  • Publication number: 20240129232
    Abstract: A computerized method for directing transmission of a data packet within a distributed cloud computing system is disclosed. The computerized method includes operations of receiving, by a receiving gateway instance deployed within the distributed cloud computing system, the data packet, when a session corresponding to the data packet is found via a session lookup, forwarding the data packet to a destination in accordance with the session lookup, and when the session is not found via the session lookup, creating a tentative forward session and forwarding the data packet to a peer gateway instance. In some instances, the data packet is a User Datagram Protocol (UDP) packet. In some instances, the data packet is received from either of a spoke gateway instance or a transit gateway instance, and wherein the spoke gateway instance or the transit gateway instance is deployed within the distributed cloud computing system.

  • Patent number: 11956100
    Abstract: According to one embodiment, a network device may be adapted to operate within a virtual private cloud where network address translation (NAT) is performed through virtual machines and each network address translation is handled differently by a different NAT control logic unit. The network device features one or more hardware processors, and a memory that stores at least a plurality of network address translation (NAT) control logic unit and demultiplexer logic. The demuliplexer logic, when executed, receives an incoming message and, based at least in part on information within the incoming message, determines a selected NAT control logic unit to receive at least a portion of the information within the incoming message. The selected NAT control logic unit handles address translation for routing of a message based on the incoming message to a public network.
