Buffer management system. A ring buffer may be implemented. The ring buffer includes a number of zones. Each of the zones includes state fields. The state fields include a filled indicator indicating whether the zone is full. The state fields for the zone further include a committed indicator indicating whether data in the zone is readable. The state fields for the zone also include a recycling indicator indicating whether the zone can be recycled. The ring buffer includes entries in the zones. Each of the entries includes state information. The entry state information includes a zone offset indication indicating a memory offset into the zone. The entry state information further includes a size indicating the size of the entry. The entry state information also includes a committed indicator indicating that the entry is readable.
