| Internet-Draft | Service Information YANG Model | July 2023 |
| Wang, et al. | Expires 8 January 2024 | [Page] |
Computing-Aware Traffic Steering (CATS) aims to solve the problem of how the network edge can steer traffic between clients of a service and sites offering the service. To achieve such scheduling, the network needs to aware the computing information of the service. This document defines a YANG data model for the computing information of the service for CATS.¶

Computing-Aware Traffic Steering (CATS) [I-D.ldbc-cats-framework] aims to solve the problem of how the network edge can steer traffic between clients of a service and sites offering the service. To achieve such scheduling, the network needs to aware the computing information of the service. The awareness methods are not limited to distributed, centralized, or hybrid[I-D.yao-cats-awareness-architecture]. This document defines a YANG data model for the computing information of the service transferring between the CATS-control center and the CATS-routers. Naturally, this data model could also be used for distributed solution.¶
This section presents a simplified graphical representation of the computing information model using a YANG tree diagram[RFC8340].¶
