摘要： A highly predicable quality shared distributed memory process is achieved using less than predicable public and private internet protocol networks as the means for communications within the processing interconnect. An adaptive private network (APN) service provides the ability for the distributed memory process to communicate data via an APN conduit service, to use high throughput paths by bandwidth allocation to higher quality paths avoiding lower quality paths, to deliver reliability via fast retransmissions on single packet loss detection, to deliver reliability and timely communication through redundancy transmissions via duplicate transmissions on high a best path and on a most independent path from the best path, to lower latency via high resolution clock synchronized path monitoring and high latency path avoidance, to monitor packet loss and provide loss prone path avoidance, and to avoid congestion by use of high resolution clock synchronized enabled congestion monitoring and avoidance.

摘要： Embodiments include an overlay multicast network. The overlay multicast network may provide a set of features to ensure reliable and timely arrival of multicast data. The embodiments include a congestion control system that may prioritize designated layers of data within a data stream over other layers of the same data stream. Each data stream transmitted over the network may be given an equal share of the bandwidth. Addressing in routing tables maintained by routers may utilize summarized addressing based on the difference in location of the router and destination address. Summarization levels may be adjusted to minimize travel distances for packets in the network. Data from high priority data stream layers may also be retransmitted upon request from a destination machine to ensure reliable delivery of data.

摘要： Some embodiments provide a method for a host computer that executes a set of data compute nodes (DCNs), for identifying a designated router for a multicast group. The method receives a membership request message to join the multicast group from a particular DCN of the set of DCNs, the membership request message including an address associated with the multicast group. The method identifies a logical router gateway from a set of logical router gateways as the designated router for the multicast group, based at least in part on the address associated with the multicast group, where different logical router gateways from the set of logical router gateways are assigned as designated routers for different multicast groups with different associated addresses. The method forwards the membership request message to the identified logical router gateway.

摘要： Examples of network bandwidth management are provided. A system may access, time series distribution data including a distribution of data points corresponding to an average count of network packets. Further, the system may determine, from the time series distribution data, trend data component, seasonal data component, cyclical data component, and irregular data component. Furthermore, the system may compute, baseline distribution traffic data based on the trend data component, the cyclical data component, and the seasonal data component. Furthermore, the system may identify auto regression data component and moving average data component based on the irregular data component. The system may further, determine an estimated network traffic for a future time interval based on the baseline distribution traffic data, a lagged covariate factor, and covariate metrics. Furthermore, the system may provide the estimated bandwidth based on the estimated network traffic to configure the server.

摘要： The present technology relates to an information processing device and an information processing method, in which streaming traffic can be subjected to a load dispersion by using a broadcast network.
An information processing device processes a request of contents, to be transmitted from a plurality of receiving devices, and dynamically switches return through communication and return through broadcast, as a return path of a response with respect to the request, on the basis of first identification information for identifying a broadcast area capable of being received by the receiving device, and second identification information for identifying the contents, the first identification information and the second identification information being included in the request, and thus, streaming traffic can be subjected to a load dispersion. The present technology, for example, can be applied to a dedicated server (a switching server) provided on a server backend side.

摘要： Some embodiments of the invention provide a new networking data path framework that employs one or more dedicated kernel threads to process network traffic on a host computer executing multiple machines (such as virtual machines or containers). This new framework is referred to as an Enhanced Networking Stack (ENS) in this document. In some embodiments, the dedicated kernel threads execute on dedicated CPU cores (e.g., one kernel thread per CPU core) to proactively poll physical NICs (PNICs) of the host computer and virtual NICs (VNICs) of the machines (e.g., VMs), and to perform packet processing operations on packets received by the host and packets transmitted by the machines. In some embodiments, each PNIC or VNIC is associated with one dedicated kernel thread, in order to avoid synchronization issues between the kernel threads. In the discussion below, these kernel threads are referred to as fast-path packet processing threads or as logical cores, or Lcores, and the physical and virtual NICs that are polled by the Lcores are referred to as polled network devices. In some embodiments, one Lcore can process multiple polled network devices. This is beneficial because in some embodiments one CPU core is dedicated to each Lcore (i.e., because one Lcore monopolizes the entire computing power of one CPU core), and it would be wasteful to dedicate one Lcore to just one polled network device, which might be underutilized.

摘要： Described embodiments provide systems and methods for securing communications between services in a cluster using load balancing. A first proxy of a first node of a cluster of nodes can receive a request for a service from at least one pod of the first node. The service can include a plurality of pods. The plurality of pods can execute in the cluster of nodes including the first node. The first proxy can select, responsive to a load balancing determination, a pod of a second node of the cluster of nodes to receive the request. An encrypted connection can be established with a second proxy of the second node. The request can be forwarded to the selected pod via the encrypted connection to the second proxy. The request can be decrypted at the second proxy and forwarded at the pod of the second node.

The computer program steps comprises monitoring bandwidth usage rate at a first provider interface, determining if bandwidth usage rate at the provider interface exceeds a bandwidth usage rate limit; and rerouting Internet traffic from the provider interface having bandwidth that exceeds the bandwidth usage rate limit to a second provider interface having available bandwidth capacity.

摘要： Technologies for Ethernet gateway congestion management in HPC architectures include a high-performance computing (HPC) switch with an Ethernet gateway that is configured to receive an HPC packet from an HPC fabric via a virtual lane (VL) of the Ethernet gateway. The Ethernet gateway is further configured to determine whether the HPC packet corresponds to a backward error correction notification (BECN), identify one or more priority code points (PCPs) of the HPC packet corresponding to a BECN as a function of the VL on which the HPC packet was received, and generate an Ethernet priority-based flow control (PFC) frame that includes the one or more identified PCPs in a header of the Ethernet PFC frame. Additionally, the Ethernet gateway is configured to transmit the Ethernet PFC frame to an Ethernet fabric as a function of the one or more identified PCPs. Other embodiments are described herein.
