        DHCP Options for Network-Assisted Multipath TCP (MPTCP)
                      draft-boucadair-mptcp-dhc-07

Abstract

   Because of the lack of Multipath TCP (MPTCP) support at the server
   side, some service providers now consider a network-assisted model
   that relies upon the activation of a dedicated function called MPTCP
   Conversion Point (MCP).  Network-assisted MPTCP deployment models are
   designed to facilitate the adoption of MPTCP for the establishment of
   multi-path communications without making any assumption about the
   support of MPTCP by the communicating peers.  MCPs located in the
   network are responsible for establishing multi-path communications on
   behalf of endpoints, thereby taking advantage of MPTCP capabilities
   to achieve different goals that include (but are not limited to)
   optimization of resource usage (e.g., bandwidth aggregation), of
   resiliency (e.g., primary/backup communication paths), and traffic
   offload management.

   This document focuses on the explicit deployment scheme where the
   identity of the MPTCP Conversion Point(s) is explicitly configured on
   connected hosts.  This document specifies DHCP (IPv4 and IPv6)
   options to configure hosts with Multipath TCP (MPTCP) parameters.
