Stargate-N1025 DPU
SmartNIC
Overview
Resnics Stargate-N1025 is a P4 programmable cloud-native SmartNIC with independent intellectual property rights. It supports server boot via cloud disk, and includes 2x 25G Ethernet ports, 1x 1000BASE-T GE management Ethernet port.
The P4 network acceleration engine is a VLIW ISA P4 processor designed for vSwitch acceleration, with specific P4 instructions to complete protocol parsing, packet encapsulation and decapsulation. And it supports tens of millions of flow tables, and achieve the wire speed packet forwarding meanwhile.
Target Application
Stargate-N1025 SmartNIC features high-performance, low-latency, high-flexibility and low-power dissipation. The dynamic programmable P4 engine enables users to flexibly extend or customize new protocols with the P4 language, to update and upgrade P4 applications without interrupting business flow.
Therefore, Stargate-N1025 can be applied to different application scenarios in different areas, and it’s a competitive network application acceleration solution such as OVS, NFV, SDN vRouter, 5G UPF, etc.
