Though introducing the conception of “green” to optical networks, we discuss three key technologies to enhance the network energy efficiency rate (NEER), including General Multiple Protocols Label Switch (GMPLS), Passive Optical Network (PON), and Network Redundant Element Shutdown (NRES) technology. The optimization and improvement methods as well as the situation of application of the three technologies...
As a natural evolution of GIS (Geographic Information Systems) Web services GIS Grid services (GGS) are defined with common behaviors and semantics using a certain interface description language, which makes the Service-Oriented Architecture (SOA) and its runtime environment more flexible and manageable. A new concept of Pluggable Service is proposed in this paper, which aims to separate the static...
In this paper, a new utility-based uplink scheduling scheme for multiple services in CDMA systems is proposed. The scheduling criterion is to maximize the system utility which is the weighted sum of all user utilities. The weights of the users reflect their QoS levels and fairness requirements. The constraint conditions of the variables in the system utility function are obtained by the uplink transmission...
