A system, comprising: a configurable parser that comprises one or more configurable parsing engines, wherein the configurable parser is arranged to receive a packet and to extract from the packet headers associated with a set of protocols that comprises at least one protocol; a packet type detection unit that is arranged to determine a type of the packet in response to the set of protocols; and a configurable data integrity unit that comprises a configuration unit and at least one configurable data integrity engine; wherein the configuration unit is arranged to configure the at least one configurable data integrity engine according to the set of protocols; and wherein the at least one configurable data integrity engine is arranged to perform data integrity processing of the packet to provide at least one data integrity result

A system is presented to efficiently communication data between a sub-network and a third-party application system, such that the third-party application system is able to perform one or more functions based on data sourced from the sub-network. A process scheduler system is presented to provide multiple communication paths to populate a data store of the third-party application system.

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.

Methods, systems, and computer-readable mediums configure electronic messaging applications to communicate with a server storing messages to and/or from an electronic messaging account of a user. A method involves receiving an electronic message address and a password of the user as inputs, deriving server connection settings based on the electronic message address, and applying the server connection settings to the electronic messaging account. Another method involves receiving an electronic message address of the user and discovering the server connection settings for the electronic messaging account on a server having a designated protocol name as a server prefix name to assist in locating the server and having the server connection settings. The method also involves retrieving the server connection settings from a file provided by the server in response to locating the server having the designated name and applying the server connection settings to the electronic messaging account.

A data intake and query system collects performance data from client devices and host devices and stores the performance data in one or more indexes. The system is further configured to facilitate correlation of the performance data collected from the client devices and the separate performance data collected from the host devices. For example, based on a determination that one or more identifiers stored in a portion of performance data received from client devices match one or more identifiers stored in a portion of the performance data received from host devices, a data intake and query may determine that the data portions are related. The portions of performance data, for example, may correspond to events the data intake and query system derives from the performance data collected from both client devices and host devices.

One embodiment provides a system that facilitates querying of historical network information. During operation, the system generates a query for historical information associated with interest and content object packets, wherein a name for an interest is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level, wherein the query is based on a name prefix that includes one or more contiguous name components. The system transmits the query to a responding entity. In response to receiving the historical information from the responding entity, the system performs an operation that increases network efficiency based on the historical information, thereby facilitating a protocol for querying the historical information to increase network efficiency.

Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing. The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols.

A data packet comprises a header and a payload. At least one digital signal processor is used to configure the payload to transport at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment. A service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. At least one digital signal processor is used to configure a single field in the header consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. At least one digital signal processor is used to form the data packet including the configured header and the configured payload. A transmitter transmits the data packet.

In an embodiment, a computer implemented method comprises receiving, at an edge node in a data communications network, a plurality of digital data packets that have been received via a wireless data interface, wired data interface or data path; filtering, by the edge node, the plurality of digital data packets to produce filtered digital data packets; in the edge node, executing code for a data communications protocol in which one or more of the filtered digital data packets causes the code to transition to different states of the protocol; in the edge node, in parallel with executing the code, executing a protocol state machine comprising a plurality of states and a plurality of transitions between the states to simulate correct execution of a particular data communication protocol; detecting, by the edge node, an anomaly between a first particular state of the protocol during the execution of the code and a second particular state of the protocol state machine, and in response, generating an anomaly event comprising digital data indicating that an anomaly event has occurred; in response to detecting the anomaly event, transmitting, by the edge node, an anomaly event log based on the anomaly event and the filtered digital data packets to a different computing device.

Certain aspects of the present disclosure relate to methods and apparatus for providing UDP receive offloading using the communications systems. For example, a method generally includes grouping, into a container, the datasets from the same source and destination arriving at a receiver based on datasets metadata, and ungrouping the datasets from the container once network layer processing on the container is completed and datasets are ready to traverse to a next destination.
