Stateless RD Network Services
Rate-Delay (RD) Network Services constitute a promising differentiated-services architecture for multi-provider networks, by offering users a choice between high throughput or low queuing delay at bottleneck links. An RD router provides service differentiation via transmission scheduling and by managing two FIFO queues. To ensure strict delay bounds, an RD router tracks arrival times of packets...
متن کاملSwitching Costs and Network Compatibility
This paper investigates how consumer switching costs affect firms’ compatibility choices and social welfare in network industries. Firms face a choice between two modes of competition: make their networks incompatible and compete fiercely for market dominance, or make their networks compatible and have mild competition.

متن کاملRD-flatness and RD-injectivity
It is proved that every commutative ring whose RD-injective modules are Σ-RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of commutative rings for which each artinian (respectively simple) module is RD-injective, is given. These results can be obtained by using the properties of RD-flat modules and RD-coflat modules which are respectively th...
متن کاملIntegral Joins the 3 Rd Interplanetary Network
The BGO anticoincidence shield of the SPI detectors has a maximum effective area of over 5000 cm, and operates in the energy range >75 keV. It was incorporated into the 6spacecraft interplanetary network shortly after launch. It detects about one confirmed burst every three days, and has detected over 125 cosmic and soft gamma repeater bursts since it started operation. It also detects numerous...
