System Requirements
- VM or physical server. Physical server will perform better and better utilize all CPU cores.
- One management network interface, completely separate from the traffic shaping interfaces. Usually this would be the Ethernet interface built in to the motherboard.
- Dedicated Network Interface Card
- NIC must have two or more interfaces for traffic shaping.
- NIC must have multiple TX/RX transmit queues. Here's how to check from the command line.
- Known supported cards:
- NVIDIA ConnectX-4 MCX4121A-XCAT
- Intel X710
- Intel X520
- Known supported cards:
- Ubuntu Server 22.04 or above recommended. All guides assume Ubuntu Server 21.10 or above. Ubuntu Desktop is not recommended as it uses NetworkManager instead of Netplan.
- Kernel version 5.14 or above
- Python 3, PIP, and some modules (listed in respective guides).
- Choose a CPU with solid single-thread performance within your budget.
- Recommendations for 10G+ throughput:
- Choose a CPU with solid single-thread performance within your budget. Generally speaking, any new CPU above $200 can probably handle shaping up to 2Gbps.
