Examples are disclosed that relate to computing systems having a common conductive pathway. One example provides a computing system comprising a power supply configured to output electrical power for delivery to one or more power nodes, and one or more power monitors configured to identify a power overload condition based on the power output by the power supply. The computing system further comprises a parent controller configured to, based at least on receiving an indication of the power overload condition, transmit an instruction to one or more child controllers that causes each child controller to effect a change in an operational state of a corresponding power node. The computing system also comprises a conductive pathway along which electrical power output from the power supply is transmitted for delivery to the one or more power nodes, and along which the instruction is transmitted to the one or more child controllers.

In a network that includes a client, a server and one or more proxy entities that intercept network traffic between the client and the server, a computer-implemented method is provided including: establishing trust with a permissioned distributed database; computing hashes from packet payloads of network traffic originated, intercepted or received; storing the hashes to the permissioned distributed database so that the permissioned distributed database maintains hashes computed from packets of the network traffic originated, intercepted or received by the client, server and the one or more proxy entities; and validating the hashes by comparing, with each other, the hashes stored to the permissioned distributed database by the client, server and the one or more proxy entities to determine whether any packet payload of the network traffic was modified in transit.

In various implementations, a method of managing transactions in a distributed ledger is performed by a first network node that is configured to maintain a distributed ledger in coordination with a plurality of network nodes. In various implementations, the first network node includes a processor, a non-transitory memory, and a network interface. In various implementations, the method includes synchronizing a first clock of the first network node with respective clocks maintained by one or more of the plurality of network nodes. In various implementations, the method includes obtaining a transaction indicator including respective transaction data. For example, in some implementations, the method includes receiving a transaction request from a client device. In various implementations, the method includes synthesizing, by the first network node, a timestamp for the transaction based on the first clock. In some implementations, the timestamp indicates a time that associates the first network node to the transaction.

Transaction management in distributed ledger systems

Managing policies for a chain of administrative domains, from end-to-end, includes receiving, at a network device associated with an administrative domain that is part of a chain of administrative domains provisioning an Internet-based application or an Internet-based service to a network, a root block for a blockchain. The root block is generated by a network device in the network and includes a request for a specific network parameter over a specific time period. The network device associated with the administrative domain appends a first block to the blockchain including the root block to accept the request and configures the administrative domain in accordance with the specific network parameter when an end-to-end path in the chain of administrative domains accepts the request. The network device associated with the administrative domain also generates blockchain transactions that append network status updates to the blockchain during the specific time period.

In various implementations, a method of identifying anomalies is performed by a first network node that is configured to maintain a distributed ledger in coordination with a plurality of network nodes. In various implementations, the first network node includes one or more processors, a non-transitory memory, and one or more network interfaces. In various implementations, the method includes determining a characteristic value based on information associated with the distributed ledger. In some implementations, the distributed ledger stores blocks of transactions that were added to the distributed ledger based on a consensus determination between the plurality of network nodes. In various implementations, the method includes determining whether a current transaction satisfies the characteristic value. In various implementations, the method include indicating whether there is an anomaly based on a function of the current transaction in relation to the characteristic value.

In one embodiment, an apparatus includes a driver and a receiver. The driver has an output, wherein the output of the driver has an associated output termination. In addition, the receiver has an input, wherein the input of the receiver has an associated input termination. An interface between the output of the driver and the input of the receiver operates according to a set of one or more timing parameters, wherein the input termination, the output termination, and the set of timing parameters correspond to a bandwidth for data transfer or frequency for data transfer across the interface between the output of the driver and the input of the receiver.
