Network Entitlement: A contract-based network sharing solution

What this post added

Introduced Network Entitlement, a contract-based network sharing solution that reserves bandwidth per service for a predefined period for each region. This framework addresses challenges in capacity utilization, service isolation, accountability, SLO guarantees, and contextual tax on services by providing isolation for reliability, guarantee and accountability, abstraction of network complexity, observability, and a work-conserving approach. The solution comprises four components: contract abstraction, dynamic SLO-based guarantee service, runtime enforcement system, and policy verification using production drills.
