Data transmission method and system, and a non-transitory computer-readable storage medium
A method for data transmission includes: if correctly receiving one or more source data packets, a destination node selecting source data packets which have not been saved from the source data packets to save; if receiving one or more network coded data packets, the destination node decoding them, and if the decoding can be correctly conducted and source data packets can be obtained, the destination node selecting source data packets which have not been saved from obtained source data packets to save; if judging that the number of currently saved source data packets is greater than one, the destination node selecting and sending one saved source data to other destination nodes, or after conducting network coding according to part or all of saved source data packets to obtain one or more network coded data packets, the destination node selecting and sending one network coded data packet to other destination nodes.
INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING SYSTEM
An information processing apparatus includes, in an aspect, a communication port, a reading unit, a determination unit, a collecting unit, and a sending unit. When a communication cable is connected to the communication port, the reading unit reads a failure condition table and a collection item table from a storage unit provided in a communication cable. The determination unit determines whether the state of communication via the communication cable connected to the communication port satisfies the condition in the failure condition table. When the determination unit determines that the state of the communication via the communication cable connected to the communication port satisfies the condition, the collecting unit collects the information corresponding to the item in the collection item table. The sending unit sends the information collected by the collecting unit to a predetermined device.
Methods and apparatus related to virtualization of data center resources
In one embodiment, an apparatus includes a switch core that has a multi-stage switch fabric. A first set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have a protocol. Each peripheral processing device from the first set of peripheral processing devices is a storage node that has virtualized resources. The virtualized resources of the first set of peripheral processing devices collectively define a virtual storage resource interconnected by the switch core. A second set of peripheral processing devices coupled to the multi-stage switch fabric by a set of connections that have the protocol. Each peripheral processing device from the first set of peripheral processing devices is a compute node that has virtualized resources. The virtualized resources of the second set of peripheral processing devices collectively define a virtual compute resource interconnected by the switch core.
Name services for virtual cluster switching
One embodiment of the present invention provides a switch that facilitates name services in a virtual cluster switch. The switch includes a name service database indicating at least one media access control (MAC) address learned at a second switch. The switch also includes a control mechanism. During operation, the control mechanism distributes information on a locally learned MAC address to the second switch. In addition, the control mechanism receives information on a MAC address learned at the second switch.
Distributed method of data acquisition in an AFDX network
The subject matter disclosed herein relates to a frame switch of an AFDX network in which the data acquisition application is decentralized. When the switch has to acquire the data transmitted on a virtual link, the switching table contains, apart from the input port and the output port (s) taken by this link, an ID representing the MAC address of the switch. The frames of this link are then not only switched but also transmitted to the network interface of the switch and processed by a dedicated application (DDA), hosted inside the switch. This application can be interrogated by a remote server and transfer the data that it has stored locally.
Network function virtualization for a network device
An apparatus for performing network function virtualization (NFV), comprising: a memory, a processor coupled to the memory, wherein the memory includes instructions that when executed by the processor cause the apparatus to perform the following: receive an instruction to virtualize a network device within a network, divide, according to the instruction, the network device into a plurality of network functions (NFs) used to form a virtualized network node that corresponds to the network device, launch the NFs within one or more virtual containers, and group the virtual containers together using a group identifier (ID) that corresponds to the virtualized network node, wherein each of the NFs correspond to a network function performed by the network device prior to virtualization.
Shading and Lighting Control Using a Control Network
A control system is disclosed that includes a room controller transmitting signals to both a shade control network and a light control network, directing that motorized roller shades and dimmable lights be set to desired intensity levels. The control system further includes an intelligent hub that provides a trickle-charge re-charge current via power-over-Ethernet cables to batteries associated with each of the motorized roller shades for re-charging the batteries, thereby eliminating power supplies being installed within walls. The intelligent hub provides for communication with the room controller based on streaming protocol and with the shade control network based on event-based protocol. A computer running user-interface software can be connected to the system to facilitate programming.
CUSTOMER PREMISES EQUIPMENT (CPE) WITH DEVICE SLICING
A customer premise equipment (CPE) associated with a customer premise forms a virtual machine (VM) and allocates a portion of processing resources and a portion of communications resources included in the CPE to the VM. The processing resources include, for example, general purposes processes and specialized processors for performing certain tasks. The communications resources relate to exchanging data with the CPE. The VM is assigned to a service provider, and service data associated with a service is received from the service provider. The service data to be processed by the VM and the processed service data is forwarded to user devices at the customer premise to provide the service to the user devices. The CPE may form different VMs for different service providers.
Virtual PCIe Based Ethernet Controller for In-band Communication Between Server and BMC
Serial communication between a baseboard management controller and a host server may be reprogrammed for Ethernet communications. A PCIe high-speed bus, for example, may be reprogrammed as an Ethernet controller. Network addresses may then be shared for Ethernet communications between the baseboard management controller and a motherboard of the host server. Ethernet communications thus allow software applications operating in the host server to access resources associated with the baseboard management controller without relying on the Intelligent Platform Management Interface (IPMI) specification, which may be incompatible with some protocols and/or services.
Enhanced hierarchical virtual private local area network service (VPLS) system and method for ethernet-tree (E-tree) services
A network apparatus comprising a trunk end point associated with an Ethernet-tree (E-Tree) service in a network domain and configured to forward a frame that comprises a tag according to the tag in the frame, wherein the tag in the frame is a root tag that indicates a root source of the frame or a leaf tag that indicates a leaf source of the frame, and wherein the trunk end point is coupled to a second end point associated with the E-tree service outside the network domain.
