Subject: n-1-4-075.01 Internetworking: Research and Experience Deborah Estrin, University of Southern California 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 upcoming two issues of the journal (last issue of 1992, and first issue of 1993) there are several papers of interest to the ISOC community: "Injecting Inter-autonomous system routes into Intra-autonomous system routing: a Performance Analysis", by Yakov Rekhter (IBM) and Bilal Chinoy (SDSC), evaluates a technique that injects only partial reachability information from inter-domain routing into intra-domain routing. When less inter-domain information is injected, more encapsulation may be needed in order to traverse the intra-domain portions of inter-domain paths. "Distributed Delay Jitter Control in Packet-Switching Internetworks", by Domenico Ferrari (UCBerkeley), proposes a mechanism for delay jitter control that can coexist with other schemes for jitter control (including no control) within the same network, the same node, and even the same real-time channel. THe mechanism guarantees low jitter even with loosely synchronized clocks and it makes the distribution of buffer space requirements more uniform along the route. "Design of an ATM-FDDI Gateway", by Sanjay Kapoor (Washington Univ), Milind Buddhikot (Washington Univ), and Gurudata Parulkar (Washington Univ), presents a detailed design of an gateway aimed at providing high performance internetworking between these two important classes of networks. The tasks are divided into critical path tasks, such as packet processing, for hardware implementation; and non-critical path tasks such as connection, resource, and route management, for software implementation. "Recent Changes to Privacy Enhanced Electronic Mail", by Matt Bishop (Dartmouth), is a short paper that describes the changes in message format and certificate based key management infrastructure for the PEM protocols which provide confidentiality, authenticity, and integrity for electronic mail.
