Abstract: Un système dexploitation décentralisé amélioré dans un réseau de systèmes informatiques est décrit. Les systèmes dexploitation décentralisés existants comportent des limitations de performance de transmission imposées par leur incapacité à 1) traiter de manière fiable des défaillances de communication transitoires et des réinitialisations de nuds rapides, 2) fournir un protocole de transmission qui sadapte à la fiabilité des liaisons et 3) permettre lacheminement des transmissions par des combinaisons arbitraires de liaisons de communication. Les systèmes et les procédés décrits aux présentes résolvent ces problèmes en fournissant un protocole de session nud à nud fiable qui offre une livraison de messages à haute performance et une gestion et un soutien multi-interfaces. Cela est accompli par la transmission de toutes les données entre deux nuds du système dexploitation par une connexion unique pouvant exploiter dynamiquement de multiples interfaces entre les nuds.

Abstract: A method and apparatus for mirroring data between a plurality of sites is provided. At a first site of the plurality of sites, a record is maintained that identifies which changes made to one or more data blocks that are stored at the first site have had associated redo information replicated to the other sites of the plurality of sites. A priority value associated with a transaction that is to be performed at the first site is determined. The transaction specifies a modification to a data block. Thereafter, if the priority value indicates that the transaction should not be lost if the first site becomes inoperable, then the transaction is committed only after the record indicates that all other changes that have updated the data block at the first site have had their respective redo information replicated to the other sites of the plurality of sites.

Abstract: The present invention discloses a system and method for data communication. In the system and method for data communication, a part of communication peers in the communication system are assigned as super peers, and each super peer forwards message according to its route table. When a communication peer logs in the system, network information of the logged communication peer is saved in a super peer which is logically closest to the logged communication peer through messages forwarded among every super peer. And when an origination communication peer searches for a destination communication peer, the network information of the destination communication peer is saved in a super peer which is logically closest to the destination communication peer through the message forwarded among every super peer in super peer layer. The origination communication peer establishes connection with the destination communication peer based on the network information of the destination communication peer, and implements the data communication through the connection established.
