[1]. https://datatracker.ietf.org/doc/html/draft-ietf-idr-5g-edge-service-m= etadata-19#section-4.7 In the section 4.7, a untilzation sub-TLV is described.

However, I suggest to change it to the available capacity, i.e., how mu= ch of this capacity is currently available for future usage. In fact, it c= an be calculated out from the Utilization TLV by using the total capacity m= inus the Utilized capacity. After the modification, the total capacity in section 4.6 can be used a= s the weight for load balancing, which is relatively static; similarly, the= available capacity can also be used as the weight for load balancing, whic= h is relatively dynamic. Which one would be used on the Ingress (decision p= oint) is the decided by the Ingress itself. The modification can reduce the minus process. [Linda] How about changing the title of section 4.7 to "Service-Oriented Av= ailable Resource Sub-TLV"? We can use the Flag P (single bit) to indicate the value field. When it is set to 1, it indicates the value is the Service-Oriented Available Resource in percentage. When the "P" flag is set to 0, = the value in this Sub-TLV is the abstract value of the available resource.

The edge service Metadata can be used by the ingress routers in the 5G Local Data Network to make path selections not only based on the routing cost but also the running environment of the edge services. The goal is to improve latency and performance for 5G edge services. The extension enables an edge service at one specific location to be more preferred than the others with the same IP address (ANYCAST) to receive data flow from a specific source, like a specific User Equipment (UE).

[Linda] How about changing the title of section 4.7 to “Service-Oriented Available Resource Sub-= TLV"?

We can use the Flag P (single bit) to indic= ate the value field. When it<= /span>

       &= nbsp;  is set to 1, it indicates the value is the Service-Oriented

       &= nbsp;  Available Resource in percentage. When the "P" flag i= s set to 0, the

       &= nbsp;  value in this Sub-TLV is the abstract value of the available

       &= nbsp;  resource.<= /p>

Thanks, Linda=

Abstract:

 

   This draft desc= ribes a new Metadata Path Attribute and some Sub-TLVs

   for egress rout= ers to advertise the Metadata about the attached edge

   services (ES).&= nbsp; The edge service Metadata can be used by the ingress

   routers in the = 5G Local Data Network to make path selections not only

   based on the ro= uting cost but also the running environment of the

   edge services.&= nbsp; The goal is to improve latency and performance for 5G

   edge services.<= /span>

 

   The extension e= nables an edge service at one specific location to be

   more preferred = than the others with the same IP address (ANYCAST) to

   receive data fl= ow from a specific source, like a specific User

   Equipment (UE).=
