As the 3D stacking technology still faces several challenges, the 2.5D stacking technology gains better application prospects nowadays. With the silicon interposer, the 2.5D stacking can improve the bandwidth and capacity of the memory system. To satisfy the communication requirements of the integrated memory system, the free routing resources in the interposer should be explored to implement an additional...
3D many-core NoCs are emerging architectures for future high-performance single chips due to its integration of many processor cores and memories by stacking multiple layers. In such architecture, because processor cores and memories reside in different locations (center, corner, edge, etc.), memory accesses behave differently due to their different communication distances, and the performance (latency)...
On-path caching has been proved to be effective in shortening the content retrieval time and educing the traffic workload imposed on the underlying network. In this paper, we study the effectiveness of on-path caching for the content distribution in the wireless network environment with GPSR as the underlying routing protocol. We extend the general cache network model introduced in [14] to account...
As wireless nodes become more powerful, a large volume of diverse content, such as images or videos, become available in a mobile ad hoc network (MANET). It follows that a MANET can largely benefit from the support for "range queries", i.e., a query for content whose attributes are within a requested range. Supporting range queries over MANET is challenging due to node mobility and adverse...
We consider a shadow routing based approach to the problem of real-time adaptive placement of virtual machines (VM) in large data centers (DC) within a network cloud. Such placement in particular has to respect vector packing constraints on the allocation of VMs to host physical machines (PM) within a DC, because each PM can potentially serve multiple VMs simultaneously. Shadow routing is attractive...
The Internet architecture lacks natural support for contentcentric applications, which are dominating Internet usage today. This led to the design and development of a plethora of application-specific and incompatible solutions for content distribution, e.g., content-delivery networks and peer-to-peer. More recently, information-centric architectures have been proposed to address the root causes of...
Delivery of high-quality streaming services over multi-hop wireless mesh networks (WMNs) is a challenging research problem because of quality fluctuation and interference of wireless links in WMNs, as well as strict throughput, delay, and reliability requirements of streaming applications. In this paper, we propose a Network Assisted Peer-to-Peer (NAP2P) system for file-based media streaming services...
