摘要： The present technology provides a framework for user-guided end-to-end automation of network deployment and management, that enables a user to guide the automation process for any kind of network deployment from the ground up, as well as offering network management, visibility, and compliance verification. The disclosed technology accomplishes this by creating a stateful and interactive virtual representation of a fabric using a customizable underlay fabric template instantiated with user-provided parameter values and network topology data computed from one or more connected network devices. A set of expected configurations corresponding to the user-specified underlay and overly fabric policies is then generated for deployment onto the connected network devices. Network deviations from the intended fabric policies are addressed by the provision of one or more configuration lines to be deployed onto or removed from the connected network devices to bring the network state in agreement with the set of expected configuration.

摘要： Techniques for a configuration change service to transition a network controller into a frozen state, causing network users submitting configuration changes associated with the network to refrain from deploying the configuration changes for a period of time are disclosed. A first user configured as a stager role may submit data representing a proposed change to the configuration change service, where the proposed change may be stored in association with a list of proposed changes. A second user configured as an approver role may submit data representing an approval or disapproval of the proposed changes to the configuration change service, where a modified list of proposed changes may be generated. A third user configured as an administrator role may submit data configured to transition the controller to an unfrozen state and/or deploy the changes included in the list of proposed changes to the network controller, subsequent to the period of time.

摘要： The present disclosure provides systems, methods, and non-transitory computer-readable storage media for determining container to leaf switch connectivity information in a data center in a presence of blade switches and servers. In one aspect of the present disclosure, a method of determining container to leaf switch connectivity information of a data center utilizing at least one blade switch and at least one blade server, includes receiving, at a network controller, link connectivity information that includes south-bound neighboring information between the at least one blade switch of the data center and the at least one blade server of the data center; determining, at the network controller, the container to leaf switch connectivity information of the data center, based on the link connectivity information; and generating a visual representation of a topology of the data center based on the container to leaf switch connectivity information.

摘要： In one embodiment, a device obtains temperature and utilization measurements for a set of network interface transceivers in a network. The device computes, for each of the transceivers, a correlation coefficient between its temperature and utilization measurements. The device applies a k-nearest neighbor classifier to the correlation coefficients, to predict a correlation coefficient. The device uses the predicted correlation coefficient to determine an impact of temperature on utilization of a particular network interface transceiver. The device initiates a mitigation action, when the determined impact of temperature on the utilization of the particular network interface transceiver exceeds a predefined threshold.

摘要： Techniques for virtual workload deployment based on computing resource hardware load and associated network hardware load. For each of a plurality of computing resources within one or more data centers onto which a virtual workload can be deployed, a computing resource hardware load of the respective computing resource is determined. Network topology information is maintained for at least one network fabric of the one or more data centers, and an associated network hardware load of a network device communicatively connected to the respective computing resource is determined. Embodiments automatically select one or more computing resources. The virtual workload is deployed onto the automatically selected one or more computing resources.

摘要： In accordance with one example embodiment, there is provided a system configured for virtual local area network (VLAN) blocking on a virtual port channel (vPC) member link to handle discrepant virtual network instance (VNI) to VLAN mappings. In other embodiments, the system can be configured for providing Virtual Switch Interface Discovery Protocol (VDP) and virtual switch enhancements to accommodate discrepant VNI to VLAN mappings. In another example embodiment, an apparatus is provided that includes a processor, and a memory coupled to the processor, where the apparatus is configured such that if a server is connected through a virtual port channel, a VDP is used to notify the server of different VNI to VLAN mappings. In another embodiment, the apparatus can extend a VDP Filter Info Field to carry a set of VLANs mapped to a VNI, keyed by leaf MAC addresses that serve as bridge identifiers.
