A system and method that facilitate secure communication employing dialog session keys that can be shifted unilaterally is provided. A key exchange key can further be employed to encrypt and/or decrypt the dialog session keys that are used to encrypt and/or decrypt message(s) that form a dialog between services. For example, the key exchange key can be unique to a service pair, while a first dialog session key is unique to message(s) originated by a first service, and, a second dialog session key is unique to message(s) originated by a second service. The system allows the dialog session keys to be independently managed by each endpoint (e.g., service). This makes updating the dialog session key very easy and lightweight compared to other messaging systems, where both endpoints must agree on the updated session key. An endpoint can shift the dialog session key for message(s) it originates based on a dialog session key policy (e.g., time-based, upon receipt of a change in the second dialog session key, and/or receipt of shifts of shifts the second dialog session key more than a threshold quantity of times in a given time period).

A system for automatically implementing high-level instructions in a distributed application program, where the high-level instructions reflect the behavior of the distributed application program, includes at least a tools component. The tools component is used to write high-level instructions in the form of declarative models, and place them in a repository. An executive component then receives the declarative models from the repository and refines them (e.g., via progressive elaboration) until there are no ambiguities. A platform-specific driver then translates the commands from the executive component, effectively turning the declarative model instructions into a set of imperative actions to be implemented in one or more application containers. The platform-specific driver also relays one or more event streams to an analytics means, which can result in modifications to the declarative models and corresponding new sets of instructions coming through the platform-specific driver at a later point.

A telecommunications network includes a mobile station that generates wireless telecommunications traffic in radio frames for transmission to a base transceiver station. The mobile station sets a TFCI field in the radio frame to provide a class of service indication for the payload information carried in the radio frame. The TFCI field is set according to a priority of the payload information to be carried in the radio frame. The base transceiver station receives the wireless telecommunications traffic and identifies the class of service indications carried in the radio frame. The base transceiver station encapsulates the radio frame into Internet Protocol packets. The base transceiver station maps the transport format combination indicator field into a differentiated services code point field in header information of the Internet Protocol packets. The base transceiver station forwards the Internet Protocol packets to a base station controller over an Internet Protocol network according to the identified class of service indication in the differentiated services code point field.

It allows users to explore and manipulate data using a branch explore merge paradigm via a combination of personal display spaces to create shared display spaces and segregation of personal displays thereof on-demand using interaction modalities like hand gestures, laser pointers and even personal devices. The result is a paradigm where the displays are used as mediums for interacting with the data.

The invention discloses a disaster monitoring and early warning platform construction method based on an SOA architecture. By using existing geological disaster monitoring and early warning, early warning is performed through manual inspection and monitoring and monitoring equipment threshold alarm; but due to the diversity and the uncertainty of factors inducing geological disasters, complex geographical environment factors are usually interpenetrated and blended and data management and evaluation become extremely difficult. By using the method of the invention, the above defect is solved. The low coupling characteristic of the SOA architecture is fully used to integrate an AI early warning service with the monitoring system, and simultaneously the advantage of a machine learning algorithm which is used to process complex data and accurate classification is used so that the data of each monitoring object is monitored in real time based on the risk assessment of a risk source and monitoring object evaluation. The grades of a series of geological disasters with different intensities which may occur in a danger area for a certain period of time are predicted, and for the characteristics of different risk areas, the various countermeasures of risk reduction are proposed to provide an auxiliary decision for the geological disaster monitoring and early warning.
