    Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided. The memory management mechanism permits both buffered sending and receiving of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism permits grouping of DMA buffers that can be shared among specified connections based on any number of attributes. The memory management mechanism further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system in bulk, and expedited transfer of data to the host system.

    Abstract: A system and method for determining application dependent components includes capturing interactions of an application stored in memory of a first environment with other components at runtime. The interactions are parsed and categorized to determine dependency information. The application is migrated to a new environment using the dependency information to reconfigure the application after migration without application-specific knowledge.

    Abstract: A method monitors non-faulty application traces of a computer application with the runtime environment during fault-free activities to create non-faulty runtime signatures for the computer application. Once obtained, the method stores the non-faulty runtime signatures. The method then detects a faulty application trace of the computer application and compares the faulty application trace with the non-faulty runtime signatures by comparing a call graph of the faulty application trace with call graphs of non-faulty application traces of the application signatures to identify differences between the two (e.g., fault attributes). Then the invention outputs the fault attributes to allow the user to identify a fault cause.

    Abstract: A method of generating an annotated network topology of a network is described. The method includes; deriving a network topology by performing a route tracing utility between each pair of endpoints to determine the route taken by packets; initially annotating each network path with an initial value; determining the available bandwidth of a path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints; identifying a bottleneck link in the network path, and annotating all edges to generate an annotated network topology wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements.

    Abstract: One embodiment of the present method and apparatus for re-establishing anonymous data transfers between a first endpoint and a second endpoint in a network includes receiving, from a first node, the identity of a second node connected to the first node, where at least the first node is a neighbor node. A third node (a neighbor node) is then selected, and instructed to connect to the second node in order to establish a link for the path. In this manner, the first endpoint and the second endpoint remain unknown at least to each other (e.g., where “unknown” means that neither endpoint knows any identifying information, such as network address, about the other endpoint), and likely to all other nodes in the path as well. In another embodiment, a failure is detected at a neighbor node, where the neighbor node is part of an original path between the first endpoint and the second endpoint. The neighbor node's repair server is contacted for a repair node associated with the neighbor node, and a connection to the repair node is made such that the path is established in a manner that maintains anonymity of the first endpoint and the second endpoint relative to each other.
