  • Patent number: 8755392
    Abstract: 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.

  • Patent number: 8359397
    Abstract: Embodiments of a system and method for establishing reliable connections between peers in a peer-to-peer networking environment. In one embodiment, a reliable communications channel may use transmit and receive windows, acknowledgement of received messages, and retransmission of messages not received to provide reliable delivery of messages between peers in the peer-to-peer environment. In one embodiment, each message may include a sequence number configured for use in maintaining ordering of received messages on a receiving peer. A communications channel may make multiple hops on a network, and different hops in the connection may use different underlying network protocols. Communications channels may also pass through one or more firewalls and/or one or more gateways on the network. A communications channel may also pass through one or more router (relay) peers on the network. The peers may adjust the sizes of the transmit and receive window based upon reliability of the connection.

  • Patent number: 8176189
    Abstract: 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.

  • Patent number: 7587581
    Abstract: A processor reduces wasted cycle time resulting from stalling and idling, and increases the proportion of execution time, by supporting and implementing both vertical multithreading and horizontal multithreading. Vertical multithreading permits overlapping or “hiding” of cache miss wait times. In vertical multithreading, multiple hardware threads share the same processor pipeline. A hardware thread is typically a process, a lightweight process, a native thread, or the like in an operating system that supports multithreading. Horizontal multithreading increases parallelism within the processor circuit structure, for example within a single integrated circuit die that makes up a single-chip processor. To further increase system parallelism in some processor embodiments, multiple processor cores are formed in a single die. Advances in on-chip multiprocessor horizontal threading are gained as processor core sizes are reduced through technological advancements.

  • Patent number: 7574523
    Abstract: 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.

  • Patent number: 7533172
    Abstract: 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.

  • Patent number: 7437534
    Abstract: A Very Long Instruction Word (VLIW) processor having a plurality of functional units includes a multi-ported register file that is divided into a plurality of separate register file segments, each of the register file segments being associated to one of the plurality of functional units. The register file segments are partitioned into local registers and global registers. The global registers are read and written by all functional units. The local registers are read and written only by a functional unit associated with a particular register file segment. The local registers and global registers are addressed using register addresses in an address space that is separately defined for a register file segment/functional unit pair. The global registers are addressed within a selected global register range using the same register addresses for the plurality of register file segment/functional unit pairs.

  • Patent number: 7401152
    Abstract: 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.

  • Patent number: 7401153
    Abstract: 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.

  • Patent number: 7340500
    Abstract: 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.

  • Patent number: 7316021
    Abstract: A processor includes logic for attaining a very fast exception handling functionality while executing non-threaded programs by invoking a multithreaded-type functionality in response to an exception condition. The processor, while operating in multithreaded conditions or while executing non-threaded programs, progresses through multiple machine states during execution. The very fast exception handling logic includes connection of an exception signal line to thread select logic, causing an exception signal to evoke a switch in thread and machine state. The switch in thread and machine state causes the processor to enter and to exit the exception handler immediately, without waiting to drain the pipeline or queues and without the inherent timing penalty of the operating system's software saving and restoring of registers.

  • Patent number: 7206841
    Abstract: 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.

  • Patent number: 7136927
    Abstract: A system and method for sending, resolving, and receiving queries for information on the status of network resources. A peer computing system may include one or more resolver nodes on a network for resolving queries for a resource to particular resource instances. The resolver nodes may receive query messages from peer nodes on the network. Each query message may request information about a resource implemented by one or more peer nodes on the network. The query messages may be formatted in accordance with a peer resolver protocol. The resolver node may determine a particular instance of the resource hosted on a particular peer node to receive the query. The resolver node may use a variety of criteria to determine a particular resource instance. The resolver node may forward the query message to the determined resource instance.

  • Patent number: 6801997
    Abstract: A processor includes logic for tagging a thread identifier (TID) for usage with processor blocks that are not stalled. Pertinent non-stalling blocks include caches, translation look-aside buffers (TLB), a load buffer asynchronous interface, an external memory management unit (MMU) interface, and others. A processor includes a cache that is segregated into a plurality of N cache parts. Cache segregation avoids interference, “pollution”, or “cross-talk” between threads. One technique for cache segregation utilizes logic for storing and communicating thread identification (TID) bits. The cache utilizes cache indexing logic. For example, the TID bits can be inserted at the most significant bits of the cache index.
