is based on MiniZinc, it also supports optimization applications based on generic or problem-specific custom solvers. The system is presented with a set of example applications, including dynamic resource allocation under various complex constraints. "Recent Trends in Constraint Optimization and Satisfaction" - Nina Narodytska (VMware, California, USA) Abstract: In this talk we overview several constraint optimization solvers and consider the main design principles behind these search procedures. First, we look at Boolean Satisfiability (SAT) and Integer Linear Programing( ILP) solvers and their extensions. These decision procedures offer a restrictive modeling language based on Boolean logic and integer linear constrains, and powerful search procedures. Next we will talk about Constraint Programing (CP) solvers, whose rich modeling languages include expressive global constraints and a variety of decision search procedures, e.g., backtracking search, lazy-clause generation, etc. "Software-defined Constrained Optimal Routing (SCOR)" - Siamak Layeghy (Univ. of Queensland, Australia) Abstract: Software-defined Constrained Optimal Routing (SCOR) is a SDN northbound interface which is based on constraint programming techniques to provide a robust, declarative interface for stating networking problems. The main advantage of SCOR, is to hiding the complexity of solving the problem from the user. Accordingly, users only state the constraints and utility functions of the routing problem and the solution is provided by a powerful generic solver. It is implemented in the MiniZinc constraint modelling language consisting of nine fundamental constraint programming predicates which cover different aspects of the routing problems. This interface (set of predicates) is sufficiently expressive to handle all the known and relevant QoS routing problems. Furthermore, the practicality and scalability of the approach are demonstrated via some example scenarios, with use cases in real-world SDN controllers.
