    Abstract: A method is provided in one example and includes communicating a first request message to a first network element functioning as a point of local repair for a backup label switched path. The first request message includes a first network address having a predetermined value and an indication of a forwarding equivalence class associated with the backup label switched path. The method further includes receiving a first reply message from the first network element. The first reply message includes at least one backup path parameter associated with the backup label switched path.

    Abstract: Techniques are described herein for managing access to sensitive data detected within an electronic communication. In some embodiments, such techniques may comprise receiving, from a sender, an electronic communication directed toward a first recipient. The techniques may then comprise identifying one or more pieces of sensitive data within the electronic communication, providing a content of the one or more pieces of sensitive data to a data hosting device to be stored in a memory location and first information associated with the first recipient used to access the memory location, updating the electronic communication to replace the one or more pieces of sensitive data with a reference to the memory location, and transmitting the electronic communication to the first recipient.

    Abstract: This disclosure describes techniques for policy validation techniques relating to data traffic routing among network devices. The techniques may include processing a validation request from a controller. A validation request may include information related to a computed path for routing data traffic in a computing network. The processing may include sending one or more path requests to one or more redundant controllers, and comparing computed paths from the redundant controller(s) to the originally computed path. The techniques may include generating a validation response based on comparing the computed paths. In some examples, the techniques may further include determining a health score for the controller. Policy validation techniques may improve data traffic routing among network devices by helping to ensure valid policies are produced.

    Abstract: A method performed by a controller configured to communicate with one or more cloud platforms that are configured to host application components, which are configured to implement user services over a network, the method comprising: generating an application dependency mapping of the application components; collecting traffic flow data to identify data transfers between the application components; defining an application boundary around particular application components of the application components in the application dependency mapping; overlaying the application dependency mapping, the traffic flow data, and the application boundary, to identify particular data transfers between the particular application components; computing a network cost based on individual costs of the particular data transfers; and adding, to the network cost, compute and storage costs for the particular application components, to produce a total cost of using the particular application components.

    Abstract: Techniques for adaptive thresholding are provided. A first data point in a data stream is received, and a first plurality of data points from the data stream is identified, where the first plurality of data points corresponds to a timestamp associated with the first data point. At least a first cluster is generated for the first plurality of data points, and a predicted value for the first data point is generated based at least in part on data points in the first cluster. A deviation is computed between the predicted value for the first data point and an actual value for the first data point. Upon determining that the deviation exceeds a first predefined threshold, the first data point is labeled as anomalous, and reallocation of computing resources is facilitated based on labeling the first data point as anomalous.

    Abstract: This disclosure describes using a dynamic proxy for securing communications between a source within a cloud environment and an application container. The techniques include intercepting traffic directed to an application container, analyzing the traffic and traffic patterns, and allowing or preventing the traffic from being delivered to the application container based on the analysis. A traffic analysis engine may determine whether the traffic is considered safe and is to be allowed to be delivered to the application container, or whether the traffic is considered unsafe and is to be prevented from being delivered to the application container, According to some configurations, the address(es) to the network interfaces (e.g., WIFI or Eth0) are abstracted to help ensure security of the application containers.
