Data caches of various forms have been widely deployed in the context of commercial and research and education networks, but their common positioning at the Edge limits their utility from a network operator perspective. When deployed outside the network core, providers lack visibility to make decisions or apply traffic engineering based on data access patterns and caching node location.

As an alternative, in-the-network caching provides a different type of content delivery network for scientific data infrastructure, supporting on-demand temporary caching service. It also allows providers to design data hotspots into the network topology, and to manage traffic movement and congestion by data-driven traffic engineering. There is also an opportunity for strategies around regional in-network cache placement to reduce the data access latency for the users and increase the overall computing application performance.

We will describe the status of in-network caching nodes deployed within ESnet in support of the US CMS data federation, which includes caches maintained by the University of Wisconsin-Madison, MIT, UCSD, Caltech, and ESnet. We will describe the container and networking architecture used to deploy data caches within ESnet, and update on the evolving tooling around service management lifecycle. An analysis of cache usage will also be provided along with an outlook for expanding the in-network cache footprint.
