20080289004 | Method and Module for Protecting Against Attacks in a High-Speed Network - A method, module and computer program for protecting a target against attacks in a high-speed network. The method according to the invention comprises the steps of generating a question, after having received a request from an initiator identified by a sourceID associated to a certain node in the network, sending the question to the node identified by the sourceID, in case that an answer to the question is received, evaluating the answer, and in case that a proper answer has been received, enabling communication between the initiator and the target by sending a further message from the target to the initiator. | 11-20-2008 |
20090024714 | Method And Computer System For Providing Remote Direct Memory Access - A method for providing remote direct memory access (RDMA) between two computers, preferably between central processing units (CPUs) and a functional subsystem of a computer system as part of their network communication, e.g. using TCP/IP. Tasks of analyzing network protocol data and the actual RDMA operations can be offloaded to the functional subsystem with this method. Further, the functional subsystem cannot compromise the status of the first computer system as only access to certain allowed memory locations is granted by a memory protection unit during phases of actual data transfer between the functional subsystem and the CPUs. | 01-22-2009 |
20100217905 | Synchronization Optimized Queuing System - A synchronization optimized queuing method and device to minimize software/hardware interaction in network interface hardware during an end-of-initiative process, including network adapter queue implementations for network interface hardware for optimized communication in a computer system. An end-of-initiative procedure to ensure that the network interface hardware has received an interrupt enable and to recheck the interrupt queue is unnecessary in the present invention. | 08-26-2010 |
20110299394 | Translating Between An Ethernet Protocol And A Converged Enhanced Ethernet Protocol - Translating between an Ethernet protocol used by a first network component and a Converged Enhanced Ethernet (CEE) protocol used by a second network component, the first and second components coupled through a CEE Converter that translates by: for data flow from the first network component to the second network component: receiving, by the CEE converter, traffic flow definition parameters for a single CEE protocol data flow; calculating, by a credit manager, available buffer space in an outbound frame buffer of the CEE converter for the data flow; communicating, by the credit manager to a CEE credit driver of the first component, the calculated size of the buffer space together with a start sequence number and a flow identifier; and responding, by the CEE credit driver to the CEE converter, with Ethernet frames comprising a private header that includes the flow identifier and a sequence number. | 12-08-2011 |
20110302481 | Translation Between A First Communication Protocol And A Second Communication Protocol - Translating between a first communication protocol used by a first network component and a second communication protocol used by a second network, where translating includes: receiving, by a network engine adapter operating independently from the first and second network components, data packets from the first and second network components; and performing, by the network engine, a combined communication protocol based on the first communication protocol and the second communication protocol, including manipulating data packets of at least one of the first communication protocol or the second communication protocol, thereby offloading performance requirements for the combined communication protocol from the first and second network components. | 12-08-2011 |
20110320759 | MULTIPLE ADDRESS SPACES PER ADAPTER - A plurality of address spaces are assigned to an adapter. To select a particular address space for the adapter, a requestor identifier and address space identifier provided in a request by the adapter are used. Each address space may have a different address translation mechanism associated therewith. | 12-29-2011 |
20120230334 | MESSAGE FORWARDING TOWARD A SOURCE END NODE IN A CONVERGED NETWORK ENVIRONMENT - A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address. | 09-13-2012 |
20120230340 | MESSAGE FORWARDING TOWARD A SOURCE END NODE IN A CONVERGED NETWORK ENVIRONMENT - A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address. | 09-13-2012 |
20140092912 | FIBRE CHANNEL OVER ETHERNET SWITCH IMPLICIT LOGOUT - A process for an implicit logout of links to a fibre channel over Ethernet switch includes receiving, at a second switch, a first message from a first switch. The first message indicates an implicit link logout event on one of two or more links between the first switch and a node. Also, the process includes transmitting a second message from the second switch. The second message indicates zoning information for all of the two or more links between the first switch and the node. | 04-03-2014 |
20150023364 | MECHANISM FOR TERMINATING RELAY OPERATIONS IN A DISTRIBUTED SWITCH WITH CASCADED CONFIGURATION - Provided are a method, a system, and a computer program product in which a plurality of switches are maintained in a cascaded configuration. A switch relays a switch fabric internal link services (SW-ILS) to generate a pair of exchanges comprising a first exchange and a second exchange at the switch. In response to a termination of the first exchange of the pair of exchanges, the second exchange of the pair of exchanges is terminated. | 01-22-2015 |
