PDCP Packet Processing Library in DPDK - Understanding Libpdcp Implementation

Learn about PDCP (Packet Data Convergence Protocol) implementation in DPDK through this technical conference talk that explores the crucial role of PDCP in UMTS, LTE, and 5G air interfaces. Discover how PDCP operates within the radio protocol stack, positioned between RLC layer and upper protocol layers, managing both user plane and control plane data transfer. Explore essential security features including ciphering and integrity protection, along with advanced capabilities such as in-order delivery, duplicate discard, windowing-based anti-replay protection, and timer-based SDU discard. Examine how PDCP leverages various DPDK libraries including rte_reorder, rte_cryptodev, rte_security, rte_timer, and rte_event. Gain practical insights into Lib PDCP's standard abstraction for PDCP datapath processing, understanding protocol-specific handling and cryptodev offloading capabilities from an application usage perspective.
