reservv

Reservv, stylized as reservv, is a proposed framework and software platform for reserving and scheduling access to shared resources in distributed systems. It aims to enable clients to express requirements for resources such as compute time, storage, network bandwidth, or physical equipment, and for resource managers to allocate time slots or quantities without overlap. The core idea is to decouple the request from the allocation and to support cross-domain reservations spanning multiple subsystems.

The architecture typically comprises a client library, a reservation service, a resource catalog, and a policy engine. Clients submit reservation requests with metadata including resource type, quantity, duration, start time, and constraints. The reservation service negotiates with resource managers, resolves conflicts via defined policies, and returns confirmations or rejections. A state machine tracks reservation lifecycles from initiation, through activation, to release and audit.

Common features include conflict-free scheduling, time-based access windows, revocation and expiration handling, access control, and audit trails. Security and privacy concerns address authenticated requests and isolation between tenants. Real-world implementations are experimental and often prototyped within cloud orchestration platforms or research testbeds.

Limitations include the complexity of cross-domain integration, variability in resource models, and the need for standardized semantics. Ongoing work focuses on interoperability and performance guarantees.
