     Required path properties for applying path aware networking in
                 integrated space-terrestrial networks
               draft-zheng-panrg-path-properties-istn-00

Abstract

   Integrated space-terrestrial networks are heterogeneous networks with
   various path characteristic, and usually belong to different
   administrative domains.  Therefore integrated space-terrestrial
   networks can be seen as a use case of path-aware networking.  This
   memo introduces requirements on path properties when applying path-
   aware-network in integrated space-terrestrial networks.

Requirements Language

   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 [RFC2119].

1.  Introduction

   In the integrated space-terrestrial networks, endpoint is capable to
   access space networks, mobile networks, and fixed networks.  These
   heterogeneous networks have essential difference on characteristics
   and come from different service providers, which makes it difficult
   to carry out unified management and control.  Furthermore, different
   with ground networks, the quality of links in space is fluctuating,
   the network topology changes dynamically, and the resources of space
   node is limited.  It is necessary to come out a system to release the
   burden of networks(especially space nodes with limited resource) and
   leaving the complex function to endpoint.  In other words, the path-
   aware network may help to cope with the dynamics of this kind of
   network.

   According to the definition of [RFC5136], a path is a series of links
   that connect a series of nodes from the source node to destination.
   The properties of path can be seen from the overall point of view, or
   decomposed into node properties and link properties.  Corresponding
   granular path awareness can be performed in the basis of the
   capability of the endpoint and/or the required quality of service.
   This memo will describe the required path properties from different
   granularity in integrated space-terrestrial networks.
