Abstract: A first machine identifies, from among a non-static collection of machines, a respective set of forward contacts that comprises a set of machines. The set of forward contacts are distributed along the ordered sequence in the forward direction away from the respective machine in an order of increasing similarity between the respective channel number assigned to the first machine and a respective channel number assigned to each of the set of forward contacts. The first machine establishes a respective direct communication channel between the first machine and each of the set of forward contacts. The first machine sends a first query to a first forward contact and sends collected answers for the first query to at least a second forward contact that has a greater similarity to the first machine based on the respective channel numbers of the first machine and the first and second forward contacts.

Abstract: A method is provided of managing a non-static collection of machines. A first client machine runs a first communication protocol. The non-static collection of machines includes a first linear communication orbit, the first linear communication orbit comprising a sequence of machines that run the first communication protocol, and a second linear communication orbit, the second linear communication orbit comprising a sequence of machines that run a second communication protocol distinct from the first communication protocol. The first client machine receives an instruction from a server to install the second communication protocol, installs the second communication protocol, and then submits a registration request to the server. The first client machine receives, from the server, contact information of a list of potential neighbors. The first client machine then, proactively constructs and maintains a respective local segment of the second linear communication orbit.

Abstract: Decoupling of a first machine from a plurality of machines in a network is disclosed. Each machine has a machine identifier. The plurality of machines are organized into a linearly ordered sequence in accordance with a predefined order of the machine identifiers. The first machine is configured to receive a query from a preceding machine and propagate the query to a succeeding machine in the linearly ordered sequence. Prior to decoupling from the network, the first machine informs respective presence of a first subset of machines to a second subset of machines that are not overlapping with the first subset of machines. The first subset of machines includes a machine having a lower machine identifier relative to the machine identifier of the first machine, and the second subset of machines includes a machine having a higher machine identifier relative to the machine identifier of the first machine.

Abstract: In a network of a plurality of machines and a server, the machines have self-organized into a linearly ordered sequence in accordance with a predefined order of their respective machine identifiers. The linearly ordered sequence includes one or more local segments each include a first machine followed by a sequence of second machines. A query regarding management information of a local segment is injected into the network at the first machine of the local segment. The query is forwarded along the local segment, and each machine in the local segment responds to the query by adding its own local information to any answers already accumulated in the payload of the query. A second machine in the local segment sends a report message containing aggregated management information that has been collected in the payload of the query to the server.

Abstract: In one aspect, machines in a managed network implements a set of rules that cause individual machines to directly interact with only a small number of machines in the network (i.e., a local neighborhood within the network), while the independent local actions of the individual machines collectively cause the individual machines to be self-organized into one or more communication orbits without any global control or coordination by a server or an administrator. The communication orbits are used for supporting network, security and system management communications in the managed network.

At a respective node of a non-static collection of nodes forming a linear communication orbit: the node identifies, from among the non-static collection of nodes, a set of forward contacts distributed in a forward direction along the linear communication orbit; the node monitors a propagation state of a first query that has departed from the respective node to travel in the forward direction along the linear communication orbit; and upon detecting a propagation failure of the first query based on the monitoring, the node sends the first query directly to a first forward contact among the set of forward contacts to initiate a failure recovery process within at least part of a segment of the linear communication orbit between the respective node and the first forward contact of the respective node.

The method includes, at a third machine between the second machine and the first machine in the linear communication orbit, conditionally storing the specific data in a local cache of the third machine according to a data caching method.

Abstract: A method of parallel processing by networked devices, in which distributed data in a network is accessed in parallel to provide results. Commands and queries by a user station define a set of such distributed data. The networked devices access the distributed data in portions, individually process each portion, conduct peer-to-peer communication to aggregate results from processing each portion, and individually determine whether and when to report results. Making effective use of network assets (such as processing and storage at each node), making effective use of concurrency of network assets, limiting bandwidth use between network assets and user stations, and limiting use of assets (such as processing and storage) at user stations.
