Abstract

   The Seamoby Candidate Access Router Discovery (CARD) protocol and the
   Context Transfer Protocol (CXTP) are experimental protocols designed
   to accelerate IP handover between wireless access routers.  These
   protocols require IANA allocations for ICMP type and options, Stream
   Control Transmission Protocol (SCTP) Payload Protocol Identifiers,
   port numbers, and registries for certain formatted message options.
   This document contains instructions to IANA about which allocations
   are required for the Seamoby protocols.  The ICMP subtype extension
   format for Seamoby has been additionally designed so that it can be
   utilized by other experimental mobility protocols, and the SCTP port
   number is also available for other experimental mobility protocols.

1.  Introduction

   The Seamoby Candidate Access Router Discovery (CARD) protocol
   [RFC4066] and the Context Transfer Protocol (CXTP) [RFC4067] are
   experimental protocols designed to accelerate IP handover between
   wireless access routers.  These protocols require IANA allocations
   for ICMP options and type, SCTP Payload Protocol Identifiers, port
   numbers, and the establishment of registries for certain formatted
   message options.  Because the protocols are experimental, there is no
   guarantee that they will ever see widespread deployment in their
   current form.  Consequently, it is prudent to conserve Internet
   numbering resources that might be needed for other protocols that
   could see wider deployment.  This document contains instructions to
   IANA for the Seamoby protocols.  Additionally, the ICMP subtype
   extension format has been designed so that it could be used by other
   experimental mobility protocols.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
   Allocation policy names Specification Required, IETF Consensus
   Action, and Designated Expert are to be interpreted as described in
   RFC 2434 [RFC2434].

2.  Common IPv4 and IPv6 Allocations

   IANA has assigned SCTP port numbers 5090 for use by [RFC4066] and
   5091 for use of [RFC4067].  See Section 5.2.1 of [RFC4066] for a
   description of the inter-access router CARD protocol use of SCTP, and
   Section 3.1 of [RFC4067] for a description of the inter-access router
   CXTP use of SCTP.

3.  IPv4 Allocations

   IANA has assigned ICMP type 41 for IPv4 identifying ICMP messages
   utilized by experimental mobility protocols such as Seamoby.  See
   Section 5.1.1 of [RFC4066] for a description of experimental mobility
   CARD ICMP messages and Section 3.2 of [RFC4067] for the CXTP ICMP
