N-1-3-075.01, Internet Digest, by Deborah Estrin*, Internetworking: Research and Experience is a quarterly, refereed, journal published by Wiley (D. Comer, R. Droms, D. Estrin, and L. Svobodova are the Editors). In the first three issues of 1992 there are several papers of interest to the ISOC community. "An Empirical Workload Model for Driving Wide--Area TCP/IP Network Simulation", by P. B. Danzig, S. Jamin, R. Caceres, D. J. Mitzel, and D. Estrin (Volume 3, Number 1 (March 1992)), presents a workload model of internet traffic that can be used to drive simulation experiments. The model is based on analysis of wide-area TCP/IP traffic collected at several Internet sites. "An Implementation of the Revised Internet Stream Protocol (ST--2)", by C. Partridge, and S. Pink, (Volume 3, Number 1 (March 1992)), describes an experimental implementation of the ST-2 protocol in the BSD UNIX (TM) system. ST-2 was designed to support applications that require guaranteed network services by creating tree-shaped delivery paths with performance guarantees. "The EAN X.500 Directory Service" by G. Neufeld, B. Brachman, M. Goldberg, and D. Stickings, (Volume 3, Number 2 (June 1992)), describes experiences gained in implementing an OSI X.500 directory service. It points out a number of areas in the current OSI directory design that require further work and then describes how the EAN directory system has addressed these difficulties. "Myths about Congestion Management in High Speed Networks", by R. Jain, (Volume 3, Number 3 (September 1992)), is a position paper addressing addressing central issues in congestion control and avoidance for high-speed networks. "On Traffic Phase Effects in Packet--Switched Gateways", by S. Floyd, and V. Jacobsen, (Volume 3, Number 3 (September 1992)), describe how phase differences between competing traffic streams in a packet-switched network can be the dominant factor in relative throughput. They demonstrate how this discrimination can be eliminated with the addition of appropriate randomization to the network. We are planning two special issues for 1993. The first special issue on "Networking Support for Remote Conferencing" will focus on issues and experiences such as multicast protocols for remote conferencing, service requirements for remote conferencing data delivery and experiences with remote conferencing systems. The second special issue on "Dynamic Internetwork Architectures" will concentrate on issues such as addressing schemes for mobile hosts, routing in dynamic internet architectures and resource discovery and utilization by mobile hosts.
