in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

Resources assigned to virtual network are not optimal resources, which are caused by some scarce resources. To solve this problem, this paper proposes a novel virtual network mapping algorithm that can realize mapping cost minimizing, called CMVNMA, based on two characteristics of network virtualization environment, that is virtual network has lifecycle and substrate network resources are incre...

Dynamic virtual network allocation is a promising traffic control model for cloud resident data center which offers virtual data centers for customers from the provider’s substrate cloud. Unfortunately, dynamic virtual network allocation designed in the past was aimed to the Internet so it needs distributed control methods to scale with such a large network. The price for the scalability of the...

Virtual network mapping is one of the main problems in network virtualization. At present, virtual networking mapping aims at minimal resource consumption at substrate network, but ignores the resource demanded by the hidden hops, making bottlenecks due to the resource shortage at the hidden hops. This paper aims at the simultaneous loading balance of the substrate node and the substrate link, ...

Network testbeds such as Emulab and the Open Network Laboratory use virtualization to enable users to define end user virtual networks within a shared substrate. This involves mapping users' virtual network nodes onto distinct substrate components and mapping virtual network links onto substrate paths. The mappings guarantee that different users' activities can not interfere with one another. T...

Based on the previous research, a virtual network mapping algorithm with repeatable embedding over substrate nodes is summarized, in which, the virtual nodes in the same virtual network may be assigned to the same substrate node so that some virtual links don’t need to be mapped to reduce the substrate link costs and improve the mapping effectively. Additionally, in the link mapping process, pa...
