 Smews is operating system desing to support both IPv4 and IPv6 ant to be used as an embedded web server. The project is under the CeCILL license and the program's sources are available on GitHub.This include the capicity to be recognized in a network and exchange with peripherals via the internet protocol TCP/IP.
-The state of art show us that the internet of thing answer the quesion of the unvaibilty for the devices running around us to communicate.
+The state of art show us that the internet of thing answer the question of the unavailability for the devices running around us to communicate.
 The well-known standard for this kind of system is the UPnP but this technology have several drawbacks like security or the unavailability to create hierarchical network.
 Because of the hardware constrained devices, it's important to keep in mind that the connexion are available in a little perimeter, the physical layer of this communication is therefore limited to (USB, Bluetooth, ZigBee...).

		+	Back in the day, UPnP has take a large advance but the security of the system is always poorer than Smaws can accomplish. This is a reason why Smews could be more popular in the Open Source community and the development could be assure by independent programmer.

		+	In conclusion this research prove that tiny devices could easily be upgrade to network and to keep advantge of his size and security design it's make an intersting advanced in the communication between devices and interaction. It's an interesting alternative to UPnP for developer who wants his personal area network.

 The authors propose an architecture that can handle simultaneous connections. Smews is designed to use a single shared buffer so only one information is processed at a time. Smews share information between the IP Stack and the application for an improvement of performance. For the same goal, Smews does not waiting the acknowledgement for static file like a traditional TCP stack. It retrieve data in case of retransmission and defined shared buffer is provided to transmit server-side generators.
 As a result this server is able to have several in-flight packets for most of the Web contents it serves and have large MSS size handle even with a small sized buffer.This architecture can use standard file like html, css, js and some native code.
 Miniweb and µIP are the 2 others Embedded web servers use for the comparison. They show us that Miniweb is just able to use static files and µIP use more memory thanks to the protothreads.
 The comparison sets out that Smews is more efficient than the 2 others explained with their architecture designed for minimal shared content.
 In Smews, OgO files and static web files are preproceed to create C content. The compiler generates the binairies from C files and S-S generators. This is the best way to incrust the static content into the hardware and save some memory.
