Abstract: Flow data can be augmented with features or attributes from other domains, such as attributes from a source host and/or destination host of a flow, a process initiating the flow, and/or a process owner or user. A network can be configured to capture network or packet header attributes of a first flow and determine additional attributes of the first flow using a sensor network. The sensor network can include sensors for networking devices (e.g., routers, switches, network appliances), physical servers, hypervisors or container engines, and virtual partitions (e.g., virtual machines or containers). The network can calculate a feature vector including the packet header attributes and additional attributes to represent the first flow. The network can compare the feature vector of the first flow to respective feature vectors of other flows to determine an applicable policy, and enforce that policy for subsequent flows.

Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

Abstract: Systems, methods, and computer-readable media are provided for automatically downloading and launching a new version of software package on components in a network environment. In some examples, an upgrade server of a network environment keeps a copy of all versions of software packages running on nodes or sensors of the network environment, identifications of corresponding nodes or sensors, and public keys associated with the software packages. The upgrade server can authenticate a new version of a software package using a two-step process.

Abstract: An application and network analytics platform can capture comprehensive telemetry from servers and network devices operating within a network. The platform can discover flows running through the network, applications generating the flows, servers hosting the applications, computing resources provisioned and consumed by the applications, and network topology, among other insights. The platform can generate various models relating one set of application and network performance metrics to another. For example, the platform can model application latency as a function of computing resources provisioned to and/or actually used by the application, its host's total resources, and/or the distance of its host relative to other elements of the network. The platform can change the model by moving, removing, or adding elements to predict how the change affects application and network performance. In some situations, the platform can automatically act on predictions to improve application and network performance.

Abstract: An administrator can define or modify one or more service graphs. Next, the administrator can register service appliances along with their device package files with a controller. Then, the controller can establish the capabilities of the service devices, and classify the service devices as legacy or service tag switching (STS) capable devices. Then, the controller can create one or more instances of the service graph, by populating the service nodes into the service graph. Then, the application owner can attach their endpoint groups (EPGs) to the service graphs created by the administrator. Then, a service in the network can be automatically provisioned using the service graph to configure one or more nodes in an associated service chain of the service according to information in the service graph.

Abstract: Systems, methods, and non-transitory computer-readable storage media for forwarding tables for virtual networking devices. The system first identifies local virtual machines hosted on a local host connected to the system, the system having virtual tunneling capabilities. The system then generates a forwarding table for the system. Next, the system populates the forwarding table with local entries including bindings for the local virtual machines hosted on the local host and adds a default route in the forwarding table pointing to a default forwarder function, wherein the default route is configured to handle all non-local traffic relative to the system and the local host.

Abstract: Various embodiments of the present disclosure provide methods for randomly mapping entries in a suitable lookup table across multiple switch devices and/or multiple switch chipsets in each of the multiple switch devices by using two or more independent hash functions. In some embodiments, the number of entries in the lookup table is equal to be the least common multiple of all possible M (i.e., a number of switch devices) choosing R values (i.e., a desired redundancy level).

Abstract: The subject technology addresses the need in the art for improving utilization of network bandwidth in a multicast network environment. More specifically, the disclosed technology addresses the need in the art for extending multipathing to tenant multicast traffic in an IP overlay network, which enables the network to fully utilize available bandwidth for multicast traffic. In some examples, nodes in the overlay network may be connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network.
