A method for migrating a data schema comprising combining a first deterministic finite automaton with a second deterministic finite automaton to generate a modified deterministic finite automation. Identifying a state of the modified deterministic finite automaton without computed followers. Computing a new vector of original states for each state of the modified deterministic finite automaton corresponding to the identified state.

Apparatuses, systems, and techniques to eliminate redundant data packets. In at least one embodiment, a communication apparatus generates redundant data packets, and sends them in multiple packet streams. In at least one embodiment, a communication apparatus eliminates redundant data packets from received packet streams.

Embodiments of the present disclosure provide methods and devices for data transmission by a switch. The method can include transmitting, by the switch, over a first path, a first packet that is received from a first host to a second host; receiving a replacement packet from the first host, wherein the replacement packet is transmitted from the first host in response to a determination that the first packet was lost and wherein the replacement packet includes a path indicator; and based on the path indicator of the replacement packet, transmitting, over a second path different from the first path, at least part of the replacement packet to the second host.

A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the auxiliary Bluetooth circuit sniffs packets transmitted from the remote Bluetooth device and the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device. But the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the data type of packets transmitted from the remote Bluetooth device changes. In the period during which the auxiliary Bluetooth circuit operates at the relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit, and the auxiliary Bluetooth circuit does not sniff packets transmitted from the remote Bluetooth device.

An apparatus for interfacing with a circuit switched network may be configured to detect when a data carrier signal from a circuit switched network is offline. While the data carrier signal from the circuit switched network is offline, the apparatus may send, to a network element coupled with the circuit switched network via the apparatus, control packets indicating that the data carrier signal is offline. The apparatus may further maintain an active data carrier signal between the apparatus and the network device by sending, to the network element, protocol idle frames. The apparatus may buffer, at the apparatus, packets sent from the network element to the circuit switched network. Once the data carrier signal is restored, the apparatus may send, to the circuit switched network, control packets indicating that the data carrier signal is online and the packet buffered at the apparatus while the data carrier signal is offline.

Deadlocks in a multi-protocol heterogeneous packet-based transport system are avoided while maintaining real-time aspects. When receiving a plurality of packets from a root complex where contents of each packet from the plurality of packets organized in accordance with a first protocol, a sequence number is added to each packet and a packet type is identified. Every packet in the first plurality of packets is encapsulated into at least one packet organized in accordance with a second protocol to form a second plurality of packets organized in accordance with the second protocol. All the packets from the second plurality of packets are sent via a plurality of connections so that each connection from the plurality of connections only transports packets from the second plurality of packets that encapsulate packets from the first plurality that have a same packet type.

Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.
