Milk-V Launches Milk-V Vega, the World's First RISC-V Open Source 10 Gigabit Ethernet Switch

August 22, 2023 -- Shenzhen MilkV Technology Co., Ltd (Milk-V) unveiled the world’s first RISC-V open-source 10-gigabit Ethernet switch - the Milk-V Vega. The core control chip utilizes the FSL1030M network switch chip developed by Wuhan Binary Semiconductor Corporation.

Milk-V Vega is a compact and high-density box-style open-source 10-gigabit Ethernet switch developed by Milk-V for the next-generation network architecture. It offers users a unified platform for various services such as broadband, voice, video, and surveillance, enabling comprehensive coverage of multi-service convergence. Equipped with domestically produced RISC-V high-reliability network switch chips, it significantly simplifies network architecture for enterprises and users, reducing energy consumption costs and operational expenses. It can be widely applied in scenarios including data centers, campuses, medium and large enterprise networks, hotels, research, and education.

Milk-V Vega supports comprehensive Layer 2 network protocol processing capabilities, including L2 bridging, L2 multicast, and storm suppression. It supports VLAN functions based on flows, ports, protocols, and subnets. It also includes STP, RSTP, and QinQ functionalities. Moreover, it provides features such as protection against DOS attacks, black and white lists, and protocol packet filtering. The device supports filters, link aggregation, OAM packet transmission, and port protection functions. It offers ACL capabilities for both inbound and outbound traffic, and also supports Ethernet synchronization and 1588 functions.

Simultaneously, as the world’s first RISC-V open-source 10-gigabit Ethernet switch, Milk-V Vega offers the following features to developers:

Built on an open-source Linux system, enabling easy secondary development and DIY.
Open access to openSBI, u-boot, and Linux kernel source code, along with a provided cross-compilation toolchain.
Equipped with a JTAG interface for convenient low-level development.
Furnished with RS232 and I2C interfaces, allowing for the connection of other sensors.
Supports standard 1U server racks, with the capability to install 2 Milk-V Vega units per rack layer.
Features dual 10-gigabit optical ports + 4 gigabit optical ports + 8 gigabit Ethernet ports, catering to homelab needs.
Supports remote configuration through WEB and SSH access.
Provides command-line business configuration for functions such as VLAN setup, port mirroring, MAC address learning, and traffic control.
Offers interface SDK and API for flexible implementation of business configurations.

The FSL91030M integrates 8 ports of gigabit Ethernet PHY, supporting 10/100/1000BASE-T and 100BASE-FX functionalities. It also incorporates 2 ports of 10G SerDes, enabling support for 1000BASE-X, SGMII, QSGMII, O-USGMII, and 10G BASE-R functionalities. Additionally, it includes 4 ports of 1G SerDes, capable of supporting 1000BASE-X and SGMII functionalities. The combination of 4 ports of 1G SerDes and 4 ports of gigabit Ethernet PHY can be configured as 4 Combo ports. The FSL91030M further supports 2 ports of RGMII/GMII/MII interfaces, serving as expandable management interfaces.

The FSL91030M is built upon Nuclei System Technology Co., Ltd.'s UX608 uCore architecture. It supports the RV32/64 IMACFDPB instruction set and adopts a 6-stage variable-length pipeline architecture to achieve high frequency and performance, meeting the demands of high-performance embedded scenarios. This core supports configurable dual-mode capabilities, allowing for switching between real-time processors and application processors. It also provides a 64-bit AXI system bus interface, AHB-Lite private peripheral interfaces, ILM/DLM interfaces, and slave interfaces.

Configurable on-chip SRAM for instructions and data, along with features like instruction cache (ICache), data cache (DCache), and Cluster Cache, collectively support the enhancement of system performance and efficiency. The core also features a configurable Cache Line Size of 64 bytes, MMU (Memory Management Unit), and single/double precision floating-point extension capabilities. Additionally, configurable PMP (Physical Memory Protection) is used to establish a trusted execution environment, meeting system security requirements.

The core supports standard JTAG and cJTAG debugging interfaces, as well as compile toolchains adhering to the RISC-V standard and Linux/Windows graphical integrated development environments (IDE). These features together constitute the robust feature set of the FSL91030M core, suitable for various application scenarios.
