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.

Abstract: A computerized method for directing transmission of a data packet within a distributed cloud computing system is disclosed that includes receiving the data packet by a receiving gateway instance deployed within the distributed cloud computing system, 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, when the session is not found via the session lookup, determining whether one least one peer firewall instance is available, and when a first peer firewall instance is available and the data packet is a synchronize packet, forwarding the data packet to the first peer firewall instance. In some instances, the data packet is a TCP packet and in others, the data packet is received from either of a spoke gateway or a transit gateway that is deployed within the distributed cloud computing system.

Abstract: Systems and methods are described herein generally relating to network security, and in particular, embodiments described generally relate to systems and methods for selecting microservices to process protocol data streams. For example, a method is disclosed, which calls for receiving a protocol packet, the protocol packet comprising a sequence number, generating a difference by subtracting a protocol message base from the sequence number, generating a first quotient by dividing the difference by a protocol common message length, generating a second value using the first quotient, determining a Transmission Control Protocol (TCP) reassembly resource using the generated second value, and transmitting the protocol packet to the determined TCP reassembly resource.

Abstract: Methods and apparatus for transferring packets in a packet switched communication system. A system is provided that includes an L2 device including a controller determining for each packet received whether the received packet is to be inspected, an inspection device operable to inspect and filter packets identified by the controller including using a zone specific policy and an L2 controller for transferring inspected packets in accordance with L2 header information using L2 protocols.

Abstract: A security device may be interconnected, via multiple links, between multiple network devices in a network. The firewall device may include multiple input interfaces that receive data units from a first network device destined for a second network device of the multiple network devices, identify a session associated with each of the data units, and process the data units in accordance with the identified sessions and a security policy.
