Context replication increases header compression gains by reducing 
   the redundancy between flows via efficient replicate (IR-CR) packets. 
   The optimum design of IR-CR packet formats requires elaborate    
   understanding of the inter-flow redundancy. As context replication is 
   most well-suited for TCP, this document presents a statistical 
   analysis of TCP/IP inter-flow field behaviour. Based on the analysis, 
   recommendations on ROHC-TCP packet format specifications for context 
   replication are made. It is also shown that inter-flow field 
   behaviour is inherently and significantly asymmetrical, and various 
   ways of handling it are considered. Finally, based on the inter-flow 
   behaviour of TCP Window field, it is noted that current encoding 
   methods do not compress it efficiently.

	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
