摘要:
A mechanism is provided for network communication. The mechanism establishes a connection between a network server and a network client. The connection is established using a connection-oriented protocol. The network server has a first server configuration stored in a memory of the network server. The first server configuration comprises a set of server parameters specific to a network application that the network server provides to the network client. The mechanism identifies the network client configuration. The mechanism replaces, in the memory of the network server, the first server configuration with a second server configuration. Responsive to a determination that the client configuration is incompatible with the second server configuration, the mechanism disconnects the network client.

Message integrity in a messaging oriented middleware system is preserved by determining a message producer's level of message integrity by examination of connection details between the message producer and a messaging engine. The message producer's level of integrity is stored in a memory of the messaging engine. The message is then stored in the designated destination using the message producer's level of integrity. The message is sent from the designated destination to a consumer when it is determined that the consumer conforms to the integrity levels.

A method of assisting a user, for use in an environment comprising: a user session, an external entity session and a forms engine for generating a form. The method comprises the steps of: registering with the user session, wherein a first session is established between the user session and the forms engine; receiving a request for assistance from a user; in response to receiving the request, de-registering with the user session, wherein the first session is un-established; registering with the external entity session, wherein a second session is established between the external entity session and the forms engine; receiving input from the external entity session; and populating the form with the received input.

There is disclosed a method, apparatus and computer program for modifying a message. A message is received from a first entity. The message contains a first level of detail appropriate to the first entity and the message is for communication to a second entity. It is determined whether the message contains a scope sensitive field. Once it has been determined that the message does contain a scope sensitive field, information is accessed indicating how to transform the scope sensitive field to a second level of detail appropriate to the second entity. The scope sensitive field is then transformed to produce the second level of detail.

A method and system for controlling message throughput rates of clients connected to a broker device in a publish/subscribe network are disclosed. The broker device determines a maximum allowable message throughput for each client connected to the broker device. If a message-producing rate of a client exceeds the maximum allowable message throughput of the client, the broker device sends a negative acknowledgement (NACK) packet to the client and messages from the client are not accepted at the broker device. The NACK packet includes a maximum allowable message throughput of the client, so the client can adjust its message-producing rate based on the maximum allowable message throughput of the client. The present invention can be applied to a publish/subscribe network as well as a TCP/IP network.

Methods support a sleep mode for an embedded device. Embedded devices like sensors and actuators used in wireless sensor networks have a limited power supply. To conserve energy and thus increase the lifetime of these devices, the devices should be put into a stand-by mode (also called sleep-mode) when they are not used. These methods support the sleep mode at a higher level than the MAC layer, thus avoiding the problems of prior art approaches. Methods are exemplarily described for the case of the message queuing telemetry transport protocol for sensor networks. They can easily be adapted to other protocols.
