    IPC: H04L61/4511

    Abstract: A DNS server comprises: a receiver configured to receive a registration request comprising a domain name, a local address, and a scope, the registration request requests registration of the domain name; a processor coupled to the receiver and configured to execute computer instructions that cause the processor to: assign an address to the domain name based on the local address and the scope, and generate a registration response comprising the address; and a transmitter coupled to the processor and configured to transmit the registration response towards an endpoint. The processor may be further configured to cache a correspondence among the domain name, the address, and the scope.

    CPC classification number: H04L69/164 ,  H04L65/60

    Abstract: A method of establishing streams within a QUIC connection implemented by a first network device, comprising: transmitting a first open message through the QUIC connection to a second network device, the first open message identifying a protocol; receiving a second open message through the QUIC connection from the second network device in response to transmitting the first open message, the second open message identifying the protocol; and establishing a first stream between the first network device and the second network device within the QUIC connection for the protocol identified in the first open message and in the second open message.

    Abstract: A Self-Describing Packet block (SDPB) is defined that allows concurrent processing of various fixed headers in a packet block defined to take advantage of multiple cores in a networking node forwarding path architecture. SPDB allows concurrent processing of various pieces of header data, metadata, and conditional commands carried in the same data packet by checking a serialization flag set upon creation of the data packet, without needing to serialize the processing or even parsing of the packet. When one or h more commands in one or more sub-blocks may be processed concurrently, the one or more commands are distributed to multiple processing resources for processing the commands in parallel. This architecture allows multiple unique functionalities each with their own separate outcome (execution of commands, doing service chaining, performing telemetry, allows virtualization and path steering) to be performed concurrently with simplified packet architecture without incurring additional encapsulation overhead.
