The IESG has received a request from the Traffic Engineering Architecture and Signaling WG (teas) to consider the following document: - 'Problem Statement and Architecture for Information Exchange Between Interconnected Traffic Engineered Networks' <draft-ietf-teas-interconnected-te-info-exchange-05.txt> as Best Current Practice The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-05-10. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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 for the exchange of TE information between interconnected TE networks in support of end-to- end TE path establishment and describes the best current practice architecture to meet this problem statement. For reasons that are explained in the document, this work is limited to simple TE constraints and information that determine TE reachability.
