In public cloud networks, applications of different tenants compete for the shared network bandwidth and thus might suffer from unpredictable performance. It is desirable for cloud providers to offer tenants with bandwidth guarantees. However, it is challenging to precisely abstract tenant bandwidth requirements for their intra- and inter-tenant communications and to achieve work conservation simultaneously...
Sampling and reconstruction (S&R) are used in virtually all areas of science and technology. The classical sampling theorem is a theoretical foundation of S&R. However, for a long time, only sampling rates and ways of the sampled signals representation were derived from it. The fact that the design of S&R circuits (SCs and RCs) is based on a certain interpretation of the sampling theorem...
With the advancements in semiconductor chip manufacturing technology, it has been possible to put the various components of a system with more than one hundred processors, on a single chip. Network on chip (NoC) has been used as an effective communication platform for such systems. Due to the delays induced by routers and other equipment employed in NoC, the performance of communications for chips...
This paper presents a bandwidth-negotiation scheduling (BNS) for 802.16j MMR networks. The proposed BNS not only can allocate adequate bandwidth for UGS, rtPS, nrtPS, and BE in sequence of priority levels, but also can invoke negotiation between access and relay zones when the remaining bandwidth is insufficient to meet the minimum bandwidth requirement of rtPS or nrtPS. Besides, our BNS scheme can...
