Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide for a data processing system having an efficient network communication infrastructure. The data processing system has a plurality of data processing nodes distributed across a network. Each node comprises a processor and a memory having an application and a routing thread operatively configured to receive a message on the network. The message has an application identifier and a message group identifier. Each application has a command thread and a plurality of message group handlers. Each routing thread is operatively configured to determine whether the received message is for the application on the respective node and to notify the application's command thread of the received message in response to determining that the message is for the application. The command thread then directs the message to one of the message group handlers based on the received message's message group identifier.

Abstract: A method is provided for developing an architecture model for a system-of-systems (SoS) that includes n system levels L1 . . . Ln, each of which includes at least one component of the SoS. For at least i>1, each system level Li includes at least one component of level Li-1. The method includes developing an architecture model for at least one level of the SoS. For at least i>1, the level Li-1 architecture model can be developed by developing a functional architecture model for level Li-1, and thereafter transforming the level Li-1 functional architecture model into a physical architecture model for level Li-1. The functional architecture model includes a functional and a logical structure for level Li-1. And as such, the functional architecture model is developed based upon a concurrent functional and logical decomposition of a functional architecture model developed for level Li.
