Proprietary QTP systems were developed for some of these applications due to the unavailability of commercial systems which could address the requirements of these systems. These QTP systems interconnect various applications running on heterogeneous software and hardware platforms, and have processed large transaction volumes for more than two decades. These applications communicate using structured messages which describe units of work in the QTP system. Vendor-developed Message Queueing Systems are now entering the marketplace. As new systems are developed using vendor solutions, portability and inter-operability among new and existing systems become an issue, especially on platforms where no vendor solutions exist. In this paper, we argue for an Open Systems Compatible Message Queueing System and propose an Open Systems architecture using an asynchronous message-passing facility. This architecture masks choices of operating system from applications as well as masking the more traditional choices of hardware. For complex, long-lived applications, this architecture is a requirement to ensure the success of the application - across both hardware and software platforms updates.","PeriodicalId":203232,"journal":{"name":"Proceeding of 13th IEEE Annual International Phoenix Conference on Computers and Communications","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115990649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In large distributed database systems, the same data are often replicated at multiple sites for quick data access and for high data availability. Because of the high cost of maintaining tight consistency of replicated data, most database systems choose to support loose consistency of replicated dam. The Sybase replication server is a transaction log based database replication system that allows row level data replication. It continuously propagates update transactions committed on the primary copy of data to the replicate copies stored in other databases. Unlike other data replication systems which are developed for specific database systems, the replication server is designed to be a separate process indcpendent of data servers which store the replicated dam. It provides an open system interface to communicate with heterogeneous data servers. The open system interface consists of two parts: the log transfer interface for accepting the log records for transactions executed on the primary copy of data, and the function string interface for users to translate commands in replicated transactions before they are applied to the databases containing replicate copies of data. The open log transfer interface makes it possible to replicate data from any databases that provide an interface to access their transaction logs. The open function string interface makes it easier to replicate data to databases through simple passthrough gateways. It also provides the flexibility for users to customize how transactions should be applied. We believe the replication server provides an important step towards providing practical solutions to data replication in large distributed database environments, most of which have data in heterogeneous databases.","PeriodicalId":203232,"journal":{"name":"Proceeding of 13th IEEE Annual International Phoenix Conference on Computers and Communications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115639601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonblocking broadcast networks have important applications in parallel and distributed processing. The network controller used for determining connection path routings figures critically in the performance of an interconnection network, particularly in real-time parallel and distributed processing applications. I n this paper, we will present designs of a network controller for the currently best available explicit constructions of nonblocking broadcast switching networks with a constant number of stages. For a three-stage nonblocking broadcast network of the type we consider wherein there are r switch modules in each of the first and third stages with n input ports and n output ports on each of these switch modules, i t will be seen that a network controller can determine connection path routings to satisfy a broadcast connection request in O( ,:if;,.) gate propagations. The designs will also be generalzzed to multi-stage networks in the same order of path routing time. This contrasts favorably with the O(nr) steps required in the previous software control algorithm. Furthermore, even the most hardware intensive of the controller designs is comparable in logic circuitry to that of one switching module. The network controller designs presented in this paper render the nonblocking broadcast networks we consider useful in real-time parallel and distributed processing applications which require high-speed network connection path set-ups.","PeriodicalId":203232,"journal":{"name":"Proceeding of 13th IEEE Annual International Phoenix Conference on Computers and Communications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129087302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
