A device monitors, for a software-defined networking wide area network (SD-WAN) deployment, a set of virtualized network services of the SD-WAN deployment, and applies a set of diagnostic tests to evaluate the set of virtualized network services. The device detects, based on monitoring the set of virtualized network services and in connection with applying the set of diagnostic tests, an event associated with a virtualized network service. The device analyzes, using an analytics model of SD-WAN operation, the event to identify an issue associated with the virtualized network service, and determines, based on the analytics model of SD-WAN operation, a recommendation relating to remediating the issue. The device generates an abstraction layer user interface to represent the set of virtualized network services and to convey the recommendation relating to remediating the issue, and implements, after providing the abstraction layer user interface, the recommendation to remediate the issue.

Virtualized network service management and diagnostics

Systems and methods described herein provide a network tool that discovers device configurations for selected enterprise sites and automatically organizes the data to assist users, so they can build intents for network function policies in enterprise networks. An intent builder performs device discovery of network function (NF) instances in a customer network; retrieves configuration elements from the NF instances; normalizes the configuration elements; and generates a graphical user interface with rule paths based on the configuration elements. The network device receives, via the graphical user interface, user input to map source Internet protocol (IP) addresses in the rule paths to a user label and to map destination IP address in the rule paths to an application label. Based on the user input, the network device presents, via the graphical user interface, consolidated intents and generates vendor-agnostic policy rules from the consolidated intents.

Intelligent and assisted intent builder

A device can receive virtual network function (VNF) data associated with multiple VNFs. The device can generate multiple configuration templates that are to be used by a network design tool that is capable of creating a design of a network for an organization. The device can receive, from a user device, object data associated with network design objects that have been added to or removed from the interface of the network design tool. The device can generate multiple VNF configuration files that allow two or more of the multiple VNFs to be supported by network devices associated with the organization. The device can perform actions associated with configuring two or more of the multiple VNFs onto the network devices to permit the network devices to utilize virtual resources while executing the two or more of the multiple VNFs.

Automatic configuration of virtual network functions

Systems and methods described herein provide unified policy management framework network functions in enterprise networks. The systems and methods store an abstract micro-service template configured from predefined configuration elements; receive descriptive information for a vendor-specific micro-service that corresponds to the abstract micro-service template; solicit first customer labels for at least some of the predefined configuration elements associated with a group of users for a micro-service on a customer network; solicit second customer labels for other of the predefined configuration elements associated with applications used on the customer network; generate a vendor-agnostic micro-service template using the first customer labels, the second customer labels, and the abstract micro-service template; convert, based on the descriptive information, the vendor-agnostic micro-service template into a vendor-specific micro-service template for the customer; and generate, based on the vendor-specific micro-service template, a network policy for enforcement across multiple sites of the customer network.

Intelligent programmable policies for network functions

Techniques described herein may be used to condense a large quantity of Virtual Network Function (VNF) chains (that each correspond to a network service) into a much smaller quantity of VNF records; and extract any of the large quantity of VNF chains from the smaller quantity of network service records. This may be accomplished by assigning a Number (No.) of Services attribute and a Tier attribute into each VNF record. The No. of Services attribute and Tier attribute may enable the VNF records to reference one another such that the larger quantity of VNF chains may, in effect, be entirely represented by the much smaller quantity of VNF records, thereby conserving storage space, streamlining VNF chain management, and reducing the processing and memory capacity required to search, configure, and deploy virtual network services.

Tier based virtual network function chaining design

A network device obtains credentials of a customer associated with multiple different cloud providers of which the customer is a subscriber, and establishes, using the credentials of the customer, a cloud wide area network (WAN) overlay network across multiple different cloud computing networks associated with the multiple different cloud providers. The network device, when establishing the cloud WAN overlay network, spins up multiple virtual routers in the cloud resources of the customer at each of the multiple different cloud computing networks, with a different one of the multiple virtual routers being spun up in each of the multiple different cloud computing networks, where each of the multiple different cloud computing networks is associated with a different one of the multiple different cloud providers, and where the multiple virtual routers route data traffic between the different cloud computing networks via the cloud WAN overlay network.

Cloud WAN overlay network

Systems and methods for managing network resources that include and involve a plurality of communications modules configured to communicate with a corresponding plurality of network resources. Each network resources is configured to generate operational data related to processing therein and to transmit that operational data based on a particular protocol. The systems and methods also include and involve an extraction module configured to communicate with the communications modules based on each particular protocol used thereby to receive the operational data from the plurality of network resources to extract management data from the operational data, and to transmit the management data. An interface module is also included and involved which is configured to receive the management data from the extraction module, to generate standardized data based on the management data and based on a standard protocol, and to transmit the standardized data to an external system for processing (e.g., processing related to network management and monitoring, etc.).
