This memo discusses a proposed extension to the Internet architecture and protocols to provide integrated services, i.e., to support realtime as well as the current non-real-time service of IP. This extension is necessary to meet the growing need for real-time service for a variety of new applications, including teleconferencing, remote seminars,(More)
The architecture of the Internet is based on a number of principles, including the self-describing datagram packet, the end to end arguments, diversity in technology and global addressing. As the Internet has moved from a research curiosity to a recognized component of mainstream society, new requirements have emerged that suggest new design principles, and(More)
The DETER testbed is shared infrastructure designed for medium-scale repeatable experiments in computer security, especially those experiments that involve malicious code. The testbed provides unique resources and a focus of activity for an open community of academic, industry, and government researchers working toward better defenses against malicious(More)
Questioning whether layering is still an adequate foundation for networking architectures, this paper investigates non-layered approaches to the design and implementation of network protocols. The goals are greater flexibility and control with fewer feature interaction problems. The paper further proposes a specific non-layered paradigm called <i>role-based(More)
<i>sloppy This paper describes FARA, a new organization of, network architecture concepts. FARA (Forwarding directive, Association, and Rendezvous Architecture) defines an abstract model with considerable generality and flexibility, based upon the decoupling of end-system names from network addresses. The paper explores the implications of FARA and the(More)
This memo discusses methods for efficiently computing the Internet checksum that is used by the standard Internet protocols IP, UDP, and TCP.An efficient checksum implementation is critical to good performance. As advances in implementation techniques streamline the rest of the protocol processing, the checksum computation becomes one of the limiting(More)
Charter The goal of this project was to consider the following question: if we could now design the Internet from scratch, knowing what we know today, how would we make the basic design decisions? The phrase " design from scratch " implies that we deliberately set aside issues of migration—how we would get from where we are today to a new design tomorrow.(More)
Since 2004, the DETER Cybersecurity Testbed Project has worked to create the necessary infrastructure &#x2014; facilities, tools, and processes-to provide a national resource for experimentation in cyber security. The next generation of DETER envisions several conceptual advances in testbed design and experimental research methodology, targeting improved(More)
The DETER testbed provides infrastructure for conducting medium-scale repeatable experiments in computer security, especially experiments that involve malicious code. Built using Utah’s EMULAB, the DETER testbed has been configured and extended to provide stronger assurances for isolation and containment. This paper provides information on the capabilities(More)
This paper concerns the design of a flexible and efficient packet monitoring program for analyzing traffic patterns and gathering statistics on a packet network. This monitor operates in real time, using an analyzer which is an interpretive pseudo-machine driving object-oriented data collection programs. The pseudo-program for the interpreter is(More)
