Abstract: A system and method for network planning with certain guarantees is disclosed. The system receives data characterizing various aspects of a backbone network, such as the nodes of the backbone network, how the nodes are connected by network links, the maximum available capacities of the network assets, network costs, and network asset reliability information. The system also receives data characterizing the requirements of different data communications, or flows, within the backbone network. For example, the backbone network may need to provide a flow a minimum amount of bandwidth or throughput, and the flow may have a minimum required uptime or availability. Based on the network data and flow data, the system generates a network plan that describes how capacity should be provided by different components of the network in a manner that guarantees satisfying flow requirements while balancing other considerations, such as network costs.

Abstract: Methods, systems, and storage media for running unified simulations on clusters. Exemplary implementations may include: receiving simulation parameters for a simulation of a cluster; generating synthesized workload events based the simulation parameters of the cluster; determining a memory latency associated with the cluster; determining a reliability and availability of resources in the cluster for a predetermined duration of time; simulating events for jobs in the cluster based on the reliability and availability of resources in the cluster, each job associated with one or more synthesized workload events; and outputting simulation results based on the synthesized workload, the memory latency, and the events.

Abstract: The present disclosure provides systems and methods for operating optical networks and performing defragmentation operations. Embodiments include computer systems and computer program products comprising a computer readable storage and a processor. Upon receiving information indicative of a spectrum assignment on the optical network, a target entity associated with a set of optical channels and a potential spectrum path are identified. The target entity can be defragmented to enable the potential spectrum path, comprising reconfiguring at least one existing spectrum path associated with an optical channel in the set of optical channels. The potential spectrum path may then be reconfigured to a continuous and contiguous band of slice on at least one optical channel associated with the target entity.
