 Udp Stack
 ---------------------------
-	When send request, the protocol stack will add two bytes at the beginning of the business data.
-	It means the length of the business data.
-	The response data must begin with two bytes of length and business data as well. 
-	The protocol stack will parse the length of the response data to validate the integrity.
-	After verification, the protocol stack will set pure business data to the matched request.

-	The BusMessage must implements the 'match' method to match request via the received business data.

 Tcp Stack
 ---------------------------
-
-
+Have the same framework with the Udp Stack.
 
+Implements via nio. And have the combine-packet function.
 
 
 Http Stack
----------------------------
+---------------------------
+There is a thread pool in the protocol stack(org.wjd.net.http.conn).
+POOL_SIZE can be setted via the constructor method.
+MAX_SIZE indicate the max request that can be sent at the same time.
+
+The file upload-download function under org.wjd.net.http.file package.
