Abstract: Customized feature vectors are used to train a machine learning algorithm to automatically identify a network component where a network fault has occurred. A database comprising network components and associated network faults is analyzed to select a set of network components associated with the largest quantity of network faults. Customized features associated with the network faults are identified and selected for use in a feature vector as input to a machine learning algorithm. The features are selected based upon analysis of consistency checks, component configuration limits, and network wide configurations.

Abstract: A computer-implemented method includes: obtaining platform dependent data and platform independent data from each of a plurality of first network devices for a computer network environment. The received platform dependent data and platform independent data are converted to key-value pairs. Sequences of the key-value pairs representing the configurations and states of the respective first network device are created. Vectors for the sequences of the key-value pairs are generated in a vector space. The vectors are supplied to a model to train the model to learn relationships of the platform dependent data and platform independent data of each of the plurality of first network devices. Platform dependent data and platform independent data from one or more second network devices are supplied to the trained software model to determine consistency of configurations and states of the one or more second network devices.

Abstract: Techniques are provided for bifurcating database information that might otherwise be replicated on each switch in a switched fabric of a Storage Area Network (SAN). The database is divided into a control plane database that comprises mostly switch specific data and a central management database that comprises user device configurations and device profiles. The control plane database includes information such as name server and zone server information, for those devices that may locally log into the switched fabric via a given switch, and those remote devices that are zoned with those local devices and that may log into the switched fabric via another switch. The central management database includes global information for the switched fabric and device profile information (e.g., login interface, Virtual SAN membership, device aliasing, etc.) for devices that have access to the switched fabric and that can also be requested by the various switches in the switched fabric.

Abstract: In one example embodiment, a time unconstrained fabric switch software upgrade function is described for an in-switch-software-upgrade/downgrade (ISSU) in a network switch. Prior to an ISSU, Hello protocol data unit (PDU) information is stored for relevant control protocols of associated interfaces of the switch. The Hello PDU information comprises information on messages and data exchanged by the control protocols that may be used to maintain communications links of the switch. During the configuring of the ISSU, and while the control plane of the switch is, at least partially, dysfunctional, Hello PDUs are sent on the interfaces according to the stored PDU information in order to maintain the communication links. The Hello PDU information may include a time interval value for each relevant protocol that determines when Hello PDUs are sent.
