SD-WAN Overlay Network Service and IoT Device Reachability Detection
Summary
USPTO published patent application US20260113256A1, filed October 21, 2024, covering techniques for detecting network service and Internet of Things device reachability via inline monitoring with in-band probes in an SD-WAN overlay fabric. The application includes seven inventors and is classified under CPC H04L 43/0811, H04L 12/4641, H04L 41/0654, and H04L 43/12. Multi-tenant edge devices at branch sites may transmit probes to network services at data centers and determine reachability based on probe responses.
About this source
USPTO classification H04L covers transmission of digital information: network protocols, modulation schemes, wireless signal processing, coding, encryption in transit, and multiplexing. With 5G, 6G, and satellite internet driving new filings, H04L is one of the largest active patent classes. Every newly published application in H04L lands in this feed, around 215 a month. Applications publish 18 months after filing, so this feed reveals what MediaTek, Qualcomm, Ericsson, Samsung, Huawei, and dozens of smaller companies were working on in the prior year and a half. Watch this if you compete in networking hardware, advise telecoms on IP strategy, or scout acquisition targets in wireless infrastructure.
What changed
USPTO published patent application US20260113256A1 for network service and IoT device detection in SD-WAN overlay fabrics. The application describes techniques enabling multi-tenant edge devices at branch sites to transmit probes to network services at data centers, with inline monitoring and reachability determination using in-band probes. This is a standard patent application publication — no enforcement, compliance obligation, or regulatory requirement is imposed. Affected parties include companies developing SD-WAN technology, network equipment manufacturers, and IoT connectivity solutions providers who may need to monitor this application as it progresses toward examination and potential grant.

Abstract
Techniques for detecting network service and Internet of Things (IoT) device reachability via inline monitoring with in-band probes in an SD-WAN overlay fabric are described. The techniques may include enabling, by a multi-tenant edge device at a branch site, a tenant onboard the multi-tenant edge device, to transmit a probe to a network service at a first data center. The multi-tenant edge device may determine, based at least in part on the probe, whether the network service is reachable. Based at least in part on determining that the network service is not reachable, the multi-tenant.
