摘要:
Bulk information is transferred to nodes in a communication network having a plurality of widely dispersed nodes. The information can be an image, content, or configuration information. The information is uni-cast to a selection of nodes by a central node or server, to seed the information at certain nodes in the network. The information is then distributed by these seed nodes to every other node in the network. A first algorithm selects which nodes should be seeded with information by the central node. A second algorithm distributes information in the network on a query basis.

Systems and methods applicable, for example, in having a node inform its user of one or more events while the user interface of the node is in an idle state. The user might, for instance, be able to select one or more of the events of which she is informed for corresponding operations. The events of which the user is informed might include, for example, events corresponding to software operations and/or events corresponding to a network environment (e.g., a peer-to-peer environment).

A topology management process is implemented in peer-to-peer content distribution clouds using tracker nodes. Tracker nodes have information about available peers and assist peers in finding other peers to connect to. Various algorithms for use at the tracker nodes are described for selecting which peers to return as potentials for forming connections to. In addition, architectures and algorithms to allow efficient scaling of tracker nodes in peer-to-peer clouds are described.
摘要:
The present invention relates to a node for deployment on a peer to peer network. The node is programmed for monitoring the network to receive communication messages therefrom and to forward the communication messages, optionally changing the communications radius parameters to an optimal or near optimal value. The node can forward messages from one network to another or from one network to the same network. The invention also provides a method for monitoring communication messages for selected objects by nodes on a peer to peer network. The method includes interposing the node on the network. The node has at least one stored object corresponding to a communication message object stored at the node; and monitors the network to detect communication messages matching at least one of the stored objects and decides whether or not to forward or change communication message radius parameters based on some defined programming or configuration.
摘要:
A system and method for allowing peers to exchange messages with other peers independently of their network location in a peer-to-peer environment. Messages may be transparently routed, potentially traversing partitions (e.g. firewalls and NATs), and using different protocols to reach the destination peers. In one embodiment, any peer node may serve as a relay peer that allows peers inside a partition to have a presence outside the partition and provides a mechanism for peers outside partitions to discover and communicate with peers inside the partitions. In one embodiment, a relay peer may maintain information on routes to other peers and assist in relaying messages to other peers. In one embodiment, any peer may query a relay peer for route information. In one embodiment, messages may include routing information as part of their payloads.
摘要:
A system and method for providing advertisements in a peer-to-peer networking environment is described. In one embodiment, the peer-to-peer protocols may use advertisements to describe and publish the existence of peer resources. An advertisement may be defined as a structured, language neutral metadata structure that names, describes, and publishes the existence of a peer-to-peer platform resource, such as a peer, a peer group, a pipe, or a service. In one embodiment, user-defined advertisement subtypes (for example, using XML schemas) may be formed from these basic types. A peer in a peer-to-peer network may publish a resource advertisement to make the resource corresponding to the advertisement available to other peers on the network. Peers may discover published advertisements by broadcasting discovery query messages. Other peers may respond to discovery query messages by sending response messages that may include advertisements.
摘要:
System and method for providing multiple embodiments of abstract software modules in peer-to-peer network environments. A module class may have one or more module specifications. Each module specification may have one or more module implementations configured to execute within a particular execution environment. A unique module class identifier may be assigned to the module class. A role extension to the module class identifier may be generated for each instance of the module class that performs a different role in a context. A module specification advertisement may be generated for each module specification. A unique module specification identifier may be assigned to each module specification of the module class. A module implementation advertisement may be generated for each module implementation. In one embodiment, the module specification identifier of the corresponding module specification is included in each module implementation advertisement.
摘要:
A system and method for providing an open network computing platform designed for peer-to-peer computing. The peer-to-peer platform may provide protocols for peer-to-peer services and applications that allow peers to discover each other, communicate with each other, and cooperate with each other to form peer groups. The protocols may include a peer membership protocol, a peer discovery protocol, a peer resolver protocol, a peer information protocol, a pipe binding protocol, and a peer endpoint protocol. Services and applications that participate in the protocols may be provided to deal with higher-level concepts. Advertisements may be used to publish peer resources. The peer-to-peer platform provides the ability to replicate information toward end users and may enable peers to find content that is closest to them. The peer-to-peer protocols and unique peer identifiers may allow peer nodes to move to different locations and access services and other content independent of network physical addresses.
摘要:
A system and method for uniquely identifying peers and other resources in a peer-to-peer networking environment. In one embodiment, every peer in the peer-to-peer network may have a unique peer identifier. Other peer-to-peer network resources may also have unique identifiers, including peer groups, services, applications, pipes, endpoints, content and resource advertisements. Identifiers may serve to canonically refer to resources. Identifiers may be embedded in advertisements for resources. In one embodiment, a peer identifier may identify a peer group in which the peer is a member peer. In one embodiment, a peer may have a different peer identifier for each group in which it is a member peer. In one embodiment, an identifier may be bound to a network address of the resource. If the resource changes network addresses, the identifier may be bound to the new network address. Thus, identifiers provide dynamic addressing for resources in the peer-to-peer environment.
摘要:
A system and method for providing resources to networked devices for participating in a peer-to-peer environment. In one embodiment, a peer computing system on a network may include one or more bootstrap nodes that may provide, to devices coupled to the network, mechanisms for accessing resources for participating in the peer-to-peer environment. The bootstrap nodes may be peer nodes. The resources may give the devices access to services each of which may implement peer-to-peer platform protocols. The devices may be pre-configured to access one or more predefined peer nodes for information on bootstrap nodes. Alternatively, devices may use a bootstrapping mechanism to locate bootstrap nodes on the network.
