摘要： An input/output module (IOM) for use within a network storage system mounted within a rack enclosure. The IOM includes a switching component configured to provide top-of-rack (TOR) switching for data to be routed from input connectors to data storage devices within the rack enclosure. The IOM also includes a protocol interface configured to convert a protocol of the data from an input data protocol (e.g., Ethernet, Fibre Channel or InfiniBand™) to a protocol for use with the storage devices (e.g., nonvolatile memory express (NVMe) and Peripheral Component Interconnect Express (PCIe)). Among other features, the IOM allows switching to be dis-aggregated from a TOR switch and distributed throughout the data network of the rack.

摘要： A network adapter includes a network interface, a host interface and processing circuitry. The network interface connects to a communication network for communicating with remote targets. The host interface connects to a host that accesses a Multi-Channel Send Queue (MCSQ) storing Work Requests (WRs) originating from client processes running on the host. The processing circuitry is configured to retrieve WRs from the MCSQ and distribute the WRs among multiple Send Queues (SQs) accessible by the processing circuitry.

摘要： Methods, systems, and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by pre-processing, by a scheduling algorithm implemented by a Network Scheduling Tool (NST), VL information prior to initiating a scheduling procedure by, detecting VL information associated with VLs that having common physical resources that include a common direction of a switching port or an egress end system port; and storing the VL information associated with the set of VLs for retrieval by the NST to parse a VL list for scheduling to determine one or more conflicting VLs in functionalities with a VL that is to be scheduled by a first pass that attempts favoring scheduling a VL into a bin when previously scheduled VLs fail to exhibit conflicts; and a second pass that attempts to resolve at least one conflict exhibited in the scheduling procedure by offsetting a transmit time.

摘要： Some embodiments provide a method of providing distributed storage services to a host computer from a network interface card (NIC) of the host computer. At the NIC, the method accesses a set of one or more external storages operating outside of the host computer through a shared port of the NIC that is not only used to access the set of external storages but also for forwarding packets not related to an external storage. In some embodiments, the method accesses the external storage set by using a network fabric storage driver that employs a network fabric storage protocol to access the external storage set. The method presents the external storage as a local storage of the host computer to a set of programs executing on the host computer. In some embodiments, the method presents the local storage by using a storage emulation layer on the NIC to create a local storage construct that presents the set of external storages as a local storage of the host computer.

摘要： A computing platform executing an application may receive a response to a request for opening a network port for utilization by the application from a computing platform distinct from the computer platform executing the application. The computing platform executing the application may determine whether to open the network port for utilization by the application based on the response to the request. In some embodiments, the application may invoke at least one call to an application program interface (API) of an operating system (OS) running on the computing platform executing the application, and the request may be generated responsive to the at least one call to the API of the OS.

摘要： The disclosure provides for a system that includes a network controller. The network controller is configured to receive information from nodes of a network, where nodes include one node that is in motion relative to another node. The network controller is also configured to generate a table representing nodes, available storage at each node, and possible links in the network over a period of time based on the information, and determine a series of topologies of the network based on the table. Based on received client data including a data amount, the network controller is configured to determine flows for the topology. The network controller then is configured to generate a schedule of network configurations based on the flows, and send instructions to the nodes of the network for implementing the network configurations and transmitting client data.

摘要： A method supporting distributed resilient network interconnect (DRNI) in a link aggregation group at a network device is disclosed. The method starts with encapsulating a distributed relay control protocol data unit (DRCPDU) in a frame, wherein the DRCPDU includes a protocol data unit (PDU) structure. The PDU structure includes a type field indicating that the DRCPDU is for DRCP, a version field indicating a version number of the DRCP, and a set of type/length/values (TLVs) including: a terminator TLV indicating an end of the PDU structure, a portal information TLV indicating characteristics of the first portal, a portal configuration information TLV indicating configuration information of the first portal, a DRCP state TLV indicating variables associated with an intra-portal link (IPP), a home ports information TLV and a neighbor ports information TLV. The method continues with transmitting the frame encapsulating the DRCPDU from the network device to a neighbor network device.

摘要： Methods to strengthen the cyber-security and privacy in a proposed deterministic Internet of Things (IoT) network are described. The proposed deterministic IoT consists of a network of simple deterministic packet switches under the control of a low-complexity ‘Software Defined Networking’ (SDN) control-plane. The network can transport ‘Deterministic Traffic Flows’ (DTFs), where each DTF has a source node, a destination node, a fixed path through the network, and a deterministic or guaranteed rate of transmission. The SDN control-plane can configure millions of distinct interference-free ‘Deterministic Virtual Networks’ (DVNs) into the IoT, where each DVN is a collection of interference-free DTFs. The SDN control-plane can configure each deterministic packet switch to store several deterministic periodic schedules, defined for a scheduling-frame which comprises F time-slots. The schedules of a network determine which DTFs are authorized to transmit data over each fiber-optic link of the network. These schedules also ensure that each DTF will receive a deterministic rate of transmission through every switch it traverses, with full immunity to congestion, interference and Denial-of-Service (DoS) attacks. Any unauthorized transmissions by a cyber-attacker can also be detected quickly, since the schedules also identify unauthorized transmissions. Each source node and destination node of a DTF, and optionally each switch in the network, can have a low-complexity private-key encryption/decryption unit. The SDN control-plane can configure the source and destination nodes of a DTF, and optionally the switches in the network, to encrypt and decrypt the packets of a DTF using these low-complexity encryption/decryption units. To strengthen security and privacy and to lower the energy use, the private keys can be very large, for example several thousands of bits. The SDN control-plane can configure each DTF to achieve a desired level of security well beyond what is possible with existing schemes such as AES, by using very long keys. The encryption/decryption units also use a new serial permutation unit the very low hardware cost, which allows for exceptional security and very-high throughputs in FPGA hardware.

摘要： A method for handling of multicast data streams within a broadband access network of a telecommunications network includes: a specific service edge node receiving a join request message from or through a specific customer premises equipment; an activation request message being transmitted, by the specific service edge node, to a multicast controller node within the broadband access network; and the multicast controller node generating and/or replicating multicast data stream-related data packets and injecting these multicast data stream-related data packets, using a corresponding session identifier information, into a point-to-point-protocol connection or tunneling protocol connection between the specific service edge node and the specific customer premises equipment.
