smoltcp

smoltcp

smoltcp is a standalone, event-driven TCP/IP stack that is designed for bare-metal, real-time systems. Its design goals are simplicity and robustness. Its design anti-goals include complicated compile-time computations, such as macro or type tricks, even at cost of performance degradation.

Features

smoltcp is missing many widely deployed features, whether by design or simply because no one implemented them yet. To set expectations right, both implemented and omitted features are listed.

Media layer

The only supported medium is Ethernet.

• Regular 802.3 frames are supported.
• 802.1Q is not supported.
• Jumbo frames are not supported.
• CRC calculation is not supported.
• ARP packets are supported.
• ARP probes or announcements are not supported.

IP layer

UDP layer
