摘要： A method, programmed medium and system are provided for preventing the denial of file system access to a plurality of clients accessing a NFS server. In one example, an NFS server is configured to listen on a server port. The server runs a separate daemon which “watches” client requests as they are received at the NFS server. The server processing system tracks the number of times a client sends consecutive TCP zero-window packets in response to a data packet from the server. If the number of zero-window packets crosses a user-defined threshold, then a routine is called to stop responding to that client using a backoff algorithm. When the server reaches a point where the number of available threads or any other relevant resource dips below a user-defined threshold, the server process starts terminating connections to the clients starting from the ones with the oldest entry in the table.

摘要： An approach is presented for determining a value of a bridge of a first ontology schema (S1) with a second ontology schema (S2). A bridge of S1 with S2 is generated. A sub-schema S is extracted from the bridge of S1 with S2. A schema S′ is created from S by removing common concepts and relationships to the common concepts, and for each common concept to which first and second concepts have immediate links in S, by creating a new immediate link in S′ between the first and second concepts. An intrinsic value of S′ and a strength of a bridge of S1 with S are determined. Based on the intrinsic value of S′ and the strength of the bridge of S1 with S, the value of the bridge of S1 with S2 is determined.

摘要： A computer implemented method and computer program product for obtaining a secure route. A trusted host sets a node security association for a trusted host. The trusted host receives, at the trusted host, a client communication request directed to a destination host. The trusted host builds a secure route query comprising a trusted host address, a destination host address, and at least one security level, to form at least one secure route. The trusted host sends packets from the trusted host to the destination host based on the at least one secure route. The packets are responsive to the client communication request, and the packets each have a security label that matches the security level.

摘要： A method for detecting and reducing packet drops in a communications system may include receiving a first packet having a sequence number, determining if a second packet having a sequence number immediately preceding the sequence number of the first packet is lost, and/or determining if a third packet having a sequence number immediately preceding the sequence number of the second packet is lost. A counter may be incremented if the second and third packets are determined as lost. An amount of time required before detecting link activity after an end of a previous frame may be reduced if the counter violates the count threshold and the amount of time has not been previously reduced. A lower link speed may be negotiated if a current link speed is above a negotiable threshold and the amount of time required before detecting link activity has been previously reduced.

摘要： A service module that provides for discovery of one or more network interfaces connecting a prospective remote procedure call (RPC) client, facilitates the provision of RPC programs in a network including multi-horned systems. When a request for a network address to an RPC application providing an RPC program is received from the RPC client, the RPC bind daemon discovers from the module, using the client response address, over which interface(s) the client is accessible. The daemon then selects an address of a network path to the RPC application that the prospective client can access and returns the corresponding network address. The service module monitors the network stack for RPC get address requests and builds tables of client address entries with corresponding network interface identifiers. The entries are retired according to an aging policy.

摘要： File system errors are handled and computing systems are recovered by, responsive to receiving a page buffer request, initializing a sleep timer according to a detection interval value plus a hang resolution range value; responsive to the timer expiring, detecting that a process, thread, application program, daemon, or task is waiting on availability of the requested page buffer; and responsive to the detection, quarantining metadata associated with the requested page buffer, failing the page buffer request and releasing one or more locks on the requested page buffer. This process is then optionally repeated for additional processes, threads, application programs, daemons, tasks or combinations thereof which are waiting for availability of the requested page buffer, optionally randomizing the detection interval value in order to avoid an instantaneous recovery from the error.

摘要： A method, programmed medium and system are disclosed which provide for end-to-end QoS for a set of processes that comprise a workload over nfs. A set of processes that comprise a workload such as the processes of a WPAR, or an entire LPAR are given a class designation and assigned priority/limits. The data are then passed to the server which allocates resources based on the sum total of all the current classes and their priorities and/or limits. This requires re-engineering the nfs client code to be workload-aware and the nfs server code to accommodate the resource allocation and prioritization needs of the nfs clients.

摘要： A method, system, and computer program product for memory affinitization in a multithreaded environment are provided in the illustrative embodiments. A first affinity domain formed in a computer receives from a second thread executing in a second affinity domain a request to access a unit of memory in the first affinity domain. The computer determines whether to migrate the unit of memory to the second affinity domain. The computer migrates, responsive the determining being affirmative, the unit of memory to the second affinity domain, thereby affinitizing the unit of memory with the second thread.
