                    The PPP Multilink Protocol (MP)


Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document proposes a method for splitting, recombining and
   sequencing datagrams across multiple logical data links.  This work
   was originally motivated by the desire to exploit multiple bearer
   channels in ISDN, but is equally applicable to any situation in which
   multiple PPP links connect two systems, including async links.  This
   is accomplished by means of new PPP [2] options and protocols.

   The differences between the current PPP Multilink specification (RFC
   1717) and this memo are explained in Section 11.  Any system
   implementing the additional restrictions required by this memo will
   be backwards compatible with conforming RFC 1717 implementations.

Acknowledgements

   The authors specifically wish to thank Fred Baker of ACC, Craig Fox
   of Network Systems, Gerry Meyer of Spider Systems, Dan Brennan of
   Penril Datability Networks, Vernon Schryver of SGI (for the
   comprehensive discussion of padding), and the members of the IP over
   Large Public Data Networks and PPP Extensions working groups, for
   much useful discussion on the subject.
