    Abstract
    The rapid growth of the Internet TCP/IP networks has encouraged the deployment of management products based on the Internet's Simple Network Management Protocol (SNMP). However, many organizations, including most telecommunications service providers, continue to define enterprise management solutions based on ISO/CCITT standard management and underlying Common Management Information Protocol (CMIP). Concludes that the key to achieving timely, effective, integrated management is to encourage a transition process aimed away from existing commercial investment in both ISO/CCITT and Internet based management technologies through deployment of common methods and tools which support integration

    Abstract
    Hinich and Molyneux review the literature of internet measurement and note three results consistently to be found in network traffic studies. These are "self-similarity," "long-range dependence," by which is meant that events in one time are correlated with events in a previous time and remain so through longer time periods than expected, and "heavy tails" by which they mean many small connections with low byte counts and a few long connections with large byte counts. The literature also suggests that conventional time series analysis is not helpful for network analysis. Using a single day's traffic at the Berkeley National Labs web server, cumulated TCP flows were collected, log transforms were used with the adding of .01 to all values allowing log transforms of the zero values, and providing a distribution that overcomes the heavy tail problem. However, Hinich's bicorrelation test for nonlinearity using overlapping moving windows found strong evidence of nonlinear structures. Time series analysis assumes linear systems theory and thus additivity and scalability. Spectral analysis should provide large peaks at the lowest frequencies if long range dependence is present since the power spectrum would go to infinity if the frequency goes to zero. This does not occur and so long range dependence must be questioned, at least until it is determined what effect other OSI layers may have on the TCP data.

    Abstract
    Describes a layer model for networks. For each layer, one or more services are defined, and for each service a protocol is specified. 2 OSI application level protocols have been defined for library services: SR and ILL. The underlying layers are supposed to be OSI services, but some implementations are using TCP/IP, and some are using a mixture of OSI and TCP/IP. The systems based directly on TCP/IP can not communicate with those based purely on OSI. Discusses the pros and cons for choosing OSI or TCP/IP. Gateways between the OSI and TCP/IP networks are needed. The ISO protocol SR and the ANSI protocol Z39.50 are both 'search and retrieve' protocols. The SR is almost a subst of Z39.50, but they may become identical in the future. There is only one protocol for interlibrary loan, the ISO ILL protocol. It covers 3 models of interlibrary loan and all services connected with ILL. Other services such as Explain, Scan and Update are presently being discussed in ISO TC 46. Discusses the needs of the library community for network services such as file transfer, remote login, directories and electronic mail

    Die Anbieter setzen auf unterschiedliche Hardware-Konzepte. Für Sipgate müssen die Kunden etwa ein spezielles IP-Telefon für 100 Euro kaufen. Zudem benötigen sie einen DSL-Router, um Telefon und Computer gleichzeitig verwenden zu können. Die Installation gestaltet sich schwierig, wenn der Router gleichzeitig mit einer Firewall-Komponente Viren- und Hackerangriffe aus dem Internet stoppen will - denn die User müssen diese Funktion für die Leitung zum IP-Telefon ausschalten. Beim Provider Freenet klappt das Telefonieren ohne Extrageräte: Wer plaudern will, verwendet eine Software am Computer, Mikrofon und Kopfhörer. Gewichtiger Nachteil dabei: Um erreichbar zu sein, muss der Rechner stets angeschaltet bleiben. Ein Anruf ins Festnetz kostet über die Hamburger deutschlandweit einen Cent je Minute, zum Handy 19 Cent. Gespräche zu anderen "iPhone"-Kunden sind frei. Eine bequeme Lösung stellt der Berliner Hersteller AVM auf der Cebit aus: Die "Fritz Box Fon" ist DSL-Modem, Router und Voice-over-IP-Telefonanlage in einem. Daran lassen sich zwei analoge Telefone anschließen. Wird das Gerät zusätzlich mit einem ISDN-Anschluss verbunden, können Anrufer mit einem Nummerncode auf Wunsch die herkömmliche Telefonverbindung anfordern - etwa wenn die am Sonntag kostenlos sind. Freenet will die AVM-Box vermarkten, auch der Montabaurer Provider 1 & 1 setzt auf sie. Interessant kann die Datentelefonie auch für unterwegs werden. Denn die Softwarelösungen laufen in Kürze auch auf den kleinen elektronischen Assistenten (PDA). Die gehen dann per Wireless LAN online. Die Mobilfunkbetreiber, die UMTS verkaufen wollen, wird das nicht freuen. Zumal mit 1&1 Deutschlands zweitgrößter DSL-Provider (bezogen auf die Kundenzahl) in Hannover ankündigt, seine Breitbandnutzer könnten bald von ausgewählten Stellen aus zehn Stunden pro Monat kostenlos über die Funktechnik ins Internet gehen. Das Telekommunikationsunternehmen Arcor hat ähnliche Pläne.

    Abstract
    Der neue 128-Bit-Header treibt die Möglichkeiten ins Astronomische: 3,4 mal zehn hoch 38 Adressen, eine 3,4 mit 38 Nullen. -Das IPv6-Forum zerhackte den Zahlentrumm in anschauliche Stücke: Pro Quadratmillimeter Erdoberfläche stehen nun zirka 667 Billiarden, pro Mensch 6,5 mal zehn hoch 28 Adressen, bereit." Eine Billiarde bringt es immerhin auf respektable 15 Nullen. Schon kurz darauf ging ein Aufschrei durch die Netzgemeinde. Das neue Protokoll schrieb die weltweit eindeutigen Seriennummern bestimmter Netzwerkkarten auf den virtuellen Adressaufkleber. Die Ethernet-Adapter bewerkstelligen den Datentransport bei Computern, die über eine Standleitung, ein Koaxialkabel, dauernd online sind. Die Spur von Ethernet-Usern wäre damit leicht zu verfolgen gewesen, ihre Nutzerprofile, ihre Surfgewohnheiten einsehbar wie offene Bücher. Das Problem, ließ Icann nun wissen, sei behoben: Es gebe keine festen Kennzahlen mehr in den Adressköpfen. Bei jedem Hochfahren eines Rechners oder sogar noch öfter werden die Nummern neu durchgemischt", erläutert Hans Petter Dittler, stellvertretender Vorsitzender der deutschen Sektion der Internet Society. Das Betriebssystem Linux kann bereits mit dem IPv6 arbeiten. Microsoft will den Standard in das nächste Windows-Betriebssystem einbauen: "Wir denken, der vorgeschlagene Standard ist wichtig zum Schutz der Privatsphäre der Internet-Nutzer", sagt Jawad Khaki, Vizepräsident für Netzwerke. Seit einigen Tagen steht auf der Microsoft-Homepage eine Vorab-Version von lPv6 für Windows 2000 zum Herunterladen bereit. Geradezu euphorisch gibt sich Protokoll-Chef Vint Cerf. Mit IPv6 haben wir die Grundlage dafür", philosophierte der Internet-Daddy auf dem ersten lPv6-Kongress 1999 in Berlin, "das Internet von unserem Planeten über den Mars und die Asteroiden bis in den Weltraum hinaus auszudehnen." Doch im Internet-Alltag wird das alte Protokoll noch lange Vorrang haben. Grund sind handfeste Programmier-Probleme. Denn Software, die sich explizit auf die vierte IP-Version bezieht, muss umgeschrieben werden - etwa um mit den längeren Adressfeldern umgehen zu können. Hubert Martens vom Münchner Multinet Services befürchtet gar einen InternetCrash: "Das Jahr-2000-Problem war harmlos gegen das, was uns mit lPv6 droht."
