Mongoose is ideal for embedded environments. It has been designed
for connecting devices and bringing them online.

has been on the market since 2004 and attracted
over 1 million cumulative downloads.

It provides easy to use event-driven interface that allows to implement
network protocols or scalable network applications  with little effort.
Mongoose helps developers to manage the complexity of network programming
and let them concentrate on the logic, saving time and money.
