Peakiq can use P4 inside opensourcenetworking workflows to make implementation and maintenance easier to reason about.
This page explains where P4 fits, what problems it solves, and why it belongs in the Network Solutions stack.
P4 is an open-source domain-specific programming language for programming the data plane of network devices such as switches, NICs, and routers. It allows network operators and developers to define how packets are processed, enabling unprecedented flexibility and control.
🚀 Key Features
- Open-source and vendor-independent
- Define custom packet-processing pipelines
- High-performance data plane programming
- Supports programmable switches and NICs
- Integration with P4Runtime for control plane interaction
- Works with network simulators like BMv2
🛠How It Works
P4 allows you to describe the behavior of packet headers, tables, and actions in a network device. The P4 compiler translates your program into a target-specific implementation that runs on programmable hardware or software switches, allowing full control over packet forwarding.
🎯 Use Cases
- Software-Defined Networking (SDN)
- Custom routing and switching behaviors
