Proceedings ArticleDOI
On runtime management in multi-core packet processing systems
Qiang Wu,Tilman Wolf +1 more
TL;DR: This work investigates the design of an efficient run-time management system that handles the allocation of processing tasks to processor cores that can adapt to dynamic changes in the workload and balance the utilization of all processing resources to maximize throughput.
Proceedings ArticleDOI
Attacks on Network Infrastructure
TL;DR: This paper demonstrates a specific attack that can launch a devastating denial-of-service attack by sending just a single packet and shows that defense techniques based on processor monitoring that have been proposed in prior work can help in detecting and avoiding such attacks.
Journal ArticleDOI
Runtime Task Allocation in Multicore Packet Processing Systems
Qiang Wu,Tilman Wolf +1 more
TL;DR: This work proposes a novel methodology for allocating tasks to processors to obtain runtime profiling information and to duplicate tasks with heavy processing requirements to obtain balanced workloads and reduce the complexity of packing tasks with different processing requirements.
Proceedings ArticleDOI
Dynamic workload profiling and task allocation in packet processing systems
Qiang Wu,Tilman Wolf +1 more
TL;DR: This work proposes a novel way of representing processing tasks, obtaining runtime profiling information, and mapping tasks to processors that can improve the system throughput by 2.39-2.89 times at a cost of 1.49-1.64 times higher inter-processor communication.
Proceedings ArticleDOI
Benchmarking BGP Routers
TL;DR: A novel benchmark is presented that evaluates the performance of the most commonly used Internet-wide routing protocol, the Border Gateway Protocol (BGP), for four different systems that implement BGP, including a uni-core and a dual-core workstation, an embedded network processor, and a commercial router.
