A Distributed Routing Table (DRT) mesh can comprise two or more nodes, each of which maintains its own routing table that represents some or all of the overall routing knowledge of the DRT mesh. Each node can be comprised of modular components that can perform various defined functions such that the features and abilities of the node can be customized by an application based on which modular components are instantiated. A routing table management module can maintain individual routing tables at each node, and can ensure that only entries that are close to the node, in a network topology sense, are maintained in the routing table. In addition, a security module can verify received messages based on an agreed-upon root certificate.

Distributed routing table architecture and design

Application programming interface (API) for starting and accessing distributed routing table (DRT) functionality. The API facilitates bootstrapping into the DRT by one or more devices of a group of devices (a mesh) seeking to collaborate over a serverless connection, establishing a node of the DRT, where each node is an instance of an application that is participating in the mesh, and node participation by allowing the application to search for keys published by other nodes in the mesh, or by becoming part of the mesh by publishing a key. The API facilitates optimization of the routing table for quickly finding a root of a specific key in the mesh by finding the key directly in a cache or by asking a root node of the key that is in the local routing table that is closest numerically to the key being searched.

Distributed routing table interface

A distributed hash table infrastructure is described that supports pluggable modules for various services. Transport providers, security providers, and other service providers may be swapped, providing flexibility in supporting various devices and networking configurations.

Application-configurable distributed hash table framework

An application program interface (API) for sending and receiving endpoint registration data and peer-to-peer network cloud data has a registration call for adding endpoint data to a peer-to-peer network. The API may receive explicit data regarding address information or may be instructed to select and maintain suitable address information as the topology of the peer-to-peer network changes. Blocking and non-blocking calls are exposed for retrieving information peer-to-peer network endpoint data.

Peer name resolution protocol simple application program interface

The claimed process and system provides a resolution process for a multi-level cache resolution protocol that involves a lookup procedure whereby the initiating node contacts each intermediate node directly using a communication link separate from any previous intermediate node. The resolution process may involve caching information from each contacted intermediate node during the resolution process to request leads on the target node in the form of a list of closer nodes known to the intermediary node.

Flower-petal resolutions for PNRP

In a distributed computing system, an artificial intelligence system may be employed to configure the network variables. A metric describing the overall system performance may be derived during network operation or simulation and compared to an ideal metric describing the same distributed system performance. The difference between the derived metric and the ideal metric may then be used with an artificial intelligence system to modify the network variables to evolve the system toward the ideal performance standard.

Self-evolving distributed system performance using a system health index

The overall health of a peer-to-peer network may be inferred from statistics gathered and analyzed pertaining to individual node and node-to-node performance within the peer-to-peer network. When used with simulations for development or testing, the health statistic may be used instead of or to supplement standard regression testing to determine whether or not changes made improve system performance. When used with live peer-to-peer networks, the health statistic may provide a real-time view into network performance. Such a view may be used to adjust peer-to-peer network topology or to isolate underperforming or malicious nodes.

System and method for monitoring and reacting to peer-to-peer network metrics

A computer implemented method and system enable users to share files in a server-less shared space. By providing access to such spaces via a visual presentation, the system renders content available for access by other group members. Access is sometimes provided through propagation of metadata or other uniquely identifying indicia associated with the shared space to all group members.

An extensible data structure for messages in a peer to peer name resolution protocol is presented. This message data structure utilizes a number of fields, each containing a message element. Preferably, the first field is the message header that includes protocol information and identifies the type of message. Each message element contains a number of fields. These message element fields include a type field, a length field, and the content or payload of the message element. In one embodiment, at least ten messages are formed for proper operation of a Peer To Peer Name Resolution Protocol (PNRP), including RESOLVE, RESPONSE, SOLICIT, ADVERTISE, REQUEST, FLOOD, INQUIRE, AUTHORITY, ACK, and REPAIR messages.
