Today Enterprise application integration and information technology has become very critical for successful functioning of any enterprise in this world. The goal of enterprise application integration is to achieve data sharing, associated organic combination of data, using a unified platform for future large-scale enterprise information laid the foundation for the scale of integration. At first, this...
Windows-WMI technologies used by WMIC command to access and manage resources and to obtain the Windows Server System parameters required ,you can quickly find the value of various controlling parameters at the same time. The results of redirect WMIC saved to the database. This paper presents a technique based on WMIC to collect the data of surveillance server system and to achieve the key monitoring...
Short term and long term transactions will become very important for both personal and cooperative work involving workflows that use ontologies of the Semantic Web. We describe a way to get around the CAP theorem (the impossibility of simultaneous consistency, availability, and the possibility of network partitioning) and the worst-case infinite delay for any distributed decision-making.
SIP (session initial protocol) is a signaling protocol widely used in IP-based multimedia communication. Recently, P2PSIP reduces the deployment and maintenance cost, as well as improves the robustness and scalability of SIP-based system. SIP, P2PSIP network will coexist in the forthcoming future. This paper focuses on the P2PSIPand its relationship with SIP. We design and implement a P2PSIP adaptor,...
Many asynchronous distributed atomic commit protocols use a coordinator, either an application server or an elected database server, to handle the progress of a transaction. When the coordinator fails or the network becomes partitioned, the transaction may block or may suffer from a split brain syndrome. In this paper we propose a decentralized, collaborative, non-blocking atomic protocol, which piggybacks...
Session initiation protocol has been widely deployed to enable multimedia communication. To guarantee service reliability and scalability, service providers usually deploy SIP server farms. In this paper, we present a reliable and scalable DHT-based SIP server farm. In the proposed server farm, one-hop DHT is adopted and a new SIP event package called SIEP (server information event package) is designed...
This paper presents a suite of reliability mechanisms for P2PSIP-based conference services. These mechanisms can be divided into two categories. One is backup mechanism, which is designed to elect backup conference provider in a distributed and dynamic manner among all the participants of conference. The other category contains handover and failover mechanisms, which are designed to maintain continuous...
Many asynchronous distributed transactional systems use a coordinator, either an application server or an elected database server, to handle the progress of a transaction. When the coordinator fails or the network becomes partitioned, the transaction may block. In this paper we propose a ring-based transactional architecture for distributed database systems. The transaction can progress even if the...
In this paper, we propose a mechanism of using super consumers to manage reputation. Super consumers are consumers with more capabilities, such as cpu power, storage and bandwidth. Super consumers can serve as reputation managers to build global reputation for a service based on the opinions from all the members in the system. Super consumers can also build community-based reputation for a service,...
