A novel topology based on pentacle is proposed for network on chip (NoC). Johnson coding and global asynchronous local synchronous (GALS) are applied to improve the performance of NoC and the resource utilization of FPGA. Simulation results show that, compared with 2D Mesh and Octagon, Pentacle achieves average latency reductions of 30.7% and 15.0%, and increases throughput of 17.6% and 8.1%, respectively...
Due to its distributed and autonomous characteristics, it is difficult to change the Internet infrastructure in support of new services. In this context overlay networks provide a promising means of offering a supplement to the existing "best efforts" delivery mechanism. This paper discusses one of the key issues: topology construction in the context of provider-independent overlay networks...
Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By pre-configuring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance...
This paper proposes a Resilient Overlay for Mission Critical Applications (ROMCA); a novel operator-independent overlay architecture providing a resilient and reliable service across wide-area networks. One feature of ROMCA is that its overlay topology can be altered according to the underlying network conditions. Moreover, resilience is achieved by combining centralized topology construction control...
