摘要： A multicast tree is provided in an application multicast network. A child node in the multicast tree detects a degradation of quality of service associated with a service being received at the child node. The child node determines whether the degradation of quality of service is resulting from a child-parent link or an upstream link in the multicast tree.

摘要： In a method of semantic querying in a peer-to-peer network, an item of information is mapped into a semantic vector based on the latent semantic indexing algorithm or any IR algorithms that can derive a vector representation. The semantic vector is associated with an address index as a key pair. The key pair is stored in an overlay network formed from the peer-to-peer network such that the stored key pair is proximally located to at least one other key pair having a similar semantic vector.

摘要： A computer-implemented method for determining resources utilized by a service request in a data processing system. The method includes determining monitored relationship types from monitoring data, determining relationship domains, determining intra-domain relationships from relationships that are internal to the relationship domains and determining cross-domain relationships from the intra-domain relationships that are linked between pairs of the relationship domains, and determining resources utilized by the service request from the intra-domain and cross-domain relationships. The domains are derived from one of the relationship types that is monitored by a single monitoring application.

摘要： a virtual storage module operable to run in a virtual machine monitor may include a wait-queue operable to store incoming block-level data requests from one or more virtual machines. In-memory metadata may store information associated with data stored in local persistent storage that is local to a host computer hosting the virtual machines. The data stored in local persistent storage replicates a subset of data in one or more virtual disks provided to the virtual machines. The virtual disks are mapped to remote storage accessible via a network connecting the virtual machines and the remote storage. A cache handling logic may be operable to handle the block-level data requests by obtaining the information in the in-memory metadata and making I/O re-quests to the local persistent storage or the remote storage or combination of the local persistent storage and the remote storage to service the block-level data requests.

摘要： A decentralized process to ensure the dynamic placement of applications on servers under two types of simultaneous resource requirements, those that are dependent on the loads placed on the applications and those that are independent. The demand (load) for applications changes over time and the goal is to satisfy all the demand while changing the solution (assignment of applications to servers) as little as possible.
