as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

In order to obtain close-to-reality Internet maps, IP aliases resolution allows identifying IP addresses belonging to the same router. Mainly, active probing is used for IP aliases resolution following direct and indirect schemes. Also, different types of probe packets are used (ICMP, UDP, etc.) focusing on different header fields and characteristics of IP and higher layers. Responsiveness of r...

One of key issues in the construction of a large-scale wireless sensor network (WSN) is how to securely allocate a unique address to each node in an energy-efficient manner. However, conventional network configuration mechanisms may suffer from energy inefficiency and/ or addressing failure problem when applied to the construction of large-scale WSNs. In this paper, we consider the construction...

In the context of MPLS TE Fast Reroute, the Merge Point (MP) address is required at the Point of Local Repair (PLR) in order to select a backup tunnel intersecting a fast reroutable Traffic Engineering Label Switched Path (TE LSP) on a downstream Label Switching Router (LSR). However, existing protocol mechanisms are not sufficient to find an MP address in multi-domain routing networks where a ...

The network layer in a computer network is responsible for providing a datagram service, in which a packet issued from a source node to a destination node is expected to reach the destination node in a reasonably short period of time with some probability. The datagram service does not provide delivery guarantees: these are expected to be provided by a higher level transport layer, on top of a ...

In computing field, demand of speed is going beyond the limit, thus to satisfy the high-end needs, multi-core processors are playing its crucial role. As far as multicore is concerned, there are few difficulties to be optimized for the promising future processor infrastructure, SoC(System on chip) based processor is being replaced with NoC(Network on Chip). NoC is expected to overcome the limit...

As the pressure to drive down network costs increases without compromising the stringent availability requirements imposed by service Level Agreements (SLAs), the development of advanced techniques to optimize the interaction between network layers becomes a necessity. To this end multi-layer networks have been investigated, influencing network design and provisioning. The requirements of high ...

Massive increases in IP (Internet Protocol) traffic have led to rapid deployment of IP-based networks in metropolitan (metro) areas. In order to facilitate this deployment, computer-based design tools are needed. One of the most difficult decisions that engineers face in designing an IP network is choosing the IP link topology (i.e., the set of router-to-router connections). This is especially ...

To enable reliable data delivery and balance load in the presence of failures, we propose a new mechanism that combines path protection and traffic engineering. The key benefit of our solution is its simplicity, allowing for fast recovery while imposing minimal requirements on the routers. To provide resilience against every failure scenario from a known set, we advocate using a fixed set of pa...

Please cite this article in press as: P.M. Yaghini Syst. Architect. (2010), doi:10.1016/j.sysarc.201 This paper presents comparison of transient fault effects in an asynchronous NoC router and a synchronous one. The experiment is based on simulation-based fault injection method to assess the fault-tolerant behavior of both architectures. The effort has been accomplished by employing fault injec...
