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