Abstract

This document specifies a generic GRE-in-UDP encapsulation for tunneling network protocol packets across an IP network based on Generic Routing Encapsulation (GRE) [RFC2784] [RFC7676] and User Datagram Protocol (UDP) [RFC768] headers. The GRE header indicates the payload protocol type via an EtherType [RFC7042] in the protocol type field, and the source port field in the UDP header may be used to provide additional entropy.

Abstract

   This document specifies a method of encapsulating network protocol    packets within GRE and UDP headers.  This GRE-in-UDP encapsulation    allows the UDP source port field to be used as an entropy field.    This may be used for load-balancing of GRE traffic in transit    networks using existing Equal-Cost Multipath (ECMP) mechanisms.    There are two applicability scenarios for GRE-in-UDP with different    requirements: (1) general Internet and (2) a traffic-managed    controlled environment.  The controlled environment has less    restrictive requirements than the general Internet.
