Abstract

   This draft specs a JSON formatted RLOC-record for telemetry data
   which decapsulating xTRs include in RLOC-probe Map Reply messages.

1.  Introduction

   This document describes how the Locator/Identifier Separation
   Protocol (LISP) can obtain, measure, and distribute data-plane
   telemetry information.  LISP is an encapsulation protocol built
   around the fundamental idea of separating the topological location of
   a network attachment point from the node's identity
   [I-D.ietf-lisp-rfc6830bis].  As a result LISP creates two namespaces:
   Endpoint Identifiers (EIDs), that are used to identify end-hosts and
   routable Routing Locators (RLOCs), used to identify network
   attachment points.  LISP then defines functions for mapping between
   the two namespaces and for encapsulating traffic originated by
   devices using non-routable EIDs for transport across a network
   infrastructure that routes and forwards using RLOCs.

   This document specifies how a decapsulating xTR returns telemetry
   data to an encapsulating xTR using RLOC-probe messages defined in
   [I-D.ietf-lisp-rfc6833bis].

   Early versions of this document will define the type and format of
   the telemetry data and how it will be distributed.  Later versions of
   this document will describe how telemetry measurement will be
   performed.

2.  Definition of Terms

   Encapsulating xTR  is a LISP ITR, RTR, or PITR data-plane network
      element [I-D.ietf-lisp-rfc6830bis].  An encapsulating xTR
      typically sends RLOC-probe Map-Request messages to decapsulating
      xTRs to test for reachability of RLOC addresses.  For the design
      scope of this specification, RLOC-probes are also sent to obtain
      LISP telemetry data measured by a decapsulating xTR.
