Whats the difference between protocol encapsulation and protocol conversion?

Protocol Encapsulation means that you are transmitting one protocol over the top of another; typically a legacy protocol, such as SNA or X25, over an IP network. This means that all the legacy protocol’s header information and protocol handling is still being performed, in addition to the underlying IP protocol. Apart from being less efficient than protocol conversion, any investment in this approach only increases your investment in legacy-related communications. Protocol Conversion means that one protocol is actually terminated and truly converted before messages are forwarded. This is the approach taken by ComNet. The benefits of protocol conversion are that it is more efficient and that your investment in this approach is directed toward true migration toward TCP/IP.
