Project Description


The overarching goal of this proposal is to enable National Labs and Universities to request and provision end-to-end intelligent network services for their application workflows leveraging SDN capabilities. Our approach is to design network abstractions and an operating framework to allow host, LAN, and WAN auto-configurations based on infrastructure policy constraints designed to meet end-to-end service requirements. We propose a comprehensive approach that combines deployment of SDN infrastructure across multiple labs/campuses and WAN with a focus on usability, performance and resilience through: a) policy-guided end-to-end orchestration of resources; b) auto-provisioning of network devices and Data Transfer Nodes (DTNs); c) intent-based application interfaces providing intuitive access to intelligent SDN services; and d) network measurement, analytics and feedback to build resilience. We argue that this strategy enables us significantly improve the end-to-end performance of science application workflows, creation of end-site driven intelligent services, and enables new paradigms such as creation of dynamic, distributed ‘Superfacilities’. The programmability and auto-configuration of resources provided by this approach gets around the current limitations of manual provisioning for the last mile (end-site networks, Science DMZ resources). Additional benefits include a framework for development of custom end-to-end network services.  A successful outcome of our approach would have a significant impact on networked DOE science.

Abstract Diagram

The following diagram describes the abstract components aka Resource Manager Role and Orchestrator Role being researched, specified and developed through the SENSE project. The purview of the Orchestrator is multi-domain and end-to-end, with simplifying focus for this project being between Site DTNs to Site DTNs belonging to a Science DMZ.
