Abstract: Described herein are systems and methods for a DAG based transaction processing system and method in a distributed ledger. In accordance with an embodiment, a DAG based transaction processing system and method in a distributed ledger can be introduced. The model can help achieve improved throughput performance. With additional weight mechanism, the final performance can be adjusted based on various business requirements. This is different from existing work that uses linear structure and can achieve better performance.

Abstract: Described herein are systems and methods for transaction identification (ID) generation in transaction-based environments. The systems and methods provided generated transaction IDs which inherently define a range of values (a range of blockchain heights) within which the transaction is valid. This obviates problems associated with traditional transaction ID databases where a transaction ID only comprises a hashed value. That is, the presently disclosed systems and methods are an improvement over traditional hashing schemes as in traditional hashing schemes, a server must traverse an entire transaction ID database to determine if an incoming transaction is valid.

Abstract: A tracker computer does not contribute content for inclusion in: a distributed ledger, a transaction, and a blockchain that records the transaction. In an embodiment that reduces network bandwidth needed by a blockchain network, the tracker computer receives, from first client computers, requests to track execution of transactions in a blockchain network that has multiple ledger computers and does not include the tracker computer. The tracker computer subscribes to the ledger computers for status notifications from the execution of the transactions. The tracker computer receives status notifications that indicate status of the transactions that occurred after the clients' subscribing for status notifications. The tracker computer records the status of the transactions. The tracker computer pushes the status of the transactions to the first client computers. From second client computers, the tracker computer receives pull requests for status of the transactions in the blockchain network.

Abstract: Described herein are systems and methods for a providing Ledger as a Service (LaaS). Blockchain technology helps bring potential solutions to the distributed ledger problem, with a linear record structure to record transaction history. However, there are different types of blockchain techniques (e.g., Hyperledger, Ethereum, Quorum), and users/developers need to know the explicit features of each technique and align with the required APIs. Ledger as a Service can allow users to an develop applications more efficiently, and can allow users to easily migrate applications among different blockchain techniques and platforms (e.g., between Hyperledger and Ethereum). LaaS can also allow for simplified transactions with a blockchain, and can additionally provide simplified communication between blockchains of different types.

Abstract: Techniques for realizing service chaining, a corresponding apparatus and an SDN (Software Defined Network) controller are disclosed. The method includes temporarily modifying an original destination MAC (media access control) address of a packet and an original source MAC address the packet during the time the packet makes a hop from one middlebox to another. A restore operation is used to restore the original source and destination MAC addresses after the hop is made.

Abstract: A method for processing a resource access request in a network based on a software defined network (SDN) protocol includes receiving a resource access request forwarded by a first SDN switch in the network, wherein there exists no forwarding rule matching the resource access request in the first SDN switch; obtaining, according to the resource access request, resource server information of a resource server where the requested resource is stored, wherein the resource server is located in the network; generating a forwarding rule corresponding to the resource access request according to the resource server information; and sending to the first SDN switch at least one portion of the forwarding rule corresponding to the resource access request, so that the first SDN switch forwards the resource access request according to the at least one portion of the forwarding rule.
