Telecom Packet Processing and Correlation Engine Using DPDK - Ilan Raman, Aviz Networks
The exponential growth in telecommunications users has led to significantly increased bandwidth requirements. As a result, telecom operators are seeking solutions to develop software-based, scalable packet processing products. This proposal explores the utiliisation of DPDK capabilities to build high-speed, line-rate telecom packet processing systems. These systems enable metadata extraction from control and user plane packets and achieve control-user correlation using DPDK hash algorithms. It provides the packet processing libraries to extract the protocol packets from different interfaces like N11, N4, N3, S1-U, S11 etc. And the packets from these different interfaces require the packet stripping, adjustment, modifications to extract the necessary data which is achieved using DPDK MBUF Packet processing library APIs. The proposal can scale to multiple cores per port using the efficient RSS load-balancing techniques offered in NiC using DPDK Flow modules. The modular and robust DPDK library APIs allow building such Packet processing systems in a very short span of delivery time with high efficiency and quality.
