In particular, embodiments described herein provide systems and methods for associating packets with the devices from which they were communicated, despite the obfuscatory behavior of any network address translators (NAT). A processor first receives packets that were collectively communicated, by a plurality of devices, via a NAT-serviced LAN. The processor aggregates the packets into multiple packet aggregations on a per device basis. Fields that are contained in the respective packet headers of the packets are used. The packet aggregations may be grouped. The embodiments use unencrypted lower-level information (including, for example, IPIDs and domain names), such that aggregation and grouping may be successfully performed even if information in the application layer is encrypted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for identifying devices behind network address translators based on TCP timestamps","description":"Methods and systems for monitoring activity on a local area networks (LAN).
