## 摘要

- **VMware×Cisco 开放网络互操作仍是本周最强虚拟化网络产品稿**：VCF Networking 以 VPC / Transit Gateway / Distributed TGW 对接 Cisco Nexus One，控制面用 **MP-BGP EVPN**，数据面 **VXLAN**，宣称减轻 edge node 运维与 VLAN/IP 变更摩擦（厂商博客，归档见下）。
- **Canonical SDN 概念博客仍在站**（2021 旧稿重抓）：解释控制面/数据面分离与 OpenFlow——对 MicroCloud 选型有背景价值，**不是 2026-09 新产品通稿**。
- **产业侧**：HPE 称与 Oracle OCI 扩展 Juniper PTX/MX/QFX 用于 RoCEv2 AI 后端；NextPlatform/NVSwitch 稿讨论 scale-up AI 网络——偏智算 fabric，不是 HCI 东西向默认路径。
- **本日无** 深信服 aNET / SmartX Everoute / ZStack ZNS / 华为网络新版本号通稿入归档高信号池。
- 规划含义：短线替换继续打 **模块化微隔离 + 标准 EVPN/VXLAN 互通**；智算节点单独列 GPU 后端网与 NIC mode，勿写成「HCI 开箱 DPU」。

## 原文摘录

### [VMware open networking × Cisco Nexus One](https://blogs.vmware.com/)

- 归档：`archive/2026-09-07/vmware/unlocking-agile-innovation-delivering-on-vmware-s-open-networking-appr-3ec29e10.txt`

> VMware announced an open, extensible networking ecosystem for VMware Cloud Foundation (VCF). … This blog recaps recent networking enhancements … and presents an overview of how the unified network fabric solution interoperates with Cisco Nexus One.
> Standards-based interoperability between VCF Networking and Cisco Nexus One simplifies the control plane … The VCF Networking Route Controller (RC) peers directly with the EVPN Gateway using the industry-standard MP-BGP EVPN protocol.
> In the data plane, end-to-end traffic flows are established over VXLAN encapsulation …

### [Canonical：What is SDN](https://ubuntu.com/blog/data-centre-networking-what-is-sdn)

- 日期：2021-10-08（站点 2026-09-07 仍挂）

> SDN is a network architecture model that adds a level of abstraction to the functions of network nodes … The decision-making part of the network device (control plane) is separated from its operational part (data plane) …

### HPE×Oracle RoCEv2（产业交叉）

- 归档：`industry/hpe-s-record-results-buoyed-by-rising-ai-tide-1d61758d.txt`

> The latest QFX switches will provide the high-density connectivity, dynamic load balancing, and advanced congestion management required for large RoCEv2 (RDMA over Converged Ethernet version 2) AI backend networks.
