# FemtoTCP
|
|
|
|
|
|
|
|
|
|
The smallest TCP/IP stack on the planet
|
|
|
|
|
|
|
|
|
|
## Description and project goals
|
|
|
|
|
|
|
|
|
|
FemtoTCP is a TCP/IP stack with no dynamic memory allocations, designed to be
|
|
|
|
|
used in resource-constrained embedded systems.
|
|
|
|
|
|
|
|
|
|
Endpoint only mode is supported, which means that femtotcp can be used to
|
|
|
|
|
establish network connections but it does not route traffic between different
|
|
|
|
|
network interfaces.
|
|
|
|
|
|
|
|
|
|
A single network interface can be associated with the device.
