High throughput, low latency and high system availability are the most important criteria for an internet router. Internet Router‟s complexity has been on constant rise to serve the exploding internet backbone. With rise in design complexity comes the increased possibility of bugs escaping into silicon and affecting the user at runtime. In this project we provide a runtime verification scheme f...

Currently, most of Network on-Chip (NoC) architectures have some limitation in routing decisions. And it makes router nodes overloaded, and sequentially forms deadlock, livelock and congestion. A simple unbuffered router microarchitecture for S-mesh NoC architecture is proposed in this paper. Unbuffered router transforms message without making routing decision. Simulation results showed that S-...

Performance results and synthesized area overhead for a code division multiple access (CDMA) router intended for network-on-chip (NoC) applications are presented. Specific architectural block diagrams of the main components of the router are given and synthesis results are provided for 0.18 micron and 0.25 micron structured ASIC libraries. Post-synthesis VHDL simulations verify the functionalit...

An Internet router was integrated into the UK-DMC remote-sensing satellite as a secondary experimental payload. This commercial product has been orbiting in space for over three years. We describe the integration of the router and satellite and the successful on-orbit testing of the router, which took place using the Virtual Mission Operations Center (VMOC) application as part of a larger syste...

NoC designs are based on a compromise of latency, power dissipation or energy, usually defined at design time. However, setting all parameters at design time can cause either excessive power dissipation (originated by router underutilization), or a higher latency. The situation worsens whenever the application changes its communication pattern, i.e., a portable phone downloads a new service. Th...

On the Internet, two different IP protocols are deployed such as IPv4 [7] and IPv6 [1]. The Mobile Router uses the basic NEMO protocol [2] which is IPv6 protocol specific. During the early period of time that IPv6 transition is occurring it is very likely that a Mobile Router will move to an IPv4 only access network. When this occurs the Mobile Router will no longer be able to operate using the...

The Internet was created as a best effort service, however, there is now considerable interest in applications which transport time sensitive data across the network. This project looks into a novel network router architecture, which could improve the Quality of Service guarantees which can be provided to such flows. This router architecture makes use of virtual machine techniques, to assign an...

In this paper, we propose a multi-mode router, which supports three modes: bypass, bufferless and normal. By using the power gating technology, it can dynamically switch modes under different network loads, and effectively reduce the power consumption. Besides, in the bufferless mode, we propose an input priority judgment method and an output port allocation method to reduce the packet deflecti...

Due to the large number of I/O’s in a BallGrid-Array (BGA) package, routing becomes more and more an important work. A ring-based router for the BGA package is presented in this paper to interconnect each I/O pad of a chip to a corresponding ball distributed on the substrate area. The major phases for the router consist of layer assignment, topological routing, and physical routing. Using this ...

As network transmission speeds increase, packet streams increasingly uncover fine details of the interior behavior of router hardware and software. This behavior reveals itself as a set of harmonic effects, as interior clocks periodically interrupt packet forwarding, and interior queues periodically empty and fill. We examine this behavior with a Linux-based router employing a variety of gigabi...
