One thing I would suggest reading is
<URL:ftp://ftp.cs.unc.edu/pub/techreports/93-047.pdf>; it describes
several systems for managing messages (with headers and trailers) in
network protocols. Especially, you might want to look at the x-kernel and
its data structures (see section 3.2 of that report) for messages. The
x-kernel's home page is at
<URL:http://www.cs.arizona.edu/projects/xkernel/>; you can get titles of
more detailed papers to search for there.
