Abstract: A flow identifier is described for packet sequences through a secure tunnel of an SD-WAN in a tunnel-less mode. A method includes receiving a sequence of packets from a first client at the first hub, the sequence of packets each having a same flow, facilitating a secure tunnel between the first hub and the second hub, assigning a flow identifier to the sequence of packets, converting fields from a header of the packet to a metadata supplement to the packet to form a reduced packet, encapsulating the reduced packet in a wrapper that includes the flow identifier, and sending the packet of the sequence of packets from the first hub to the second hub the secure tunnel.

Abstract: Embodiments herein disclose path selection for data traffic within a software-defined wide area network using traffic metrics. Some embodiments relate to a method that includes polling peers of the SD-WAN for traffic metrics, receiving traffic metrics from at least a portion of the peers, combining the received traffic metrics, calculating performance of a plurality of possible paths from a source node to a destination node, the nodes being within the SD-WAN topology, and selecting a path from the source node to the destination node based on the calculated performance.

Abstract: Embodiments of methods and systems for managing traffic across a WAN are disclosed. A method for managing traffic across a WAN involves identifying incoming traffic as Direct Internet Access (DIA) traffic at a first node, identifying incoming traffic as SD-WAN traffic at the first node, policing the DIA traffic at the first node, and adapting the policing of the DIA traffic at the first node in response to a comparison between the SD-WAN traffic and an SD-WAN traffic threshold.

Abstract: End-to-end data packet flow control is described for an overlay environment of a wide area network. A method includes detecting an active session of a specific application with a source node and a destination node within an overlay environment, detecting a traffic flow from the source node to the destination node associated with the active session, mapping the traffic flow to a dedicated service processing thread of a network services appliance, mapping an identifier to the dedicated service processing thread, and forwarding the traffic flow to the destination node through the dedicated service processing thread by applying the identifier to the traffic flow.

Abstract: Methods and system for providing network connectivity are disclosed. In an embodiment, a method for providing network connectivity involves receiving from a Mobile Network Operator (MNO) an access ID and an IP address at a SASE domain, wherein the access ID and the IP address correspond to a wireless device, generating an IP address-to-tenant mapping at the SASE domain by applying the access ID and the IP address to an access ID-to-tenant mapping, and forwarding traffic received at the SASE domain from the wireless device via the MNO according to the IP address-to-tenant mapping.

Abstract: Method and systems for transitioning a wireless device between client-less connectivity and client-based connectivity are disclosed. In an embodiment, a method for transitioning a wireless device between client-less connectivity and client-based connectivity involves forwarding traffic from a wireless device through a SASE domain, receiving a request for information related to a SASE gateway in the SASE domain from the wireless device, transmitting information related to the SASE gateway from the SASE domain to the wireless device in response to the request, and transitioning the wireless device between client-less connectivity to the SASE gateway and client-based connectivity to the SASE gateway.

Abstract: Embodiments herein disclose conditioning traffic through multiple data paths of a Software-Defined Wide Area Network (SD-WAN). Some embodiments include monitoring a first and a second path through an SD-WAN to reach a destination node, comparing the link utilization for the first and the second path to generate an allocation ratio of the first and the second path, allocating a sequence of data packets to the first and the second path using the allocation ratio to generate a first path data sequence and a second path data sequence, generating a forward error correction (FEC) packet for first path sequence, sending the first path data sequence to the destination node on the first path, sending the second path data sequence to the destination node on the second path, and sending the FEC packet on at least one of the first and the second path.

Abstract: Embodiments herein disclose methods for selecting one or more paths for routing application traffic based on application performance metrics for hosted applications. In an embodiment, to select the best path, the available paths can be monitored to understand the performance of specific applications through those paths. Subsequently, the performance data is used to derive an application link score (ALS) for any given combination of application and path. The ALS is then be used to determine the best path for a given application.

Abstract: A method for shaping traffic across a wide area network is disclosed. The method involves advertising a data rate limit across a wide area network (WAN) from a first node, measuring the rate of data received at a WAN interface of the first node, and, if the measured rate of data received at the WAN interface of the first node exceeds a maximum threshold, advertising a reduced data rate limit across the WAN, and, if the measured rate of data received at the WAN interface of the first node is below a minimum threshold, advertising an increased data rate limit across the WAN.

Abstract: A method involves setting a link aggregation control protocol (LACP) link state for all links in a first service node to STANDBY to put at least one multiplexer in the first service node in a WAITING state to disable frame collection at the redundant service node and setting the LACP link state for all links in a second service node to SELECTED to put at least one multiplexer in the second service node in a COLLECTING/DISTRIBUTING state to enable frame collection at the primary service node.
