Abstract: To interconnect research facilities across wide geographic areas, network operators deploy science networks, also referred to as Research and Education (R&E) networks. These networks allow experimenters to establish dedicated circuits between research facilities for transferring large amounts of data, by using advanced reservation systems. Intercontinental dedicated circuits typically require coordination between multiple administrative domains, which need to reach an agreement on a suitable advance reservation. The success rate of finding an advance reservation decreases as the number of participant domains increases for traditional systems because the circuit is composed over a single path. To improve provisioning of multi-domain advance reservations, we propose an architecture for end-to-end service orchestration in multi-domain science networks that leverages software-defined exchanges (SDX) for providing multi-path, multi-domain advance reservations. Our orchestration architecture increases the reservation success rate from approximately 50% using single path to at most 99% when four paths available. We evaluate our solution using GridFTP, one of the most popular tools for data transfers in the scientific community. Additionally, we propose an intuitive interface that domain scientists can use to request science network services from our orchestration framework. Furthermore, we present a federated auditing framework (FAS) that allows an SDX to verify whether the configurations requested by a user are correctly enforced by participating SDN domains, whether the configurations requested are correctly removed after their expiration time, and whether configurations exist that are performing non-requested actions.

Abstract: Smart and connected communities and their associated edge devices are creating new demands on network services. Edge network connectivity is often not resilient to failures, leading to data loss when network devices are isolated by the failure of a single service provider, while other providers are still functional. We propose MetroSDX, a neutral network design that increases the resiliency of edge networks and global and local services, improves isolation of network functions, and preserves data from edge devices when they are disconnected. MetroSDX is a software-defined exchange, a meet-me point for exchanging computing, storage, and networking resources. This work focuses on MetroSDX’s approach to location specific resilience and performance in this multi-network paradigm with an eye towards addressing increased demands from the growing set of connected devices and services which will increasingly and inevitably require communication between and across elements connected to multiple networks.
