Abstract: Systems, methods, and non-transitory computer-readable storage media for managing routing information in overlay networks. A first tunnel endpoint in an overlay network may receive an encapsulated packet from a second tunnel endpoint. The encapsulated packet may have been encapsulated at the second tunnel endpoint based on another packet originating from a source host that is associated with the second tunnel endpoint. The encapsulated packet can include a source host address for the source host and a source tunnel endpoint address for the second tunnel endpoint. The first tunnel endpoint can then update a lookup table based on an association between the source host address and the source tunnel endpoint address.

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: Techniques are provided to decouple service chain structure from the underlying network forwarding state and allow for data plane learning of service chain forwarding requirements and any association between services function state requirements and the forward and reverse forwarding paths for a service chain. In a network comprising a plurality of network nodes each configured to apply a service function to traffic that passes through the respective network node, a packet is received at a network node. When the network node determines that the service function it applies is stateful, it updates context information in a network service header of the packet to indicate that the service function applied at the network node is stateful and that traffic for a reverse path matching the classification criteria is to be returned to the network node.
Abstract translation: 提供了技术来将服务链结构与底层网络转发状态分离，并允许服务链转发要求的数据平面学习和服务功能状态要求与服务链的前向和后向转发路径之间的任何关联。 在包括多个网络节点的网络中，每个网络节点被配置为对通过相应网络节点的业务应用服务功能，在网络节点处接收分组。 当网络节点确定其应用的服务功能是有状态时，它更新分组的网络服务报头中的上下文信息，以指示在网络节点处应用的服务功能是有状态的，并且用于与分类标准匹配的反向路径的业务 将被返回到网络节点。

Abstract: Systems, methods, and computer-readable media for updating configurations in sensors deployed in multi-layer virtualized environments. In some examples, a system can track information of sensors and collectors in the network. In response to determining that a specific collector becomes unavailable (e.g., the specific collector is down, offline or becomes unsupported), the system can determine affected sensors corresponding to the specific collector, determine a new collector among active collectors of the network for each of the affected sensors, and dynamically update configuration and settings of the affected sensors to maintain proper collector-to-sensor mappings and other settings on the affected sensors.

Abstract: Systems, methods, and computer-readable media for managing compromised sensors in multi-tiered virtualized environments. In some embodiments, a system can receive, from a first capturing agent deployed in a virtualization layer of a first device, data reports generated based on traffic captured by the first capturing agent. The system can also receive, from a second capturing agent deployed in a hardware layer of a second device, data reports generated based on traffic captured by the second capturing agent. Based on the data reports, the system can determine characteristics of the traffic captured by the first capturing agent and the second capturing agent. The system can then compare the characteristics to determine a multi-layer difference in traffic characteristics. Based on the multi-layer difference in traffic characteristics, the system can determine that the first capturing agent or the second capturing agent is in a faulty state.

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: The present disclosure provides systems, methods, and computer-readable media for implementing security polices at software call stack level. In one example, a method includes generating a call stack classification scheme for an application, detecting a call stack during deployment of the application; using the call stack classification scheme during runtime of the application, classifying the detected call stack as one of an authorized call stack or an unauthorized call stack to yield a classification; and applying a security policy based on the classification.

Abstract: A method provides for receiving network traffic from a host having a host IP address and operating in a data center, and analyzing a malware tracker for IP addresses of hosts having been infected by a malware to yield an analysis. When the analysis indicates that the host IP address has been used to communicate with an external host infected by the malware to yield an indication, the method includes assigning a reputation score, based on the indication, to the host. The method can further include applying a conditional policy associated with using the host based on the reputation score. The reputation score can include a reduced reputation score from a previous reputation score for the host.
