A computer program product and a computer system for distributed dynamic sizing and load self-management for a relay infrastructure. Program instructions are executable to initiate, by the non-leaving relay in a relay infrastructure, an expansion process, in response to determining that a current load level reaches an expansion level and in response to determining that an overload condition of the relay infrastructure is satisfied; send to a server, by the non-leaving relay, an expansion message, in response to initiating the expansion process; send to the server, by the non-leaving relay, local statistics of endpoints of the non-leaving relay; shift, by the non-leaving relay, one or more endpoints of the non-leaving relay to a first new relay, in response to the server selecting from the endpoints an endpoint and converting the endpoint to the first new relay.

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

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.
