Technology makes it easier for us to communicate over a distance. However, there are still many remote areas that find difficult communicate. This is due the fact communication infrastructure in some expensive build while profit will be low. paper proposes combine voice internet protocol (VoIP) mesh network implemented on openWRT router. The routers performing functions. We set up VoIP server r...

Advances in semiconductor technology have let microprocessors integrate more than a 100 million transistors on a single chip. The Alpha 21364 microprocessor uses 152 million transistors to integrate an Alpha 21264 processor core, a 1.75-Mbyte second-level cache, cache coherence hardware, two memory controllers, and a multiprocessor router on a single die, as Figure 1a shows. In the 0.18-micron ...

A distributed multistage software router (MSSR) is composed by several interconnected software routers running on personal computers (PCs). The MSSR architecture overcomes scalability and performance issues of single software router by providing parallel forwarding paths. Like many networking devices, a MSSR must be sized for peak traffic load, which implies energy inefficiency at low loads. Th...

layer is the third component, the optical switch, which interconnects the core routers via a switched optical network layer over WDM links. While new high-availability (so-called “non-stop routing”) core routers provide service resiliency at the packet layer, the optical layer provides lowest cost and highest level of resiliency at the physical layer against catastrophic network events such as ...

introduction: as off pump coronary artery bypass grafting surgery (cabg) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. in this observational study we tried to show the rate and outcome of conversion . material and methods: in this descriptive study about 477 coronary off-pump cabg patients were operated in ghaem hos...

Network-on-chip (NoC) provides solution to overcome the complications of on-chip interconnect architecture in multi-core systems. It mainly consists router, links and network interface. An essential component router is an arbiter that significantly impacts performance router. The should provide fast fair arbitration when it placed Critical Path Delay (CPD) main aim this research work design a n...

Cyber attacks against the web management interface of Internet Things (IoT) devices often have serious consequences. Current research uses fuzzing technologies to test interfaces IoT devices. These fuzzers generate messages (a case sent from client server its functionality) without considering their dependency, which is unlikely bypass early check server. invalid cases significantly reduce effi...
