Abstract:

   This document specifies two complementary mechanisms for carrying the
   CATS Service Identifier (CS-ID) and network/computing requirement
   parameters in client service request packets within the Computing-
   Aware Traffic Steering (CATS) framework.

   Mode A uses IPv6 Extension Headers to carry CS-ID and requirement
   parameters as hop-by-hop or destination options, enabling in-band
   signaling that is visible to all CATS-aware network nodes along the
   path.  Mode B uses a payload-based TLV structure that is transport-
   protocol agnostic and can be used with both IPv4 and IPv6, as well as
   with encrypted transports.

   The document defines the Virtual Placeholder Address (VPA) prefix
   requirements, the CATS Service Request Extension Header (CSREH)
   format, the CATS Service Request TLV format, and the CATS_PACKET_IN
   process for handling these packets at ingress CATS-Forwarders.
