In 802.16 standards, PHS suppresses redundant parts of payload header in MAC service data unit. This paper proposes Label Switched Path-Payload Header Suppression (LSP-PHS), in which an MPLS-enabled backbone route compresses packets over an MPLS LSP without compression or decompression cycles at each router. It has two main contributions for MPLS-IPv6 header compression. First, LSP-PHS adds a new facility (MPLS/PHS) to the existing MPLS facilities. Second, it provides an analysis of the effect of implementing LSP-PHS on real-time and non-real-time IPv6 traffic in terms of QoS metrics.
