The systems and methods that maintain an IP address of a container when the container is moved from a first node to a second node in a data center are provided. Each node includes a local controller which is communicatively coupled to the central controller. The local controller generates an IP address for a container that executes on the first node. A label unique to the container is also generated on the first node. The local controller then synchronizes the IP address and the label of the container with the central controller. The central controller then passes the IP address and the label to the second node when the container is moved from the first node to the second node, and ensures that the IP address of the container remains the same before and after the move.

Systems and methods for moving network containers in a computer network

Disclosed are a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for event messaging over a network. An identification module receives first data identifying consumer devices available to receive event messages linked to a topic. The identification module receives second data identifying a producer device available to provide event messages linked to the topic. A provisioning module links a plurality of values to respective consumer devices that are linked to the topic. A scheduler module accesses a first data message linked to the topic. The first data message includes a key value. The scheduler module provides the first data message to a selected one of the consumer devices based on a comparison of the key value and the plurality of values of the respective consumer devices.

Processing high volume network data

Disclosed are a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for event messaging over a network. A subscription interface receives data indicative of a subscription request for sessionized data. An allocation module allocates a sessionizer bank linked to the subscription request. A messaging interface module provisions identifiers linked to the respective processing engines of the sessionizer bank. The messaging interface module registers the allocated sessionizer bank as available to process event messages matching the subscription request by providing the provisioned identifiers. The messaging interface module receives event messages from a producer device linked by a collection server to a selected one of the processing engines of the sessionizer bank. The selected one of the processing engine processes the received event messages in accordance with session rule data linked to the subscription request to generate sessionized data.

A first route reflector client manager determines identifies that a distributed lock has been released, wherein the first route reflector client manager corresponds to a first route reflector client. In response to the determining that the distributed lock has been released, the first route reflector client manager retrieves the distributed lock. In response to retrieving the distributed lock the first route reflector client manager provisions the first route reflector client into a first route reflector. The first route reflector client manager advertises information corresponding to the provisioning of the first route reflector client into the first route reflector, wherein the advertising causes at least a second route reflector client to identify the first route reflector client as the first route reflector.

System for dynamic election of route reflectors

In a multicast publisher-subscriber environment, a plurality of receiver machines are managed by a configurator machine. A consumer address of a receiver machine is received from a configurator machine. The consumer address is generated by the configurator machine based on registration data transmitted by the receiver machine. A communication is generated based on the consumer address, the communication indicating an availability of the receiver machine to receive messages that correspond to a topic. The communication is transmitted via a network, and in response to the communication, at least one message is received.

Topic-based messaging using consumer address and pool

In a multicast publisher-subscriber environment, a configurator machine manages a consumer pool of multiple receiver machines. The consumer pool is dedicated to a topic. Each receiver machine has a unique consumer address within the consumer pool allocated by the configurator machine. The configurator machine receives registration data from a receiver machine to be added to the consumer pool and provides a consumer address to the receiver machine. The receiver machine transmits a multicast communication to advertise its availability to receive messages on the topic. The multicast communication includes the consumer address. A transmitter machine may publish a message on the topic. The message may be a multicast communication directed to any receiver machine in to the consumer pool, or the message may be a point-to-point communication directed to the receiver machine with the consumer address.

A mechanism is disclosed for identifying, classifying, and controlling flows in a network. In one implementation, a separate set of behavioral statistics is maintained for each flow. These behavioral statistics are updated as packets belonging to a flow are processed. Whenever a packet belonging to a flow is processed, a set of policies that the flow's behavioral statistics satisfy is determined. For each policy that the flow's behavioral statistics satisfy, actions that are associated with that policy are applied relative to the packet. The actions may be designed to cause a router to handle, in a user-specified manner, packets that are likely to represent a particular kind of traffic. Thus, different flows, such as VOIP, gaming, streaming, and P2P flows, which are associated with different behavioral statistics, may be handled in ways applicable for the specific application traffic type.
