IDR WG,



I think AppMetaData is useful for optimized inter-domain routing in 5G network and therefore support the WG adoption. Thanks!



Haoyu



---------------------------------------------------------------

Hi everyone,



    I have read through the draft and support its adoption.

    The additional information is useful for inter-domain routing within 5G networks and will improve routing in 5G networks.



Best Regards,

Huaimo

This draft proposes a new SubTLV (AppMetaData) for the BGP Tunnel Encapsulation Attribute [RFC9012] that indicates the running status and environment of directly attached 5G Edge Computing (EC) instances.



The AppMetaData can be used by routers in the 5G Local Data Network to make path selection not only based on the routing distance but also the running environment of the destinations. The goal is to improve latency and performance for 5G EC services.



In your discussion of this adoption call, please consider these questions:



1) The addition of this type of information to tunnels is useful for inter-domain routing within 5G networks?



2) What type of additional load this data to Basic Tunnel encapsulation [RFC9012]?



For example is the load placed by this draft equal or Less than the SR routing additions from such as draft-ietf-idr-segment-routing-te-policy?



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



Cheers, Sue Hares
