Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.

Abstract: Determining and presenting traffic patterns includes: obtaining a first set of traffic metrics pertaining to network traffic associated with a plurality of containers of a container-based cloud computing platform, wherein: the plurality of containers supports a plurality of microservices; and a microservice has one or more corresponding microservice instances that execute on one or more of the plurality of containers; transforming the first set of traffic metrics into a second set of traffic metrics, the second set of traffic metrics comprising network traffic information pertaining to at least some of the plurality of microservices, the transformation being based at least in part on information pertaining to the plurality of containers and the plurality of microservices supported by the plurality of containers; constructing a microservice map based on the second set of traffic metrics; and outputting the microservice map.

Abstract: Network session identification information is received. The network session identification information is associated with a destination IP address and a destination network port. An available source network port for a new session to be established for a source IP address is determined based on the destination IP address and the destination network port.

Abstract: A method of controlling a packet flow in a distributed network system comprising a plurality of network nodes having the same destination address is disclosed. Network nodes each having an application running that waits for connections on a given destination port are registered in a flow table. This registration information is distributed to each of the plurality of network nodes. When a packet indicating an initiation of a connection is received and it is determined that the received packet indicates the initiation of the connection on the given destination port, a network node is selected from the network nodes registered in the flow table, to which the received packet is to be forwarded. The received packet is forwarded to the selected network node and a corresponding entry is inserted into the flow table. This entry information is distributed to each of the plurality of network nodes.

Abstract: There is disclosed a distributed platform that includes a plurality of nodes for controlling a data flow. According to this distribution platform, at least one of the plurality of nodes supports multiple instances. Also according to this platform, there is provided means for distributing classification rules for any given instance between nodes sharing the instance.

Abstract: A system and method is directed to updating a route table in a distributed routing platform, thereby enabling multiple routing protocols to be executed on different routing modules. A slave route distributor on one routing module is configured to receive a route from a local route table and flow manager. The slave route distributor communicates the route to a master route distributor on another routing module by way of an inter process communications protocol. The master route distributor provides the route to its local route table and flow manager, where a determination is made whether the route is a best route. If the route is a best route, the master route distributor updates its external routing table. The master route distributor also distributes the route to another slave route distributor on yet another routing module, where the route enables an update to a remote routing protocol, and routing table.
