Jordi,

 

Your draft describes two aspects of the service perf= ormance impacted by the Computing: Service Deployment and  Service (Pa= th) Selection. Those two should be separated, as the Service Deployment bel= ongs to the OpsArea, and the Service selection (including Network Path & DCs that host the services) belongs to the R= outing area.

 

https://datatracker.ietf.org/doc/draft-ie= tf-idr-5g-edge-service-metadata/ has proposed a new Metadata Path Attri= bute and some Sub-TLVs  for egress routers to advertise the Metadata about the attached edge  services (ES).&nbs= p; The Edge Service Metadata can be used by the ingress routers in the 5G L= ocal 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.

 

 

Can this Metadata Path Attribute address the problem= stated in your draft?  I CC’ed the IDR WG, so your comments on = the Path Selection can be visible to them.

 

Thanks, Linda

Subject: [Cats] New draft on joint exposure of network and compute i= nformation

 

Dear CATS and ALTO WG mailing list member= s,

 

We submitted a new draft on joint exposur= e of network and compute information for service placement and selection: https://datatracker.ietf.org/doc/draft-rcr-opsawg-operational-compute-metri= cs/

 

 

Joint Exposure of Network and Compute= Information for Infrastructure-Aware Service DeploymentJoint Exposure of N= etwork and Compute Information for Infrastructure-Aware Service Deployment

This draft focuses on the problem of expo= sing both network and compute information to the service provider/applicati= on to support service placement and selection decisions. ALTO provides an interface for network information exposure to = the service provider/application; thus, an approach is to leverage and exte= nd it with compute metrics. CATS also needs to develop compute metrics to s= upport traffic steering decisions. The common ground is in these compute metrics, which could be reused acros= s the various use cases (e.g., consumed by the network as in CATS or consum= ed by the application as in ALTO).

 

This draft also aims at providing a frame= work for continuing the discussion initiated during IETF 117 regarding the = presentation "Compute-aware metrics: CATS working with ALTO": https://datatracker.ietf.org/doc/slides-117-alto-compute-aware-metrics-cats= -working-with-alto/  

 

We would like to seek feedback from both = working groups on developing compute metrics that can be reused for differe= nt use cases, to avoid duplicated work and increase the effectiveness of future standards.

 

Thanks,

Jordi
