Traditionally, validation at the ASIC block level relies primarily upon simulation based verification. Specific components that are “hot spots” are then considered as candidates for Formal Verification. Under this usage model, the hurdles to Formal Verification are intractability and poor specifications. In this paper, we outline an alternate approach, where we used Formal Verification as the “first...
We study a performance improvement technique for the IEEE 1588 time synchronization system for Ethernet mobile backhaul. We propose and demonstrate the queuing delay estimation method by using dedicated probing packets to mitigate time synchronization deterioration caused by queuing delay in a packet switch. The demonstration results by numerical simulation show that the proposed method is effective...
With the rapid progress of high-performance cluster applications, data transfer between clusters in distant locations becomes more important. But, it is known that it is not easy to get good performance of data transfer using parallel TCP streams on long distance high bandwidth network. In this paper, we microscopically observe parallel TCP streams on 10 gigabit Ethernet (WGbE) network with a bottleneck,...
