A system, method and computer program product for implementing network connection failover during application service interruption. While the application is quiesced, a network socket that terminates a network connection to a network peer is maintained on behalf of the application. The socket's network connection state information is sustained by providing acknowledgements of incoming network traffic to the network peer that prevent the peer from terminating the connection. Upon restart, the application is brought up with a blocked socket. The state of the blocked socket is conformed to a current network connection state of the original socket and the blocked socket is unblocked.

There is provided an intelligent electronic device for responding to user data and information requests regarding power usage and power quality for any metered point within a power distribution system. The intelligent electronic device includes a first network interface which receives client side information and data requests, which are processed in accordance with a network protocol and forwarded to a network interface via a network socket interface translator which translates management signals to facilitate the eventual data transfer. Protocol routines process the requests by constructing an internal data request in certain cases and forwards the internal data request to a data interface for translation from an internal data request format of the protocol routine format to a native database format. The database receives the translated request, and retrieves the requested data from a measuring unit of the electric power meter, and forwards the data back to the requesting client.

Methods and apparatuses, including computer program products, are described for transparent recovery of transport connections. The method includes collecting a state associated with a first connection between a first server and a remote server via a first network socket and transmitting the state from a first networking module to a second networking module.

The method includes receiving packets associated with the acknowledgment from the remote server, and modifying the received packets to acknowledge the request to initiate the second connection.

A method for enforcing a network policy is described herein. In the method, a network socket event request from an application executing in a first context is intercepted by an agent prior to the request reaching a transport layer in the first context. A context refers to virtualization software, a physical computer, or a combination of virtualization software and physical computer. In response to the interception of the request, the agent requests a decision on whether to allow or deny the network socket event request to be communicated to a security server executing in a second context that is distinct from the first context. The request for a decision includes an identification of the application. The agent then receives from the security server either an allowance or a denial of the network socket event request, the allowance or denial being based at least in part on the identification of the application and a security policy. The agent blocks the network socket event from reaching the transport layer when the denial is received from the security server. In one embodiment, the method is implemented using a machine readable medium embodying software instructions executable by a computer.

A message gate is the message endpoint for a client or service in a distributed computing environment. A message gate may provide a secure message endpoint that sends and receives type-safe messages. A gate may have a gate name that is a unique ID that refers only to the gate. A gate may be implemented as a layer above a device's transport layer (e.g. networking sockets). The gate name for each gate may be bound to a transport reference. Multiple gates may share the same message transport. The transport reference may be a transport URI or socket reference and may provide a mechanism for naming an underlying transport and sharing the transport with other gates. Multiple local gates may include a reference to the same transport, however, each local gate may behave independently of the other local gates sending and receiving messages to and from its paired remote gate.

A performance monitoring network device provides the performance information. The performance monitoring device stores information about the performance of a plurality of communication links used by sockets of communications devices in the network, and inserts the performance information for particular sockets into associated packets before transmitting the packets to corresponding communication devices.
