Disclosures herein describe a record and replay regression and unit test automation framework for simulating any hardware on a virtual machine to achieve thorough, affordable and efficient software testing. According to the disclosures herein, the test automation framework includes a recording stage where input and output messages for all the interfaces for a process (e.g., an embedded system or any software system or process) running on the original hardware may be recorded along with metadata in a space-optimized and efficient manner. The testing framework also includes a replay stage using innovative thread synchronization approaches that leverage the metadata to simulate the environment for the recorded embedded process in isolation, which may be done on an inexpensive machine or hardware. Thus, the original custom hardware, which may be expensive and costly to run, is not needed for the replay phase of testing.

Methodology for unit test and regression framework

In the disclosed method, a current state of a network device indicative of no license key being associated with a network device is stored in a license database. Information indicative of a master state of the network device is received, via an input port, including at least one license key associated with the network device. The current state of the network device is updated to include the at least one license key associated with the network device, and the updated current state is stored in the license database.

License management system

A device may receive health information associated with a network circuit included in an optical network. The device may determine, based on the health information and network circuit information associated with the network circuit, that the network circuit is experiencing a health issue. The device may identify a diagnostic technique to be applied to the network circuit based on determining that the network circuit is experiencing the health issue. The device may automatically and iteratively apply the identified diagnostic technique to the network circuit in order to identify a fault location. The device may determine a corrective action, associated with the network circuit, based on the fault location and the health issue. The device may provide information associated with the corrective action to cause the corrective action to be taken.

Circuit diagnostic manager

A license management system comprises at least one processor capable of executing processor-executable code coupled with a non-transitory processor-readable medium storing a master license database and processor-executable code for causing the processor to: (a) store a master state of a network device indicative of at least one license key associated with the network device in the master license database; (b) access information indicative of a license key request for the network device subsequent to the storing of the master state, the license key request including a current state of the network device; (c) compare the master state of the network device with the current state of the network device; and (d) in response to the master state differing from the current state of the network device, generate an error message and store the error message in non-transitory processor-readable medium.

A computer system comprising a display, one or more computer readable medium storing a computer application comprising computer executable code for creating a graphical user interface, one or more processors receiving and executing the computer executable code to provide the graphical user interface on the display, the computer readable medium also storing a testing application comprising computer executable code for activating the graphical user interface, the testing application defining a command execution server embedded into the computer application, and a command client external to the computer application. Upon execution by the one or more processors, the command execution server receives a command for the graphical user interface, enables the execution of the command by the computer application by generating a graphical user interface event in the graphical user interface of the computer application, and sends an acknowledgement to the command client responsive to the completed execution of the command.

Rapid automation front-end framework library and executable graphic user interface testing system and method

Embodiments of the present invention provide systems, devices and methods for improving the efficient deployment and configuration of networking equipment within a network build-out. In certain embodiments of the invention, an iterative analysis of inter-node equipment placement and connectivity, and inter- and intra-node traffic flow is performed to identify a preferred deployment solution. This analysis of deployment optimization takes into account both configurations from a network node perspective as well as from a network system perspective. Deployment solutions are iteratively progressed and analyzed to determine a preferred solution based on both the cost of deployment and satisfaction of the network demands. In various embodiments of the invention, a baseline marker is generated from which the accuracy of the solution may be approximated that suggests to an engineer whether the deployment is approaching an optimal solution.

Network planning and optimization of equipment deployment

Consistent with the present disclosure, a block of software code or 'software code block' that is executed while particular tests are carried out is assigned a software code block identifier, which is associated with test identifiers, which, in turn, identify the tests that were performed. The software code block identifiers and corresponding test identifiers are then stored in a database. When a portion of the software code block is later modified, either by a change to one or more lines of the code or by deleting or adding code, the corresponding software code block identifier is determined or selected, and then used to access the corresponding test identifiers from the database. The test identifiers are then used to generate a report, for example, that lists each test to be performed in order to determine whether the modified software code block operates properly. The above processes of assigning and storing software code block identifiers and test identifiers may be automated, thereby increasing the likelihood that a complete set of correct tests are performed on the modified software code block. As a result, reliability of the software is improved.

Accurate identification of software tests based on changes to computer software code

An article including at least one computer readable medium storing a network management application comprising computer executable code that upon execution by one or more processors causes the one or more processors to receive and execute the computer executable code of the network management application to store an identifier indicative of a candidate service in a database, receive the information indicative of managed entities from the one or more input devices, transform the data indicative of the managed entities into neutral data structure represented by graphs, vertices and edges, store these neutral data structures in the database and determine whether the telecommunication network is configured to execute the candidate service by applying predetermined rules on these neutral data structures.

Graph based flexible service discovery and management system and method

In accordance with the present disclosure, a method of configuring a wavelength division multiplexed (WDM) network is presented. The WDM network includes circuits that carry optical signals, with each signal corresponding to a wavelength. The WDM network includes nodes, with links connecting the nodes to one another. Each circuit includes at least one link and at least one node. The method comprises assigning each of the circuits to an optical signal, based on first and second criteria, and configuring the nodes based on the assignment.

Method for wavelength assignment in a WDM network

A system, apparatus and method are described for displaying multiple attributes relative to objects in a network management program. In one embodiment, multiple attributes from a plurality of different standards are coalesced together and the coalesced attributes are displayed by a user interface. These coalesced attributes may be shown in such a manner so that inconsistencies between attributes of objects from different standards are reduced or obviated.

Consistency of state model visualization across different standard attributes

A node, of a group of nodes, may detect a failure on a first path; establish a connection associated with a second path when the failure on the first path is detected; store an identifier in a field in an overhead portion of a data frame when the failure on the first path is detected, the data frame including a payload portion that contains a client signal, the identifier instructing another one of the nodes to establish a connection associated with the second path; and transmit the data frame to the other one of the nodes via the second path.

Path-level protection for digitally wrapped payloads

A framework is disclosed which enables a management system to manage completely different type of network elements (NEs) running different versions of their embedded software by introducing generic operational interfaces, generic data interfaces, information descriptors and self adaptive control mechanism. This Management system framework consists of mainly two parts a) core application and b) element-dependent components and c) a set of generic interfaces. When the management system is launched, it executes the core application. The core application comprises of network element independent version independent generic functionalities that can be used to interact with a variety of network elements and a dynamic control mechanism to make selection and placement of pluggable components at appropriate time and place during execution. After the core application is executed, whenever a need to manage one or more network elements, self adaptive control mechanism will take decision based on information descriptor of that target NE and NE type dependent version dependent modules are incorporated or 'plugged in' with core application to produce an overall management mechanism to manage that target NE.

Framework for enabling dynamic construction of a network element management mechanism

A method of interfacing with managed objects in a communication network, including: receiving an application independent request for service using generically represented data; mapping the request to a registry to determine the particular service application that can process the requested service; and executing the service application that can process the requested service. A network element in a communications network, includes: a managed object manager configured to map an application independent request for service and to forward the request to a service application that can process the requested service; and a registry coupled to the managed object manager and configured to provide mapped results that indicate the service application that can process the requested service.
