SANODEFER

SANODEFER is an acronym for Self-Organizing Network On Deferred Execution and Efficient Rebalancing. It is a theoretical framework in distributed computing and networked systems that analyzes how a network of computing nodes can coordinate the deferral of non-urgent tasks to off- peak times in order to balance load and reduce energy consumption.

The model identifies key components, including deferrable and urgent tasks, deferral windows, and node selection policies. Nodes communicate a compact state through a distributed protocol (variants use gossip or centralized controllers) to decide whether to execute or defer tasks. The approach emphasizes locality, scalability, and resilience to node churn.

Goals include lowering peak demand, improving resource utilization, and enabling heterogeneous hardware to contribute according to capability. SANODEFER frameworks typically incorporate load-aware deferral, SLA constraints, and mechanisms to reassign deferred work if conditions change. They also address fault tolerance and fairness among participating nodes.

Evaluation is conducted primarily through simulations and small-scale pilots, with metrics such as deferral rate, tail latency, energy savings, and SLA impact. SANODEFER is not a single product but a family of models and policies used in research and experimental deployments, particularly in data centers, edge computing, and large-scale HPC workflows.
