Hi all,

This document provides clear description about why and how to extend BGP to advertise AppMetaData (including the Load Measurement Index for the attached EC Servers, the Capacity Index, and Site Preference Index), in order to improve latency and performance for 5G edge services and other similar scenarios.
Support adoption.

Best
Xuesong

> 2) What type of additional load this data to Basic Tunnel encapsulation

> 
> For example is the load placed by this draft equal or Less than the SR routing

> 
> 3) Will the addition of this information aid Routing in 5G networks?
