A system and method for a flexible, high-speed Managed Detection and Response platform that ingests, parses, normalizes, monitors, and correlates nearly any log source or security tool output. The MDR comprising of a declarative connector service that tags events with appropriate data source labels to facilitating data isolation, proper handling, and provenance across multiple customers and security products but otherwise aggregate alerts into a single data stream for consumption by the MDR SOC operators. A connector service further provides a programmatic (API-based) means to interchange data securely across environments. Event data is aggregated by the Managed Detection and Response platform that then utilizes enhanced log ingest capabilities to process the data allowing SOC operators to be able to write rules against the alerts.

System and method for aggregating and securing managed detection and response connection interfaces between multiple networked sources

A system and method for a highly scalable distributed connection interface for data capture from multiple network service sources. The connection interface is designed to enable simple to initiate, performant and highly available input/output from a large plurality of external networked service's and application's application programming interfaces (API) to the modules of an integrated predictive business operating system. To handle the high volume of information exchange, the connection interface is distributed and designed to be scalable and self-load-balancing. The connection interface possesses robust expressive scripting capabilities that allow highly specific handling rules to be generated for the routing, transformation, and output of data within the business operating system.

Highly scalable distributed connection interface for data capture from multiple network service and cloud-based sources

The present disclosure provides distributed domain network planning systems and methods. The network planning systems and methods include a distributed domain network planning system that adapts planning concepts to networks operated by modern distributed control planes, such as ASON/ASTN, GMPLS, etc. The network planning systems and methods operate on a multi-domain network utilizing a control plane and local planning systems associated with each individual domain in the multi-domain network. The network planning systems and methods also operate on a single domain network utilizing a control plane and local planning systems associated with the single domain network. The network planning systems and methods build on a distributed control plane philosophy that the network is the database of record. There is significant operational value to distributing the planning function of a large network using the systems and methods disclosed herein.

Distributed network planning systems and methods

A method and system of determining a new path through an optical network from a source node to a destination node when a link in an original path fails are disclosed. When a fault on a link is detected, adjoint weights are assigned to each operational link for each node on the original path. A connection cost is determined for each node based on the adjoint weights of the links connected to the node. A new path through the optical network is determined based at least in part on the adjoint weights and the connection costs.

Optical communication network path restoration

Photonic link information collection and advertisement systems and methods enable photonic nodes (e.g., optical amplifiers) to operate within a control plane system in a distributed and real-time manner. For example, the photonic nodes may not require full control plane protocol stacks at each photonic node. In particular, the systems and methods provide a distributed discovery method for photonic links without requiring full participation in the control plane at the photonic nodes. Additionally, the systems and methods include network databases with amplifier configuration information in a control plane enabled network.

Photonic link information collection and advertisement systems and methods

A path computation method includes defining photonic constraints associated with a network, wherein the photonic constraints include wavelength capability constraints at each node in the network, wavelength availability constraints at each node in the network, and nodal connectivity constraints of each node in the network, and performing a constrained path computation in the network using Dijkstra's algorithm on a graph model of the network with the photonic constraints considered therein. An optical network includes a plurality of interconnected nodes each including wavelength capability constraints, wavelength availability constraints, and nodal connectivity constraints, and a path computation element associated with the plurality of interconnected photonic nodes, wherein the path computation element is configured to perform a constrained path computation through the plurality of interconnected nodes using Dijkstra's algorithm on a graph model with the photonic constraints considered therein.

Path computation systems and methods in optical networks

Optical communications systems including grooming, protection, restoration, and migration on a unified network platform, and using a unified control plane. The systems may include combinations of optical bypass and mesh restoration, may include combinations of shared mesh and dedicate protection, and may be combinations of long haul, extended long haul, and ultra long haul systems. The systems may also include a configurable DWDM tier to accommodate dynamic traffic patterns, thereby allowing for increased operational flexibility.
