		<description><![CDATA[&lt;i&gt;...can i implement all the TCP or UDP functions in the aplication layer?&lt;/i&gt;

I&#039;m not understanding the whole question.

If you are creating your own communications architecture, you can implement your own services any way you choose.

But what kind of &quot;network&quot; are you talking about? What will the physical medium be? Will existing telecommunications facilities be used? E.g., will you use any existing infrastructure at all? Would you expect a standard router for example to pass your traffic?

		<description><![CDATA[transort layer (the 4th OSI layer).
But the question now is can i remove the UDP protocol,there is some OSI or TCP/IP layers able to replace UDP services.
Because in TCP case,there is no layers combination able to substitute the TCP services.]]></description>

		<description><![CDATA[&lt;i&gt;Is it feasible to have a global communication network without the transport layer?&lt;/i&gt;

First, what do you mean by &quot;transport layer&quot;? Without knowing the services that you include, there&#039;s no way to know an appropriate answer. TCP handles most of the services commonly thought of for a &quot;transport layer&quot; in the OSI network model; and although UDP leaves out many of those services, it&#039;s also considered a &quot;transport layer&quot; protocol.

SNA, for example, doesn&#039;t exactly have a &#039;Transport Layer&#039;. Many of the services generally thought to be in a &#039;Transport Layer&#039; are provided over SNA through APPC and APPN. Without using APPC/APPN, a lot of underlying stuff needs to be attended to more carefully.

As such, I&#039;d guess that the answer has to be &quot;Yes.&quot;

But then, I suppose it also depends on what &quot;communication&quot; will be carried over the network. A TV communication network can be global without requiring a &#039;Transport Layer&#039;. Shortwave radio might be a great example of a basis for a kind of &quot;global communication network without the transport layer&quot;.

So, please provide a little more description of what is needed. It&#039;s too vague to be sure.
