Title
Vne2: A Virtual Network Embedding Framework Based On Equivalent Bandwidth In Fiber-Wireless Enhanced 5g Networks
Abstract
Fiber-Wireless (FiWi) enhanced 5G networks have gained a lot of popularity due to its advantageous anytime-anywhere access for end users with high bandwidth capacity and long distance. The scheduling and allocation of the heterogeneous resources in FiWi can be tackled through network virtualization. However, existing works on End-To-End (ETE) Quality of Service (QoS) guarantee of Virtual Network Embedding (VNE) ignore the random nature of network traffics, leading to non-negligible queuing delay. Moreover, the flexibility of resource allocation for link embedding is also ignored by constraining the same amount of allocated resources for all links on each physical path. In this paper, we highlight flexible and delay-guaranteed VNE design in FiWi enhanced 5G networks and propose a VNE framework based on Equivalent bandwidth (VNE2). The equivalent bandwidth is defined as a set of resources to be allocated to physical links on the path that a virtual link is embedded while guaranteeing ETE QoS. Furthermore, in order to bring the superiority of flexible resource allocation into full play, diversity of the amount of resources in the equivalent bandwidth for each virtual link is allowed to maximize Infrastructure Provider (InP) profit. Simulation results demonstrate that VNE2 can improve network performance in aspects of InP profit, virtual network acceptance ratio and ETE delay.
