A computer implemented method, apparatus, and computer usable program code for processing data packets. A set of data fragments are received at the data processing system to form a set of received data fragments. Assembly of the set of data fragments is initiated into a data packet, and a determination as to whether the data packet is an incomplete data packet. Responsive to a determination that the data packet is an incomplete data packet, the incomplete data packet is filled with at least one character to form a final data packet. The final data packet is forwarded to the target.

A method of propagating data packets in a network of nodes is disclosed. The method, implemented at one of the nodes, includes: generating at least one data packet of a first type; collecting a set of data packets of the first type during a first time period, the set including the at least one generated data packet and at least one data packet of the first type received from one or more first nodes in the network; and for each data packet in the set: randomly select two or more neighbouring nodes connected to said one of the nodes; transmit, to each of the two or more selected neighbouring nodes: the data packet, wherein the two or more selected neighbouring nodes are configured to relay the data packet to one or more second nodes in the network using a mode of data propagation that is arbitrarily selected for that neighbouring node. The invention is particularly suited for implementation on a blockchain network such as, for example, the Bitcoin blockchain.

An example operation may include one or more of connecting, by a sparse peer, to a blockchain network of a plurality of peers controlled by orderers, configuring the sparse peer to operate with a partial state of a chain to reduce a bootstrap time of the sparse peer, specifying, by the sparse peer, data selection filters based on the partial state of the chain, receiving, by the sparse peer, blocks that match the selection filters from the plurality of the peers via a gossip, storing, by the sparse peer, the blocks in a ledger of the sparse peer, determining, by the sparse peer, if the ledger of the sparse peer is up-to-date based on the partial state of the chain, and in response to the determination that the ledger of the sparse peer is up-to-date, bootstrapping the sparse peer.

Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized content fabric. Some implementations are associated with a network configured to manage content object parts representing digital content. A content object part includes raw data, metadata, and build instructions. The network includes: a data layer storing the raw data and the metadata of the content object parts, a code layer storing the build instructions of the content object parts, a contract layer storing a digital contract associated with the content object parts, and a ledger configured to record one or more transactions. Digital output can be provided by at least processing the build instructions and the digital contract in relation to the raw data and the metadata.

Public and private hybrid distributed cloud storage system and cloud storage method including an application system, a segmentation aggregation system, a public storage system and a private storage system. The application system provides original complete data and initiates an access request to the segmentation aggregation system. The segmentation aggregation system divides original complete data into data fragments and distributes to said public storage system and private storage system according to a preset storage proportion and receives the fragments returned by the public and private storage systems and aggregates them into the complete data, and transfers to said application system. The public storage system manages, authenticates and stores fragments. The private system manages, authenticates, counts, controls and stores fragments. The method, based on the cloud storage system, includes logging data and reading data. This invention solves problems of limited capacity private storage systems, inadequate bandwidth and security vulnerable public storage system.

Provided is a storage system capable of avoiding the increase in communication between nodes in the coordination of the file service and the block service. This is a storage system in which a plurality of nodes, which provide a file service for performing I/O in file units and a block service for performing I/O in block units, are connected via a network, and the storage system comprises a management unit which manages the first file processing unit and the second file processing unit as a pair, sets the first file processing unit to be operable, manages the first block processing unit and the second block processing unit as a pair, and sets the first block processing unit to be operable.

The invention provides methods of encoding content for distribution over a network and methods for decoding encoded content which has been distributed over the network. In a first example in which the content is divided into a plurality of segments and each segment comprising a plurality of blocks of data, the method comprises selecting a segment from the plurality of segments and selecting at least two blocks of the selected segment from a store of blocks. A new encoded block is created from a linear combination of the selected blocks.

A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers.

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or “core” is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. According to an aspect of this disclosure, the CDN edge network is then used to deliver receipts associated with transactions that are processed into the blockchain.

An example operation may include one or more of hosting a first virtual node in a blockchain-as-a-service (Baas) provider, hosting a second virtual node in the Baas provider, and controlling transmission of information between the first virtual node and the second virtual node along an internal signal path of the Baas provider, wherein the information corresponds to a block in a blockchain that includes an entry for the first and second virtual nodes.
