Abstract: Systems, methods, and non-transitory computer-readable storage media for translating source addresses in an overlay network. An access switch in an overlay network, such as a VXLAN, may receive an encapsulated packet from a tunnel endpoint in the overlay network. The encapsulated packet may originate from a host associated with the tunnel endpoint and be encapsulated at the tunnel endpoint with a first source tunnel endpoint address and a destination tunnel endpoint address. The access switch may replace the first source tunnel endpoint address in the encapsulated packet with a second source tunnel endpoint address of the access switch to yield a translated packet. The access switch may then transmit the translated packet towards the destination tunnel endpoint address.

Abstract: The technology visualizes data flows within a datacenter in an interactive hierarchical network chord diagram. Based on analyzed data describing data flows, a portion of the data flows that originate at the same first endpoint and terminate at the same second endpoint can be grouped. Subsequently, the dataflow monitoring system displays an interactive hierarchical network chord diagram to include a chord with a first endpoint and a second endpoint. The chord represents the grouped portion of data flows that originate at the same first endpoint and terminate at the same second endpoint. Upon receiving a selection of the chord or the first endpoint of the chord, the dataflow monitoring system expands the grouped portion of the data flows into a more granular representation of the network.

Abstract: According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.

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: 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.

Abstract: Systems, methods, and computer-readable media for hierarchichal sharding of flows from sensors to collectors. A first collector can receive a first portion of a network flow from a first capturing agent and determine that a second portion of the network flow was not received from the first capturing agent. The first collector can then send the first portion of the network flow to a second collector. A third collector can receive the second portion of the network flow from a second capturing agent and determine that the third collector did not receive the first portion of the network flow. The third collector can then send the second portion of the network flow to the second collector. The second collector can then aggregate the first portion and second portion of the network flow to yield the entire portion of the network flow.

Abstract: Application dependency mapping can be automated in a network. The network can capture traffic data for flows passing through the network using a sensor network that provides multiple perspectives for the traffic. The network can analyze the traffic data to identify endpoints of the network. The network can also identify particular network configurations from the traffic data, such as a load balancing schema or a subnetting schema. The network can partition the endpoints based on the network configuration(s) and perform similarity measurements of endpoints in each partition to determine clusters of each partition. The clusters can make up nodes of an application dependency map, and relationships between and among the clusters can make up edges of the application dependency map.
Abstract translation: 应用程序依赖关系映射可以在网络中自动化。 该网络可以捕获通过网络的流量的流量数据，该传感器网络为流量提供多个视角。 网络可以分析流量数据以识别网络的端点。 网络还可以从流量数据识别特定的网络配置，例如负载平衡模式或子网模式。 网络可以基于网络配置对端点进行分区，并对每个分区中的端点进行相似度测量，以确定每个分区的集群。 集群可以构成应用程序依赖关系映射的节点，并且集群之间和之间的关系可以构成应用程序依赖关系映射的边。

Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.

Abstract: A monitoring device/module monitors a plurality of nodes in a data center network, and determines one or more latency distributions of response times for messages exchanged between pairs of nodes of the plurality of nodes. The network monitoring device determines a network topology, including one or more communication links interconnecting nodes of the plurality of nodes, consistent with the one or more latency distributions. The network monitoring device also determines a representative response time for each communication link based on the one or more latency distributions, and compares a current response time a message exchanged between one pair of nodes to the representative response time for the communication link interconnecting the one pair of nodes. The network monitoring device identifies a network anomaly when the current response time deviates from the representative response time for the communication link interconnecting the one pair of nodes by a threshold amount.
