摘要:
Embodiments of a shared resource distributed index mechanism that peers in a peer-to-peer network may utilize to distribute index entries corresponding to resources to indexes of shared resources among one or more other peers. These indexes may be used to direct queries to peers where the queries are most likely to be answered. When a query is received by a rendezvous peer including one or more indexes, contents of the query may be “looked up” in the index to find matches. The results of the lookup may include information on one or peer(s) that may hold advertisement(s) to the resource requested by the query. The query may then be forwarded to one or more peers that may hold the advertisement for the resource. Embodiments may provide “loosely-coupled” distribution of index entries for use in querying for resources in the peer-to-peer network.

A peer-to-peer platform that may provide mechanisms through which peers may discover each other, communicate with each other, and cooperate with each other to form peer groups is described. The peer-to-peer platform may comprise several layers including a peer-to-peer platform layer, a peer-to-peer services layer, and a peer-to-peer applications layer. At the highest abstraction level, the peer-to-peer platform may be viewed as a set of protocols. Each protocol may be defined by one or more messages exchanged among participants of the protocol. In one embodiment, the peer-to-peer platform may include, but is not limited to, one or more of a peer discovery protocol, a peer resolver protocol, a peer information protocol, a peer membership protocol, a pipe binding protocol, and an endpoint routing protocol. To underpin this set of protocols, the peer-to-peer platform may define a number of concepts including peer, peer group, advertisement, message, pipe, and endpoint.
摘要:
A system and method for providing peer groups in a peer-to-peer environment. A peer group may be one or more peers in a peer-to-peer environment that share a set of network services and content. A peer group may define an implicit scope for messages originating from members peers of the peer group. A peer group may provide redundant services and content for greater reliability. In one embodiment, interaction among peers and peer groups in the peer-to-peer environment may be implemented using protocols that are platform-independent as to programming language implementations and network transports. In one embodiment, peers may discover existing peer groups and join the existing peer groups. In one embodiment, peers may create new peer groups.

Embodiments of a decentralized mechanism for detecting the presence of entities in a peer-to-peer network. In one embodiment, using pipes, a peer may uniquely and independently generate an identity for a peer-to-peer network entity. The identity may be used to probe the peer-to-peer network for presence of instances of the corresponding entity on other peers regardless of which peer the identity was generated on and without using a central identity repository or presence system. In one embodiment, net crawling may be used to map identities and resolve the locations of instances of the corresponding entities. An entity may move anywhere on the network, and the decentralized mechanism for detecting entity presence may be used to locate the instance(s) of the entity.
摘要:
A system and method for establishing communications channels between and among peers in a peer-to-peer networking environment. Pipes may be used as communication channels for sending and receiving messages and other data between services or applications over input and output endpoints. Pipes may be asynchronous, unidirectional, stateless and unreliable. Bidirectional pipes may also be supported. Pipes may have ends that may be moved around and bound to different peers at different times. Point-to-point and propagate pipes may be supported. Pipes may connect peers that have a direct physical link and peers that do not have a direct link. Peers may communicate through pipes without knowing on which peer a pipe endpoint is bound. A message is sent to all peer endpoints currently connected (listening) to the pipe. The set of connected endpoints may be obtained from a pipe service using a pipe binding protocol.

System and method for multiplatform implementation of abstract software modules in peer-to-peer networking 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 unique module specification identifier may be assigned to each module specification of the module class. In one embodiment, a module specification advertisement may be generated for each module specification. 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.

A system and method for providing rendezvous nodes in a peer-to-peer networking environment is described. Rendezvous nodes preferably cache information about network resources that may be useful to peer nodes on a peer-to-peer network. In one embodiment, a network of rendezvous nodes may help peer nodes to discover network resources over long-range on the peer-to-peer network. Network resource may include, but may not be limited to peer nodes, peer groups, services, content, and communication channels. In one embodiment, rendezvous nodes may respond to discovery query messages from peer nodes. The discovery query messages may specify desired network resource information. In one embodiment, rendezvous nodes may provide route discovery for network resources. In one embodiment, a peer node may be pre-configured with a pre-defined set of rendezvous nodes to access on startup. These bootstrapping rendezvous may help the peer node discover network resources that it needs to start up.
