In this paper, we propose a High Availability Open Shortest Path First (HA-OSPF) router which consists of two OSPF router modules, active and standby, to support a high availability network. First, we used the continuous-time Markov chain (CTMC) to analyze the steady-state availability of an HA-OSPF router with one active router and N standby routers (1 + N redundancy model). Then, with the fai...

Current router models [2, 3, 5, 6] assume that clock cycle time depends solely on router latency. However, in practice, routers are heavily pipelined, making cycle time largely independent of router latency. In this paper, we describe a router delay model that accurately accounts for pipelining based on technology-independent delay estimates derived through detailed gate-level analysis. Simulat...

We present the Block Storage Multi-Protocol Converter (BSMC) software architecture, which is able to translate and manage SCSI commands carried by different SCSI transport protocols, such as SCSI, Fibre Channel, and iSCSI, to a variety of storage devices. We discuss the internal organization of BSMC and present some performance testing results. We describe the variety of applications in Storage...

With the rapid increasing of network traffic, whether the router can be scalable is becoming the issue that people concern. The cluster-based scalable router can increase the capability infinitely in theory with linearly cost. Without the concentrated switch fabric, the operations of routing and forwarding are different from the typical crossbar router. The incoming packets usually pass through...

Mobile Ad Hoc NETworks (MANETs) consist of wireless mobile nodes, each of which can act as a router to relay data for others without a pre-existing infrastructure. In MANETs, both topology maintenance and energy efficiency are important, but have usually been addressed separately. This paper proposes a new dynamic clustering algorithm to address both energy conservation and topology maintenance...

Abstract One of the primary challenges in realizing large-scale quantum processors is realization qubit couplings that balance interaction strength, connectivity, and mode confinement. Moreover, it very desirable for device elements to be detachable, allowing components built, tested, replaced independently. In this work, we present a microwave state router, centered on parametrically driven, J...
