-\begin{comment}
-In this picture we try to define more which elements are in US and which are in KS.
-In the first implementation we will make an US implementation for our protocol with raw socket to validate our architecture
-and to make easier our kernel implementation that will communicate with this implementation.
-
Raw socket implementation will support all syscalls and it will be a copy of our kernel implementation.
-This implementation will have the same API and behavior with kernel implementation. The peer discover will be in
-Application implementation and it will be developer problems how to implement and how to manage it.
-When you make a syscall you need to pass the ips where the protocol can find the specify hash
-
-In the first implementation a swift socket will be available for only one operation transmit data or receive data.
-In the last implementation the swift protocol will be develop in kernel space, and it will be accessible with a datagram
-socket that will support all socket syscalls. It will intend to support both operations (receive/ send) data over only one socket.
