The Short Version
Huawei, the Chinese technology company, showed European customers an upgraded line of networking equipment in Florence this week.
Its main pitch: the cables and switching boxes that link the chips training artificial intelligence often leave those chips waiting in traffic. Huawei says its new design keeps 98% of the connections busy, makes the computing more than 7% faster, and needs 30% less equipment.
It is also selling security built into the hardware, at a time when European buyers are rethinking how much they rely on Chinese suppliers. The performance figures are Huawei’s own.
Huawei unveiled an upgraded Stellar Intelligent Network portfolio for Europe at the Huawei Network Summit 2026 Europe in Florence on October 17, 2026, issuing the announcement in Italian, Dutch, Turkish, Slovak and Russian. The update covers three product lines: Stellar Intelligent Fabric for data center networks, Stellar Intelligent WAN for links between sites, and Stellar Intelligent Campus Network for offices and branches. It also adds new eKit networking products for small and mid-sized businesses.
Huawei said its self-developed “100T” switches enable a two-tier, multi-plane data center architecture that quadruples network capacity while using 30% fewer switches and optical modules, and that its Network Packet Load Balancing (NPLB) algorithm lifts link utilization to 98% and AI training and inference performance by more than 7%. The same week, Huawei pressed the same AI-era networking message in Vienna. It announced a network-security partnership with Macau operator CTM at Network X 2026. At UBBF 2026 on October 13, it highlighted large-scale commercial use of its NG WAN solution, where data communication product line vice president John Cai called AI the decisive opportunity for networks.
Executive Summary
The Stellar upgrade is a broad enterprise networking refresh, but its most consequential claim concerns AI data centers. Huawei is arguing that the network connecting AI accelerators is not passive plumbing. In its account, the network determines how much useful work expensive compute actually does, and a better-balanced fabric recovers performance that would otherwise be lost to congestion.
The second thread is security. Nearly every product line in the upgrade carries a built-in security feature: an intrusion-detection card, an integrated quantum key distribution card, post-quantum cryptography across wired and wireless links, and threat detection running directly on switches. Huawei is presenting security as a property of the hardware rather than an add-on. That is a pointed choice in a European market where buyers have been reassessing their exposure to Chinese network suppliers.
For buyers, the announcement is a set of specific, testable numbers rather than vague promises. However, none of the figures comes with a stated baseline, cluster size or independent benchmark. The useful response is to treat them as a procurement checklist, not a conclusion.
The Network as a Compute Multiplier
The headline claim rests on a mechanism that AI cluster operators know well. Large training jobs split work across many GPUs or other accelerators, which must constantly exchange intermediate results in lockstep. When those exchanges hit a congested link, every chip in the job waits for the slowest transfer. Conventional data center load balancing assigns whole traffic flows to paths, typically by hashing. That approach can pile several large flows onto the same link while neighbouring links sit underused. Huawei’s NPLB algorithm, as its name indicates, balances at the level of individual packets, spreading traffic across all available paths. Huawei says this drives network-wide link utilization to 98% and raises training and inference performance by more than 7%.
If that figure holds in a customer’s environment, the economics are straightforward. A 7% throughput gain on a fixed cluster is roughly equivalent to adding 7% more compute without buying more accelerators, power or floor space. Accelerators are the dominant cost in an AI cluster, so recovered utilization is worth far more than the network’s own price tag. That is the commercial logic Huawei is selling: spend on the fabric to get more out of the chips.
The claim needs context before it can be priced. Huawei has not said what the 7% is measured against, on which models, at what cluster scale, or with which accelerators and network adapters. Packet-level spraying also typically requires endpoints that can handle packets arriving out of order, so the gain may depend on the rest of the stack. Operators should treat 98% and 7% as hypotheses to reproduce on their own workloads.
