Each object supports more abstract operations than the low-level read and write operations. The objects are replicated to increase the performance, reliability, and availability. In this paper we discuss a synchronization method to make multiple replicas of objects mutually consistent. In the traditional optimistic two-phase locking (02PL), every replica is first locked in a read mode to write an object. Finally, all the replicas are locked in a write mode when the transaction commits. We propose a novel object-based locking (OBL) method based on the abstract operations. Here, the number of the replicas locked is decided based on the access frequency and the strength of the lock mode.","PeriodicalId":239245,"journal":{"name":"Proceedings Twelfth International Conference on Information Networking (ICOIN-12)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116761820","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}

From the DSM-CC UN perspective, an ATM connection is merely one type of resource needed within a video on demand service session, but DSM-CC UN should use Q.2931 protocol to actually create the ATM connection.

In multicast communication, routing paths are established in terms of minimizing the total cost of the multicast tree or minimizing the distances of each connections from source to the destinations. In this paper, we also concern about the number of copies in one switching fabric and propose a new algorithm for multicast routing in which (1) it avoids concentration of copying at a specific exchange node and (2) it ensure the optimal path for longest connections among destinations. Time complexity and space complexity of the algorithm are discussed.","PeriodicalId":239245,"journal":{"name":"Proceedings Twelfth International Conference on Information Networking (ICOIN-12)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128455657","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}

However, ARQ protocols in group communications are not discussed, where multiple senders send packets to multiple receivers. In the group communication protocols, acknowledgments of packets received are piggy-backed by packets. Hence, the forward and feedback channels are considered to be combined to one bi-directional channel. In addition, since each process has the buffer both for retransmitting and for resequencing packets sent and received, efficient buffer allocation schemes have to be adopted. In this paper, we analyze the throughput of the ARQ protocol for the group communications.","PeriodicalId":239245,"journal":{"name":"Proceedings Twelfth International Conference on Information Networking (ICOIN-12)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128679464","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}

First, we propose a parallel queueing model with precedence, which makes sure that the high priority packets are dealt with within constant time no matter how the traffic load is. On the other hand, it ensures that the lost probability of the high priority packets is also very low. Next, we use MMM (mathematic model method) to analyse the system and use SOR (successive over-relaxation method) to compute the state probability of the system. Then we compare the precedence queueing scheme and the conventional queueing scheme where all packets are serviced at the same priority level. Then a conclusion is drawn that the former one takes obvious advantage than the latter one in the fields of queue length distribution, average blocking probability, and average waiting time. We also give out how to realize this proposal in the real application and that is by looking up a table constructed before. Finally we provide simulation results to help verify the validity of analysis. It is shown that we can get very good performance of high priority packets while the performance of low priority packets will not be very bad.","PeriodicalId":239245,"journal":{"name":"Proceedings Twelfth International Conference on Information Networking (ICOIN-12)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129261797","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}

We consider the multiple agents system which has two major parts.
