Distributed dynamic sizing and load self-management for a relay infrastructure

摘要

Methods for distributed dynamic sizing and load self-management for a relay infrastructure. In one method, a relay in a relay infrastructure determines whether a current load level of the relay reaches an expansion level of the relay and whether an overload condition of the relay infrastructure is satisfied, and the relay initiates an expansion process in response to the determination. In another method, a relay in a relay infrastructure determines whether in response to determining that an underload condition of the relay infrastructure is satisfied, and the relay initiates a contraction process in response to the determination. In yet another method, a relay in a relay infrastructure determines whether a tolerance-load condition of the relay infrastructure is satisfied, and the relay in initiates a load self-management process in response to the determination.
