摘要： A system and method are provided for ensuring delivery of a communication from one computer system or node to another. A first node includes an object handler, such as an ORB (Object Request Broker), that receives object references from higher-level services operating on the first node, wherein the referenced object resides on a second node. The first node's object handler generates a message to an object handler on the second node and attempts to send the message to the second node through a transport module. The message is assigned a unique identifier, such as a sequence number. If the first object handler receives an uncertain status concerning the message (e.g., other than a certain success or failure), it issues a query to the second node to determine if the message was received. If the query is received by the second object handler before the message itself is received, the message is considered lost or rescinded by the first node. The first node stores the identifier so that it will not be re-assigned to another message and the message is then re-sent with a different identifier. The second object handler notes the identifier and status of the rescinded message and will discard any message having that identifier that is received. The second node includes two or more data structures to track the status of communications sent from the first node. The first node, in addition to a collection of identifiers of lost messages, may also record the status of communications it attempts to send and may also note the identifiers of messages that could not be transmitted (e.g., because of communication link errors).

摘要： One embodiment of the present invention provides a system that facilitates communications between a cluster of nodes within a clustered computing system in a manner that tolerates failures of communication pathways between the nodes. The system operates by configuring a distinct logical pathway between each possible source node and each possible destination node in the cluster, so that each distinct logical pathway is routed across one of at least two disjoint physical pathways between each possible source node and each possible destination node. In doing so, the system configures a first logical pathway between a first node and a second node across a first physical pathway of at least two disjoint physical pathways between the first node and the second node. Upon detecting a failure of the first physical pathway, the system reroutes the first logical pathway across a second physical pathway from the at least two disjoint physical pathways between the first node and the second node. In one embodiment of the present invention, the system associates a distinct per-node logical address with each node in the cluster. For each source node, the system associates the per-node logical address of each possible destination node with a corresponding logical pathway to the destination node. In this way, a communication from a given source node to a per-node logical address of a given destination node is directed across the corresponding logical pathway to the given destination node.

摘要： The present invention discloses a method and an apparatus for recovering unicast traffic during an Ethernet ring failover, solves the problem of interruption of the unicast traffic during the Ethernet ring failover. In embodiments of the present invention, because a network switch sets the broadcast flags of the ports in the loop of the Ethernet ring to the set state before completion of flushing of the MAC address table, if the broadcast flag of the destination port corresponding to the destination address in a unicast packet received by the network switch is in the set state, the network switch broadcasts the unicast packet. Therefore, the network switch in the loop of the Ethernet ring can recover the interrupted unicast traffic without waiting for completion of flushing of the MAC address table, thereby implementing recovering the unicast traffic during an Ethernet ring failover.

摘要： Various embodiments provide a system, method, and computer program product for sorting and/or selectively retrieving a plurality of documents in response to a user query. More particularly, embodiments are provided that convert each document into a corresponding document language model and convert the user query into a corresponding query language model. The language models are used to define a vector space having dimensions corresponding to terms in the documents and in the user query. The language models are mapped in the vector space. Each of the documents is then ranked, wherein the ranking is based at least in part on a position of the mapped language models in the vector space, so as to determine a relative relevance of each of the plurality of documents to the user query.

摘要： The invention provides a system and method for determining the winner or winners of an on-line auction accepting proxy bids. Proxy bids are bids that do not have a bid price, but instead have ceiling price that indicates the highest price a bidder is willing to bid for goods. The system and method according to the invention are able to sort the bids from highest to lowest and determine a winner or winners depending on the amount of goods being offered for sale. The system then generates a winning bid price by determining the lowest bid required to win the auction. The winning bidder or bidders pay this winning bid price.

摘要： There is disclosed an improvement to a system, apparatus, method, and computer program product relating to a novel events-notification activity occurring within computer network environments including SAN, NAS and client server environments. A user at a convenient, single user-interface location in a network is enabled to establish such activity by creating and deploying template software objects which are configurable with respect to both events of interest and genre of notifications of such events. Accordingly, such user, operating at the user-interface at a client or head-end station and employing such templates, can select: (1) which particular network-failure events (from complete failures to measured degradations), such as those occurring in peripherals including disk array storage devices, are to be reported; (2) to whom such events shall be reported, worldwide; and, (3) the mode of communication by which such events shall be reported such as email, telephone, pager, etc. In those instances where certain databases in storage devices of servers employed throughout the network may contain templates which present name/content conflicts with client database templates the events-notification activity is less effective than it otherwise would be. There is disclosed a system, apparatus, method, and computer program product for handling such conflicts and thereby enhancing the effectiveness of the events-notification activity. An alternative embodiment of this solution handles the scenario where multiple networks having multiple clients sharing particular servers create template name/content conflicts.
