Abstract

   This document defines requirements for signaling across different
   network environments, such as across administrative and/or technology
   domains.  Signaling is mainly considered for Quality of Service (Qos)
   such as the Resource Reservation Protocol (RSVP).  However, in recent
   years, several other applications of signaling have been defined.
   For example, signaling for label distribution in Multiprotocol Label
   Switching (MPLS) or signaling to middleboxes.  To achieve wide
   applicability of the requirements, the starting point is a diverse
   set of scenarios/use cases concerning various types of networks and
   application interactions.  This document presents the assumptions
   before listing the requirements.  The requirements are grouped
   according to areas such as architecture and design goals, signaling
   flows, layering, performance, flexibility, security, and mobility.
