Abstract: A system for routing an application message detects that routing rules are dynamic and static. The system then invokes a rules engine to receive the dynamic routing rules and interleaves the dynamic routing rules with static routing rules. The system then executes the interleaved rules to route the message.

Abstract: A method and network switch for switching data units assigns a unique virtual port to each end-node operating on a physical machine connected to a physical port of network switch. A data unit, sent by a given end-node operating on the physical machine, is received at the physical port. The received data unit is switched to the virtual port assigned to the given end-node. Based on the virtual port assigned to the given end-node, the data unit is switched to a second physical port of the network switch for subsequent forwarding of the data unit towards its destination.

Abstract: Embodiments of the present invention enable processing of tasks within a service-oriented architecture (SOA). In embodiments, an echo mediator is a mediator SOA component that acts as a service provider by processing a service request associated with a service requester and returning the result to the service requester. In embodiments, an echo mediator handles a received sequential service request by synchronously processing it. In embodiments, an echo mediator handles a received parallel service request by storing it in a persistent store, and an echo mediator with processing capacity retrieves the stored parallel service request and asynchronously processes it. In embodiments, a group of echo mediators may be distributed among the nodes of a grid, forming an echo mediator grid in which each of the echo mediators interfaces with a common data store deployed within the grid. In embodiments, the grid of echo mediators balances the processing of stored service requests.

Abstract: A data center includes a physical host machine operating a virtualized entity and a network switch having a physical port connected to the physical host machine. To configure the network switch, the network switch has a management module that acquires information about the virtualized entity operating on the physical host machine. The network switch associates the acquired information about the virtualized entity with the physical port, assigns the virtualized entity to a group associated with a traffic-handling policy, and processes packet traffic from the virtualized entity in accordance with the traffic-handling policy. The virtualized entity can be, for example, a virtual machine or a multi-queue network input/output adapter operating on the physical host machine.

Abstract: One embodiment relates to a method of processing packets by a network stack. A first data packet is received from a client via a network, and a network buffer is allocated for the data packet. An indication is given that the data packet is ready for reading by an application. In addition, the network buffer is cached in a network buffer cache. Subsequently, response data may be received from the application, and the network buffer may be re-used from the network buffer cache. The response data may be sent in a second data packet to the client via the network. Finally, the network buffer may be freed. Other embodiments, aspects, and features are also disclosed.

Abstract: Additional synonym pairs are inferred from a pair of schema elements (of different schemas) mapped by a user, and the inferred pairs are added to a dictionary. According to one aspect of the present invention, a mapped pair is inferred as a synonym pair if the elements of the mapped pair cannot be mapped according to a program logic otherwise. According to one more aspect of the present invention, the parents of the mapped elements are also inferred as synonym pairs if sufficient peer (to the mapped elements) elements are already mapped or considered synonyms.

Abstract: Determining data elements for possible mapping in heterogeneous schema definitions. According to one aspect of the present invention, a user indicates whether two non-leaf elements (in respective schemas) are structurally similar, and the probability of possible match of a first element (in a first schema) and a second element (in a second schema) as a synonym pair is computed to be more if the two elements are below the respective ones of the structurally similar nodes, compared to in a situation in which the elements are not present in such hierarchies.

According to one more aspect of the present invention, the parents of the mapped elements are also inferred as synonym pairs if sufficient peer (to the mapped elements) elements are already mapped or considered synonyms.
