Abstract: 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.

Abstract: Techniques are disclosed herein for reconciling planned data for a network (such as a fiber optic network) with data describing the deployed network. Network probing and planning components obtain a snapshot of the deployed network and organize the snapshot into three “layers”: the “link layer,” which represents the physical links that underlie the network, the “digital layer,” which includes optical channel groups that divide the total capacity of the physical links, and the “service layer,” which includes the services delivered over the network. The techniques involve comparing the planned data to the deployed data in the order of link layer, digital layer, and service layer. Differences considered to be “minor” are reconciled automatically. Differences that are “major” are reconciled after receiving instructions from a planner or administrator regarding whether to update the planned data based on what was originally in the planned data or what is in the deployed network.

Abstract: A device may receive information that identifies an initial network topology, to be used to reconfigure a network. The initial network topology may describe an optical layer and an internet protocol layer of the network. The internet protocol layer of the network may include an internet protocol node. The device may determine a reconfiguration criterion associated with the initial network topology. The device may determine a reconfiguration technique to be used to reconfigure the network. The device may perform the reconfiguration technique. The device may generate a reconfigured network topology based on performing the reconfiguration technique. The reconfigured network topology may describe a reconfigured internet protocol layer and a reconfigured optical layer. The reconfigured internet protocol layer may be reconfigured based on the optical layer. The reconfigured network topology may be reconfigured based on the initial network topology. The device may provide the reconfigured network topology.

Abstract: A device receives network information associated with a network to be planned and including a multiple traffic requirements for the network, and identifies the multiple traffic requirements in the network information. The device allocates a first route in the network for a traffic requirement of the multiple traffic requirements, and determines that a second route for at least one other traffic requirement, of the multiple traffic requirements, is removed based on the route for the traffic requirement. The device allocates a third route in the network for the at least one other traffic requirement, and allocates additional routes in the network for remaining traffic requirements of the multiple traffic requirements. The device generates a network plan for the network based on the first route, the third route, and the additional routes allocated in the network, and outputs or stores the network plan.
