EVPN All-Active Multihoming Load Balancing for PE Devices
Summary
USPTO published patent application US20260113275A1 on April 23, 2026, filed December 31, 2024 (Application No. 19006840), covering methods and systems for Provider Edge (PE) device preference in Ethernet VPN All-Active Multihoming. The invention allows network operators to configure an ingress PE to load-balance traffic across only a selected subset of egress PEs on a multihoming Ethernet Segment, with fallback to additional PEs when the preferred subset is unavailable. Inventors are Zhaohui Zhang, Soumyodeep Joarder, Vinod Kumar Nagaraj, and Vikram Nagarajan.
“Methods, devices, and systems to allow an operator to have the ingress PE load-balance to only a set of the PEs on the MHES are described.”
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 US20260113275A1, a new filing covering Ethernet VPN All-Active Multihoming Load Balancing for Provider Edge (PE) devices. The application describes methods allowing operators to restrict ingress PE load balancing to a configured subset of egress PEs on a multihoming Ethernet Segment, with automatic fallback to other available PEs if the preferred subset becomes unavailable.
Telecommunications equipment manufacturers and network equipment vendors developing EVPN-capable devices may wish to review the disclosed load-balancing preference mechanisms to assess potential overlap with existing or planned product features. Patent application publications do not grant enforceable rights; they signal an active filing in the IP landscape for networking and telecommunications technologies.

Provider Edge (PE) Device Preference in an EVPN All-Active Multihoming Ethernet Segment

Abstract
Ethernet VPN supports All-Active multihoming and an ingress Provider Edge (PE) can load balance traffic to all the egress PEs on a multihoming Ethernet Segment (MHES). Methods, devices, and systems to allow an operator to have the ingress PE load-balance to only a set of the PEs on the MHES are described. In the event that all PEs of the set are not usable (e.g., down, not attached to the ES, etc.), the ingress PE can load balance data traffic to one or more PEs on the MHES that are not in the set.
