                draft-lachosrothenberg-alto-md-e2e-ns-00

Abstract

   Evolving networking scenarios (e.g., 5G) are considering the
   provision of value-added and on-demand end-to-end (E2E) network
   services in multi-domain (multi-operator/multi-technology)
   environments.  This document presents different initiatives, mainly
   within standardization efforts and research projects, working on E2E
   network services across multiple domains.  Problem statement and a
   layered network model are also described.  In addition, this document
   raises an initial proposal towards a new ALTO service in support of
   E2E network service requirements.  Finally, another important
   objective of this document is to begin a discussion about motivating
   use cases in scope of the ALTO WG after the re-chartering process.

1.  Introduction

   The fifth generation (5G) of cellular networks is not only considered
   an evolution but a revolution in the field of information and
   communication technologies [WHITE-PAPER-5G].  5G will support the
   creation of new and novel End-to-End (E2E) services, applications and
   complex use case scenarios, such as massive Internet of Things,
   extreme real-time communications, broadband access everywhere, higher
   user mobility.  All these scenarios and services are triggering a
   modification in the way telecommunications sector deploy new network
   services, shifting from a commonly manual and long process to a