Fewer Tiers, Fewer Optics
The fabric’s other claim targets hardware count. Huawei says its self-developed 100T switches support a two-tier, multi-plane architecture that quadruples network capacity while cutting the number of switches and optical modules by 30%. In industry usage, the 100T label denotes switching capacity on the order of 100 terabits per second per device. Higher-capacity switches let a network reach the same number of servers with fewer layers.
That matters because optical modules — the transceivers that convert electrical signals to light at each end of a fibre link — are a large and growing share of AI network cost and power. Every extra tier between servers adds more links, more transceivers and more hops. A flatter design reduces all three, which is why Huawei frames the 30% reduction as a total cost of ownership saving. The affected parties are clear: cluster builders weighing capex, and optics suppliers whose unit volumes shrink when topologies flatten.
As with the performance claim, the comparison point is unstated. Quadrupled capacity and 30% fewer components relative to which previous design, at what scale, are the numbers a network architect would need. Huawei describes a three-level energy-saving framework covering devices, network and operations aimed at European environmental and carbon requirements, but it attached no energy figures to it.
Security Built Into the Box, Sold Into a Cautious Market
Security runs through every line of the upgrade. On the WAN side, Huawei cites an intrinsic security card that it says detects and blocks intrusions in real time with over 95% precision. It also cites what it calls the first integrated quantum key distribution (QKD) card, which uses quantum physics to exchange encryption keys and which Huawei says cuts deployment cost by more than 60%, plus APN6-based isolation of sensitive data. On campus networks, Huawei offers post-quantum cryptography (PQC), meaning encryption designed to resist future quantum computers, across wired and wireless connections. It also says local inference on switches cuts threat-detection time from 5 minutes to under 10 seconds, and that more than 20 inline algorithms in branch gateways detect 95% of unknown threats. For distributed AI, Huawei says layered model partitioning keeps raw data on premises.
Embedding security in network hardware has real operational appeal. It can mean fewer separate appliances, fewer integration points and faster response at the edge. It also concentrates trust in a single supplier. For any vendor, European buyers increasingly ask who can verify the security functions, which cryptographic standards they implement, and whether independent certification is available. That question carries particular weight for Huawei, given the scrutiny Chinese network suppliers have faced in Europe. Huawei’s Vienna announcements point the same way: the CTM partnership is framed around strengthening network security in the AI era. The company is making security its lead argument rather than a defensive footnote.
WAN and Campus Claims Aimed at the Budget Line
Beyond the data center, the claims target recurring costs. Huawei says its lossless Starnet algorithm delivers more than 95% cross-region compute efficiency and cuts dedicated line costs by 60%, an argument aimed at enterprises running AI workloads across distant sites. On campus networks, it claims an 84% reduction in wireless interference, double the industry-average performance, a 30%-plus cut in total cost of ownership for 10 Gbps campus networks via multi-GE switches and flexible Right-to-Use licensing, and mean time to repair under 5 minutes.
The small-business lineup is more concrete. It comprises Aura10/AR580 converged gateways with antivirus and intrusion prevention, S630 10GE core switches that can manage up to 1,000 access points for hotels, and AP362H access points with 1.6x antenna gain for retail. These are product specifications rather than benchmark claims, and they show Huawei pushing the same security-first message down-market. Its NG WAN commercial momentum, presented at UBBF 2026, suggests the WAN story is being sold to operators and enterprises alike.
Background
Huawei is a Chinese technology company that supplies telecom operator equipment and enterprise networking gear. Stellar Intelligent Network is its umbrella for enterprise networking, spanning the data center fabric that links servers and AI accelerators, the wide-area networks that connect distant sites, and the campus networks inside offices, hotels and shops.
AI data centers have made networking a first-order design problem. Training large models requires thousands of chips to exchange data constantly, so congestion, hardware count and optical transceiver costs now weigh on cluster economics alongside the chips themselves. Huawei presented the Stellar upgrade at its Florence summit days after related Vienna events, Network X 2026 and UBBF 2026, where it framed AI as the defining opportunity for network vendors and operators.
