Parallel Packet Processing on Multi-core and Many- core Processors

چکیده
The Service-oriented Router (SoR), a highly functional router based on a novel router architecture, enables unprecedented web services traditional routers were unable to provide. The SoR performs Deep Packet Inspection (DPI) to analyze Layer 7 information, which is becoming increasingly difficult due to the substantial increase in Internet traffic. Meanwhile, multi-core processors and general-purpose manycore processors are increasing in popularity. These highly programmable many-core processors are suited for parallel packet processing and propose a parallelization method for packet inspection. The method is applied to NEGI, a software SoR simulator. The parallelized software is then implemented on a multi-core Xeon CPU to test for effectiveness and scalability. While the results confirm its scalability, we find that the throughput of the output process must be improved for SoRs to benefit from the proposed method. Keywords—Service-oriented router; multi-core; many-core; packet processing

Efficient parallelization of the genetic algorithm solution of traveling salesman problem on multi-core and many-core systems
Efficient parallelization of genetic algorithms (GAs) on state-of-the-art multi-threading or many-threading platforms is a challenge due to the difficulty of schedulation of hardware resources regarding the concurrency of threads. In this paper, for resolving the problem, a novel method is proposed, which parallelizes the GA by designing three concurrent kernels, each of which running some depe...

متن کاملA Performance Model for Network Processor Architectures in Packet Processing System
Network processors (NPs) are designed to provide both performance and flexibility through the implementation of both parallel and programmable architectures. Typically, such processors encompass a parallel processor core with several memories and specialized co-processors. A common task performed by such processors is packet processing that is both complex and highly repetitive. Consequently, t...
