COORDINATION OF CONNECTION INITIATION SCHEDULING IN A DISTRIBUTED STORAGE NETWORK (DSN)

摘要

A dispersed storage network (DSN) include multiple distributed computing systems distributed across time zones, each including a DSN memory. A global scheduling module identifies a number of the distributed computing systems operating in each of the time zones. For each distributed computing system operating in a particular time zone, the scheduling module selects a connection time based, at least in part, on the number of distributed computing systems operating in the particular time zone. The connection time selected for a particular distributed computing system specifies a recurring time period to be used by that system for initiating connections with a global coordination unit. The global scheduling module issues, to the distributed computing systems, scheduling messages that include information specifying a connection times for particular distributed computing systems.

1. A method for use in a dispersed storage network (DSN) including a plurality of distributed computing systems distributed across time zones, each computing system including a DSN memory, the method comprising:
identifying, at a global scheduling module used by the plurality of distributed computing systems, a number of the distributed computing systems operating in each of the time zones; for each distributed computing system operating in a particular time zone, selecting at the global scheduling module, a connection time based, at least in part, on the number of distributed computing systems operating in the particular time zone, wherein a connection time selected for a particular distributed computing system specifies a recurring time period to be used by the particular distributed computing system for initiating a connection with a global coordination unit; and issuing scheduling messages from the global scheduling module to the plurality of distributed computing systems, wherein the scheduling messages include information specifying a connection times for particular distributed computing systems.
