Distributed source learning for data communication switch
InactiveUS6870840B1Multiplex system selection arrangementsCircuit switching systemsDistributed sourceUnknown Source
A method and apparatus for accomplishing source learning in a data switch of the type having a plurality of switching modules where each supports one or more external network devices and a backplane interconnecting the switching modules. Each switching module has logic resident thereon for performing distributed source learning, including configuring unknown source addresses “seen” in inbound packets and for notifying the other switching modules that such source addresses were “seen” on a port thereof. Address-port associations are thereby configured on the switch using distributed logic, i.e. without intervention by a centralized management entity. In regard to configuring destination addresses—when a destination address is unknown, packets are delivered over a multicast queue until the destination address is found. Once the destination address is found, a method of flow integrity is used to avoid out of order packet delivery when the device transitions from using a multicast flood queue to a unicast queue.

Asymmetric network elements sharing an anycast address
For a managed network implementing at least one logical router having centralized and distributed components, some embodiments provide a method that better supports the provision of certain network applications and / or services. The method receives at a host implementing (1) a distributed logical router and (2) a plurality of logical switches of a logical network along with other hosts, a message from a first data compute node (DCN) executing on the host. The host logically forwards the message to the distributed logical router that uses a particular anycast internet protocol (IP) address using a first media access control (MAC) address. The distributed router determines that the message requires processing by a centralized logical router (e.g., a service router, edge node, etc.) executing on an edge node host and forwards the message to the centralized logical router using the same anycast IP address and a second, unique MAC address.

Synthetic Partitioning for Imposing Implementation Design Patterns onto Logical Architectures of Computations
ActiveUS20110314448A1Balance computing loadProgram code adaptionSpecific program execution arrangementsLanguage constructComputer architecture
A method and a system for using synthetic partitioning constraints to impose design patterns containing desired design features (e.g., distributed logic for a threaded, multicore based computation) onto logical architectures (LA) specifying an implementation neutral computation. The LA comprises computational specifications and related logical constraints (i.e., defined by logical assertions) that specify provisional loops and provisional partitionings of those loops. The LA contains virtually no programming language constructs. Synthetic partitioning constraints add implementation specific design patterns. They define how to find frameworks with desired design features, how to reorganize the LA to accommodate the frameworks, and how to map the computational payload from the LA into the frameworks. The advantage of synthetic partitioning constraints is they allow implementation neutral computations to be transformed into custom implementations that exploit the high capability features of arbitrary execution platform architectures such as multicore, vector, GPU, FPGA, virtual, API-based and others.
