Encapsulating IP in UDP
draft-xu-intarea-ip-in-udp-10
Abstract
Existing IP-in-IP encapsulation technologies are not adequate for
efficient load balancing of IP-in-IP traffic across IP networks.
This document specifies additional IP-in-IP encapsulation technology,
referred to as IP-in-UDP (User Datagram Protocol), which can
facilitate the load balancing of IP-in-IP traffic across IP networks.

1. Introduction
To fully utilize the bandwidth available in IP networks and/or
facilitate recovery from a link or node failure, load balancing of
traffic over Equal Cost Multi-Path (ECMP) and/or Link Aggregation
Group (LAG) across IP networks including Wide Area Networks (WAN) and
Data Center Networks (DCN) is widely used. There are increasing
applications of the IP-in-IP encapsulation on the WAN and DCN
environments, such as Global Accelerator (GA) on public cloud
providers' WAN and high-performance DCNs. [RFC5640] describes a
