For reliable data transmission between the peers, acknowledgement based retransmission protocol known as Automatic Repeat Request may be used where each retransmission can further segment the previously transmitted data packets. This type of data processing may lead to high memory requirements and high processing requirements. A method and apparatus are disclosed that maintain additional information about the data packets which enables virtual segmentation and packing on the transmitter side and on the receiver side, virtual duplicate detection, reordering and reassembly. Performing the segmentation, packing, duplicate detection, reordering and reassembly operations in virtual manner reduce the memory and processing requirements and this may lead to reduced power consumption and improved user experience."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for packet data unit processing","description":"In data communication systems, data packet processing for transmission and reception may go through different stages such as segmentation or packing of the data packets on the transmission side and du","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9843655","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
