These frameworks are particu-larly important for developing open systems in which not onlyfunctionality but architecture is reused across a family ofrelated applications. Unfortunately, the design frameworkshave inherent conflict between reuse and tailorability. Threeguidelines, namely, interoperability, extensibility, and distribu-tion, help to solve this conflict and design open system archi-tectures by identifying hot spots and contracts, thereby balanc-ing flexibility and tailorability. 4 Refs.

Cir-cumspection is therefore required when using them, especiallywhen they are used to audit thoroughly and periodically allthe routing tables of a network. This paper proposes a central-ized and a distributed algorithm for scheduling routing verifi-cation tests in SS7 networks. It suggests as well a telecommu-

Ž .Abstract: Cellular digital packet data CDPD offers on-the-gousers access to a low-cost widespread, wireless data network.CDPD can be overlaid on existing analog cellular systems, andshare their infrastructure equipment on a non-interferingbasis. CDPD provides two connectionless network services,the standard open systems interconnection connectionless net-work protocol and the Internet protocol.

Title: IMPLEMENTATION AND PERFORMANCE EVALUA-TION OF HIGH PERFORMANCE CMIP SOFTWARE OVERATM NETWORK

Ž .Abstract: As the Asynchronous Transfer Mode ATM tech-nology comes to be used widely, the Telecommunications

Ž .Management Network TMN over ATM networks becomesan important issue. Since TMN uses the OSI protocols includ-

Ž .ing the Common Management Information Protocol CMIP ,it is required to implement CMIP communication over ATMnetworks. In order to realize OSI over ATM, ITU-T SG13 hasstandardized the Service Specific Coordination Function for

Ž .Connection Oriented Network Service SSCF-CONS , ServiceŽ .Specific Connection Oriented Protocol SSCOP , and the Syn-

Ž .chronization and Coordination Function SCF . We have de-veloped the CMIP software over ATM networks adoptingthese protocols. The CMIP software is designed so that itachieves both high throughput for large data transfer andshort response time for small message exchange. The softwareadopts the implementation mechanisms commonly applied forprotocol modules to reduce the overheads for controlling OSIprotocol modules, and some protocol specific mechanismsespecially for protocols with heavy processing overheads, i.e.SSCOP and CMIP. The performance evaluation shows that

the developed CMIP software achieves more than 200 mes-sage exchanges per second for messages whose length is 64Byte long, and achieves about 36 Mbps throughput for trans-

Žferring data whose length is more than 100 KByte. Author.abstract 21 Refs. In English EI Order Number:

Title: TMN 2000: EVOLVING TMN AS GLOBAL TELECOM-MUNICATIONS PREPARES FOR THE NEXT MILLEN-NIUM

( )Author s : Willetts, Keith J.; Adams, Elizabeth K.Corporate Source: NMFSource: IEICE Transactions on Communications v E80-B n 6June 1997. p 796-804 CODEN: ITRCEC ISSN: 0916-8516Publication Year: 1997Abstract: The potential benefits of telecommunications man-

Ž .agement network TMN implementation as well as somepitfalls that must be addressed in order to gain its full poten-tial, including the technical evolution of the TMN framework,are discussed. The business reasons why telecommunicationsservice providers and network operators are moving to stan-dardize key aspects of the management of their networks andservices are reviewed. While TMN concentrates on anetwork-centric view, it is presented that a management whichis more responsive to fast and accurate customer response andoperational efficiency must be greatly considered without ne-glecting a direct response to clear business goals.

4. SOFTWARE QUALITY

A number of abstracts has been selected of a total of 167recently published papers to illustrate the spectrum of re-search, development, and application work in the area ofquality assurance. A wide range of aspects of software tech-nology and quality management issues is covered. Thus thebelow listed abstracts give a representative overview of cur-rent activities in important fields like software developmenttechniques, software tests, quality management of softwareprocesses and products, maintaining the quality of softwaresystems, services or products.

We did not try a subgrouping as in the other areas sinceoften in one paper, several aspects are dealt with. Therefore,the abstracts order is equivalent to the sequence on a PCscreen when searching www.ei.org based on the keyword soft-ware quality. Often mentioned additional keywords are: com-puter software, quality control, quality assurance, softwareengineering, user interface, cost effectiveness, reliability, erroranalysis, program debugging, product design, marketing, stan-dards.
