- N-1-2-075.01 Internet Digest by Deborah Estrin, <estrin@usc.edu>
-
-
- 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 last two issues of 1991 there were several papers of interest
- to the ISOC community.
-
- "BERGATE--Interconnection of MAP/TOP Networks via Broadband ISDN", by
- T. Luckenbach, GMD-FOKUS, describes a VMEbus system developed to
- support communication between distributed MAP/TOP networks by means of
- 140 Mbits/s channels provided by the Berkom test network. In addition,
- TCP/IP routing and end-system functionality is supported.
-
- "On the Efficient Implementation of Fair Queueing", by S. Keshav, AT&T
- Bell Laboratories, studies the data structures and algorithms for the
- efficient implementation of fair queueing. Fair queueing is a queue
- service discipline for routers and switches that has been shown to
- have several advantages over the traditional first-come-first-serve
- discipline. The paper presents a novel performance evaluation
- methodology and uses it to evaluate the relative merits of several
- alternate implementations.
-
- "Design and Evaluation of Inter-Domain Policy Routing Protocols", by
- L. Breslau and D. Estrin (University of Southern California),
- discusses inter-domain routing protocols in the context of three
- design parameters: location of routing decision, expression of policy,
- and algorithm used. Several routing architectures are described. The
- authors conclude that an architecture based upon source routing, a
- link state algorithm, and policy information in the link state
- advertisements is best able to support source-specific policies and
- special types of service. However, an architecture using a distance
- vector algorithm and hop by hop routing presents certain advantages
- when less policy control is needed.
-
- "Privacy-enhanced Electronic Mail", by M. Bishop, Dartmouth College,
- describes the mechanisms developed by the Internet Privacy and
- Security Research Group to provide security enhancements for
- electronic mail. The first set of mechanisms is a protocol to provide
- privacy, integrity, and authentication for electronic mail; the second
- is a certificate-based key management infrastructure to support key
- distribution throughout the internet. The paper describes and
- evaluates the mechanisms and discusses the reasons behind their
- selection.
