Voice over IP (VoIP) typically uses the encapsulation
voice/RTP/UDP/IP.  When MPLS labels are added, this becomes
voice/RTP/UDP/IP/MPLS-labels.  For an MPLS VPN, the packet header is
typically 48 bytes, while the voice payload is often no more than 30
bytes, for example.  Header compression can significantly reduce the
overhead through various compression mechanisms, such as enhanced
compressed RTP (ECRTP) and robust header compression (ROHC).  We
consider using MPLS to route compressed packets over an MPLS Label
Switched Path (LSP) without compression/decompression cycles at
each router.  This approach can increase the bandwidth efficiency as
well as processing scalability of the maximum number of simultaneous
flows that use header compression at each router.  In this document,
we give a problem statement, goals and requirements, and an example 
scenario.
