A distributed gateway for controlling computer network data traffic dynamically reconfigures traffic assignments among multiple gateway machines for increased network availability. If one of the distributed gateway machines becomes unavailable, traffic assignments are moved among the multiple machines such that network availability is substantially unchanged. The machines of the distributed gateway form a cluster and communicate with each other using a Group Membership protocol word such that automatic, dynamic traffic assignment reconfiguration occurs in response to machines being added and deleted from the cluster, with no loss in functionality for the gateway overall, in a process that is transparent to network users, thereby providing a distributed gateway functionality that is scalable. Operation of the distributed gateway remains consistent as machines are added and deleted from the cluster. A scalable, distributed, highly available, load balancing network gateway is thereby provided, having multiple machines that function as a front server layer between the network and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers.

A scalable distributed wireless control and monitoring system for managing utility supply over a wide geographical area. Such distributed networks can manage/control electricity, gas, water and other petroleum product supply to a large geographical area. The network consist of plurality of nodes that control and monitor utility usage at subscriber point; these nodes are called activityNode. The ActivityNodes can communicate with one or plurality of superNodes. The superNodes act as center for control and management for the activityNodes. The superNode can send “instruction to disconnect” a subscriber to an ActivityNode. A superNode can exchange data with one or plurality of neighboring superNodes. An aggregate of superNodes can poll data from plurality of activityNodes on the network, this information can be analyzed to determine the network performance and can also be use to preempt fault on any part of the network.

The invention relates to the technical field of network communications, in particular to a cluster communication system and method for improving message transfer performances. The system comprises a message release end, a message server cluster containing a plurality of message servers, a message subscribing end and a distributed coordination service cluster. The cluster communication system and method for improving message transfer performances have a global single point-free clustering expandable distributed design; if one or more nodes of the message release end or subscribing end have a fault, other nodes in the same group can continue to send or receive messages, and a processing flow of the messages is not interrupted; by adopting an index-based distributed file storage solution, the defects of the existing DB and file storage are effectively avoided, so that the read and write efficiency of the messages is higher; and by using a long poll PULL message transfer manner, the throughput is ensured while the message instantaneity is ensured.

A system and method for providing an Application Programming Interface (API) that allows users to write complex graphics and visualization applications with little knowledge of how to parallelize or distribute the application across a graphics cluster. The interface enables users to develop an application program using a common programming paradigm (e.g., scene graph) in a manner that accommodates handling parallel rendering tasks and rendering environments. The visualization applications written by developers take better advantage of the aggregate resources of a cluster. The programming model provided by APT function calls handles scene-graph(s) data in a manner such that the scene and data management are decoupled from the rendering, compositing, and display. As a result, the system and method is not beholden to one particular graphics rendering API (e.g. OpenGL, Direct X, etc.) and provides the ability to switch between these APIs even during runtime.

A computer-implemented method and a distributed file system in a distributed data network in which file metadata related to data files is distributed. A unique and non-reusable mode number is assigned to each data file that belongs to the data files and a directory of that data file. A key-value store built up in rows is created for the distributed file metadata. Each of the rows has a composite row key and a row value (key-value pair) where the composite row key for each data file includes the mode number and a name of the data file. When present in the directory, the data file is treated differently depending on size. For data files below the maximum file size the entire file or portion thereof is encoded in the corresponding row value of the key-value pair. Data files above maximum file size are stored in large-scale storage.

A system for performance testing of scalability implementations and testing of stability in blockchain database implementations. The testing system comprises a cluster of private blockchain nodes instantiated on a network and a control console that allows the user to set the number of nodes in the network and the number of clients for testing of a particular blockchain implementation. Performance metrics are established and tested. The test system allows for staged testing using generated databases, wallets, and accounts starting with simple 5-node networks, expanding to larger networks, then testing with decreased block validation times, continuing to testing using alternative, faster trust schemes, then testing implementation on divided blockchains, and finally testing on shared blockchains.

An eventing method and system is provided that enables resource-constrained CE devices, at home, away from home, on-the-go, or behind a firewall, to communicate through asynchronous events with each other and/or with other type electronic devices, at home or on the Internet. Further, a scalable distributed system is provided that supports asynchronous eventing over the Internet efficiently and at low cost.

Systems and methods are provided for managing user information comprising presence information, wherein authentication of requesting parties is based on public-private key pair encryption and key Domain Name Service (kDNS) infrastructure. Thus, a response to a request for presence information may be dependent on the authentication status of the requesting party. Presence information stored on a presence server or other network element may be stored or updated upon receiving a request from a user which includes the requestors identify, and is signed with the private key of the requestor. After authentication of a user having a registered unique identifier and an associated public key, presence information may be stored or updated, in either encrypted or unencrypted form. Presence information is preferably stored with user specified policy information for managing access to the presence information by other users, e.g. what information may be shared with anonymous or unauthenticated other users, or with other specific authorized users, or authorized user groups. Advantageously, all communications between communication parties and network elements of the system are encrypted. A scalable and distributed system and method is provided for managing exchange of dynamic information, such as presence information, between users of communications and network services, with improved reliability, security, and personalization. Systems and methods are particularly applicable for securely managing exchange of presence information and other information for multiparty communications service and for peer-to-peer network services.

A fault tolerant system for a highly scalable distributed processing system in which fault tolerant groups (hereafter referred to as “FT groups”) are formed based on the functionalities of applications. A given FT group includes instances of the same applications and also different applications that perform the same function. The instances within the FT group are ranked as a primary and mirrors, which descend in rank. When the primary instance in the FT group crashes, that is, fails or becomes otherwise unavailable, the system utilizes the next ranking available (running) instance in the FT group as the primary instance. The change over to the next ranking mirror application is performed quickly and without loss of functionality through an exchange of “FT messages” under the control of a central monitoring and change-over control sub-system.
