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

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-p...

Scheduling Algorithms for Asymmetric Multi-core Processors

— Growing power dissipation due to high performance requirement of processor suggests multicore processor technology, which has become the technology for present and next decade. Research advocates asymmetric multi-core processor system for better utilization of chip real state. However, asymmetric multi core architecture poses a new challenge to operating system scheduler, which traditionally ...

Task Partitioning for Multi-core Network Processors

Network processors (NPs) typically contain multiple concurrent processing cores. State-of-the-art programming techniques for NPs are invariably low-level, requiring programmers to partition code into concurrent tasks early in the design process. This results in programs that are hard to maintain and hard to port to alternative architectures. This paper presents a new approach in which a high-le...

Towards High-performance Flow-level Packet Processing on Multi-core Network Processors

There is a growing interest in designing high-performance network devices to perform packet processing at flow level. Applications such as stateful access control, deep inspection and flow-based load balancing all require efficient flow-level packet processing. In this paper, we present a design of high-performance flow-level packet processing system based on multi-core network processors. Main...

Load Scheduling for Flow-based Packet Processing on Multi-core Network Processors

Load scheduling is critical to the performance of parallel processing network devices. With the rapid development of multi-core technology, efficient load scheduling scheme optimized for multi-core network processors becomes increasingly important and motivates intensive research today. In this paper, we study the relationship between two canonical scheduling schemes, packet-level scheduler and...
