HTT Consulting AX Enterprize, LLC AX Enterprize, LLC Cisco Systems, Inc This document requests an Internet Protocol Number, an Ethertype, and UDP port assignment for SCHC. The Internet Protocol Number request is so that SCHC can be used for IP independent SCHC of other transports such as UDP and ESP. The Ethertype is to support generic use of native SCHC over any IEEE 802 technology for IP and non-IP protocols. The UDP port request is to support End-to-End SCHC through potentially blocking firewalls.
