Abstract: An object of the present disclosure is to provide a network system that prevents traffic of frames between networks while connecting the networks to each other via a plurality of boundary devices. The present disclosure is a network device set in a boundary of a first network and connected to a second network different from the first network, the network device discriminating that a frame flowing into the first network from the second network is a broadcast frame, an unknown unicast frame, or a multicast frame and, when a frame flowing out from the first network to the second network is a frame discriminated as the broadcast frame, the unknown unicast frame, or the multicast frame flowing into the first network from the second network, discarding the frame.

Abstract: The present disclosure enables a user device to connect to a network via a single edge device out of a plurality of existing edge devices without information being communicated between the edge devices and a device that branches signals and provides branched signals to a plurality of edge devices.

Abstract: A shared-nothing database system is provided in which parallelism and workload balancing are increased by assigning the rows of each table to “slices”, and storing multiple copies (“duplicas”) of each slice across the persistent storage of multiple nodes of the shared-nothing database system. When the data for a table is distributed among the nodes of a shared-nothing system in this manner, requests to read data from a particular row of the table may be handled by any node that stores a duplica of the slice to which the row is assigned. For each slice, a single duplica of the slice is designated as the “primary duplica”. All DML operations (e.g. inserts, deletes, updates, etc.) that target a particular row of the table are performed by the node that has the primary duplica of the slice to which the particular row is assigned. The changes made by the DML operations are then propagated from the primary duplica to the other duplicas (“secondary duplicas”) of the same slice.

Abstract: Techniques are provided to allow more sophisticated operations to be performed remotely by machines that are not fully functional. Operations that can be performed reliably by a machine that has experienced a hardware and/or software error are referred to herein as Remote Direct Memory Operations or “RDMOs”. Unlike RDMAs, which typically involve trivially simple operations such as the retrieval of a single value from the memory of a remote machine, RDMOs may be arbitrarily complex. The techniques described herein can help applications run without interruption when there are software faults or glitches on a remote system with which they interact.

Abstract: An object of the present invention is to provide an edge device, a control method, and a program with which the effects of loop generation can be minimized from the NW operator side while ensuring connection normality with the device of an NW user. An edge device according to the present invention physically closes an access port upon confirmation that the access port has been connected to an external device while the access port is in a physically released state and a DF state is undefined, notifies other edge devices within an EVPN MH configuration that the host device has entered a state in which the host device may become the DF and causes an EVPN function unit to calculate the DF state to be set, physically opens the access port when the calculation result indicates DF, and physically closes the access port when the calculation result indicates BDF.

Abstract: Distributed query processing is often performed by a set of nodes that apply MapReduce to a data set and materialize partial results to storage, which are then aggregated to produce the query result. However, this architecture requires a preconfigured set of database nodes; can only fulfill queries that utilize MapReduce processing; and may be slowed down by materializing partial results to storage. Instead, distributed query processing can be achieved by choosing a node for various portions of the query, and generating customized code for the node that only performs the query portion that is allocated to the node. The node executes the code to perform the query portion, and rather than materializing partial results to storage, streams intermediate query results to a next selected node in the distributed query. Nodes selection may be involve matching the details of the query portion with the characteristics and capabilities of the available nodes.

Abstract: A network device (PE), a network control method and program which can reduce a BUM traffic packet loss even when a time is taken for route recalculation according to a routing protocol due to a malfunction in a network infrastructure are provided. A network device according to the present invention requests each PE connected to the same ES as that of the network device to perform DF reelection on the basis of a redundant PE list from which the network device has been deleted when cease of a BGP session is detected. In addition, the PE requested to perform the DF reelection executes the DF reelection based on the redundant PE list from which the aforementioned PE has been deleted. In the present invention, BUM traffic can be immediately forwarded from a PE that has become a new DF even when a time is taken for route recalculation according to the routing protocol because another PE connected to the same ES is caused to serve as a DF when the BGP session is ceased.

Abstract: An object of the present disclosure is to provide a provider network device, a network system, and a program that shorten a communication disconnection time during redundancy switching in a Single-Active redundant configuration. The provider network device according to the present disclosure notifies a CE that a VLAN, which has been communicating with traffic, is disabled due to setting of a block point or that new traffic communication is enabled due to releasing of the block point. This allows the CE to quickly delete a previously used transfer database and build up a new transfer database, and thus it is possible to shorten a communication disconnection time during redundancy switching.
