Abstract: A system for bandwidth estimation includes an interface and a processor. The interface communicates with a fat-tree (FT) network including multiple switches including (i) leaf switches belonging to a bottom level, (ii) spine switches belonging to a top level and (iii) intermediate switches belonging to one or more intermediate levels. Links connect between selected ones of the switches. The processor is to calculate, for a given level of the FT network that is divided into multiple groups of switches, oversubscription ratios for the respective groups, an oversubscription ratio of a group being indicative of a ratio between (i) a first available bandwidth on the links connecting the switches in the group to a lower level, and (ii) a second available bandwidth on the links connecting the switches in the group to a higher level, and to report a figure of merit of the FT network based on the oversubscription ratios.

Abstract: A network adapter includes a port and one or more circuits. The port is to send packets to a network in accordance with a Remote Direct Memory Access over Converged Ethernet (RoCE) protocol. The one or more circuits are to decide whether a packet is permitted to undergo Adaptive Routing (AR) in being routed through the network, to mark the packet with an indication of whether the packet is permitted to undergo AR, and to send the marked packet to the network via the port.

Abstract: A method includes providing a plurality of processes interconnected by a network, each of the plurality of processes being configured to hold a block of data destined for others of the plurality of processes. A set of data for all-to-all data exchange is received from one or more of the processes. The set of data is configured as a plurality of blocks of data in a matrix as matrix data, the matrix being distributed among the plurality of processes. The matrix data is transposed by changing the position of selected blocks of data of the plurality of blocks of data relative to the other blocks of data of the plurality of the blocks of data, without changing the structure of each of the blocks of data. The transposed matrix data is over the network and is then received, repacked, and conveyed to destination processes.

Abstract: Systems, computer program products, and methods are described herein for network discovery, port identification, and/or identifying fiber link failures in an optical network, in accordance with an embodiment of the invention. The present invention may be configured to sequentially connect each port of an optical switch to a network port of a server and generate, based on information associated with network devices connected to the ports, a network map. The network map may identify which network devices are connected to which ports of the optical switch and may permit dynamic port mapping for network installation, upgrades, repairs, and/or the like. The present invention may also be configured to determine a fiber link in which a failure occurred and reconfigure the optical switch to allow communication between an optical time-domain reflectometer and the fiber link to test the fiber link.

Abstract: A method for communication includes provisioning each node in a network with a respective set of two or more network addresses. Each node in succession is assigned a respective network address from the respective provisioned set that has not been assigned for use by any preceding node. Upon finding for a given node that all the network addresses in the respective provisioned set were assigned to preceding nodes, the preceding nodes are searched to identify a candidate node having an additional network address in the respective provisioned set, other than the assigned respective network address, that was not yet assigned to any of the nodes. The additional network address is assigned to the candidate node instead of the respective network address that was previously assigned to the candidate node, and the assigning of the network addresses to the nodes in the succession resumes following the candidate node.

Abstract: A network adapter includes a host interface and circuitry. The host interface is configured to connect locally between the network adapter and a host via a bus. The circuitry is configured to receive from one or more source nodes, over a communication network to which the network adapter is coupled, multiple packets destined to the host, and temporarily store the received packets in a queue of the network adapter, to send the stored packets from the queue to the host over the bus, to monitor a performance attribute of the bus, and in response to detecting, based at least on the monitored performance attribute, an imminent overfilling state of the queue, send a congestion notification to at least one of the source nodes from which the received packets originated.

The coupler may include a first end and a second end configured to receive optical fibers and a top surface and bottomed surface defining a through hole extending between the top and bottom surfaces. The coupler may include a reflective surface that redirects the optical signals between a first direction and a second direction substantially perpendicular to the first direction. The coupler may position one or more optical fibers along a second direction such that an optical signal from the plurality of optoelectronic transceivers is directed into one or more optical fibers or an optical signal from the one or more optical fibers is directed into a plurality of the optoelectronic transceivers, with the coupler accommodating different diameters of optical fiber including POF, SMF, and/or MMF fiber.

Abstract: A method for communication includes transmitting data packets from a communication device to a network. Upon receiving in the communication device a congestion notification from the network, a rate of transmission of the data packets from the communication device to the network is reduced. While transmitting the data packets, after reducing the rate of transmission, the rate of transmission is increased incrementally when a predefined volume of data has been transmitted since having made a previous change in the rate of transmission.
