Publication number: 20150269207Abstract: A method and system for simple and efficient recycling of entity IDs in a network may rely upon two tables storing records associated with a particular entity ID while avoiding the use of timestamps or a common time source. A first table may store X number of records associated with active entities, including active entity IDs. A second table, referred to herein as an entity ID table, may store Y number of records associated with deactivated entities, including available entity IDs for reuse and a delete index, which may record an ordinal value associated with deactivated entity IDs. The two tables may enable fast and computationally efficient recycling of entity IDs without having to perform costly sorting operations and without the use of timestamps or a common time source.Type: ApplicationFiled: March 18, 2014Publication date: September 24, 2015Inventor: Cong Deng
