P8: P4 With Predictable Packet Processing Performance

Toward Predictable Performance in Software Packet-Processing Platforms

To become a credible alternative to specialized hardware, general-purpose networking needs to offer not only flexibility, but also predictable performance. Recent projects have demonstrated that general-purpose multicore hardware is capable of high-performance packet processing, but under a crucial simplifying assumption of uniformity: all processing cores see the same type/amount of traffic an...

Fast Packet Processing on High Performance Architectures

The rapid growth of Internet and the fast emergence of new network applications have brought great challenges and complex issues in deploying high-speed and QoS guaranteed IP network. For this reason packet classification and network intrusion detection have assumed a key role in modern communication networks in order to provide Qos and security. In this thesis we describe a number of the most ...

Predictable Packet Latency in Xen-ARM

SUMMARY In this paper, we address latency issue in Xen-ARM virtual machines. Despite the advantages of virtualization in mobile systems, the current Xen-ARM is difficult to apply to mobile devices because it has unpredictable I/O latency. This paper analyzes the latency of incoming packet handling in Xen-ARM, and presents how virtualization affects the latency in detail. To make the latency pre...
