An electronic marketplace with a distributed transaction layer may include such a plurality of distributed applications (12), where the applications (12) interact with one another using the distributed transaction layer (14) to conduct electronic commerce within the marketplace.

A method and apparatus are provided for monitoring and reporting cable connectivity such as patch panel port-level connectivity on a real-time basis. For patch panel systems, the approach is based upon a distributed architecture that may be modularly scalable and may reduce, if not eliminate, the need for a centralized signal processor and complex cabling between patch panels and the centralized signal processor. Each patch panel may determine port level connectivity independently. Polling delays and polling-related overhead processing may be reduced or eliminated by supporting real-time monitoring of port connectivity at the port level. The approach provides improved real-time reporting of patch panel connectivity with reduced cabling complexity, increased reliability, and decreased maintenance costs. In addition, the approach is compatible with (i.e., may communicate with and be controlled by) a multipurpose network management system (NMS). In addition, a compatible revision system is provided.

A resource distribution method capable of lending surplus resources among a plurality of services and reducing the maintenance cost of the surplus resources is provided. Computer resources in the standby system have a dead standby state in which at least an application is not installed. A plurality of services or a plurality of users share the computer resources in the standby system. As a result, improvement of the utilization factor of idle computer resources and server integration are implemented, and the cost required to maintain the computer resources is reduced. Furthermore, load prediction is conducted as regards individual services by using past operation history. Idle computer resources secured from services having surplus and maintained are thrown in according to a result of the prediction.

The present invention provides a cellular communication system that includes a central radio pool / traffic router (CRP / TR) that sends control and traffic signals over fiber optic transmission links that connect the CRP / TR with base stations of the cellular communication system. The high bandwidth capacity of each fiber link allows a large band of radio frequencies representing many radio channels to pass between the CRP / TR and individual base stations. Radio resources can be shared by all base stations in the cellular communication system, dynamically, when and where needed, to meet access demands throughout the system. The CRP / TR includes low-powered digital and / or analog radios and also switching and modulation means used to convey signals between the radios and various base stations within the system.

A network system and method include a wireless base station integrated at a central office of a service provider. The wireless base station is configured to provide portable and fixed services to customers. A passive optical network is coupled to the wireless base station at the central office to provide a link to extend an antenna for wireless operations of the wireless base station to a remote site such that a wireless signal from the wireless base station is transmitted in parallel with a passive fiber network signal through the link.

The invention discloses a masonry cement with high strength and water retention. According to the weight percentage, the masonry cement consists of 21-98.99 percent of porland cement clinker, 0-50 percent of blending materials, 1-12 percent of gypsum, 0.01-2 percent of cellulose ether and 0-15 percent of other additives. With the cellulose ether of high water retention material added, the water retention of the masonry cement is greatly improved. At the same time, through breaking through the limitation that the using amount of the blending materials in the original masonry cement is not less than 50 percent, the using amount of the blending materials is lowered to be 50 percent below to improve the strength of novel masonry cement. The strength of the prepared masonry cement is high, and the masonry cement with the strength grades of 12.5, 22.5, 52.5R, 62.5, 62.5R, etc. can be made. The hard problems of using low-grade blending materials to produce masonry cement with high water retention and using low- grade strength masonry cement of 12.5 and 22.5 to produce high-grade strength building mortar are solved.
