Abstract:
In Traffic Engineered (TE) systems, it is sometimes desirable to
establish an end-to-end TE path with a set of constraints (such as
bandwidth) across one or more network from a source to a destination.
TE information is the data relating to nodes and TE links that is
used in the process of selecting a TE path. TE information is
usually only available within a network. We call such a zone of
visibility of TE information a domain. An example of a domain may be
an IGP area or an Autonomous System.
In order to determine the potential to establish a TE path through a
series of connected networks, it is necessary to have available a
certain amount of TE information about each network. This need not
be the full set of TE information available within each network, but
does need to express the potential of providing TE connectivity. This
subset of TE information is called TE reachability information.
This document sets out the problem statement and architecture for the
exchange of TE information between interconnected TE networks in
support of end-to-end TE path establishment. For reasons that are
explained in the document, this work is limited to simple TE
constraints and information that determine TE reachability.
