In one embodiment, a device in a network receives a set of known user identifiers used in the network. The device receives web traffic log data regarding web traffic in the network. The web traffic log data includes header information captured from the web traffic and a plurality of client addresses associated with the web traffic. The device detects a particular one of the set of known user identifiers in the header information captured from the web traffic associated with a particular one of the plurality of client addresses. The device makes an association between the particular detected user identifier and the particular client address.

Embodiments disclosed are directed to an immutable database with a bitemporal ledger for storing transactions in timelines for maintaining a record of all events and resources within the system. The bitemporal ledger may store a sequence of transactions which include a plurality of transactions previously received by the data processing system in a temporal sequence up to a current time. A new transaction is received and may be appended to the sequence of transactions based on temporal metadata associated with the transaction are received, The temporal metadata may include a valid-from time and a created-at time.

Embodiments disclosed are directed to implementing an immutable database. Several embodiments are directed to an architecture for implementing the immutable database as a data processing system with a real-time interface for buffering a plurality of transactions and a bitemporal ledger for storing the plurality of transactions and a processor. New transactions may be appended to the transaction to the plurality of transactions and processed in a temporal order which includes identifying a sequence of transactions in the bitemporal ledger associated with the transaction and incorporating the transaction into the sequence of transactions in the bitemporal ledger according to temporal metadata associated with the transaction to form an updated sequence of transactions.

Embodiments disclosed are directed to an immutable database in a data processing system for tracking a data state of the data processing system using multiple timelines or temporal sequences representing events occurring in the data processing system. The immutable database may maintain a current temporal sequence representing an existing data state of the data processing system and generate alternate temporal sequences representing an alternate data state of the data processing system. The alternate temporal sequence may be used to test retroactive events that are intended to replace or correct events that occurred in the current temporal sequence.

Embodiments disclosed are directed to ensuring resource compliance within a cloud-based environment. The embodiments include steps for performing both pre-provisioning and post-provisioning checks of resources, such as network protocols, prior to and after their deployment within the cloud-based environment. These steps include using bitemporal analysis to determine the impact of deploying resources within the environment through the use of multiple execution timelines where the impact of deploying a resource may be evaluated on an alternative timeline that does not change the current resource scope of the cloud-based environment. The analysis may further include tracking the impact of the resource after it has been deployed to ensure resource compliance.

Embodiments disclosed are directed to ensuring resource compliance within a cloud-based environment using a compliance system. The embodiments include steps for performing pre-provisioning checks of resources, such as network protocols, prior to their deployment within the cloud-based environment. The compliance system may include a number of components for performing the pre-provisioning check including a maintenance module, a collection module, and an evaluation module, which are used to evaluate the resource prior to deployment in the cloud-based environment.

A method of configuring at least one switch involves configuring the at least one switch to direct communication to at least one of a plurality of computers according to at least one outcome of simulated interaction of a plurality of virtual network routers. A method of simulating interaction of a plurality of virtual network routers involves: causing a first at least one processor circuit to simulate the interaction of the plurality of virtual network routers; and causing a second at least one processor circuit, different from the first at least one processor circuit, to simulate the interaction of the plurality of virtual network routers redundantly to the simulated interaction of the plurality of virtual network routers on the first at least one processor circuit. Apparatuses and computer-readable media are also disclosed.

A retimer device is provided that includes an elasticity buffer, a receiver, and a controller. The elasticity buffer adds or subtracts data in the elasticity buffer to compensate for different bit rates of two devices to be connected over a link, where the retimer is positioned between the two devices on the link. The receiver receives a data stream to be sent between the two devices on the link. The controller determines, from the data stream, a modification to one or more characteristics of the link, and causes size of the elasticity buffer to be changed from a first size to a second size based on the modification.

The present disclosure provides a method of processing data based on QUIC protocol stack, the method including: obtaining a connection identifier of a data packet; determining a server program used for processing the data packet, wherein the server program comprises a plurality of worker threads, wherein QUIC protocol stacks run in the plurality of worker threads; determining a corresponding worker thread from the multiple worker threads based on the connection identifier; and distributing the data packet to the corresponding worker thread to make the QUIC protocol stack on the corresponding worker thread process the data packet. The disclosure further provides a system, a computing device and a computer-readable storage medium of processing data based on QUIC protocol stack.
