Internet resource discovery services

K. Obraczka, P.B. Danzig, S.-H. Li
1993 Computer  
WAIS Clients translate user queries into the WAIS protocol and query the Directory of Services for relevant databases.  ...  Independent of the approach used, resource discovery services can also help users organize newfound information so that they can refer to it without having to repeat the entire discovery process.  ...  The Knowbot Information System (KlS) is an Internet directory service that understands a number of other directory services, such as X.500, and queries these services on behalf of users.

X.500 Performance with Large Databases and OSInet [chapter]

P. V. Rajeev, S. V Raghavan, Ashok K. Agrawala
1995 Computer Networks, Architecture and Applications  
The X.500 directory was originally designed for use with X.400 message handling systems (MHS) [CCITT (1988)].  ...  X.500 performance with large databases and OS/net 233 1 INTRODUCTION With the rapid expansion in the electronic communication, there is a growing need for an organized global information service.  ...  The X.500 implementation makes use of ROSE and ACSE of OSinet. The binding and unbinding to DSAs are done by using the ACSE. ROSE is used to invoke the directory operations.  ...

Fault-tolerant distributed shared memory on a broadcast-based architecture

C. Katsinis, D. Hecht
2004 IEEE Transactions on Parallel and Distributed Systems  
This paper uses extensive simulation to examine the performance of the SOME-Bus architecture under DSM and Backward Error Recovery.  ...  Under the distributed shared memory (DSM) paradigm, the SOME-bus allows strong integration of the transmitter, receiver and cache controller hardware to produce a highly integrated system-wide cache coherence  ...  A sequential consistency model is adopted and statically distributed directories are used to enforce a write-invalidate protocol.  ...

Comparative Evaluation of Latency-Tolerating and -Reducing Techniques for Hardware-Only and Software-Only Directory Protocols

Håkan Grahn, Per Stenström
2000 Journal of Parallel and Distributed Computing  
We find that while prefetching performs relatively worse on software-only directory protocols due to useless prefetches, there are examples of protocol optimizations, e.g., optimizations for migratory  ...  Since software-only directory protocols handle these operations in software they will perform relatively worse unless the technique reduces the number of protocol operations.  ...  A part of this work was carried out while the authors were at the Department of Computer Engineering at Lund University.  ...
