    Network Working Group R. Stine, Editor Request for Comments: 1147 SPARTA, Inc. FYI: 2 April 1990 FYI on a Network Management Tool Catalog: Tools for Monitoring and Debugging TCP/IP Internets and Interconnected Devices Status of this Memo The goal of this FYI memo is to provide practical information to site administrators and network managers. This memo provides information for the Internet community. It does not specify any standard. It is not a state- ment of IAB policy or recommendations. Comments, critiques, and new or updated tool descriptions are wel- come, and should be sent to Robert Stine, at [email protected], or to the NOCTools working group, at [email protected]. Distribution of this memo is unlimited. 1. Introduction This catalog contains descriptions of several tools available to assist network managers in debugging and main- taining TCP/IP internets and interconnected communications resources. Entries in the catalog tell what a tool does, how it works, and how it can be obtained. The NOCTools Working Group of the Internet Engineering Task Force (IETF) compiled this catalog in 1989. Future editions will be produced as IETF members become aware of tools that should be included, and of de®ciencies or inaccuracies. Developing an edition oriented to the OSI protocol suite is also contemplated. The tools described in this catalog are in no way endorsed by the IETF. For the most part, we have neither evaluated the tools in this catalog, nor validated their descriptions. Most of the descriptions of commercial tools have been provided by vendors. Caveat Emptor. 1.1 Purpose The practice of re-inventing the wheel seems endemic to the ®eld of data communications.

MH 7C-211 6170 Filing Case- 39394-11 Bayer, D. L. MH 7C-207 3080 ABSTRACT A structured operating system, MERT, consisting of a set of autonomous processes has been designed and implemented on a PDP-11/45 computer in Department 1352. The MERT system is a multi-environment, real-time operating system consisting of a set of basic kernel procedures providing services for the inde• pendent processes which support the different operating system environments. A well-developed set of inter-process communica• tion primitives have been implemented, including event flags, message buffers, shared memory and shared files. We believe this provides a good base for providing support for various operating system environments and for providing real-time response for processes. The UNIX time-sharing system has been implemented as one environment on the MERT system. This paper (*) provides an overview of the MERT system. * - Submitted to COMPCON Conference, September 7-9, 1975 Pages Text 11 Other 5 Total 16 _ DATE FILE COPY Bell Telephone Laboratories No. Figures 2 No. Tables O No. Refs. 4 _ Incorporated E-1932-0-4 (6-73) SEE REVERSE SIDE FOR DISTRIBUTION LIST LL TELl:.PHONE LA.bORATO.cUES, fo<:.

  • A JUNGIAN PERSPECTIVE by LAURA NANNETTE MOSLEY
    THE ROLE AND MEANING OF THE MELUSINE MYTH IN MODERN NARRATIVE: A JUNGIAN PERSPECTIVE by LAURA NANNETTE MOSLEY (Under the Direction of Jonathan F. Krell) ABSTRACT The myth of Mélusine first appeared in literary form in France in 1393. Its author, Jean d’Arras, drew from long-standing oral tradition in the writing of his romance, which was, by the standards of the Middle Ages, a best-seller. Mélusine’s ongoing popularity into the 20th and 21st centuries, not only in France, but internationally as well, is evidenced by André Breton’s Arcane 17 (1944), Manuel Mujica Lainez’s El unicornio (1965), Esther Tusquets’s El mismo mar de todos los veranos (1978), and Marie de la Montluel’s (Chantal Chawaf’s) Mélusine des détritus (2002), the four novels I undertake to explore in this dissertation. From a Jungian perspective, the ongoing appeal of Mélusine may be explained by the rich archetypal images and mythological motifs contained within her story, but to fully understand why these authors from such vastly different socio-cultural and historical backgrounds were so inspired by her, it is necessary to consider that each of these authors wrote at a time of personal and societal crisis. Jung teaches that it is at such times that the individual awakens to the need to probe the unconscious, and that it is then that the archetype most needed by the psyche will appear. Following Jungian scholar James Hillman, who identifies the alchemical Mercurius as the archetype of healing due to his capacity to unite opposites, I identify Mélusine with this archetype.
