Abstract

   This document proposes a new, backwards-compatible, approach to
   packet forwarding, where the service required rather than the IP
   address required acts as the vector for routing packets at the edge
   of the network.

1.  Introduction

   An important aspect of the Internet today is that it is no longer a
   uniform space with uniform requirements.  For both technical and
   economic reasons, we see an emerging trend of usage scenarios that
   are confined to some form of limited domain, and which inevitably
   lead to applications and protocols that are only suitable within a
   given scope [I-D.carpenter-limited-domains].  This trend collides
   immediately with two factors: the original design concept of an
   Internet with end to end IP transparency (such that any locally
   defined protocol running over IP is almost certain to escape the
   local network), and with the increasing presence of interfering
   middleboxes.  In this emerging context, where end to end IP service
   is no longer a safe assumption, and where there is increasing demand
   for specific services, this document proposes a new, backwards-
   compatible, approach to packet forwarding, where the service required
   rather than the IP address required acts as the vector for routing
   packets at the edge of the network.  This is known as Service Based
   Packet Forwarding (SBPF) or Service Oriented IP (SOIP).

   We propose an addition to the existing core function of the network,
   which is reachability over IPv6 or IPv4.  Today, IP is focussed on
   reachability, using best effort forwarding both to find a route and
   to automatically share transmission resources in a simple and low-
   cost way.  As a result, transport protocols such as TCP and UDP learn
   little or nothing about the network, beyond congestion or loss
