This paper presents Ally, a server platform architecture that supports compute-intensive management services on multi-core processors. Ally introduces simple hardware mechanisms to sequester cores to run a separate software environment dedicated to ...

Packet parsing is necessary at all points in the modern networking infrastructure, to support packet classification and security functions, as well as for protocol implementation. Increasingly high line rates call for advanced hardware packet processing ...

Regular expression matching is the core engine of many network functions such as intrusion detection, protocol analysis and so on. In spite of intensive research, we are still in need of a method for fast and scalable regular expression matching, where ...

TCP and IP fragmentation can be used to evade signature detection at Intrusion Detection/Prevention System (IDS / IPS). Such fragments may arrive out-of-sequence to escape from being detected by the string matching algorithm of IDS / IPS. The common ...

We study a streaming network application -- video transcoding to be executed on a multi-core server. It is important for the scheduler to minimize the total processing time and preserve good video quality in an energy-efficient manner. However, the ...

As processor power density has increased at an alarming rate, chip/core temperature control becomes critical in satisfying given thermal constraint and avoiding hotspots. Unlike "run-to-finish" applications whose temperature will simply rise to ...

We present the Homogeneous-Parallel-Concentrated-Mesh topology (HPC-Mesh). This NoC topology provides four disjoint homogeneous concentrated mesh networks. The network interface at each core provides connectivity to all these networks by using a novel ...

Sketch-based algorithms are widely used in networking applications due to its many good attributes. We propose to use Graphics Processing Unit (GPU) as an accelerating engine to offload heavy sketch computations for network traffic change detection. Our ...

Network programming is widely understood as programming strictly defined socket interfaces. Only some frameworks have made a step towards real network programming by decomposing networking functionality into small modullar blocks that can be assembled ...

Regular expression (Reg Ex) matching plays an important role in many modern intrusion detection systems (IDS). DFA is an effective way to perform regular expression matching. However, the prohibitive memory requirement makes DFAs impractical for many ...

Peer-to-peer (P2P) applications distribute large files fast. That makes them popular on the Internet and has motivated their use on data center networks. On data center networks, however, these Internet applications waste bandwidth. To fully use ...

The packet cache router enabling the packet-level redundant data elimination is effective to reduce the P2P swarm traffic traversing ISP inter-domain links. To deploy the packet cache router in the ISP networks, the high performance packet processing is ...

Programmable packet processors have replaced traditional fixed-function custom logic in the data path of routers. This programmability introduces new vulnerabilities in these systems that can lead to new types of network attacks. We propose a modular ...

Network virtualization has gained a lot of attention recently, because of some new interesting proposals in the field (i.e. Open Flow). This trend has had the effect of pushing some filtering operations up at the software level: i.e. extract a ...

Many algorithms and hardware architectures are proposed to increase processing speed of time-critical operations in the field of longest prefix matching, packet classification and regular expression matching. Despite this fact, there is still no free ...

The Ensemble Routing[1] architecture (presented at ANCS 2010) implements multipath routing for data center networks. Rather than managing individual flows, ensemble routing manages flows in groups or ensembles to provide scalable responsive management ...

Content-Centric Networks (CCN) provide substantial flexibility for users to obtain information without regard to the source of the information or its current location. Publish/subscribe (pub/sub) systems have gained popularity in society to provide the ...

The largest enterprise networks already contain hundreds of thousands of hosts. Enterprise networks are composed of Ethernet subnets interconnected by IP routers. These routers require expensive configuration and maintenance. If the Ethernet subnets are ...

This paper presents a novel approach to minimally invasive service differentiation in packet-switched networks. Instead of actively managing service allocation, a simple differentiated queueing algorithm provides traffic classes with essentially the ...

There has been a significant increase in the Internet dynamics in the past decade. This has put tremendous pressure on the performance of routing protocols as they need to keep updating their routing information with every network change across the ...

Network virtualization has emerged as a powerful technique to deploy novel services and experimental protocols over shared network infrastructures. Although recent research has highlighted field programmable gate arrays (FPGAs) as attractive platforms ...
