An Empirical Study of Method In-lining for a Java Just-in-Time Compiler: Dynamic compilation systems need to reconcile the conflicting requirements between fast compilation speed and fast execution performance. We would like the system to generate highly efficient code for good performance, but the system needs to be lightweight enough to avoid any startup delays or intermittent execution pauses that may occur due to the runtime overhead of the dynamic compilation.

Listen and Whisper: Security Mechanisms for BGP: The Internet is a collection of autonomous systems (AS's), numbering more than 14,000 in a recent count. The inter-domain routing protocol, BGP, knits these autonomous systems together into a coherent whole

STRIDER: A Black-box, State-based Approach to Change and Configuration Management and Support: We describe a new approach, called Strider, to Change and Configuration Management and Support (CCMS). Strider is a black-box approach: without relying on specifications, it uses state differencing to identify potential causes of differing program behaviors, uses state tracing to identify actual, run-time state dependencies, and uses statistical behavior modeling for noise filtering.

Distributed Tarpitting: Impeding Spam Across Multiple Servers: This paper describes an Irish ISP's attempts to combat the abuse of resources caused by unsolicited commercial email. We describe the extension of a multicast system, used to implement POP-before-SMTP relaying, to share information about remote mail servers between multiple mail systems.

Running BSD Kernels as User Processes by Partial Emulation and Rewriting of Machine Instructions: his paper proposes a new implementation method of user-level OSes by using partial emulation of hardware and static rewriting of machine instructions. In this method, privileged instructions and their related non-privileged instructions in a native operating system are statically translated into subroutine calls that perform emulation.

Operating System I/O Speculation: How Two Invocations Are Faster Than One : In the past decade, the gap between processing speeds and disk access times has increased by an order of magnitude [1]. At the same time, although memory sizes have increased substantially, so have application data requirements. Systems therefore continue to swap their data sets to and from disk as they are often too large to all fit in memory.

StarFish: Highly Available Block Storage: In this paper, we describe the StarFish system, which provides host-transparent geographically-replicated block storage. The StarFish architecture consists of multiple replicas called storage elements (SEs), and a host element (HE) that enables a host to transparently access data stored in the SEs, as shown in Figure 1. StarFish is a software package for commodity servers running FreeBSD that communicate by TCP/IP over high-speed IP networks.

Flexibility in ROM: A Stackable Open Source BIOS: The personal computer (PC) basic input output system (BIOS) remains one of the last bastions of closed source software. The reasons for this are many, but the most prominent is that many of the hardware interfaces in modern PC chipsets are covered by non-disclosure agreements. NDAs greatly limit the set of systems that an open source BIOS could support. Additionally, technical barriers to entry at the firmware/BIOS level are significant.

SkipNet: A Scalable Overlay Network with Practical Locality Properties: Scalable overlay networks, such as Chord [27], CAN [21], Pastry [23], and Tapestry [32], have recently emerged as flexible infrastructure for building large peer-to-peer systems. A key function that these networks enable is a distributed hash table (DHT), which allows data to be uniformly diffused over all the participants in the peer-to-peer system.

Scriptroute: A Public Internet Measurement Facility: The ability to measure the Internet is of widespread value for diagnosing connectivity problems and understanding Internet topology [20,53], routing [35,54] and performance [3,51]. This paper considers a simple question: what is the right architecture for a generally available network measurement facility?
