This paper presents an alternative IP DSCP to MPLS DSCP mapping technique enabled by the use of symbiotic packets. MPLS interoperability and MPLS DiffServ scalability are the explanation for not choosing a much simpler solution (e.g. using the first 14 bits as a label and the next 6 for the DSCP). Evaluation of the method is carried out on an mpls-linux enabled testbed. Performance evaluation results show that the proposed extension enabled by symbiotic packets is a valuable add-on to the MPLS DiffServ architecture. A symbiotic packet is a packet that carries around encoded in its header status information or codewords. Symbiosis, meaning living together, i.e. the data packet's header and the encoded information 'live' together. As an application of the symbiotic packets, the paper presents a method for encoding DiffServ code points in MPLS labels.(Abstract)
